剛安裝完mysql，進行執行測試，報Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’錯誤，

[[email protected] mysql]# /usr/local/mysql/bin/mysqld_safe
131206 22:42:51 mysqld_safe Logging to ‘/var/log/mysqld.log’.
131206 22:42:51 mysqld_safe Starting mysqld daemon with databases from /data/mysql/data
131206 22:42:57 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
[

[email protected] mysql]# /usr/local/mysql/bin/mysql
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

檢查一下mysql的執行狀態
[[email protected] mysql]# ps -ef | grep mysql
root     32092  2108  0 22:43 pts/0    00:00:00 grep mysql

檢視/tmp資料夾的確沒有mysql.sock檔案，

通過find命令查詢

[[email protected]

/]# find / -name mysql.sock
/var/lib/mysql/mysql.sock

原來安裝到/var/lib/mysql/mysql.sock這個位置啦，我們需要修改my.cnf檔案

[[email protected] /]# vi /etc/my.cnf

[client]
character-set-server = utf8
port    = 3306
socket  = /var/lib/mysql/mysql.sock
……

儲存之後即出，重新啟動mysql。
