8.11.1 ProblemYou need to create some new user or system groups. Any server programs that you install should have their own users and group. 8.11.2 SolutionUse groupadd. This command creates a new group, using the system values configured in /etc/default/useradd and /etc/skel/: # groupadd newgroup You can create a system group with -r flag: # groupadd -r newgroup The -r flag is a Red Hat-specific option. If your version of groupadd does not have it, you'll have to specify the next available system group number: # groupadd -g 127 newgroup Look in /etc/group to see the next available group number. 8.11.3 DiscussionIt's a good idea to stick to a consistent group numbering scheme. Linux doesn't care, for the most part, but for your own sanity it's essential. Red Hat system groups are 0-499; Debian's are 100-999. See the "Discussion" section in Recipe Recipe 8.2 for more information on numbering schemes. 8.11.4 See Also
