centos 5.2系统上安装配置postfix邮件服务器安装部署操作记录:

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

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.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

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

7、安装cyrus-sasl

[root@localhost ~]# rpm -ivh cyrus-sasl-2.1.22-8.fc8.src.rpm 

[root@localhost ~]# cd $SPEC

编辑cyrus-sasl.spec 将下面:

# Bundling copy of Berkeley DB, for sasldb support.

topdir=`pwd`

pushd db-%{db_version}/build_unix

../dist/configure /

        --with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic /

        --with-uniquename=_cyrus_sasl_sasldb_rh /

        --prefix=${topdir}/db-instroot /

        --includedir=${topdir}/db-instroot/include /

        --libdir=${topdir}/db-instroot/lib

改为:

# Bundling copy of Berkeley DB, for sasldb support.

topdir=`pwd`

pushd db-%{db_version}/build_unix

../dist/configure /

        --with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic /

        --with-uniquename=_cyrus_sasl_sasldb_rh /

        --prefix=${topdir}/db-instroot /

        --includedir=${topdir}/db-instroot/include /

        --libdir=${topdir}/db-instroot/lib /

        --with-authdaemond=/var/spool/authdaemon

B、生成rpm

[root@localhost SPECS]# rpmbuild -bb cyrus-sasl.spec 

[root@localhost RPMS]# cd $RPMS/i386

[root@localhost i386]# rpm -e --nodeps cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib (如果这些包存在)

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

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 =
