部署mysql版本信息
version: 5.6.21
具體現象:
mysql服務能夠正常啟動如下:
[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:
經過對如上錯誤分析,/var/lib/mysql/目錄下缺少mysql.sock(mysql的套字節)
[root@localhost ~]# find / -name mysql.sock
/tmp/mysql.sock
只要系統中存在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
[root@localhost ~]# service mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL.. SUCCESS!
重新登陸
[root@localhost ~]# mysql
