34tfe

                      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'

• 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
#

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

RETVAL=0
prog="postfix"

start() {

echo -n $"Starting postfix: "
        /usr/bin/newaliases >/dev/null 2>&1

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

reload() {

abort() {

return $?
}

flush() {

return $?
}

check() {
/usr/sbin/postfix check 2>/dev/null 1>&2 && success || failure $"$prog check"
return $?
}

restart() {

# 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
