RH124 CentOS 7 Managing services with systemd

53 ratings | 8896 views
More videos like this online at http://www.theurbanpenguin.com Red Hat Enterprise Linux 7 and the subscription free version CentOS 7 now use systemd over upstart and the earlier SysV scriots. Of course then you need to take a look at managing services with the new tools. We will install the Apache web server and use this as an example of how we can manage services.

I enjoy your videos, however, I have to tell you. I have been a Linux administrator since the early 1990s when Linux was originally released. systemd is a mistake and completely unnecessary. There was nothing wrong with the system5 start up scripts. In my professional opinion, red hat has made a huge mistake with this one in version seven of their operating system.

@grimygrime systemctl controls systemd, which replaced the old SysV system, but systemd is backwards compatible (somewhat) and you can still use chkconfig and service commands. The input will just redirect to systemctl, and it will tell you so. Great video +theurbanpenguin, too tired to read a manpage right now so the sub 8 minute video was perfect. :)

So does the systemctl command basically replace the service and chkconfig commands?

systemctl is just one part of the systemd. Among other things systemctl combines the functionality of chkconfig and service; however there are more systemd units than just services and systemctl can work with units other than services which of course did not come into the remit of chkconfig and service
