RHEL5+postfix+mysql+extmai（原始碼）（一）

配置一個postfix郵件系統，遠比我先前的想象複雜。這次共配置2個postfix系統，花了不少精力，其間也經歷不少麻煩，還好，最後都做成了！在配置過程中，參考了《postfix權威指南》和網上其他人寫的文章，但在實際的配置中，完全按照這些文件還是不易順利完成。現在此行文披露我做這個事情的全部過程，（在這還要多感謝老朱同志幫助經過我們半個月的努力才搞定的）希望對大家的工作有所幫助。還希望大家多多提寶貴意見！！

 *執行環境RHEL5

  本機IP為：172.16.17.86/16 自己為DNS伺服器 郵件伺服器為本機名稱為：mail.test.com

一、（1）配置rhel5的yum服務以方便安裝常用軟體

#service iptables stop

#chkconfig iptables off

#mkdir /media/cdrom

#mount /dev/cdrom /media/cdrom

#vim /etc/yum.repos.d/rhel-debuginfo.repo

修改為以下內容：

[rhel-debuginfo]

name=Red Hat Enterprise Linux $releasever – $basearch – Debug

baseurl=file:///media/cdrom/Server

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

（2）安裝開發工具

       #yum install gcc*

二、      安裝配置dns（bind）伺服器

#yum install bind caching-nameserver bind-chroot

#cp -a /etc/named.caching-nameserver.conf /etc/named.conf

# vim /etc/named.conf

直接分別執行下面兩個末行模式命令：

:%s/127.0.0.1/any/g

:%s/localhost/any/g

儲存退出

# vim /etc/named.rfc1912.zones

檔案末尾加入以下內容：

 

zone “test.com” IN {

        type master;

        file “test.com.zone”;

};

 

zone “16.172.in-addr.arpa” IN {

        type master;

        file “16.172”;

};

儲存退出

# cp -a /var/named/chroot/var/named/localhost.zone /var/named/chroot/var/named/test.com.zone

#vim /var/named/chroot/var/named/test.com.zone

刪除最下面兩行寫入下面兩行：

@                   IN MX 5        mail.test.com.

mail                IN A                     172.16.17.86

儲存退出

#cp -a /var/named/chroot/var/named/named.local /var/named/chroot/var/named/16.172

#vim /var/named/chroot/var/named/16.172

刪除最下面一行，寫入下面內容：

86.17   IN      PTR     mail.test.com.

儲存退出

#service named restart

#chkconfig named on

#echo `nameserver 172.16.17.86` > /etc/resolv.conf

驗證解析

# nslookup

> 172.16.17.86

Server:         172.16.17.86

Address:        172.16.17.86#53

86.17.16.172.in-addr.arpa       name = mail.test.com.

> mail.test.com

Server:         172.16.17.86

Address:        172.16.17.86#53

Name:   mail.test.com

Address: 172.16.17.86

> set type=mx

> test.com

Server:         172.16.17.86

Address:        172.16.17.86#53

 

test.com        mail exchanger = 5 mail.test.com.

>exit

三、

四、安裝mysql伺服器（用資料庫儲存使用者資訊）

        http://downloads.mysql.com

#groupadd mysql

#useradd –g mysql –s /bin/false –M mysql

#tar -zxvf mysql-5.0.22.tar.gz -C /usr/local/src/

#cd /usr/local/src/mysql-5.0.22/

#yum install ncurses-devel

#./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 /usr/local/src/mysql-5.0.22/support-files/my-medium.cnf /etc/my.cnf

#cd /usr/local/mysql
#chown -R mysql:mysql .
#bin/mysql_install_db –user=mysql
#chown -R root .
#chown -R mysql var
#bin/mysqld_safe –user=mysql &

#cd /usr/local/src/mysql-5.0.22/

#cp support-files/mysql.server /etc/rc.d/init.d/mysqld

#chmod 700 /etc/rc.d/init.d/mysqld

#chkconfig –add mysqld

#chkconfig mysqld on

#/usr/local/mysql/bin/mysqladmin ping

mysqld is alive

# /usr/local/mysql/bin/mysqladmin version

配置庫檔案搜尋路徑

# echo “/usr/local/mysql/lib/mysql” >> /etc/ld.so.conf
# ldconfig -v
新增/usr/local/mysql/bin到環境變數PATH中
#export PATH=$PATH:/usr/local/mysql/bin
#ln -sv /usr/local/mysql/bin/* /usr/bin/
#service mysqld restart
