php - 无法连接: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

Question

当我通过 php 脚本连接数据库时，它会显示

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

用户名和密码正确。

my.cnf的一些内容

[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:我将其更改为socket =/var/lib/mysql/mysql.sock php脚本仍然显示“/var/lib/mysql/mysql.sock”？然后运行

  mysqladmin -u root -p status

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

Answer 1

问:你的 my.conf 仍然显示“/var/lib/mysql/mysql.sock”吗？

问:“/var/lib/mysql”目录是否存在？

问:你的 mysql 用户(或者更好的是 mysql 组)有 writer 权限吗？

如果是这样，请尝试重新启动mysql，看看会发生什么。

要尝试的另一件事是创建一个mysql.sock并明确授予它权限:

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