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

Question

I'm trying to use a fresh installation of MySQL on Windows Subsystem for Linux (Ubuntu) and can't seem to ever connect to it. I always get the error: WSL: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I've tried:

• Switching the configuration to use localhost instead of sockets (I instead get an error saying I can't connect through localhost)
• Using --skip-grant-tables by editing /etc/mysql/mysql.conf.d/mysqld.cnf and restarting

The file /var/run/mysqld/mysqld.sock never shows up either, though I figure this is because WSL doesn't have perfect socket support to begin with but it should still work. I suspect the problem might be specific to WSL and maybe I should try updating to WSL2? I don't know what else the issue could be.

Answer 1

I had the same issue.

Follow these steps provided by Microsoft: Add or connect a database with WSL

1. Update your Ubuntu packages: sudo apt update
2. install MySQL with: sudo apt install mysql-server
3. Start a MySQL server: sudo /etc/init.d/mysql start
4. Start the security script prompts: sudo mysql_secure_installation
5. Open the MySQL prompt: sudo mysql

Answer 2

I have the same issue solved through the following steps.

Put these lines at the end of the file /etc/mysql/my.cnf

[mysqld]                                                                                                                
bind-address = 0.0.0.0                                                                                                    
user=root                                                                                                               
pid-file     = /var/run/mysqld/mysqld.pid                                                                                
socket       = /var/run/mysqld/mysqld.sock                                                                               
port         = 3306                                                                                                                                                                                                                              

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

Then put these commands on terminal NOTE: if dir is not there then create one.

chmod 777 -R /var/run/mysqld
chmod 777 -R /var/lib/mysql
chmod 777 -R /var/log/mysql

Then start mysql using below command.

mysqld

Then open a new terminal and connect using the below command

mysql -uroot -pYourPass

Hopefully, it will work thanks.

Answer 3

Although M. Hamza Rajput 's answer is working (checked), it might be the case that the problem happens simply because mysql is NOT running

Thus, start mysql service:

sudo service mysql start

and then you can call the secure installation

sudo mysql_secure_installation

Answer 4

I have to run mkdir /var/run/mysqld and then service mysql start everytime I want to run mysql. No clue why... here looking for answers but very annoying.
