HEL5.8_64全部源码编译搭建postfix，目前卡在sasl & courier-authlib认证这一块上快一个月了，导致无法发邮件 以下
为部分安装代码


手动安装mysql
[root@dns src]# tar xf mysql-5.5.28-linux2.6-x86_64.tar.gz -C /usr/local/
[root@dns src]# cd /usr/local/
[root@dns local]# mv mysql-5.5.28-linux2.6-x86_64 mysql
[root@dns local]# ln -sv /usr/local/mysql/include /usr/include/mysql
[root@dns local]# echo "/usr/local/mysql/lib" >> /etc/ld.so.conf.d/mysql.conf
[root@dns local]# ldconfig -v
[root@dns local]# sed -i '45a\/usr/local/mysql/man' /etc/man.config
[root@dns local]# echo "PATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh
[root@dns local]# source /etc/profile
[root@dns local]# groupadd mysql
[root@dns local]# useradd -r -g mysql mysql
[root@dns local]# cd mysql
[root@dns mysql]# chgrp -R mysql .
[root@dns mysql]# mkdir /mdata
[root@dns mysql]# chown -R mysql.mysql /mdata
[root@dns mysql]# scripts/mysql_install_db --datadir=/mdata --user=mysql
[root@dns mysql]# cp support-files/my-large.cnf /etc/my.cnf
[root@dns mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@dns mysql]# service mysqld start
Starting MySQL.The server quit without updating PID file (/usr/local/mysql/data/dns.xxoo.com.pid).[失败]
[root@dns mysql]#
[root@dns mysql]# vi /etc/my.cnf
# The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql.sock
添加下面一行
datadir = /mdata/
[safe_mysqld]
err-log = /var/log/mysqld.log
pid-file = /mdata/localhost.localdomain.pid

安装courier-authlib，支持mysql

1. 先编译安装libtool-2.4.2.tar.gz
[root@dns src]# tar xf libtool-2.4.2.tar.gz
[root@dns src]# cd libtool-2.4.2
[root@dns libtool-2.4.2]# ./configure
[root@dns libtool-2.4.2]# make
[root@dns libtool-2.4.2]# make install
2. 编译安装courier-authlib-0.62.4.tar.bz2
[root@dns src]# tar xf courier-authlib-0.62.4.tar.bz2
[root@dns src]# cd courier-authlib-0.62.

[root@dns authdaemon]# find / -name socket
/usr/lib/cups/backend/socket

是不是没有socket文件，导致sasl认证通不过呢？ 求各位大虾牛马鬼神分析下
