一、安装mysql-5.0.45

#groupadd mysql
#useradd -g mysql -s /bin/false -M mysql
#tar zxvf mysql-5.0.45.tar.gz
#cd mysql-5.0.45

#./configure
–prefix=/usr/local/mysql
–enable-thread-safe-client
–enable-local-infile
–with-charset=gbk
–with-extra-charset=all
–with-low-memory
#make
#make install
#cp support-files/my-medium.cnf  /etc/my.cnf
#cd  /usr/local/mysql
#chown -R mysql .
#chgrp -R mysql .
#bin/mysql_install_db –user=mysql
#chown -R root .
#chown -R mysql var
#bin/mysqld_safe –user=mysql &

#cd  /usr/local/src/mysql-5.0.45
#cp  support/mysql.server  /etc/rc.d/init.d/mysqld
#chmod  700  /etc/rc.d/init.d/mysqld
加入自动启动服务队列：
#chkconfig –add mysqld
#chkconfig  –level  345  mysqld  on

测试
#/usr/local/mysql/bin/mysqladmin  ping
#/usr/local/mysql/bin/mysqladmin  version
#/usr/local/mysql/bin/mysql

添加root密码
#/usr/local/mysql/bin/mysqladmin -uroot -p 旧密码 password 新密码
说明：此时mysql的root用户的密码为空

配置库文件搜索路径
# echo “/usr/local/mysql/lib/mysql” >> /etc/ld.so.conf
# ldconfig -v

添加/usr/local/mysql/bin到环境变量PATH中
#export PATH=$PATH:/usr/local/mysql/bin

二、安装openssl-0.9.8e

# tar zxvf openssl-0.9.8e.tar.gz
# cd openssl-0.9.8e
# ./config shared zlib
# make
# make test
# make install
# mv /usr/bin/openssl /usr/bin/openssl.OFF
# mv /usr/include/openssl /usr/include/openssl.OFF
# rm /usr/lib/libssl.so
# ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
# ln -s /usr/local/ssl/include/openssl /usr/include/openssl
# ln -sv /usr/local/ssl/lib/libssl.so.0.9.8  /usr/lib/libssl.so

配置库文件搜索路径
# echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
# ldconfig -v

检测安装结果
# openssl version
OpenSSL 0.9.8e 23 Feb 2007

三、安装sasl-2.1.22

#tar zxvf cyrus-sasl-2.1.22.tar.gz
#cd cyrus-sasl-2.1.22
#./configure –prefix=/usr/local/sasl2 –disable-gssapi –disable-anon –disable-sample –disable-digest –enable-plain –enable-login –enable-sql –with-mysql=/usr/local/mysql –with-mysql-includes=/usr/local/mysql/include/mysql –with-mysql-libs=/usr/local/mysql/lib/mysql  –with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket
#make
#make install

关闭原有的sasl：
# mv /usr/lib/libsasl2.a  /usr/lib/libsasl2.a.OFF
# mv /usr/lib/libsasl2.la  /usr/lib/libsasl2.la.OFF
# mv /usr/lib/libsasl2.so.2.0.19  /usr/lib/libsasl2.so.2.0.19.OFF
# mv /usr/lib/sasl2  /usr/lib/sasl2.OFF
# rm /usr/lib/libsasl2.so
# rm /usr/lib/libsasl2.so.2

# ln -sv /usr/local/sasl2/lib/*  /usr/lib

postfix 2.3以后的版本会分别在/usr/local/lib和/usr/local/include中搜索sasl库文件及头文件，故还须将其链接至此目录中：
# ln -sv /usr/local/sasl2/lib/*  /usr/local/lib
# ln -sv /usr/local/sasl2/include/sasl/*  /usr/local/include

创建运行时需要的目录并调试启动
# mkdir -pv /var/state/saslauthd
# /usr/local/sasl2/sbin/saslauthd  -a  shadow  pam  -d

启动并测试
# /usr/local/sasl2/sbin/saslauthd -a shadow pam
# /usr/local/sasl2/sbin/testsaslauthd -u root -p root用户密码

配置库文件搜索路径
# echo “/usr/local/sasl2/lib” >> /etc/ld.so.conf
# echo “/usr/local/sasl2/lib/sasl2″ >> /etc/ld.so.conf
# ldconfig -v

开机自动启动
# echo “/usr/local/sasl2/sbin/saslauthd -a shadow pam”>>/etc/rc.local

四、安装BerkeleyDB

#tar zxvf db-4.5.20.tar.gz
#cd db-4.5.20/build_unix
#../dist/configure –prefix=/usr/local/BerkeleyDB
#make
#make install

修改相应的头文件指向
# mv  /usr/include/db4  /usr/inculde/db4.OFF
# rm  /usr/include/db_cxx.h
# rm  /usr/include/db.h
# rm  /usr/include/db_185.h
# ln -sv /usr/local/BerkeleyDB/include  /usr/include/db4
# ln -sv /usr/local/BerkeleyDB/include/db.h  /usr/include/db.h
# ln -sv /usr/local/BerkeleyDB/include/db_cxx.h  /usr/include/db_cxx.h

配置库文件搜索路径
# echo “/usr/local/BerkeleyDB/lib” >> /etc/ld.so.conf
# ldconfig –v

五、安装httpd-2.2.4

#tar jxvf httpd-2.2.4.tar.bz2
#cd httpd-2.2.4
#./configure
–prefix=/usr/local/apache
–enable-so
–enable-ssl
–with-ssl=/usr/local/ssl
–enable-track-vars
–enable-rewrite
–with-zlib
–enable-mods-shared=most
–enable-suexec                      (后面extmail切换”运行时用户”时要用到)
–with-suexec-caller=daemon
#make
#make install

#echo “/usr/local/apache/bin/apachectl start” >> /etc/rc.local(系统启动时服务自动启动)

六、安装php-5.2.3

# tar -zvxf php-5.2.3.tar.gz
# mkdir -p /usr/local/php
# cd php-5.2.3
# ./configure –prefix=/usr/local/php
–with-apxs2=/usr/local/apache/bin/apxs
–with-mysql=/usr/local/mysql
–with-mysqli=/usr/local/mysql/bin/mysql_config
–with-xml
–with-png
–with-jpeg
–with-zlib
–with-freetype
–with-gd
–enable-track-vars
–enable-mbstring=all
# make
# make install
# cp php.ini-dist  /usr/local/php/lib/php.ini

注：编辑apache配置文件httpd.conf，以apache支持php
# vi /etc/httpd/httpd.conf
1、添加如下二行
AddType application/x-httpd-php  .php
AddType application/x-httpd-php-source  .phps

2、定位至DirectoryIndex index.html
修改为：
DirectoryIndex  index.php  index.html

3、按照使用习惯，这里将网站根目录指定到/var/www：
找到DocumentRoot “/usr/local/apache/htdocs”
修改为：DocumentRoot “/var/www”(后文中我们还会注释掉此行，以启用虚拟主机)

找到<Directory “/usr/local/apache/htdocs”>
修改为：<Directory “/var/www”>

七、安装Postfix-2.4.5

1．安装
[root @ test root] # groupadd -g 2525 postfix

[root @ test root] # useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

[root @ test root] # groupadd -g 2526 postdrop

[root @ test root] # useradd -g postdrop -u 2526 -s /bin/false -M postdrop

[root @ test root] # service sendmail stop

[root @ test root] # mv /usr/sbin/sendmail /usr/sbin/sendmail.OFF

[root @ test root] # mv /usr/bin/mailq /usr/bin/mailq.OFF

[root @ test root] # mv /usr/bin/newaliases /usr/bin/newaliases.OFF

[root @ test root] # tar zxvf postfix-2.4.5.tar.gz

[root @ test root] #cd postfix-2.4.5

[root @ test postfix-2.4.5] # make makefiles ‘CCARGS=-DHAS_MYSQL

-I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -I/usr/local/BerkeleyDB/include  -DUSE_TLS -I/usr/local/ssl/include/openssl ‘ ‘AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/BerkeleyDB/lib -L/usr/local/ssl/lib -lssl -lcrypto’

[root @ test postfix-2.4.5] # make

[root @ test postfix-2.4.5] # make install

按照以下的提示输入相关的路径([]号中的是缺省值，”]”后的是输入值)

install_root: [/] /
tempdir: [/usr/local/src/ postfix-2.4.5] /tmp
config_directory: [/etc/postfix] /etc/postfix
daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec
command_directory: [/usr/sbin] /usr/local/postfix/sbin
queue_directory: [/var/spool/postfix]
sendmail_path: [/usr/sbin/sendmail]
newaliases_path: [/usr/bin/newaliases]
mailq_path: [/usr/bin/mailq]
mail_owner: [postfix]
setgid_group: [postdrop]
html_directory: [no] /var/www/postfix_html
manpages: [/usr/local/man] /usr/local/postfix/man
readme_directory: [no]

如图中红色框选处所示， postfix 提示在在加载共享库文件 libssl.so.0.9.8 时，发生错误，错误的原因是没有此文件，此时你就在系统中找一下，是否存在此文件啦，如果没有的话，就要安装啦，这个库文件与 openssl 有关。本例中此文件存放于 /usr/local/ssl/lib/ 目录下，这里需要将此目录写入到 /etc/ld.so.conf 文件中，然后运行 ldconfig 命令加载。步骤如下：
[root @test ~] # echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
[root @test ~] # ldconfig

注意：在编译时出现如下错误：

这是由于 postfix 找不到 mysql 的头文件所致，解决方法：
[root @test postfix-2.4.5] # mkdir /usr/local/mysql/include/mysql
[root @test postfix-2.4.5] # ln –s /usr/local/mysql/include/* /usr/local/mysql/include/mysql
[root @ test postfix-2.4.5] # chown –R mysql.mysql /usr/local/mysql/include/mysql
3、        出现如下错误：

这是由于 postfix 找不到 mysql 的库文件引起，解决方法：
[root @test ~] # mkdir /usr/local/mysql/lib/mysql
[root @test ~] # ln –s /usr/local/mysql/lib/* /usr/local/mysql/lib/mysql
[root @test ~] # chown –R mysql.msyql /usr/local/mysql/lib/mysql
说明：这里的postfix将安装在独立的目录/usr/local/postfix中，目的是为了方便管理；您亦可以采用默认安装的方式，可能这样使用起来会更为方便些；

生成别名二进制文件，这个步骤如果忽略，会造成postfix效率极低：
#  newaliases

配置 postfix

[root @ test postfix-2.4.5] # vi /etc/postfix/main.cf

myhostname = mail.test.com

mydomain = test.com

myorigin = $mydomain

inet_interfaces = all

mynetworks = 192.168.98.0/24, 127.0.0.0/8

#================Virtual Setting ====================

virtual_mailbox_base = /var/mailbox/

virtual_mailbox_maps= mysql:/etc/postfix/mysql/mysql_virtual_mailbox_maps.cf

virtual_mailbox_domains=mysql:/etc/postfix/mysql/mysql_virtual_domains_maps.cf

virtual_alias_domains =

virtual_alias_maps = mysql:/etc/postfix/mysql/mysql_virtual_alias_maps.cf

virtual_uid_maps = static:2525

virtual_gid_maps = static:2525

virtual_transport = virtual

maildrop_destination_recipient_limit = 1

maildrop_destination_concurrency_limit = 1

#=================Quota Setting ====================

message_size_limit = 14336000

virtual_mailbox_limit = 20971520

virtual_create_maildirsize = yes

virtual_mailbox_extended = yes

virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql/mysql_virtual_mailbox_limit_maps.cf

virtual_mailbox_limit_override = yes

virtual_maildir_limit_message = Sorry,the user’s maildir has overdrawn his diskspace quota,please Tidy your mailbox and try again later.

virtual_overquota_bounce = yes

#=================== Cyrus-sasl=====================

smtpd_sasl_local_domain = $myhostname

smtpd_sasl_security_options = noanonymous

smtpd_sasl_application_name = smtpd

smtpd_banner = Welcome to our $myhostname ESMTP, Warning:Version not Available!

[root @ test postfix-2.4.5] # mkdir -p /etc/postfix/mysql

[root @ test postfix-2.4.5] # cd /etc/postfix/mysql

说明：1、这里用到的数据库及用户的建立可以后文中的extmail说明部分来实现，您可以参照那一部分来理解这里指定的数据库及其用户名等；2、以上新建文件亦可以从extman安装文件中获得，您也可以由此不用手动输入；3、虚拟用户邮箱目录我这里沿用了/home/domains，你可以指定为别的目录，比如常见到的/var/mailbox，或者/home/domains等；但如果这里做了修改，请在后文中用到时作了相应的修改；

十、安装Courier authentication library

# tar jxvf courier-authlib-0.59.3.tar.bz2

# cd courier-authlib-0.59.3

./configure –prefix=/usr/local/courier-authlib  –sysconfdir=/etc –without-authpam –without-authldap –without-authpwd –without-authshadow  –without-authvchkpw –without-authpgsql –with-authmysql=/usr/local/mysql/lib/mysql –with-mysql-libs=/usr/local/mysql/lib/mysql –with-mysql-includes=/usr/local/mysql/include/mysql –with-redhat –with-authmysqlrc=/etc/authmysqlrc –with-authdaemonrc=/etc/authdaemonrc  CFLAGS=”-march=i686 -O2 -fexpensive-optimizations”  CXXFLAGS=”-march=i686 -O2 -fexpensive-optimizations”

# make

# make install

如果编译是说gdbm错误，需要安装

yum install gdbm gdbm-devel

# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon

# cp /etc/authdaemonrc.dist  /etc/authdaemonrc

# cp /etc/authmysqlrc.dist  /etc/authmysqlrc

修改/etc/authdaemonrc 文件

authmodulelist=”authmysql”

authmodulelistorig=”authmysql”

daemons=10

编辑/etc/authmysqlrc 为以下内容，其中2525，2525 为postfix 用户的UID和GID。

MYSQL_SERVER localhost

MYSQL_PORT 3306                   (指定你的mysql监听的端口，这里使用默认的3306)

MYSQL_USERNAME  extmail      (这时为后文要用的数据库的所有者的用户名)

MYSQL_PASSWORD extmail        (密码)

MYSQL_SOCKET  /tmp/mysql.sock

MYSQL_DATABASE  extmail

MYSQL_USER_TABLE  mailbox

MYSQL_CRYPT_PWFIELD  password

MYSQL_UID_FIELD  ’2525′

MYSQL_GID_FIELD  ’2525′

MYSQL_LOGIN_FIELD  username

MYSQL_HOME_FIELD  concat(‘/home/domains/’,homedir)

MYSQL_NAME_FIELD  name

MYSQL_MAILDIR_FIELD  concat(‘/home/domains/’,maildir)

# cp courier-authlib.sysvinit /etc/init.d/courier-authlib

# chmod 755 /etc/init.d/courier-authlib

# chkconfig –add courier-authlib

# chkconfig –level 2345 courier-authlib on

#echo “/usr/local/courier-authlib/lib/courier-authlib” >> /etc/ld.so.conf

# ldconfig -v

# service courier-authlib start   (启动服务)

十一、安装Courier-IMAP-4.1.3

# tar jxvf courier-imap-4.1.3.tar.bz2
# cd courier-imap-4.1.3
./configure 
–prefix=/usr/local/courier-imap 
–with-redhat 
–enable-unicode 
–disable-root-check 
–with-trashquota 
–without-ipv6 
CPPFLAGS=’-I/usr/local/ssl/include/openssl  -I/usr/local/courier-authlib/include’   
LDFLAGS=’-L/usr/local/courier-authlib/lib/courier-authlib’  
COURIERAUTHCONFIG=’/usr/local/courier-authlib/bin/courierauthconfig’ 
# make
# make install

如果在这一步出现错误：

因为编译安装的openssl的头文件链接指定问题。默认情况下，courier-imap编译时到/usr/include下查找openssl的头文件，到/usr/lib 下查找 openssl 的库文件，这里你要查找在这两个目录下是否存在 openssl 的库文件与头文件，openssl 的头文件是 /usr/include/openssl 该文件是链接到 /urs/local/ssl/include/openssl 。openssl的库文件是 /usr/lib/libssl.so 该文件是链接到 /usr/local/ssl/lib/libssl.so.0.9.8 。如没有的，请自行链接，如下：

[root @test ~] # ln –s /usr/local/ssl/include/openssl /urs/include/openssl

[root @test ~] # ln –s /usr/local/ssl/lib/libssl.so.0.9.8 /usr/lib/libssl.so

# cp /usr/local/courier-imap/etc/imapd.dist /usr/local/courier-imap/etc/imapd
# cp /usr/local/courier-imap/etc/imapd-ssl.dist /usr/local/courier-imap/etc/imapd-ssl
# cp /usr/local/courier-imap/etc/pop3d.dist /usr/local/courier-imap/etc/pop3d 
# cp /usr/local/courier-imap/etc/pop3d-ssl.dist /usr/local/courier-imap/etc/pop3d-ssl

配置Courier-IMAP，为用户提供pop3服务：
vi /usr/local/courier-imap/etc/pop3d
POP3DSTART=YES

注：如果你想为用户提供IMAP服务，则需在”/usr/local/courier-imap/etc/imapd”文件中设置”IMAPDSTART=yes”；其它类同；

新建虚拟用户邮箱所在的目录，并将其权限赋予postfix用户：
#mkdir –pv /home/domains
#chown –R postfix /home/domains

#cp courier-imap.sysvinit /etc/rc.d/init.d/courier-imapd
#chmod 755 /etc/rc.d/init.d/courier-imapd
#chkconfig –add courier-imapd
#chkconfig –level 2345 courier-imapd on
#service courier-imapd start

接下来重新配置SMTP 认证，编辑 /usr/local/lib/sasl2/smtpd.conf ，确保其为以下内容：
pwcheck_method: authdaemond
log_level: 3
mech_list:PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket

[root @ test courier-imap-4.1.3]  # mkdir –p /home/domains
[root @ test courier-imap-4.1.3]  #chown –R postfix /home/domains

[root @ test courier-imap-4.1.3]  # cp courier-imap.sysvinit /etc/rc.d/init.d/imapd
[root @ test courier-imap-4.1.3]  # chmod 755 /etc/rc.d/init.d/imapd
[root @ test courier-imap-4.1.3]  # chkconfig —add imapd
[root @ test courier-imap-4.1.3]  # chkconfig —level 2345 imapd on
[root @ test courier-imap-4.1.3]  # service imapd start

十二、安装 extmail

[root @test root] # tar zxvf extmail-1.2.tar.gz

[root @test root] # mkdir -pv /var/www/extsuite

[root @test root] # mv extmail-1.2 /var/www/extsuite/extmail

[root @test root]# cp /var/www/extsuite/extmail/webmail.cf.default  /var/www/extsuite/extmail/webmail.cf

修改主配置文件

[root @test root] # vi /var/www/extsuite/extmail/webmail.cf

部分修改选项的说明：

SYS_MESSAGE_SIZE_LIMIT = 5242880

用户可以发送的最大邮件

SYS_USER_LANG = en_US

语言选项，可改作：

SYS_USER_LANG = zh_CN

SYS_MAILDIR_BASE = /home/domains

此处即为您在前文所设置的用户邮件的存放目录，可改作：

SYS_MAILDIR_BASE = /var/mailbox/

SYS_MYSQL_USER = db_user

SYS_MYSQL_PASS = db_pass

以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库，这里修改为：

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_HOST = localhost

指明数据库服务器主机名，这里默认即可

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

连接数据库的sock文件位置，这里修改为：

SYS_MYSQL_SOCKET = /tmp/mysql.sock

SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password

以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称；这里默认即可

SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket

此句用来指明authdaemo socket文件的位置，这里修改为：

SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

apache相关配置

[root @test root] # vi /usr/local/apache/conf/httpd.conf

将 User daemon

Group daemon

改为

User postfix

Group postfix

将Include conf/extra/httpd-vhosts.conf

前的注释去掉，打开 apache 的虚拟主机功能。

# virtual hosts

Include conf/extra/httpd-vhosts.conf

编辑虚拟主机配置文件

<VirtualHost *:8080>

ServerName mail.szpian.com

DocumentRoot /var/www/extsuite/extmail/html/

ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi

Alias /extmail /var/www/extsuite/extmail/html

ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi

Alias /extman /var/www/extsuite/extman/html

<Directory “/var/www”>

Order Deny,Allow

allow from All

</Directory>

</VirtualHost>

依赖关系的解决

extmail将会用到perl的DBD::Mysql和Unix::syslogd功能，您可以去http://search.cpan.org搜索下载原码包进行安装。

[root @ test root] # tar zxvf Unix-Syslog-0.100.tar.gz

[root @ test root] # cd Unix-Syslog-0.100

[root @ test Unix-Syslog-0.100] # perl Makefile.PL

[root @ test Unix-Syslog-0.100] # make

[root @ test Unix-Syslog-0.100] # make install

DBD-Mysql目前最新的版本为DBD-mysql-4.005，但它和系统中的perl结合使用时会造成extmail无法正常使用，因此我们采用3的版本：

[root @ test root] # tar zxvf DBD-mysql-3.0002_4.tar.gz

[root @ test root] # cd DBD-mysql-3.0002_4

[root @ test DBD-mysql-3.0002_4] # perl Makefile.PL   (此步骤中如果出现类同Can’t exec “mysql_config”: No such file or directory at Makefile.PL line 76.的错误是因为您的mysql的bin目录没有输出至$PATH环境变量 看编译错误路径)

[root @ test DBD-mysql-3.0002_4] # make

//////************************** 注 意 *******************************

如编译时出现如下错误：

这是由于 DBD-mysql 默认是从 /usr/lib/mysql 查找 mysql 的库文件，而我们的 mysql 的库文件是存放在 /usr/local/mysql/lib/mysql 目录下，解决方法：

[root @test ~] # mv /usr/llib/mysql /usr/lib/mysql.bak

[root @test ~] # mkdir /usr/lib/mysql

[root @test ~] # ln –s /usr/local/mysql/lib/* /usr/lib/mysql

***********************************************************\\\\\\\\\\\\\\\\\\\

[root @ test DBD-mysql-3.0002_4] # make install

好了，到此为止，您的Webmail已经可以使用了，可以在浏览器中输入指定的虚拟主机的名称进行访问

十三、安装Extman-0.2.2

安装及基本配置

[root @ test root] #tar zxvf  extman-0.2.2.tar.gz

[root @ test root] # mv extman-0.2.2 /var/www/extsuite/extman

修改配置文件以符合本例的需要：

[root @test root] # vi /var/www/extsuite/extman/webman.cf

SYS_MAILDIR_BASE = /home/domains

此处即为您在前文所设置的用户邮件的存放目录，可改作：

SYS_MAILDIR_BASE = /var/mailbox/

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

此处修改为：

SYS_MYSQL_SOCKET = /tmp/mysql.sock

使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：

[root @test root] # cd /var/www/extsuite/extman/docs

[root @test docs ] # /usr/local/mysql/bin/mysql -u root  < extmail.sql

[root @test docs] # /usr/local/mysql/bin/mysql  -u root -p < init.sql

Enter password: 输入 mysql root 用户的密码

修改cgi目录的属主：

[root @test extman ] # chown -R postfix.postfix /var/www/extsuite/extman/cgi/

如果extman访问数据库权限不足的话，可采用以下命令将新生成的数据库赋予webman用户具有所有权限：

[root @test extman ] # /usr/local/mysql/bin/mysql

mysql> use extmail;

mysql> GRANT all privileges on extmail.* TO webman@localhost IDENTIFIED BY ‘webman’;

mysql> GRANT all privileges on extmail.* TO webman@127.0.0.1 IDENTIFIED BY ‘webman’;

mysql> GRANT all privileges on extmail.* TO extmail@localhost IDENTIFIED BY ‘extmail’;

mysql> GRANT all privileges on extmail.* TO extmail@127.0.0.1 IDENTIFIED BY ‘extmail’;

mysql> quit

在apache的虚拟主机配置文件中Extmail的虚拟主机部分，添加如下两行：

[root @test extman ] # vi /usr/local/apache/conf/extra/httpd-vhosts.conf

ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi

Alias /extman /var/www/extsuite/extman/html

启动所有服务：

[root @test root] # service mysqld start

[root @test root] # /usr/local/apache/bin/apachectl start

[root @test root] # service courier-authlib start

[root @test root] # service imapd start

[root @test root] # postfix start

mkdir -p /tmp/extman

chmod 777 /tmp/extman

在IE 浏览器中输入 http://192.168.98.204/extman ,进入邮件服务器的后台,添加域与添加用户邮箱。默认管理帐号为：root@extmail.org 密码为：extmail*123*。

说明：

(1) 如果您安装后无法正常显示校验码，安装perl-GD模块会解决这个问题。如果想简单，您可以到以下地址下载适合您的平台的rpm包，安装即可：  http://dries.ulyssis.org/rpm/packages/perl-GD/info.html

(2) extman-0.2.2自带了图形化显示日志的功能；此功能需要rrdtool的支持，您需要安装这些模块才可能正常显示图形日志。

接下来安装图形日志的运行所需要的软件包Time::HiRes、File::Tail和rrdtool，其中前两个包您可以去http://search.cpan.org搜索并下载获得，后一个包您可以到 http://oss.oetiker.ch/rrdtool/pub/?M=D下载获得； 注意安装顺序不能改换。

12、安装Time::HiRes

[root @test root] # tar zxvf Time-HiRes-1.9707.tar.gz

[root @test root] # cd Time-HiRes-1.9707

[root @test Time-HiRes-1.9707] # perl Makefile.PL

[root @test Time-HiRes-1.9707] # make

[root @test Time-HiRes-1.9707] # make test

[root @test Time-HiRes-1.9707] # make install

13、安装File::Tail

[root @test root] # tar zxvf File-Tail-0.99.3.tar.gz

[root @test root] # cd File-Tail-0.99.3

[root @test File-Tail-0.99.3] # perl Makefile

[root @test File-Tail-0.99.3] # make

[root @test File-Tail-0.99.3] #make test

[root @test File-Tail-0.99.3] # make install

在安装 rrdtool 之前，就确定你的系统中是否已经安装 tcl、tcl-devel、libart、libart-devel,用下面的命令检查是否已经安装

[root @test File-Tail-0.99.3] # rpm -qa | grep tcl

[root @test File-Tail-0.99.3] # rpm -qa | grep libart

如果没有安装，将 RedHat AS 4.0 光碟放入光驱，挂载安装。注：相关的安装包在第3张碟和第4张碟中。

14、安装rrdtool-1.2.23

#tar zxvf rrdtool-1.2.23.tar.gz

#cd rrdtool-1.2.23

#./configure –prefix=/usr/local/rrdtool

#make

#make install

创建必要的符号链接(Extman会到这些路径下找相关的库文件)

#ln -sv /usr/local/rrdtool/lib/perl/5.8.5/i386-linux-thread-multi/auto/RRDs/RRDs.so   /usr/lib/perl5/5.8.5/i386-linux-thread-multi/

#ln -sv /usr/local/rrdtool/lib/perl/5.8.5/RRDp.pm   /usr/lib/perl5/5.8.5

#ln -sv /usr/local/rrdtool/lib/perl/5.8.5/i386-linux-thread-multi/RRDs.pm   /usr/lib/perl5/5.8.5

复制mailgraph_ext到/usr/local，并启动之

# cp -r /var/www/extsuite/extman/addon/mailgraph_ext  /usr/local

# / usr/local/mailgraph_ext/mailgraph-init  start

若出现rrds.pm 错误 请执行以下命令

cp -rp /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/* /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/

# /usr/local/mailgraph_ext/qmonitor-init  start

添加到自动启动队列

echo “/usr/local/mailgraph_ext/mailgraph-init start” >> /etc/rc.local

echo “/usr/local/mailgraph_ext/qmonitor-init start” >> /etc/rc.local

好了，接下来您就可以到extman的后台查看图表日志了。局部效果如下图：

测试 smtp

通过以下命令获得 test@test.com 的用户名和密码的BASE64        编码

获得用户名BASE64编码

[root @test root] # perl -e ‘use MIME::Base64; print encode_base64(“test\@test.com”)’

dGVzdEB0ZXN0LmNvbQ==

获得密码BASE64编码

[root @test root] # perl -e ‘use MIME::Base64; print encode_base64(“test”)’

dGVzdA==

[root @test root] # telnet localhost 25

注：以上蓝色部分是自己输入的命令。

启动所有服务：

[root @test root] # service mysqld start

[root @test root] # /usr/local/apache/bin/apachectl start

[root @test root] # service courier-authlib start

[root @test root] # service imapd start

[root @test root] # postfix start

至此，邮件系统算是基本成型，已经可以用邮件服务器收发邮件啦.

开始安装 maildrop

[root @test pcre-7.4] # groupadd -g 1001 vmail

[root @test pcre-7.4] # useradd -g vmail -u 1001 -M -s /bin/nologin vmail

[root @test pcre-7.4] # cd

[root @test root] #  tar jxvf maildrop-2.0.2.tar.bz2

[root @test root] # cd maildrop-2.0.2

[root @test maildrop-2.0.2] #   ./configure –prefix=/usr/local/maildrop –enable-sendmail=/usr/sbin/sendmail –enable-trusted-users=’root vmail’ –enable-syslog=1 –enable-maildirquota –enable-maildrop-uid=1001 –enable-maildrop-gid=1001 –with-trashquota –with-dirsync

[root @test maildrop-2.0.2] # make

[root @test maildrop-2.0.2] # make install

[root @test maildrop-2.0.2] # cp /usr/local/maildrop/bin/maildrop /usr/bin

运行 maildrop -v ,检查安装结果，请确保有“Courier Authentication Library extension enabled”这一句出现

[root @test maildrop-2.0.2] # maildrop -v

maildrop 2.0.2 Copyright 1998-2005 Double Precision, Inc.

License. See COPYING for additional information.

新建配置文件 /etc/maildroprc,首先指定 maildrop 的日志文件存放地点

[root @test maildrop-2.0.2] # vi /etc/maildroprc

添加：

logfile “/var/log/maildrop.log”

[root @test maildrop-2.0.2] # touch /var/log/maildrop.log

[root @test maildrop-2.0.2] # chown vmail.vmail /var/log/maildrop.log

配置 postfix，

编辑 /etc/postfix/master.cf

[root @test maildrop-2.0.2] # vi /etc/postfix/master.cf

启用下面这两行，将前面的注释符号去掉

maildrop  unix  -       n       n       –       –       pipe

flags=DRhu user=vmail argv=/usr/local/maildrop/bin/maildrop -d ${recipient}

编辑 /etc/postfix/main.cf

[root @test maildrop-2.0.2] # vi /etc/postfix/main.cf

将

virtual_transport = virtual

修改为

virtual_transport = maildrop

编辑 authmysqlrc文件

[root @test maildrop-2.0.2] #  vi /usr/local/courier-authlib/etc/authlib/authmysqlrc

将

MYSQL_UID_FIELD         ’2525′

MYSQL_GID_FIELD         ’2525′

修改为

MYSQL_UID_FIELD         ’1001’

MYSQL_GID_FIELD         ’1001′

注意：如果没有修改此处，maildrop 可能会报“signal 0×06” 的错误报告

这一项需要重启验证服务

service courier-authlib restart

编辑 apache 的配置文件

[root @test maildrop-2.0.2] # vi /usr/local/apache/conf/httpd.conf

将

User postfix

Group postfix

修改成

User vmail

Group vmail

将用户邮件所在目录 /var/mailbox 和 extman 的临时目录 /tmp/extman 的属主和属组指定为 vmail

[root @test maildrop-2.0.2] # chown -R vmail.vmail /var/mailbox

[root @test maildrop-2.0.2] # chown -R vmail.vmail /tmp/extman

重新启动 apache 和 postfix

[root @test maildrop-2.0.2] # /usr/local/apache/bin/apachectl restart

如果没有重新启动 apache,将不能通过 web 收发邮件，提示如下错误：

[root @test maildrop-2.0.2] # postfix reload
