ERROR 2002 (HY000): Can’t connect to local MySQL server through socket 解決辦法
故障描述：
啟動mysql 報錯：ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
1.先檢視mysql啟動狀態
#/etc/rc.d/init.d/mysqld status
2.mysql.sock位置查詢與驗證？
# find / -name mysql.sock/Data/mydata/mysql.sock
驗證目錄是否正確
#mysql -u root -p -S /Data/mydata/mysql.sock
備註：-S引數socket file檔案驗證
3.驗證mysql.sock檔案許可權和使用者是否正確？如果是許可權問題，則先改變許可權
#chown -R mysql:mysql /Data/mydata/mysql.sock
[[email protected] ~]# /etc/init.d/mysqld start
啟動 MySQL： [ OK]
4.永久解決
修改/etc/my.cnf
新增以下內容到/etc/my.conf:[client]
socket = /Data/mydata/mysql.sock
[mysqld]
socket = /Data/mydata/mysql.sock
