一、简介:


本文以最简单,最方便的方法在centos 5.2 上安装一个全功能的邮件系统,此文适合REDHAT所有系列,在文中,能用RPM 安装的,我们将采用rpm 安装,如果rpm没有的,我们将创建自己的rpm。 部分软件简介:
1、AMP ---apache(web服务) 、mysql(数据库)、php(非必需) 的简称
2、postfix --mta 邮件系统核心
3、courier-authlib--一个为courier-imap,maildrop,sasl2 提供用户信息的后台进程序
4、courier-imap --提供pop3,pop3s,imap,imaps 服务的程序
5、amavisd-new --提供内容过滤
6、clamav -- 著名的杀毒软件
7、extmail --一个著名的webmail程序
8、extman --与extmail集成的后台管理程序
9、slockd --一个基于smtp阶段的反垃圾邮件程序
10、vhmgr --由本文作者编写,用于管理apache,ftp,mysql 的虚拟主机管理程序。

安装环境:
centos 5.2
域名机器名:mail.yiyou.org
域名:yiyou.org

二、安装系统

安装系统时,选择“customize software selection”(自定义安装),在package group selection 对话框里选择:
[*]base
[*]devlopment libraries
[*]development tools
[*]editors
[*]text-base internet
其它不选择。
在setup agnet(或进入系统后运行setup) 里选择firewall configuration 将security level 与SELinux 改为disabled,目的是为了避免在安装调试时产生不必要的麻烦,在系统安装完成后,可以自己去调试安全部分,在这里将不作详细介绍。
配置yum,在本文中使用的是网通线路,所以选择了http://mirrors.ta139.com/ 作为安装镜像。
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# wget http://mirrors.ta139.com/CentOS-Base.repo.ta139
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@localhost yum.repos.d]# mv CentOS-Base.repo.ta139 CentOS-Base.repo

三、安装软件


1、安装AMP


 [root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql
修改启动配置并启动
[root@localhost ~]# chkconfig --level 345  mysqld on
[root@localhost ~]# chkconfig --level 345  httpd on 
[root@localhost ~]# service mysqld start
[root@localhost ~]# service httpd start

2、安装phpmyadmin

注意:可以选择自己需要的版本
[root@localhost ~]# wget http://nchc.dl.sourceforge.net/sourceforge/phpmyadmin/phpMyAdmin-2.11.9-all-languages-utf-8-only.tar.bz2
[root@localhost ~]# tar xjf phpMyAdmin-2.11.9-all-languages-utf-8-only.tar.bz2 
[root@localhost ~]# mv phpMyAdmin-2.11.9-all-languages-utf-8-only /var/www/html/phpmyadmin
[root@localhost phpmyadmin]# cp config.sample.inc.php config.inc.php 
编辑config.inc.php 改为下面,字符串是任意的。
$cfg['blowfish_secret'] = 'skssiwksksie'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
进入phpmyadmin 请马上修改mysql root 用户的密码。

3、导入extman 后台数据库

将extmail/extman/slockd 上传到服务器,可以使用ftp/winscp 上传
[root@localhost ~]# tar zxf extman-0.2.5b1.tar.gz 
[root@localhost ~]# cd extman-0.2.5b1/docs/
[root@localhost docs]# mysql -uroot -p <extmail.sql 
Enter password: 
[root@localhost docs]# mysql -uroot -p <init.sql 
Enter password: 
如何使用了phpmyadmin改了root 密码,记得输入密码,如果密码为空,请按回车。

4、RPM 简介

下面我们将采用rpm 的方式安装软件
/usr/src/redhat/SPEC spec 文件夹,通常是rpm文件夹
/usr/src/redhat/RPMS 是生成rpm 的文件,下面还有i368,i486 等子文件夹,一般我们用i386 架构
/usr/src/redhat/SOURCE 源文件文件夹
为了安装时切换目录的方便,我们将目录存放到一个shell变量里。
[root@localhost ~]# export RPMS=/usr/src/redhat/RPMS
[root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES
[root@localhost ~]# export SPEC=/usr/src/redhat/SPECS
在下面安装过程中,大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的,只是shell变量的替换。

5、安装authlib

A、安装依懒的包

[root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.61.0.tar.bz2
[root@localhost ~]# tar xjf courier-authlib-0.61.0.tar.bz2 
[root@localhost ~]# cd courier-authlib-0.61.0
[root@localhost courier-authlib-0.61.0]# cp courier-authlib.spec $SPEC
[root@localhost courier-authlib-0.61.0]# cd ..
[root@localhost ~]# cp courier-authlib-0.61.0.tar.bz2 $SOURCE
[root@localhost ~]# cd $SPEC
[root@localhost SPECS]# rpmbuild -bb courier-authlib.spec (创建rpm文件)

B、安装生成的rpm

[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh courier-authlib-0.61.0-1.i386.rpm 
[root@localhost i386]# rpm -ivh courier-authlib-devel-0.61.0-1.i386.rpm 
[root@localhost i386]# rpm -ivh courier-authlib-mysql-0.61.0-1.i386.rpm 

C、配置authlibdaemon

[root@localhost i386]# cd /etc/authlib/
[root@localhost authlib]# mv authdaemonrc authdaemonrc.bak
[root@localhost authlib]# vim authdaemonrc
输入下面的内容:
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
authdaemonvar=/var/spool/authdaemon
DEBUG_LOGIN=2
DEFAULTOPTIONS="wbnodsn=1"
LOGGEROPTS=""
D、配置authmysqlrc
[root@localhost authlib]# mv authmysqlrc authmysqlrc.bak
[root@localhost authlib]# vim authmysqlrc
输入下面的内容:
MYSQL_SERVER    localhost
MYSQL_USERNAME  extmail
MYSQL_PASSWORD  extmail
MYSQL_PORT      0
MYSQL_SOCKET    /var/lib/mysql/mysql.sock
MYSQL_OPT       0
MYSQL_DATABASE  extmail

MYSQL_SELECT_CLAUSE     SELECT username,password,"",uidnumber,gidnumber,\
                        CONCAT('/home/data/domains/',homedir),               \
                        CONCAT('/home/data/domains/',maildir),               \
                        quota,                                          \
                        name                                            \
                        FROM mailbox                                    \
                        WHERE username = '$(local_part)@$(domain)' 


E、启动authlib

[root@localhost ~]# service courier-authlib start
Starting Courier authentication services: authdaemond
[root@localhost ~]# chmod 777 /var/spool/authdaemon/

6、安装courier-imap

由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户,并创建一个rpm环境
[root@localhost ~]# useradd yiyou
软件包依懒需要安装openldap-server,rpm创建完成后可以删除
[root@localhost ~]# yum -y install openldap-servers
[root@localhost ~]# su - yiyou
[yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
[yiyou@localhost ~]$ vim  ~/.rpmmacros
输入内容:
%_topdir /home/yiyou/rpm
[yiyou@localhost ~]$ wget http://prdownloads.sourceforge.net/courier/courier-imap-4.4.1.tar.bz2
[yiyou@localhost ~]$ cp courier-imap-4.4.1.tar.bz2 rpm/SOURCES/
[yiyou@localhost ~]$ tar xjf courier-imap-4.4.1.tar.bz2 
[yiyou@localhost ~]$ cd courier-imap-4.4.1
[yiyou@localhost courier-imap-4.4.1]$ cp courier-imap.spec ../rpm/SPECS/
[yiyou@localhost courier-imap-4.4.1]$ cd ../rpm/SPECS/
编辑courier-imap.spec 将下面的内容:
%if %suse_version
BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)
%else
BuildPreReq: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers
%endif
改为:
%if %suse_version
BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel 
%else
BuildPreReq: rpm >= 4.0.2 sed openldap-devel openldap-servers
%endif
创建rpm
[yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec 
完成rpm后,输入exit退出当前用户。
[root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.4.1-1.i386.rpm 
[root@localhost ~]# service courier-imap start

 reject_invalid_hostname
复制extman/docs 目录的cf 文件到/etc/postfix
[root@localhost postfix]# cp /root/extman-0.2.5b1/docs/mysql_virtual_* .
因为配置文件的用户、密码与数据库时一样,所以不用修改。
[root@localhost postfix]# service postfix start

9、安装maildrop

A、下载生成RPM

[root@localhost postfix]# cd
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/maildrop-2.0.4.tar.bz2
[root@localhost ~]# cp maildrop-2.0.4.tar.bz2 $SOURCE

在/etc/postfix/main.cf 加入下面的内容
content_filter = smtp-amavis:[localhost]:10024
[root@localhost ~]# service postfix reload

11、安装extman/extmail

A、配置apache

修改/etc/httpd/conf/httpd.conf,将下面的选项改为:
User vuser
Group vgroup
[root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim extmail.conf
输入下面的内容:
Alias /extman/cgi/ /var/www/extsuite/extman/cgi/
Alias /extman /var/www/extsuite/extman/html/


<Location "/extman/cgi">
SetHandler cgi-script
Options +ExecCGI
</Location>

# config for ExtMail
Alias /extmail/cgi/ /var/www/extsuite/extmail/cgi/
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extmail参数

[root@localhost ~]# cd /var/www/extsuite/extmail/
[root@localhost extmail]# cp webmail.cf.default webmail.cf
修改webmail.cf 下面的选项
SYS_SESS_DIR = /tmp/extmail
SYS_MAILDIR_BASE = /home/data/domains
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail

C、配置extman参数

[root@localhost extmail]# cd /var/www/extsuite/extman/
修改webman.cf 下面的选项:
SYS_MAILDIR_BASE = /home/data/domains

D、创建session 目录

[root@localhost extman]# mkdir /tmp/{extman,extmail}
[root@localhost extman]# chown vuser:vgroup /tmp/ext*

E、配置后台日志分析工具

[root@localhost addon]# cd /var/www/extsuite/extman/addon/
[root@localhost addon]# cp -r mailgraph_ext /usr/local/
将下面的内容加入/etc/rc.local
/usr/local/mailgraph_ext/mailgraph-init start
/usr/local/mailgraph_ext/qmonitor-init start
安装所依懒的软件包
[root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail

F、启动后台进程

[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、访问extmail/extman

打开浏览器,输入http://your_ip_address/extmail 注意:your_ip_address 为你实际的ip
第一个测试用户为:postmaster 密码:extmail 域:extmail

打开浏览器,输入http://your_ip_address/extman
extman root 用户为:root@extmail.org 密码为:extmail*123*
注意:进入系统后要修改密码及找回密码的提示问题、答案。

12、安装slockd

slockd 是一个基于策略的垃圾邮件软件,很多用户反映使用后,反垃圾效果非常明显,但是有部分用户由于对该软件的使用,特性不了解,而产生了很多麻烦。
所在在此建议,如果你对该软件不了解,或者系统里的垃圾邮件少,可以暂时不安装。
[root@localhost ~]# tar zxf slockd-0.2beta1.tar.gz 
[root@localhost ~]# cp -r slockd-0.2beta1 /usr/local/slockd
[root@localhost ~]# cd /usr/local/slockd
将下面的内容加入/etc/rc.local
/usr/local/slockd/slockd-init start
[root@localhost slockd]# vim config/main.cf (编辑slockd/config/main.cf)修改下面的内容
setsid          1  (去掉注释,让程序成为后台进程)
修改/etc/postfix/main.cf 将原先的内容:
smtpd_recipient_restrictions =
 permit_mynetworks,
 permit_sasl_authenticated,
 reject_unauth_destination,
 reject_unauth_pipelining,
 reject_invalid_hostname
改为:
smtpd_recipient_restrictions =
 permit_mynetworks,
 permit_sasl_authenticated,
 reject_unauth_destination,
 reject_unauth_pipelining,
 reject_invalid_hostname,
 check_policy_service inet:127.0.0.1:10030
重载postfix 配置文件
[root@localhost slockd]# service postfix reload

13、安装vhmgr

vhostmgr 是一款虚似主机管理软件,可以对apache,pure-ftp,mysql 进行管理,是管理员的好帮手。
vhostmgr 有如下特点:
a、只需要安装一个apache,ftp
b、apache 不需要以root 运行。用普通用户身份运行就行了。
c、可以通过web 进行重读配置文件,系统关机,等操作
d、采用apache+cgi 方式运行,容易配置,安装、使用文档详细。
e、如果你是一个管理员,每为一个用户添加主机而麻烦,使用该软件将为你节省大量时间。
f、开通apache,ftp,mysql 都是即时生效。
更多功能,更多方便,使用后才知道!!!
g、支持freebsd ,linux 等多种系统

vhmgr 还有一个重要特点:开源并完全免费使用。

为了不重复劳功,将不再次叙述。

apache 改变运行id 后,php session功能将会出现问题,因为session 的存储目录权限没有跟着改变为新的,只要执行下面的命令即可解决问题。
[root@localhost slockd]# chown -R vuser:vgroup /var/lib/php/session/
