一、简介：
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

安装环境：
centos 5.2
域名机器名：mail.chinastor.cn
域名：chinastor.cn
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 /tmp/mysql.sock
MYSQL_OPT 0
MYSQL_DATABASE extmail

[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
