With every major enterprise Linux release, Red Hat adds a number of new daemons to the startup of the server. Most of these daemons has a very clear function. I have however pondered what all the daemons are for. Although nice to have many of the daemons simply eats away at your resources and if not needed should really be disabled.
Red Hat was kind enough to release the following information in the Red Hat Magazine article, with the heading: “Understanding your (Red Hat Enterprise Linux) daemons“.
Of course the above information is very handy for CentOS, which is based on Red Hat Enterprise Linux.
