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
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
sudo update-rc.d -f apache2 remove

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:
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
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.
On Ubuntu 10.04 you can control some startup programs from the GUI.
To list all the startup services
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.
1) tap superkey on you keyboard 2) search for 'Startup Applications' 3) choose which program you want to disable 4) hit like to this answer if worx.
