How do I start/stop mysql server?

I found this link for MySQL database:

# To install MySql database:

sudo apt-get install mysql-server

# To start MySql server:

/etc/init.d/mysql start

# To stop MySql server:

/etc/init.d/mysql stop

# To restart MySql server:

/etc/init.d/mysql restart

# To check the status of MySql server:

/etc/init.d/mysql status

In case you want to investigate why a DB MYSQL can stop or crash you should check the log on the following location:

/var/log/mysql/error.log

Eventually the mysql crash happens for the reason of not having enought memory:

And the solution for adding more swap memory is in this link:
