故障状况:php网站连接mysql失败,但在命令行下通过mysql命令可登录并正常操作。
解决方案:
1、命令行下登录mysql,执行以下命令:
show variables like 'socket';
执行后会得到类似于如下回显:

"Variable_name"        "Value"
"socket"                  "/home/mysql/data/mysql.sock"
2、编辑php.ini,找到mysql.default_socket配置项,默认一般是空值(使用编辑Mysql时设置的sock路径),将此项添加值为上面回显中的"/home/mysql/data/mysql.sock":

; Default socket name for local MySQL connects.  If empty, uses the built-in
; MySQL defaults.
mysql.default_socket = /home/mysql/data/mysql.sock
3、重启php。
