建立一个 PHP 文件, 显示 phpinfo():
用浏览器打开:
在此页面，找到mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket信息:
2. 获取 MySQL socket 路径
通过控制台进入 MySQL, 输入命令: STATUS, 查找 UNIX socket 值
#mysql -u root -pEnter password: Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 8Server version: 5.7.11 MySQL Community Server (GPL)Copyright (c) 2000, , Oracle and/or its affiliates.

3. 这时候, 你对比 mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket 和 通过 MySQL UNIX socket 发现不一样, 这就是 mysql_connect(); 警告的原因: PHP 配置 mysql 有问题.
4. 重新配置 PHP, 打开php.ini修改mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket 的值为: /tmp/mysql.sock
pdo_mysql.default_socket=/tmp/mysql.sock mysql.default_socket=/tmp/mysql.sock mysqli.default_socket=/tmp/mysql.sock
或者修改f的socket：
[client] socket=/tmp/mysql.sock [mysqld] socket=/tmp/mysql.sock
5.重启nginx或者apache
