-
Depending on your operating system, use the appropriate command to check the status of the MySQL server. For example, on Linux, you might use:
lua
-
-
-
systemctl status mysql -
If MySQL is not running, start it using the appropriate command for your system (e.g.,
sudo systemctl start mysqlon Linux).

my.cnformy.iniand is located in the MySQL configuration directory. The socket path is often specified under the[mysqld]section.
- Ensure that the socket path specified in your MySQL configuration file is correct. This file is usually named

Verify MySQL Service is Running on the Correct Port:

-
Restart MySQL Server:
- After making any changes to the configuration, restart the MySQL server for the changes to take effect.
-
Check Disk Space:
- Ensure that there is enough disk space available on the server. A lack of disk space can sometimes cause MySQL to fail.
