Currently, my MySQL server starts on every server boot. For a couple reasons, this is undesirable behavior. Is there a way to disable this behavior?

There are two Guis I can think of. From Applications -> Ubuntu Software Center search for "boot up manager". After installing you will find it in the System -> Administration -> BootUP-Manager. Another is Webmin. Webmin uses your browser. After installing point your browser to https://localhost:10000/ Look for services and work it from there.

    This method didn't work for me on 16.04 – Mostafa Ahangarha Mar 22 '17 at 11:29

To prevent mysql from starting on boot:

  1. Open the terminal: Ctrl+Alt+T

  2. Open the mysql.conf file: nano /etc/init/mysql.conf

  3. Comment out the start on line near the top of the file, the start on might be spread across two lines, so comment out both. (comment adding # at the beginning)

If you want to manually start mysql, use the following command:

service mysql start

Taken liberally from here.

    This is a very usefull answer for more than one initiation at start up. – maniat1k Mar 22 '12 at 15:26

    Tried, I have /usr/sbin/mysqld and /bin/sh /usr/bin/mysqld_safe running. Commented out everything but didn't helped. – Emin Mastizada Sep 16 '15 at 20:33
  • IMO this is the best answer. – simhumileco Jul 1 '17 at 19:52
  • in Linux Mint 18.2 Cinnamon I removed /etc/init/mysql.conf with no change. Mysql server still running on startup. @thebugfinder solution worked for me – flyingdrifter Nov 6 '17 at 14:24

Since 15.04 you can simply do:

sudo systemctl disable mysql

    Indeed. For 15.04, this is the answer you seek. – CommandZ Dec 3 '15 at 19:03
  • Awesome, finally I found a solution for this! The other methods don't work to me. – rneves Mar 22 '16 at 13:08
  • I can't start it again, how do I start mysql after the command? – rneves Mar 22 '16 at 13:21
  • @rneves did you try enable or reenable? – thebugfinder Apr 12 '16 at 23:48

    @thebugfinder I've tried enable, I don't know about reenable, but enable forces me restart the computer to start mysql again – rneves Apr 13 '16 at 14:56

Things have changed quite a bit in Ubuntu now. I think from version 11 onwards. MySQL is handled by Upstart while Apache still uses traditional SysV init scripts

For MySQL, you can use the new override feature in Upstart to modify the starting behaviour:

sudo echo "manual" >> /etc/init/mysql.override

For more info, see the section "Disabling a Job from Automatically Starting" in the Upstart Cookbook.

As Apache still uses the traditional SysV init scripts you can use

sudo update-rc.d -f apache2 remove

to remove the links from /etc/rcX.d or, alternatively use

sudo update-rc.d apache2 disable

which "disables" the script by changing it from a start script to a stop script. This is reversible by

sudo update-rc.d apache2 enable

Most of this information I got from here: https://askubuntu.com/a/40077/24678

  • If you want to restore the service sudo update-rc.d apache2 defaults – bentech Jan 17 at 10:20

Or if your really laze like me you could just open a Terminal session and then type:

sudo perl -pi.orig -e 's/start\s+on/#start\s+on/' /etc/init/mysql.conf && sudo perl -pi.orig -e 's/and\s+/#and/g' /etc/init/mysql.conf

You can then just issue a reboot command then your system will boot-up without mysql started.

    This command could be improved. It is adding a + leaving the line like this: #start+on blahblahblah but it works! – Lucio Dec 22 '13 at 0:41

Actually, there is also another method to accomplish this, via the sysv-rc-conf tool.

You can install it by typing

sudo apt-get install sysv-rc-conf

It allows you to take control over all available services, including running/stopping them in place and configuring services' operation per runlevel.

Edit: You have to run tis tool as root:

sudo sysv-rc-conf

You can use chkconfig tool package

$ chkconfig --level 345 mysqld off

    Please elaborate your answer. Why do you think this solves the question? You could e.g. add a link to a manual as reference. – Byte Commander Jul 28 '16 at 22:30
