chkconfig in Ubuntu?

[ejms07]

How can I do a chkconfig on Ubuntu. That's I'm trying to do...

#chkconfig dhcp on

and

#chkconfig squid on

under /etc/init.d


Thanks guys!

check out update-rc.d

man update-rc.d

[ejms07]

I tried update-rc.d but the services (dhcp & squid) are not starting automatically. When I ran the command it says that "the links already exist"

I think chkconfig is nice as well (actually, coming from an SGI Irix background as well as Redhat). But I doubt you'll see it on Ubuntu soon.

update-rc.d is a bit more sensitive - but does work.

To see what links are around for "squid" say, try a :

find /etc/rc* -name '*squid*'

Also check the logs for startup problems (and the /etc/init.d file).

Thanks for the bash script. Will try it when I get home.

This is probably a better solution than attempting to get the RedHat chkconfig source and try to compile it against Kubuntu.

There is an alternative for editing runlevels that can be used just like chkconfig:
http://sysv-rc-conf.sourceforge.net/

To install:
sudo apt-get install sysv-rc-conf
sysv-rc-conf

Excerpt from the manual:

DESCRIPTION

sysv-rc-conf gives an easy to use interface for managing /etc/rc{runlevel}.d/ symlinks. The interface comes in two different flavors, one that simply allows turning services on or off and another that allows for more fine tuned management of the symlinks. It's a replacement for programs like ntsysv(8) or rcconf(8).

sysv-rc-conf can also be used at the command line when the desired changes to the symlinks are already known. The syntax is borrowed from chkconfig(8).

Thank you very much!
sysv-rc-conf is almost like chkconfig! :D

If you actually want the chkconfig command in ubuntu, do the following:


$ apt-get install libnewt0.51
$ ln -s /usr/lib/libnewt.so.0.51 /usr/lib/libnewt.so.0.50
$ wget http://www.tuxx-home.at/projects/chkconfig-for-debian/chkconfig_1.2.24d-1_i386.deb
$ dpkg --force-all -i chkconfig_1.2.24d-1_i386.deb


I found this whilst looking for a solution myself - It's a debian solution which works...

I'll check both of them out. chkconfig was the only command that I was still missing from my days of using primarily redhat. If this works the way I remember it you'll both have made my week!

btw, apt is the reason I switched to Debian. apt > yum :D

sysv-rc-conf does rock. Personally I find it better than chkconfig, but it's nice to have both options ;)

I've only had it on a testing machine so far, but everything looks very promising! Thanks again for the suggestion. I'll let you know when I'm ready to move it into production.

No probs mate. Have fun. :mrgreen:

Does any of these work as a drop-in replacement for chkconfig? I have summarized the issue here: http://ubuntuforums.org/showthread.php?p=2212100#post2212100

Found a chkconfig rpm that installs clean.

1. Download chkconfig-1.2.24h-7.i386.rpm from http://rpmfind.net//linux/RPM/PLD/dists/ac/ready/i386/chkconfig-1.2.24h-7.i386.html

2. Convert rpm to deb with: sudo alien chkconfig-1.2.24h-7.i386.rpm

3. Double-click on the deb file. This will invoke the package installer.
