can’t connect to local mysql server through socket ‘/var/run/mysqld/mysqld.sock

Hello! I’m experiencing a frustrating issue with my MySQL server and could really use some assistance. Whenever I attempt to connect to the local MySQL server, I keep getting the error message: “Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’.” I’ve checked that MySQL is supposed to be running on my system, but I’m not sure if the service is up and operating correctly.

I’ve looked into a few potential causes—like whether the MySQL service is actively running and whether the socket file indeed exists at the specified location—but I’m still stumped. I even tried restarting the MySQL service, but that didn’t seem to help resolve the issue.

Could this problem be related to incorrect permissions for the socket file or maybe a configuration issue in the MySQL settings? Alternatively, could the issue arise if MySQL has not been properly installed or configured? Any insights into how to troubleshoot this problem or steps to fix it would be greatly appreciated! Thank you for your help!

    1. Hey, so I just ran into this “can’t connect to local mysql server through socket ‘/var/run/mysqld/mysqld.sock'” error, and honestly, I have no clue what’s going on!

      I think it has something to do with MySQL not running or maybe the socket file is missing? 😅 Like, I tried to check if MySQL is actually up, but I don’t even know the right command! Is it mysql.server start or service mysql start? Someone told me using sudo might help, but I’m a bit scared of messing things up.

      Also, I was looking in that /var/run/mysqld/ folder, and I couldn’t find mysqld.sock anywhere! Did I do something wrong? Do I need to create that file or folder myself? Or is that something MySQL makes when it runs?

      Anyways, if anyone has tips for a noob like me, I’d totally appreciate it! I just want to connect without pulling out all my hair! 😬


    2. To troubleshoot the error “Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’,” you should first verify that the MySQL server is indeed running. You can do this by executing the command `systemctl status mysql` or `service mysql status` in the terminal. If the server is not running, you can start it with `sudo systemctl start mysql` or `sudo service mysql start`. Additionally, check the MySQL error log (usually located in `/var/log/mysql/error.log`) for any issues related to startup failure, which might provide insights into what’s preventing the server from running.

      If the MySQL server is running but you still encounter the socket error, ensure that the socket file exists at the specified path (`/var/run/mysqld/mysqld.sock`). If it does not, it may indicate that the MySQL server is configured to use a different socket path. You can check your MySQL configuration file (typically found at `/etc/mysql/my.cnf` or `/etc/my.cnf`) for the socket setting under the `[mysqld]` section. Ensure that the MySQL user has the necessary permissions to access the socket file, and if the socket path is incorrect, update it accordingly. Restart MySQL after making any configuration changes to apply your edits.
