checkconfig Ubuntu alternative?

[opethdisciple]

So in the Centos/Redhat world you can use checkconfig --level 35 etc.. to add services at differnet run levels.

I am trying to do something similar with Apache running on Ubuntu.

According to what I can find online the answer is something like:

update-rc.d apache2 default

or


update-rc.d apache2 enable 2345

But none of this works. If I restart the server the Apache services is not auto started on boot up.

Any ideas?

This doesn't seem to work either....

sudo systemctl enable apache2

You don't say what version of Ubuntu you are running but on Ubuntu 16.04 the systemctl method works for me:

# systemctl enable apache2
apache2.service is not a native service, redirecting to systemd-sysv-install
Executing /lib/systemd/systemd-sysv-install enable apache2

(hmmm .... it's a poor package which doesn't provide proper systemd startup stuff then)

After a reboot:

# systemctl status apache2
● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)
  Drop-In: /lib/systemd/system/apache2.service.d
           └─apache2-systemd.conf
   Active: active (running) since Sat 2016-11-19 22:07:57 GMT; 52s ago
     Docs: man:systemd-sysv-generator(8)

           ├─1288 /usr/sbin/apache2 -k start
           └─1289 /usr/sbin/apache2 -k start

So it has been started automatically on a reboot.

edit: I would also note that the chkconfig stuff is only correct for CentOS/RHEL prior to version 7.

I'm running Ubuntu 16.04.1 LTS.

Very strange on my home VM when I start the server the apache2 service does not start automatically.

andrew@ubuntu:~$ systemctl status apache2
● apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2; static; vendor preset: enabled)
Drop-In: /lib/systemd/system/apache2.service.d
└─apache2-systemd.conf
Active: inactive (dead)
Docs: man:systemd-sysv-generator(8)

I have ran systemctl enable apache2 yesterday.

Would be nice to get to the bottom of this as I have lots of Linux interviews coming up and if I can explain why a service cant start n start up...

I just ran systemctl enable apache2 again and rebooted and can confirm the process remains dead.
