ERROR 2002(HY000):无法通过套接字'/var/run/mysqld/mysql.sock'连接到本地MySQL服务器(2)

Question

我收到了这个错误

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)

即使我已经设法通过ubuntu中的命令行启动mysql

mysql stop/waiting
mysql start/running, process 17691

但是,当尝试访问该站点时,我在尝试访问mysql时遇到数据库连接错误以及上述错误 mysql -u root -p

我检查了我的错误日志,我看到了这个

谢谢

Answer 1

我的问题已经解决,检查进程是否在Ubuntu 12.04上运行

ps ax | grep mysql

然后答案是它没有运行,所以我做到了

sudo service mysql start

或者试试

sudo /etc/init.d/mysql start

Answer 2

首先,请确认已安装mysql-server.安装mysql-server但是以某种方式损坏时我有同样的错误.我完全卸载mysql 并重新安装它.

sudo apt-get remove --purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server mysql-client

Answer 3

I had the same problem when i installed xampp on my system. The mysql server looks for /var/run/mysqld/mysqld.sock but the mysql.sock file was in xampp folder so i used

 find / -name '*.sock'

to find the mysql.sock file and then used

ln -s <the file location> /var/run/mysqld/mysqld.sock

to get a link for the*.sock file then tried mysql and it ran without error. Hope this could solve yours.

Remember to create the directory if it does not exists.

Answer 4

应将客户端设置为与服务器设置一致.

[client]
port        = 3306
socket      = /var/run/mysqld/mysqld.sock

[mysqld]
user        = mysql
pid-file    = /var/run/mysqld/mysqld.pid
socket      = /var/run/mysqld/mysqld.sock
port        = 3306

Answer 5

这花了我很多年才弄清楚,但你可以尝试相同 -

1 - 更新和升级

sudo apt-get update
sudo apt-get upgrade

2 - 清除MySQL服务器和客户端(如果已安装).

sudo apt-get purge mysql-server mysql-client

3 - 安装MySQL服务器和客户端

sudo apt-get install mysql-server mysql-client

4 - 测试MySQL

mysql -u root -p
> enter root password

***应该在/var/run/mysqld/mysql.sock中找不到套接字

4 - 使用nano的vi配置mysqld.cnf

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

将bind-address从127.0.0.1更改为localhost

bind-address            = localhost

**写和退出

5 - 重启MySQL

sudo /etc/init.d/mysql restart

6 - 检查mysql

mysql -u root -p
> enter root password

4. sudo pkill mysqld
5. sudo service mysql restart
6. mysql -u root -p

Answer 7

最近我在mysql中遇到了这个错误 ERROR 2002 (HY000)：

无法通过套接字连接到本地MySQL服务器

'/var/lib/mysql/mysql.sock'（111）

因为我忘了开始我的mariadb。只需在您的终端上键入此命令即可。

systemctl start mariadb.service

Answer 8

在 linux 终端中，我运行以下步骤，他们帮助了我

1.首先列出所有安装的mysql包

  sudo dpkg -l | grep mysql

2.使用列出的命令删除列出的包

  sudo apt-get --purge autoremove <package name>

3.重新安装mysql服务器

  sudo apt-get install mysql-server

这对我有用，希望这对你也有用。

或者试试

sudo apt-get remove --purge mysql-\

然后重新安装

sudo apt-get install mysql-server mysql-client

Answer 9

如果你仔细观察，你会发现差异：

• 服务器监听/var/run/mysqld/mysqld.sock
• 客户端尝试连接/var/run/mysqld/mysql.sock

您必须调整其中之一。
