sudo systemctl start mysql
sudo systemctl enable mysql
```
5. To check if the MySQL service is running, you can use the following command:

sudo systemctl status mysql
```
6. To secure your MySQL installation, you can run the script that comes with the package:
```
sudo mysql_secure_installation
```
7. Follow the prompts to set a password policy, remove anonymous users, disallow root login remotely, and remove test databases.
8. You can now access the MySQL server using the root account and the password that you set during installation.
Note: If you specifically need MySQL 5.7 instead of the latest version, you can use the following command to install it:
```
