HREL5.0+LAMP+postfix+mysql+postfixadmin+dovecot

                                  本文是在RHEL5.0上完成的实验
  在查看了众多文章后,自己的邮件系统终于出炉呢..一路艰辛的走过，再次原与大家分享一下安装经验

准备工作，
# service iptables stop
确保/etc/sysconfig/saslauthd 中 MECH = shadow
确保/etc/sysconfig/selinux 中 SELINUX=disabled

-1.安装LAMP环境

LAMP就是Linux+Apache+MySql+PHP搭建的动态网站环境，是目前互联网上非常流行的一个网页服务组合。
网上有很多教程搭建LAMP环境，基本上都是编译安装的，其实对新手来说只需要了解LAMP环境的一些特性，RMP安装相对来说容易上手点，只需要安装几个光盘上的安装包就可以顺利完成LAMP的搭建。
安装Apache

初始化MySql数据库

    [root@linux-a ~]# mysql_install_db
    Installing all prepared tables
    Fill help tables
    To start mysqld at boot time you have to copy support-files/mysql.server
    to the right place for your system
    PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
    To do so, start the server, then issue the following commands:
    /usr/bin/mysqladmin -u root password 'new-password'
    /usr/bin/mysqladmin -u root -h linux-a.test.com password 'new-password'
    See the manual for more instructions.
    You can start the MySQL daemon with:
    cd /usr ; /usr/bin/mysqld_safe &
    You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:
    cd sql-bench ; perl run-all-tests
    Please report any problems with the /usr/bin/mysqlbug script!
    The latest information about MySQL is available on the web at
    http://www.mysql.com
    Support MySQL by buying support/licenses at http://shop.mysql.com

测试配置：



安装好上面之后还需要安装以下rpm包

php-mbstring-5.1.6-20.e15.i386.rpm
和
php-imap-5.16-20.e15.i386.rpm
libc-client-2004g-2.2.1.i386.rpm
安装好后 重新启动apache




-2.在Linux上使用Postfix+dovecot+MySQL+PostfixAdmin实现基本的邮件服务


2.1. 配置MySQL
添加Postfix数据库
mysql> CREATE DATABASE postfix;
mysql> GRANT ALL PRIVILEGES ON postfix.* TO 'postfix'@'localhost' IDENTIFIED BY 'postfix';
 
2.2 安装配置PostfixAdmin
到http://sourceforge.net/projects/postfixadmin/下载最新的软件包。
# tar -zxvf postfixadmin-2.2.1.1.tar.gz
# mv postfixadmin-2.2.1.1 /var/www/postfixadmin
# cd /var/www/postfixadmin
# vim config.inc.php
修改下面相应的参数
$CONF['configured'] = true;
$CONF['default_language'] = 'cn';
$CONF['postfix_admin_url'] = '/postfixadmin';
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = ‘postfix';
$CONF['database_name'] = 'postfix';
$CONF['domain_path'] = 'YES';
$CONF['domain_in_mailbox'] = 'NO';
$CONF['encrypt'] = 'md5crypt';
$CONF['emailcheck_resolve_domain] = 'NO';
 

重新启动apache

访问PostfixAdmin的设置页http://IP or domain/postfixadmin/setup.php

出现postfixadmin的输入框
创建Setup password(如：123456)
点击“Generate password hash”获取一段加密代码
将该代码拷贝到配置文件config.inc.php中的以下配置中
$CONF['setup_password'] = 'change';（用加密代码替换change）
然后再次访问PostfixAdmin的设置页，创建管理员的账号和密码
（需要正确输入之前创建的Setup password才能创建管理员账号）
访问PostfixAdmin的登录页http://IP or domain>/postfixadmin/
使用管理员账号登录后，就可以进行相应的管理工作。
创建之后移动setup.php.bak
mv /var/www/html/postfixadmin/setup.php /var/www/html/postfixadmin/setup.php.bak


2.3. 安装配置Postfix
Postfix的大部分RPM包都没有mysql的支持,还好我找到了带有mysql和sasl支持的RPM包。
软件包下载地址：http://www.linuxmail.info/postfix-rpm-packages/
如果你无法下载的话，就只能自己编译安装了。
 
停止系统中默认的sendmail服务
# service sendmail stop
# chkconfig sendmail off
# mv /usr/bin/newaliases /usr/bin/newaliases.bak
# mv /usr/bin/mailq /usr/bin/mailq.bak
# mv /usr/sbin/sendmail /usr/sbin/sendmail.bak
 
安装Postfix
# rpm -ivh postfix-2.5.1-1.mysql.sasl2.vda.rhel5.i386.rpm
给postfix原主配文件改名
#mv /etc/postfix/main.cf /etc/postfix/main.cf.bak
配置Postfix
# vim /etc/postfix/main.cf
#=====================BASE=========================

启动Postfix
# service postfix start
 
系统启动时自动启动Postfix服务
# chkconfig postfix on
 
刷新Postfix的配置文件
# postfix reload
 
查看Postfix的当前配置信息
# postconf -n
 
查看Postfix的默认配置信息
# postconf -d

2.4. 安装dovecot用来imap和pop3服务验证
首先安装pam-devel
否则（启动dovecot时出现Auth process died too early）
和mysql_devel的rpm包
否则(编译安装时dovecot出现
configure: error: can't build with Mysql support: libmysqlclient not found)


再安装配置dovecot
如果系统中默认安装了dovecot，那么要先把它卸载或停用。
# service dovecot stop
# chkconfig dovecot off
 
编译安装
下载dovecot的源码包（http://www.dovecot.org/download.html）
# tar zxvf dovecot-1.2.8.tar.gz
# cd dovecot-1.0.rc14
# ./configure --prefix=/usr/local/dovecot --sysconfdir=/usr/local/etc --with-mysql --without-ssl --disable-ipv6
# make
# make install

 
建立启动进程所依赖的用户
# useradd -d /dev/null dovecot -s /bin/false
 
修改配置文件
拴出dovecot.conf的主配置文件
#mv /usr/local/etc/dovecot.conf /usr/local/etc/dovecot.conf.bak

# vim /usr/local/etc/dovecot.conf
base_dir = /var/run/dovecot
protocols = imap imaps pop3 pop3s
listen = *
disable_plaintext_auth = no
shutdown_clients = yes
log_path = /var/log/dovecot.log
ssl = no
mail_location = maildir:/var/spool/mail/%d/%n
auth default {                                    #注意空格
  mechanisms = plain login cram-md5
  passdb sql {
    args = /usr/local/etc/dovecot-mysql.conf
  }
 
  userdb sql {
    args = /usr/local/etc/dovecot-mysql.conf
  }
 
  socket listen {
    client {
        path = /var/spool/postfix/private/auth    #这里要和postfix配置文件的配置相对应
        mode = 0660
        user = postfix
        group = postfix
    }
  }
}
first_valid_uid = 100

dovecot的mysql配置文件
# vim /usr/local/etc/dovecot-mysql.conf
driver = mysql
connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=postfix

default_pass_scheme = MD5-CRYPT
password_query = SELECT password FROM mailbox WHERE username = '%u'
user_query = SELECT maildir,100 AS uid,102 AS gid FROM mailbox WHERE username = '%u'


修改/var/spool/mail文件的写入属性(否则dovecot会启动不了)
#chmod o+w /var/spool/mail

启动dovecot
# /usr/local/dovecot/sbin/dovecot
 
可以把启动命令写进/etc/rc.d/rc.local文件，以使系统启动时能够自动启动dovecot服务。
# echo "/usr/local/dovecot/sbin/dovecot" >> /etc/rc.d/rc.local
 
停止dovecot
只能用kill命令来停止dovecot服务
# ps -aux | grep dovecot
# kill <"/usr/local/dovecot/sbin/dovecot"的pid>
 
-3. 验证

POP3验证
[root@game222 ~]# telnet 10.0.0.2 110
Trying 10.0.0.2...
Connected to game222.test.com (10.0.0.2).
Escape character is '^]'.
+OK Dovecot ready.


 
IMAP验证
[root@game222 ~]# telnet 10.0.0.2 143
Trying 10.0.0.2...
Connected to game222.test.com (10.0.0.2).
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot ready.

 

测试POP3接收邮件
(使用postfixadmin建立的用户)

[root@mail ~]# telnet 10.0.0.2 110
Trying 127.0.0.1…
Connected to localhost.localdomain (127.0.0.1).
Escape character is ‘^]’.
+OK Dovecot ready.
user [email protected]  //使用邮件用户“userd”登录
+OK
pass aaa           //输入userd的密码userd
+OK Logged in.
List               //查看邮件列表
+OK 1 messages:
1 485
.
retr 1             //收取并查看第一封邮件内容，一下内容就不显示了
quit
+OK Logging out.
Connection closed by foreign host.




客户端可以使用squirrelmail作为IMAP客户端，OE可以使用pop3的客户端
安装直接使用rpm包安装squirrelmail（系统包里自带）
安装好后
修改/etc/squirrelmail/config.php
$squirrelmail_default_language = 'zh_CN'




如果出现问题多查看apache,dovecot,postfix的日志记录
上述日志文件分别为
/var/log/httpd/error_log
/var/log/dovecot.log
/var/log/maillog
