部署mysql版本信息

version: 5.6.21

具體現(xiàn)象：

mysql服務(wù)能夠正常啟動如下：

[root@localhost ~]# service mysqld restart

Shutting down MySQL.. SUCCESS! 

Starting MySQL.. SUCCESS! 

登陸mysql庫出現(xiàn)如下錯誤：

[root@localhost ~]# mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

解決方法：

經(jīng)過對如上錯誤分析，/var/lib/mysql/目錄下缺少mysql.sock（mysql的套字節(jié)）

[root@localhost ~]# find / -name mysql.sock

/tmp/mysql.sock

只要系統(tǒng)中存在mysql.sock這個文件，接下來解決問題就會很好辦如下操作：

[root@localhost ~]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

重啟服務(wù)

[root@localhost ~]# service mysqld restart

Shutting down MySQL.. SUCCESS! 

Starting MySQL.. SUCCESS! 

重新登陸

[root@localhost ~]# mysql

Welcome to the MySQL monitor.  Commands end with ; or \g.
