Use the following information to install the DNCA software
to your physical server or virtual machine. If you are deploying your Network Capture Application to
a cloud-based environment, refer to the installation procedures for
those environments.
Procedure
- Log in to the server by using the root account.
Note: The installation must be run as root.
- Open a command prompt.
-
Enter yum install Discover-DNCA-<nn.n.n>-<rrr>.<distro>.<architecture>.rpm
to install the DNCA software.
Where:
- <nn.n.n> is the build version number.
- <rrr> is the RPM revision number. The revision numbers is
usually a single digit number.
- <distro> is an identifier for the Linux™ distribution, such as "RHEL n" for
Red Hat Enterprise Linux release
n.
- <architecture> is
i686,
x86_64.
By default, the DNCA software is installed in
/usr/local/dncauser. You specify the alternate directory by using the
rpm command's --prefix option along with the installation and upgrade
commands.
The following are some sample rpm invocations.
rpm -i --prefix=/opt/Discover Discover-DNCA-<nn.n.n>-<rrr>.<distro>.i386.rpm
rpm -U --prefix=/home/Discover Discover-DNCA-<nn.n.n>-<rrr>.<distro>.i386.rpm
When you do not use the --prefix option during an install or upgrade,
RPM uses the default installation directory that is specified in the
DNCA package file, which is /usr/local/dncauser. Once you relocate a
package, you must specify the alternate directory when you apply upgrades so that the
package correctly checks for and updates previous installations.
Results
When the files are extracted from the rpm package, follow
the post-installation checklist to validate the installation and begin
the configuration process.
