Ubuntu – How to start/stop thesql server

MySQLsudo

I tried to find in some articles describing how to correctly start & stop mysql server.

I found this link: How to start/stop MySql server on Ubuntu 8.04 | Abhi's Blogging World

I ran this command:

/etc/init.d/mysql start

but I see this error 

ERROR 1045 (28000) Access denied for user....

After I tried this command:

sudo /etc/init.d/mysql start

I entered my password, and again I see the same error.

Next command:

sudo /etc/init.d/mysql - root -p start

results in:

ERROR 1049 (42000) Unknown database 'start'.

And when I run this command: 

sudo service mysql start

MySQL server success started. Cool!

So, what's wrong with the other commands? Why do they result in error?

Your first two commands weren't run as root so that is expected behaviour. You need to be root to stop/start mysql.

However:

sudo /etc/init.d/mysql start

should work. Indeed it does, for me:

kojan:~> sudo /etc/init.d/mysql restart
[sudo] password for chris: 
Stopping MySQL database server: mysqld.
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..

I used restart rather than start, since it was already running, but the effect is the same. Are you sure you entered your password correctly? :) Have you edited your sudo config at all which would stop this working?

This one..

sudo /etc/init.d/mysql - root -p start

The arguments are wrong. an init.d script only takes start or stop or restart - just one word telling it what to do. You cannot give it multiple arguments as you were trying to do.

Anyway, the short answer is the one you actually got to work, is the recommended way. service is replacing all the init.d scripts over time, so you should get into the habit of using service. The page you link is 3 years old so has to be taken with some salt :)
