How do I stop a program running at startup in Linux. I want to remove some apps from startup to allow them to be managed by supervisord e.g apache2

  • That's exactly why I didn't tag it... I'm looking for all the variations as I work with quite a few different distros. – Frozenskys Aug 10 '10 at 21:15

Depending on your distro use the chkconfig or update-rc.d tool to enable/disable system services.

On a redhat/suse/mandrake style system:

sudo chkconfig apache2 off 

On Debian:

sudo update-rc.d -f apache2 remove

Checkout their man pages for more info.

  • Why do you need -f (I assume it's force) on Debian based distros? – Frozenskys Aug 10 '10 at 20:05

    There are two sets of files in play here. You've got the actual init script in /etc/init.d/ and you have the links to it in your runlevel directory /etc/rcrunlevel.d/. These guys point to the script in /etc/init.d/ If you don't use -f update-rd.d will fail UNLESS the script in /etc/init.d/ is already deleted. If you do use -f update-rc.d will properly delete the link files regardless of whether or not the /etc/init.d/ script is deleted. – jacksonh Aug 10 '10 at 20:38
  • Ah, that makes a lot of sense, I'd forgotten that the runlevel scripts were just links to the init scripts. Thanks for the extra explanation. – Frozenskys Aug 10 '10 at 21:18

If you are dealing with a modern Ubuntu system and a few other distros you may have to deal with a combination of traditional init scripts and upstart scripts. Managing init scripts is covered by other answers. The following is one way to stop an upstart service from starting on boot:

# mv /etc/init/servicename.conf /etc/init/servicename.conf.disabled

The problem with this method is that it does not allow you to start the service using:

# service start servicename

An alternative to this is to open the servicename.conf file in your favorite editor and comment out any lines that start with:

start on

That is, change this to

#start on ...

where the "..." is whatever was after "start on" previously. This way, when you want to re-enable it, you don't have to remember what the "start on" parameters were.

Finally, if you have a new version of upstart you can simply add the word "manual" to the end of the configuration file. You can do this directly from the shell:

# echo "manual" >> /etc/init/servicename.conf

This will cause upstart to ignore any "start on" phrases earlier in the file.

On recent Fedora and Future RHEL systems

systemctl disable httpd.service

will disable the httpd service

  • Thanks! I had tried many methods, but this systmctl command worked fine. – loved.by.Jesus Aug 19 at 15:40

To list all the startup services

    systemctl

To stop a service from running on start up

    sudo systemctl disable servicename

For instance if we need to stop running ssh server at startup

    sudo systemctl disable sshd.service

We can enable this again using

    sudo systemctl enable sshd.service

Almost every linux distributions use systemd for bootstrapping startup services. So above commands work for most of the distros.

  • Welcome to U&L, and thank you for your contribution! I'd like to point out that this question is about eight years old now, so the accepted answer was correct for the time. Using systemctl may be correct now, but it's correct for a different question. – Jeff Schaller Mar 16 at 12:50
  • @Prince thanks for the detailed explanations. It helped me to understand how the boot startup works in my Xubuntu. – loved.by.Jesus Aug 19 at 15:57

Slackware and Arch linux have similar methods of stopping/starting processes at boot, different than the Ubuntu and Redhat-style examples given above.

In both Slackware and Arch linuxes, sh scripts exist in directory /etc/rc.d, typically one script per daemon, or one script per subsystem.

For example, Slackware starts the Apache web server with a script /etc/rc.d/rc.httpd, called at the appropriate time during system startup with an argument of "start". Arch linux has differently-named scripts, but the same sort of thing goes on.

To keep some process from starting during system boot, on Slackware, you just make the appropriate script in /etc/rc.d not executable. To keep Apache from starting at the next boot:

chmod -x /etc/rc.d/rc.httpd

To stop an Apache that got started at boot: /etc/rc.d/rc.httpd stop You'll need to be root.

Arch is a bit more complex. The file /etc/rc.conf, a shell script, has an array DAEMONS. To keep Apache from starting at boot, you'd change this line in /etc/rc.conf:

DAEMONS=(hal syslog-ng network netfs crond alsa sshd httpd ntpd postgresql)

To this line:

DAEMONS=(hal syslog-ng network netfs crond alsa sshd ntpd postgresql)

To stop an already executing apache, you'd execute /etc/rc.d/httpd stop as root.
