安装环境:redhat5.8 2.6.18-194.el5 i386

mysql 5.6.25 (mysql> SELECT VERSION();)

安装前

关闭sendmail服务 service sendmail stop &&chkconfig sendmail off

安装gcc环境 yum -y install gcc+

确认开发环境已安装;

Development Libraries

Development Tools

启动mysqld数据库服务. service mysqld start

启动saslauthd服务 service saslauthd start

添加postsfix账户:groupadd -g 2525 postfix

useradd -g 2525 -u 2525 -s /sbin/nologin -M postfix

添加postdrop用户组 groupadd -g 2526 postdrop

useradd -g 2526 -u 2526 -s /sbin/nologin -M postdrop

开始安装postfix

3.解压源码包 tar xf postfix-2.10.8.tar.gz

2.进入解压后的文件夹执行:make makefiles 'CCARGS=-DHAS\_MYSQL -I/usr/local/mysql/include -DUSE\_SASL\_AUTH -DUSE\_CYRUS\_SASL -I/usr/include/sasl -DUSE\_TLS ' 'AUXLIBS=-L/usr/local/mysql/lib -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto'

1.  说明:
    
    \-I/usr/local/mysql/include指明MySQl头文件路径
    
    AUXLIBS=-L/usr/local/mysql/lib指明MySQL库文件路径
    
    \-DUSE\_SASL\_AUTH 启用SASL支持
    
    \-I/usr/include/sasl 指明SASL头文件路径
    
    \-DUSE\_TLS支持SMTPS协议

makefile过程中可能遇到的错误:

\*\*\* \[alldig.o\] 错误 127 缺少gcc环境

3.make \*\*make install

安装路径和一些安装时的配置说明:

install\_root: \[/\] /

tempdir: \[/root/postfix-2.10.8\] /tmp/postfix 安装过程中的临时文件目录

config\_directory: \[\] /etc/postfix 配置文件目录

command\_directory: \[\] /usr/sbin 二进制文件目录

daemon\_directory: \[\] /usr/libexec/postfix

data\_directory: \[\] /var/lib/postfix

html\_directory: \[\] /usr/local/apache/htdocs html文件目录

mail\_owner: \[\] postfix

mailq\_path: \[\] /usr/bin/mailq

manpage\_directory: \[\] /usr/local/man man文件

newaliases\_path: \[\] /usr/bin/newaliases

queue\_directory: \[\] /var/spool/postfix

readme\_directory: \[\] no

sendmail\_path: \[\] /usr/sbin/sendmail

setgid\_group: \[\] postdrop

make install过程中可能的错误:

libpcre.so.1文件缺失 ln -s /usr/local/lib/libpcre.so.1 /lib

libmysqlclient.so.18文件缺失 ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18

4.提供SysV启动脚本

vi /ettc/init.d/postfix

\#!/bin/bash

\# postfix Postfix Mail Transfer Agent

\# chkconfig: 2345 80 30

\# description: Postfix is a Mail Transport Agent, which is the program \\

\# that moves mail from one machine to another.

\# Source function library.

\# Check that networking is up.

\[ $NETWORKING = "no" \] && exit 3

\[ -x /usr/sbin/postfix \] || exit 4

\[ -d /etc/postfix \] || exit 5

\[ -d /var/spool/postfix \] || exit 6

RETVAL=0

prog="postfix"

start() \{

\# Start daemons.

echo -n $"Starting postfix: "

/usr/bin/newaliases >/dev/null 2>&1

/usr/sbin/postfix start 2>/dev/null 1>&2 && success || failure $"$prog start"

RETVAL=$?

\[ $RETVAL -eq 0 \] && touch /var/lock/subsys/postfix

echo

return $RETVAL

stop() \{

\# Stop daemons.

echo -n $"Shutting down postfix: "

/usr/sbin/postfix stop 2>/dev/null 1>&2 && success || failure $"$prog stop"

RETVAL=$?

\[ $RETVAL -eq 0 \] && rm -f /var/lock/subsys/postfix

echo

return $RETVAL

reload() \{

echo -n $"Reloading postfix: "

/usr/sbin/postfix reload 2>/dev/null 1>&2 && success || failure $"$prog reload"

RETVAL=$?

echo

return $RETVAL

abort() \{

/usr/sbin/postfix abort 2>/dev/null 1>&2 && success || failure $"$prog abort"

return $?

flush() \{

/usr/sbin/postfix flush 2>/dev/null 1>&2 && success || failure $"$prog flush"

return $?

check() \{

/usr/sbin/postfix check 2>/dev/null 1>&2 && success || failure $"$prog check"

return $?

restart() \{

stop

\# See how we were called.

exit 1

esac

exit $?

\# END

给予x权限 chmod +x /etc/init.d/postfix

--------------------

将postfix加入服务列表:chkconfig --add postfix

postfix的配置文件

master 核心进程,配置文件/etc/postfix/master.cf

mail配置 /etc/postfix/main.cf

参数 = 值:参数必须顶格写,以空白字符开头的行被认为是上一行的延续

smtp协议命令(原语)

helo

ehlo

mail from:

rcpt to

data

启动服务测试 service postfix start

\[root@localhost postfix-2.10.8\]\# telnet localhost 25

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).
