Chkconfig command
 

Hi All,

I am a newbie to Linux world. So please excuse if this is a dumb question.

I was trying to learn the chkconfig command. When I list the services with that command, I don't see all services getting listed.

[ec2-user@machine ~]$ chkconfig --list

Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.

If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.

choose_repo 0 off 1 off 2 on 3 on 4 on 5 on 6 off
netconsole 0 off 1 off 2 off 3 off 4 off 5 off 6 off
network 0 off 1 off 2 on 3 on 4 on 5 on 6 off
rh-cloud-firstboot 0 off 1 off 2 off 3 off 4 off 5 off 6 off
rhnsd 0 off 1 off 2 on 3 on 4 on 5 on 6 off
[ec2-user@machine~]$

If I try to list nginx service, I am getting this error.

[ec2-user@machine ~]$ chkconfig --list nginx

Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.

If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.

error reading information on service nginx: No such file or directory


Any help would be appreciated.

What distro are you using? Form you output it doesn't look like nginx is supposed to run.

Have a look at Redhat's guide.

Nginx is running and I am using RHEL7

[ec2-user@machine~]$ sudo netstat -anp | grep nginx
tcp 0 0 0.0.0.0:81 0.0.0.0:* LISTEN 759/nginx: master p
unix 3 [ ] STREAM CONNECTED 15398 759/nginx: master p
unix 3 [ ] STREAM CONNECTED 15397 759/nginx: master p

[ec2-user@machine~]$ systemctl | grep nginx
nginx.service loaded active running nginx - high performance web server

[ec2-user@ip-10-17-6-90 ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)
[ec2-user@machine~]$

chkconfig is only provided for legacy use of RH SysVinit services that have not been converted to systemd.

The only services you will see are those that reside in /etc/init.d. For RH 7, there should be a README file there that describes what is going on, and references to documentation.

This Cheat Sheet might help you.
