当我通过 php 脚本连接我的数据库时，它显示
Could not connect: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
用户名和密码是正确的。
一些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：我把它改成socket = /var/lib/mysql/mysql.sock PHP 脚本仍然说"/var/lib/mysql/mysql.sock"？。 然后运行
mysqladmin -u root -p status
它显示
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
问：你的 my.conf 还说"/var/lib/mysql/mysql.sock"吗？
问：目录"/var/lib/mysql"是否存在？
问：您的 mysql 用户(或者更好的是 mysql 组(是否具有编写者权限？
如果是这样，请尝试重新启动mysql，看看会发生什么。
补遗：
要尝试的另一件事是创建一个 mysql.sock 并显式授予它权限：
cd /var/lib
mkdir mysql
touch mysql/mysql.sock
chown -R mysql:mysql mysql
