無法連接：無法通過套接字「/var/lib/mysql/mysql.sock」連接到本地MySQL服務器（2）

Question

當我用PHP腳本連接我的數據庫，它顯示

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

用戶名和密碼是正確的。

的my.cnf

[client] 
#password  = your_password 
port   = 3306 
socket   = /data/mysql/mysql.sock 

# Here follows entries for some specific programs 

# The MySQL server 
[mysqld] 
port   = 3306 
socket   = /data/mysql/mysql.sock 
skip-external-locking 

PS的東西：我將其更改爲socket = /var/lib/mysql/mysql.sock PHP腳本仍然說 「/var/lib/mysql/mysql.sock」？然後運行

mysqladmin -u root -p status 

它顯示

mysqladmin: connect to server at 'localhost' failed 
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)' 
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists! 




service mysqld restart 


mysqld: unrecognized service 

Answer 1

問：你my.conf仍然說 「/var/lib/mysql/mysql.sock」？

問：目錄「/ var/lib/mysql」是否存在？

問：你的mysql用戶（或更好的，mysql組）有寫入權限嗎？

如果是這樣，請嘗試重新啓動mysql，看看會發生什麼。

附錄：

另一件事是嘗試到創建一個的mysql.sock並明確給它的權限：

cd /var/lib 
mkdir mysql 
touch mysql/mysql.sock 
chown -R mysql:mysql mysql
