只是笔记而已，不是很详细，莫怪
opensips搭建问题解决笔记：

/var/lib/mysql/mysql.sock 转移到了 /data/mysql/mysql.sock
（http://www.cnblogs.com/fuhj02/p/3541173.html）
软连接
ln –s /data/mysql/mysql.sock /var/lib/mysql/
还是出错

检查了一下软连接还是/my.cnf 的socket 都做了修改
在[mysql] 加上了socket=/tmp/mysql.sock
还是出现如下错误：

猜想是不是 以前装过mysql卸载，在重新装mysql 出现的问题 。
当前数据库版本：4.1.11-standard-log
查看mysql进程 ps -ef|grep mysqld
发现 地址/DB_home/mysql/data/my.cnf 下面 修改了这个文件 还是出现错误如下

远程访问数据库
mysql -h 202.107.195.117 -uroot -pdcs.1234
会出错
修改权限后 出错如下

怀疑是编译的mysql 和 系统启动的mysql 不是同一个。
1、查找出已安装的版本
rpm -qa | grep mysql
mysql-5.0.95-5.el5_9
php-mysql-5.1.6-44.el5_10
mysql-server-5.0.95-5.el5_9
mysql-devel-5.0.95-5.el5_9
2、查询已安装好的mysql 会显示安装的地址
whereis mysql
mysql: /usr/bin/mysql /usr/lib/mysql /usr/local/bin/mysql /usr/local/bin/mysql.server /usr/include/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz
额，我发现服务器里面装了一堆的mysql组件，版本也有2个。最后选择全部卸载。
全部卸载
（http://blog.csdn.net/rosten/article/details/25096159）
安装mysql
（http://blog.csdn.net/rosten/article/details/25098331）
重新配置 就好了。我去。
