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

This error message indicates that the MySQL server is not running or is not set up correctly on the local machine. The application is trying to connect to the server through a socket file located at `/var/lib/mysql/mysql.sock`, but the socket file cannot be found or accessed.
To resolve this issue, try the following steps:
1. Check if the MySQL server is running by running the command `systemctl status mysqld`. If the server is not running, start it using the command `systemctl start mysqld`.
2. If the server is running, make sure that the MySQL socket file exists at the location `/var/lib/mysql/mysql.sock`. If it doesn't exist, create it using the command `touch /var/lib/mysql/mysql.sock`.
3. Check the MySQL configuration file (`/etc/my.cnf`) to make sure that the `socket` parameter is set to `/var/lib/mysql/mysql.sock`. If it is not set, add the following line to the file:
```
[mysqld]
socket=/var/lib/mysql/mysql.sock
```
4. If the above steps do not resolve the issue, try restarting the MySQL server using the command `systemctl restart mysqld`.
If none of these steps work, there may be a deeper issue with the MySQL installation or configuration. Consider seeking help from a MySQL expert or consulting the official MySQL documentation.
