How Do I Restart MySQL Server?

by admin on September 28, 2005 · 38 comments

in Tip that matters

Each distribution comes with a shell script (read as service) to restart / stop / start MySQL server. First login as root user and open shell prompt (command prompt).

First login as root user. Now type the following command as per your Linux distro:

A) If you are using mysql on RedHat Linux (Fedora Core/Cent OS) then use following command:

* To start mysql server:

/etc/init.d/mysqld start

* To stop mysql server:

/etc/init.d/mysqld stop

* To restart mysql server

 /etc/init.d/mysqld restart

Tip: Redhat Linux also supports service command, which can be use to start, restart, stop any service:

# service mysqld start
# service mysqld stop
# service mysqld restart

(B) If you are using mysql on Debian / Ubuntu Linux then use following command:

* 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

try the other commands –

# service mysqld restart

These usually work for me

I’m really embarrased to ask this, but I’m really new to linux + mysql. I installed mysql following the proceadure in, then I try to run your restart command and I get: -bash: /etc/init.d/mysql: No such file or directory.
I’m using mysql 5.0 over Debian… I’m sure I missed some configuration little detail, what can it be?
Any response is well appreciated :)

mysqld_safe is the recommended way to start a mysqld server if you install it from source or
mysqld_safe &

The correct method to install it via apt-get under Debian and Ubuntu Linux. Type the following to install
apt-get install mysql-server-5.0 mysql-client-5.0
Type the following to start:
/etc/init.d/mysql start

What’s about Darwin with the ‘launchd’ installed? How do I restart mysql?

10 Dom-2000 May 12, 2009 at 1:32 pm

You can also use:
# kill mysqld
.. wait till it shuts down – you can check by
# ps ax | grep mysql
then start it:
# cd /usr/local/mysql/bin (or where your mysql is installed)
# ./mysqld_safe &

For fedora, You must start mysqld everytime you boot up your pc, using /etc/init.d/mysqld start
If you stop without knowing it is starting it will show errors, you must start first, ok?

Hi, everyone. I’ve developed a project in php which requires one shell file as backup/output, one same file – manually updated. Between these two shell files if anyone is changed, the newer should update the older one. I’ve done it already by shell script but after the update process I need to restart the service I’m working on. I know the terminal command which is “/etc/init.d/service_name restart” but when I put this in my shell file it doesn’t work. Everything else are working but not the restart command. Can anyone help me out? Thanks in advance.

I have got a problem with MySQL. I can’t connect to the server, get the message: Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)

I am running Kubuntu 9.10,

I had moved my MySQL database from my stationary PC to my laptop. Everything seemed to function OK, but so I got the preceding error message both from MySQL Navigator, Knoda and trying to connect from the terminal window. Restarting the server didn’t help. Where to search for the error? I am new to MySQL.

thank you verymuch

I have somehow lost all permissions on root and don’t currently have any other users. This is troublesome because I don’t have the privileges to give myself privileges or create new users. I also don’t know how to start the mysql program with –skip-grant-tables, or I would try this. Any help would be great.

27 casino August 16, 2010 at 10:51 pm

thanks all ok!

28 munna October 6, 2010 at 4:05 pm

i am using fedora 13 . one problem with me is mysql is not start by using the command /etc/init.d/mysqld start if i use thid command then showing the message Command not found. Similar command is: ‘mysql’
please solve my problem……….

29 Daniel T October 12, 2010 at 5:13 am

Sounds like you only have a part of MySQL installed, you also need the client.
Try ‘sudo apt-get install mysql-client-5.1′

and then follow the steps mentioned above to start. During the install you should be prompted for setting the MySQL password etc.

Can’t locate mysqld and mysqladmin after deploying from rpm package. I can’t deploy rpm without using root. So can anyone help me? It keeps saying cannot start mysql on root, asked to check security part in the manual. But can’t search manual because it has error. Can someone help?

32 Lelik October 19, 2011 at 12:59 am

thanx much!

33 sysadmin January 5, 2012 at 12:53 pm

Does anybody knows what is the difference between “/etc/init.d/mysqld restart” and “/etc/init.d/mysqld reload”?

34 evans February 2, 2012 at 8:49 am


I find it difficult to start mysql

35 Tyrotoxism March 2, 2012 at 4:30 pm

Don’t forget:
$ service mysql start
$ service mysql stop
$ service mysql restart
These worked for me, at least.

36 Vijay May 6, 2012 at 5:56 am

thanks a bunch. my EC2 server was acting up and all it needed was a quick restart.

37 Vijay May 6, 2012 at 5:57 am


For me the shortcut is
$ service mysqld start
$ service mysqld stop
$ service mysqld restart

38 Mau August 25, 2012 at 6:23 am
