无法通过套接字'/var/lib/mysql/mysql.sock'连接到本地MySQL服务器(2)

我只是在我的WordPress网站上手动安装了一个新的插件,在MySQL中为插件的条目创建了一个表,当我尝试打开使用该插件的页面时,我收到此错误:

DataTables warning (table id = 'to-do_list'): An error occurred while 
connecting to the database 'wordpress_clouse'. The error reported by the 
server was: SQLSTATE[HY000] [2002] Can't connect to local MySQL server 
through socket '/var/lib/mysql/mysql.sock' (2)

这是我的配置文件中列出的MySQL信息(我认为是正确的):

"type" => "Mysql",
"user" => "root",
"pass" => "******",
"host" => "localhost",
"port" => "",
"db"   => "******"

这是/etc/my.cnf文件的主要内容:

# The following options will be passed to all MySQL clients
[client]
#port       = 3306
socket      = /var/run/mysqld/mysqld.sock

# The MySQL server
[mysqld]
#port       = 3306
socket      = /var/run/mysqld/mysqld.sock
log_error   = mysqld.err

skip-networking

我已经看过类似错误的答案,但没有一个解决方案适合我.任何帮助,将不胜感激.
