Installing
and Configuring Application Software
1.
It is possible for individual users to
install some applications in their home directories, drive space set aside for their own files and
customizations these applications are not available to other users without the
intervention of the system administrator.
2.
if an application is to be used by
more than one user, it probably needs to be installed higher up in the Linux
file hierarchy, which is a job that can be performed by the system
administrator only.
3.
The administrator can limit which
users may use which applications by creating a “group” for that application and
enrolling individual users into that group.
4.
New software packages might be
installed in /opt, if they are likely to be upgraded separately from the Red
Hat Linux distribution itself.
5.
By so doing, it’s simple to retain the
old version until you are certain the new version works and meets expectations.
6.
Some packages may need to go in
/usr/local or even /usr, if they are upgrades of packages installed as part of
Red Hat Linux.
7.
The location of the installation
usually matters only if you compile the application from source code.
8.
In Red Hat Package Manager (RPM)
packages automatically goes where it should.
