The Opsview Monitor installation package will create the Users
and Groups, as shown in the table below, if they do not already exist. Nevertheless,
you can also create them yourself but, you must create the Users and Groups
verbatim, as we shown in the table. Finally, a User should be assigned the Group(s) as shown below.
nagios, nagcmd, opsview
If you use an external authentication system, then you may
need to change the local User and Group files and recommend that these Users
and Groups are set up locally to remove the dependency on your external system.
Additionally, the web server user will need to be in the nagcmd group which
will, of course, be subject to your distribution.
The nagios user
needs write permissions to its home directory. The Opsview Monitor installation
will update the .profile (or .bash_profile) in the nagios user’s home
directory to source the profile, /usr/local/nagios/bin/profile; this is required to allow the setup of several Opsview Monitor environment variables. If
this is not set up on your system, you can run /usr/local/nagios/installer/set_profile, as the nagios user.
