企业网extmail服务器搭建

Mail服务器（Postfix+Dovecot+Extmail+Extman基于虚拟账号）

实验拓扑

LAMP（Linux+Apache+MySQL+PHP）环境搭建

首先需要搭建LAMP环境

安装Apache

[[email protected] apr-1.4.6]# tar -zxvf apr-util-1.5.1.tar.gz -C /usr/local/src/

[[email protected] apr-1.4.6]# cd /usr/local/src/apr-1.4.6/

[[email protected] apr-1.4.6]# ./configure --prefix=/usr/local/apr

[[email protected] apr-1.4.6]# make

[[email protected] apr-1.4.6]# make install

[[email protected] src]# cd apr-util-1.5.1/

[[email protected] apr-util-1.5.1]# ./configure --with-apr=/usr/local/apr/bin/apr-1-config

[[email protected] apr-util-1.5.1]# make

[[email protected] apr-util-1.5.1]# make install

[[email protected] cdrom]# cd /mnt/cdrom/Server/

[[email protected] Server]# rpm -ivh /mnt/cdrom/Server/pcre-devel-6.6-2.el5_1.7.i386.rpm

安装http

[[email protected] ~]# tar -jxvf httpd-2.4.4.tar.bz2 -C /usr/local/src/

[[email protected] ~]# cd /usr/local/src/httpd-2.4.4/

[[email protected] httpd-2.4.4]# ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-ssl --enable-rewrite --with-apr=/usr/local/apr/bin/apr-1-config --with-apr-util=/usr/local/apr/bin/apu-1-config --with-pcre -with-z --enable-mpms-shared=all

[[email protected] httpd-2.4.4]# make

[[email protected] httpd-2.4.4]# make install

[[email protected] ~]# cd /etc/init.d/

[[email protected] init.d]# chmod a+x httpd

[[email protected]l init.d]# ln -s /usr/local/apache/include/ /usr/include/apche

[[email protected] init.d]# vim /etc/man.config

安装mysql

[[email protected] ~]# groupadd mysql

[[email protected] ~]# useradd -r -g mysql mysql

[[email protected] src]# cd /usr/local/

[[email protected] local]# ln -s /usr/local/src/mysql-5.5.15-linux2.6-i686/ mysql

[[email protected] mysql]# chown -R mysql .

[[email protected] mysql]# chgrp -R mysql .

[[email protected] mysql]# scripts/mysql_install_db --user=mysql

[[email protected] mysql]# chown -R root .

[[email protected] mysql]# chown -R mysql data

[[email protected] mysql]# cp support-files/my-medium.cnf /etc/my.cnf

[[email protected] mysql]# cp support-files/mysql.server /etc/init.d/mysqld

[[email protected] mysql]# service mysqld start

Starting MySQL..... [ OK ]

[[email protected] mysql]# chkconfig --add mysqld

配置mysql环境变量

[[email protected] mysql]# vim /etc/profile

[[email protected] mysql]# . /etc/profile

创建mysql.conf文件并添加库文件路径

[[email protected] mysql]# vim /etc/ld.so.conf.d/mysql.conf

/usr/local/mysql/lib

[[email protected] mysql]# ldconfig

处理头文件

[[email protected] mysql]# ln -s include /usr/include/mysql

给mysql数据库添加密码

安装php

[[email protected] php-5.4.13]# tar -jxvf php-5.4.13.tar.bz2 -C /usr/local/src/

[[email protected] php-5.4.13]# ./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 --enable-mbstring --enable-xml --with-png-dir --with-png --with-jpeg-dir --with-zlib --enable-mbstring --with-freetype-dir

[[email protected] php]# make

[[email protected] php]# make install

编辑/etc/profile

库文件处理

[[email protected] php]# ldconfig

处理头文件

[[email protected] php]# ln -s /usr/local/php/include/ /usr/include/php

编辑apache的配置文件支持php模块

下面进行exymail的搭建

本次主要来搭建北京地区extmail

关闭开发平台的sendmail功能，因为要搭建extmail。

更改主机名和dns指向

关闭sendmail并设为开机关闭

上传搭建extmail所需要的软件包

postfix-2.8.2.tar.gz

courier-authlib-0.63.0.tar.bz2

Unix-Syslog-0.100.tar.gz

extmail-1.2.tar.gz

extman-1.1.tar.gz

打开saslauth服务设为开机启动

安装其他软件包

Yum install mysql-devel

安装postfix

[[email protected] ~]# tar -zxvf postfix-2.8.2.tar.gz -C /usr/local/src/

[[email protected] ~]# cd /usr/local/src/postfix-2.8.2/

[[email protected] postfix-2.8.2]# group -g 2525 postfix

-bash: group: command not found

[[email protected] postfix-2.8.2]# groupadd -g 2525 postfix

[[email protected] postfix-2.8.2]# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

[[email protected] postfix-2.8.2]# groupadd -g 2526 postdrop

[[email protected] postfix-2.8.2]# useradd -g postdrop -u 2526 -s /bin/false -M postdro

Mysql的路径一定要正确

[[email protected] postfix-2.8.2]# make && make install

install_root: [/] /

tempdir: [/usr/local/src/ postfix-2.6.5] /tmp

config_directory: [/etc/postfix]

daemon_directory: [/usr/libexec/postfix]

command_directory: [/usr/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]

readme_directory: [no]

执行/usr/bin/newaliases生成新的别名文件，提高postfix的效率

[[email protected] postfix-2.8.2]# /usr/bin/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

为了管理postfix服务的启动关闭，创建脚本，复制postfix的rpm包的控制脚本

[[email protected] ~]# cd /tmp/

[[email protected] tmp]# mkdir abc

[[email protected] tmp]# cd abc/

[[email protected] abc]# cp /mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm ./

[[email protected] abc]# rpm2cpio postfix-2.3.3-2.1.el5_2.i386.rpm |cpio -id

编辑postfix配置文件

[[email protected] init.d]# vim /etc/postfix/main.cf

配置邮件服务器的中继

发送邮件测试

为postfix开启基于rycus-sasl认证功能.

vim /etc/postfix/main.cf

添加认证功能

四、安装Courier authentication library

[[email protected] ~]# tar jxvf courier-authlib-0.63.0.tar.bz2 -C /usr/local/src/

[[email protected] ~]# cd /usr/local/src/courier-authlib-0.63.0/

[[email protected] courier-authlib-0.63.0]# ./configure \

> --prefix=/usr/local/courier-authlib \

> --sysconfdir=/etc \

> --with-authmysql \

> --with-mysql-libs=/usr/local/mysql/lib \

> --with-mysql-includes=/usr/local/mysql/include \

> --with-redhat \

> --with-authmysqlrc=/etc/authmysqlrc \

> --with-authdaemonrc=/etc/authdaemonrc \

> --with-ltdl-lib=/usr/lib \

> --with-ltdl-include=/usr/include

[[email protected] courier-authlib-0.63.0]# make

[[email protected] courier-authlib-0.63.0]# make install

[[email protected] courier-authlib-0.63.0]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon

[[email protected] courier-authlib-0.63.0]# cp /etc/authdaemonrc.dist /etc/authdaemonrc

[[email protected] courier-authlib-0.63.0]# cp /etc/authmysqlrc.dist /etc/authmysqlrc

[[email protected] etc]# vim /etc/authdaemonrc

[[email protected] etc]# vim /etc/authmysqlrc

[[email protected] etc]# cd /usr/local/src/courier-authlib-0.63.0/

[[email protected] courier-authlib-0.63.0]# cp courier-authlib.sysvinit /etc/init.d

# 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.d/courier-authlib.conf

# ldconfig -v

启动服务

[[email protected] etc]# service courier-authlib start

Starting Courier authentication services: authdaemond

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

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

五、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：

2、使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：

[[email protected] ~]# tar -zxvf extman-1.1.tar.gz

[[email protected] ~]# mv extman-1.1 /var/www/extsuite/extman

由于mysql版本的原因。导入数据库之前我们需要对extmail.sql进行更改，extmail.sql中所包含的的text的行把后面的default ‘ ’删掉，把TYPE=MyISAMCOMMENT=’ExtMail - Virtual Mailboxes‘行删除，把87行改成can_signup varchar(255).
