For the ones who used to have the sysv-rc-conf (Debian family distros) or ntsysv (Red Hat family distros), there is another alternative compatible also with systemd. You can use the serman2 tool from the archlinux repository. It's a small program written in python and does the job similarly. Just download it, uncompress and copy the script into your /usr/local/bin directory. Eventually, in some distros you may have a problem to find the systemctl, which can be easily solved with a symbolic link with the command below:
wget -c http://xyne.archlinux.ca/projects/serman/src/serman-2014.7.tar.xz
tar xvf serman-2014.7.tar.xz
sudo cp serman-2014.7/serman2 /usr/local/bin
# in some distros the sysctl is located under the /bin directory
ln -s /bin/systemctl /usr/bin/systemctl
There you go, now you just execute the serman2 command in your shell
