特別值得一提的是CentOS extmail安裝與extman配置有很多值得學習的地方，這里我們主要介紹CentOS extmail安裝，包括介紹extman配置等方面。CentOS extmail安裝與extman配置。

A、CentOS extmail安裝配置apache
修改/etc/httpd/conf/httpd.conf，將下面的選項改為：
User vuser
Group vgroup
[root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim extmail.conf
輸入下面的內容：

Alias /extman /var/www/extsuite/extman/html/
<Location "/extman/cgi">
SetHandler cgi-script

Alias /extmail /var/www/extsuite/extmail/html/
<Location "/extmail/cgi">
SetHandler cgi-script
Options +ExecCGI
</Location>
[root@localhost ~]# mkdir /var/www/extsuite
[root@localhost ~]# tar zxf extmail-1.0.5b1.tar.gz
[root@localhost ~]# cp -r extmail-1.0.5b1 /var/www/extsuite/extmail
[root@localhost ~]# cp -r extman-0.2.5b1 /var/www/extsuite/extman

B、配置CentOS extmail安裝參數
[root@localhost ~]# cd /var/www/extsuite/extmail/
[root@localhost extmail]# cp webmail.cf.default webmail.cf
修改webmail.cf 下面的選項
SYS_SESS_DIR = /tmp/extmail
SYS_MAILDIR_BASE = /home/data/domains
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail

C、CentOS extmail安裝配置extman參數
[root@localhost extmail]# cd /var/www/extsuite/extman/
修改webman.cf 下面的選項：
SYS_MAILDIR_BASE = /home/data/domains

D、CentOS extmail安裝創(chuàng)建session 目錄
[root@localhost extman]# mkdir /tmp/{extman,extmail}
[root@localhost extman]# chown vuser:vgroup /tmp/ext*

E、CentOS extmail安裝配置后臺日志分析工具
[root@localhost addon]# cd /var/www/extsuite/extman/addon/
[root@localhost addon]# cp -r mailgraph_ext /usr/local/
將下面的內容加入/etc/rc.local
/usr/local/mailgraph_ext/mailgraph-init start
/usr/local/mailgraph_ext/qmonitor-init start
安裝所依懶的軟件包
[root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail

F、CentOS extmail安裝啟動后臺進程
[root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/qmonitor-init start
Starting queue statistics grapher: qmonitor
[root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start
Starting mail statistics grapher: mailgraph_ext

G、訪問CentOS extmail安裝與extman
打開瀏覽器，輸入http://your_ip_address/extmail 注意：your_ip_address 為你實際的ip
***個測試用戶為：postmaster 密碼：extmail 域：extmail
打開瀏覽器，輸入http://your_ip_address/extman
extman root 用戶為：root@extmail.org 密碼為：extmail*123*
注意：進入系統(tǒng)后要修改密碼及找回密碼的提示問題、答案。
