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--
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     (这里的目录指的是原压缩包解压后的目录)
#cp  support-files/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            (注意使用续行符)
--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
--sysconfdir=/etc/httpd
--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”>

说明:这个对本文来说并非是不可少的。

七、安装Postfix-2.4.5

1.安装
#groupadd -g 2525 postfix
#useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
#groupadd -g 2526 postdrop
#useradd -g postdrop -u 2526 -s /bin/false -M postdrop

#tar zxvf postfix-2.4.5.tar.gz
#cd 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'
#make
#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]

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

2.进行一些基本配置,测试启动postfix并进行发信
#vi /etc/postfix/main.cf
修改以下几项为您需要的配置
myhostname = mail.benet.org
myorigin = benet.org
mydomain = benet.org
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 192.168.1.0/24, 127.0.0.0/8

说明:
myorigin参数用来指明发件人所在的域名;
mydestination参数指定postfix接收邮件时收件人的域名,即您的postfix系统要接收到哪个域名的邮件;
myhostname 参数指定运行postfix邮件系统的主机的主机名,默认情况下,其值被设定为本地机器名;
mydomain参数指定您的域名,默认情况下,postfix将myhostname的第一部分删除而作为mydomain的值;
mynetworks 参数指定你所在的网络的网络地址,postfix系统根据其值来区别用户是远程的还是本地的,如果是本地网络用户则允许其访问;
inet_interfaces 参数指定postfix系统监听的网络接口;

注意:
1、在postfix的配置文件中,参数行和注释行是不能处在同一行中的;
2、任何一个参数的值都不需要加引号,否则,引号将会被当作参数值的一部分来使用;
3、每修改参数及其值后执行 postfix reload 即可令其生效;但若修改了inet_interfaces,则需重新启动postfix;
4、如果一个参数的值有多个,可以将它们放在不同的行中,只需要在其后的每个行前多置一个空格即可;postfix会把第一个字符为空格或tab的文本行视为上一行的延续;

启动postfix
/usr/local/postfix/sbin/postfix  start

连接postfix,验正服务启动状况:
# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 mail.benet.org ESMTP Postfix

"/var/spool/mail/redhat": 1 message 1 new
>N  1 root@benet.org        Wed Sep  5 10:59  15/488   "Mail test!"
&

八、为postfix开启基于cyrus-sasl的认证功能

使用以下命令验正postfix是否支持cyrus风格的sasl认证,如果您的输出为以下结果,则是支持的:
# /usr/local/postfix/sbin/postconf  -a
cyrus
dovecot

#vi /etc/postfix/main.cf
添加以下内容:
############################CYRUS-SASL############################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination
smtpd_sasl_auth_enable = yes
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!

#vi /usr/local/lib/sasl2/smtpd.conf
添加如下内容:
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN

让postfix重新加载配置文件
#/usr/local/postfix/sbin/postfix reload

# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 Welcome to our mail.benet.org ESMTP,Warning: Version not Available!
ehlo mail.benet.org
250-mail.benet.org
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN               (请确保您的输出以类似两行)
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

九、让postfix支持虚拟域和虚拟用户

1、编辑/etc/postfix/main.cf,添加如下内容:
########################Virtual Mailbox Settings########################
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/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 Settings########################
message_size_limit = 14336000
virtual_mailbox_limit = 20971520
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = mysql:/etc/postfix/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

2、添加为支持虚拟域和虚拟用户所用到的配置文件

编辑/etc/postfix/mysql_virtual_alias_maps.cf ,添加如下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address

编辑/etc/postfix/mysql_virtual_domains_maps.cf ,添加如下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain

编辑/etc/postfix/mysql_virtual_mailbox_limit_maps.cf ,添加如下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username

编辑/etc/postfix/mysql_virtual_mailbox_maps.cf ,添加如下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username

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/var/mailbox,你可以指定为别的目录,比如常见到的/var/spool/mail,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
    --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

# 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('/var/mailbox/',maildir)
MYSQL_NAME_FIELD  name
MYSQL_MAILDIR_FIELD  concat('/var/mailbox/',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

# 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

# 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 /var/mailbox
#chown –R postfix /var/mailbox

#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

十二、安装Extmail-1.0.2

1、安装
# tar zxvf extmail-1.0.2.tar.gz
# mkdir -pv /var/www/extsuite
# mv extmail-1.0.2 /var/www/extsuite/extmail
# cp /var/www/extsuite/extmail/webmail.cf.default  /var/www/extsuite/extmail/webmail.cf

2、修改主配置文件
#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 = postfix
SYS_MYSQL_PASS = 123456

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

3、apache相关配置

由于extmail要进行本地邮件的投递操作,故必须将运行apache服务器用户的身份修改为您的邮件投递代理的用户;本例中打开了apache服务器的 suexec功能,故使用以下方法来实现虚拟主机运行身份的指定。此例中的MDA为postfix自带,因此将指定为postfix用户:
<VirtualHost *:80>
ServerName mail.benet.org
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
SuexecUserGroup postfix postfix
</VirtualHost>

修改 cgi执行文件属主为apache运行身份用户:
# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

如果您没有打开apache服务器的suexec功能,也可以使用以下方法解决:
# vi /etc/httpd/httpd.conf
User postfix
Group postfix

<VirtualHost *:80>
ServerName mail.benet.org
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
</VirtualHost>

4、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。
# tar zxvf Unix-Syslog-0.100.tar.gz
# cd Unix-Syslog-0.100
# perl Makefile.PL
# make
# 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:
# tar zxvf DBD-mysql-3.0002_4.tar.gz  
# cd cd 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)
# make
# make install

十三、安装Extman-0.2.2

1、安装及基本配置

#tar zxvf  extman-0.2.2.tar.gz
# mv extman-0.2.2 /var/www/extsuite/extman

修改配置文件以符合本例的需要:
# 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:

# cd /var/www/extsuite/extman/docs
# mysql -u root -p <extmail.sql
# mysql -u root -p <init.sql

修改cgi目录的属主:
# 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:
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';

在apache的主配置文件中Extmail的虚拟主机部分,添加如下两行:
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html

创建其运行时所需的临时目录,并修改其相应的权限:
#mkdir  -pv  /tmp/extman
#chown postfix.postfix  /tmp/extman

好了,到此为止,重新启动apache服务器后,您的Webmail和Extman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,如下:
http://mail.benet.org

选择管理即可登入extman进行后台管理了。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,您需要安装此些模块才可能正常显示图形日志。
