Linux环境，通过mysql -uroot -p命令进入mysql的时候，总是报错ERROR 2002 (HY000): Can't connect to local MySQL server through socket
通过service mysqld restart 重启mysql，也是报错“ Couldn't find MySQL server (/usr/bin/mysqld_safe)”
之前我在安装的时候，mysql自定义了安装路径，my.cnf的配置都已经设置好了。但是这次想再进入mysql和重启mysql的时候，都出现了问题。于是
找到my.cnf文件，进行查看：
结果发现我的my.cnf文件有两个。在/etc/mysql这个目录下的my.cnf是之前删除的数据库的配置文件，新mysql用的配置文件是/etc/my.cnf,
而/etc/mysql这个里面的my.cnf文件的配置都是之前删除数据库的配置，所以讲这个my.cnf文件删除或者改名，则问题解决
