報了:Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)的錯。
解決方法:
1.查看是不是mysql權限的問題 (默認安裝方式為 yum -y install mysql)
轉到 /etc/rc.d/init.d/目錄下
[root@xxx init.d]# mysqld status
2018-06-11 15:20:47 0 [Warning] TIMESTAMP with implicit DEFAULT value is depreca ted. Please use --explicit_defaults_for_timestamp server option (see documentati on for more details).
2018-06-11 15:20:47 0 [Note] mysqld (mysqld 5.6.40) starting as process 12917 .. .

2018-06-11 15:20:47 12917 [Note] mysqld: Shutdown complete
其中的第一個錯誤是
2018-06-11 15:20:47 12917 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!
這是因為MySQL為了安全,不希望root用戶直接啟動mysql。
所以可以在 /etc/my.cnf裏增加 user=mysql 來指定mysql的用戶
--------------------------------------------------------------------
[mysqld]
user=mysql
--------------------------------------------------------------------
[root@xxx search]# mysql

可以看到mysql啟動成功。
