解决不能通过mysql.sock连接MySQL问题的办法  

　　这个问题主要提示是 不能通过 /tmp/mysql sock 连到服务器 而php标准配置正是用过 /tmp/mysql sock 但是一些mysql安装方法将mysql sock放在/var/lib/mysql sock或者其他的什么地方 你可以通过修改/etc/f文件来修正它 打开文件 可以看到如下的东东 　　[mysqld] 　　socket=/var/lib/mysql sock 　　改一下就好了 但也会引起其他的问题 如mysql程序连不上了 再加一点 　　[mysql] 　　socket=/tmp/mysql sock 　　或者还可以通过修改php ini中的配置来使php用其他的mysql sock来连 这个大家自己去找找　　　　或者用这样的方法:　　ln s /var/lib/mysql/mysql sock /tmp/mysql sock 　　　　还有:　　phpmyadmin的说明书有说 　　The error message Warning: MySQL Connection Failed: Can t connect to local MySQL server through socket /tmp/mysql sock ( ) is displayed What can I do? 　　　　For RedHat users Harald Legner suggests this on the mailing list: 　　　　On my RedHat Box the socket of mysql is /var/lib/mysql/mysql sock In your php ini you will find a line 　　mysql default_socket = /tmp/mysql sock 　　change it to 　　mysql default_socket = /var/lib/mysql/mysql sock 　　Then restart apache and it will work 　　　　Here is a fix suggested by Brad Ummer in the phpwizard forum: 　　　　First you need to determine what socket is being used by MySQL 　　To do this telnet to your server and go to the MySQL bin directory In this directory there should be a file named mysqladmin Type /mysqladmin variables and this should give you a bunch of info about your MySQL server including the socket (/tmp/mysql sock for example) 　　Then you need to tell PHP to use this socket 　　Assuming you are using PHP or better you can specify the socket to use when you open the connection To do this in phpMyAdmin you need to plete the socket information in the config inc php 　　For example: $cfg[ Servers ][$i][ socket ] = /tmp/mysql sock ; lishixinzhi/Article/program/MySQL/201311/29312
