系统逻辑结构

前提：开始前请确保您已经配置好指向此邮件服务器MX记录及其它DNS设置；本示例中的域名为gdc8888.com，邮件服务器FQDN为mail.gdc8888.com，IP地址为192.168.1.11；同时，如果您的服务器事先已经安装了sendmail，请卸载之；

一、安装mysql-5.0.45

# rpm -qa |grep mysql|xargs rpm -e --nodeps(删除系统自带的mysql)

# 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 &

# netstat -tnl(查看有没有打开3306端口)

# cd /root/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 -u root password '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

四、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 --with-suexec-caller=daemon --with-suexec-docroot=/var/www

# make

# make install

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

五、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：

DirectoryIndexindex.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

修改为：

找到

修改为:注意把#去掉

说明:这个对本文来说并非是不可少的。

# mkdir /var/www

# /usr/local/apache/bin/apachectl start启动apache服务

六、安装Courier authentication library

1.先添加vuser用户和vgroup组

# groupadd -g 1000 vgroup

# useradd -g 1000 -u 1000 -M -s /bin/false vuser

# tar jxvf courier-authlib-0.58.tar.bz2

# cd courier-authlib-0.58

#./configure --prefix=/usr/local/courier-authlib --without-stdheaderdir --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-mailuser=vuser --with-mailgroup=vgroup --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"

# make

# make install

# make install-migrate

# make install-configure

# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon(这一步需注意，这一步若没有，则会出现authdaemon权限拒绝。)

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

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

修改/etc/authdaemonrc文件

authmodulelist="authmysql"

authmodulelistorig="authmysql"

daemons=10

DEBUG_LOGIN=2

编辑/etc/authmysqlrc为以下内容，其中1000,1000为vuser用户的UID和vgroup的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_USERNAMEextmail(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_DATABASEextmail

MYSQL_USER_TABLEmailbox

MYSQL_CRYPT_PWFIELDpassword

MYSQL_UID_FIELD '1000'

MYSQL_GID_FIELD'1000'

MYSQL_LOGIN_FIELDusername

MYSQL_HOME_FIELDconcat('/var/mailbox/',homedir)

MYSQL_NAME_FIELDname

MYSQL_MAILDIR_FIELDconcat('/var/mailbox/',maildir)

MYSQL_QUOTA_FIELDquota

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

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

# chkconfig --add courier-authlib

# chkconfig courier-authlib on

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

# ldconfig

# ldconfig -v

# service courier-authlib start(启动服务)

七、安装Courier-IMAP

# tar jxvf courier-imap-4.1.0.tar.bz2
