Linux Installation Best Practices

How you install Linux has an impact on Dell OpenManage Network Manager’s installation. Here

are some tested best practices:

•

You can install Linux in its Desktop option, or if you select Basic Server (default) - choose

additional packages: XWindows, Basic / Core Gnome Desktop without Gnome utilities,

although we suspect any Gnome will work).

•

Turn off SE Linux in /etc/selinux/config. Change SELINUX=disabled. This typically requires

a reboot.

•

You must install compatibility library from installation media (so it is compatible with

installation)

compat-libstdc++-33.x86_64 3.2.3-69.el6 @InstallMedia.

Also: verify that

/etc/hosts

points to new name-use the following command and you

should see similar output.

[qa@rh6Test Desktop]$ cat /etc/hosts

10.18.0.241rh6Test.localrh6Test# Added by NetworkManager

127.0.0.1localhost.localdomainlocalhost

::1rh6Test.localrh6Testlocalhost6.localdomain6localhost6

Upgrading on Linux

The following are best practices for upgrading from a previous OpenManage Network Manager

version on a Linux machine:

Make sure Red Hat is not installed with a MySql database option (or remove the Linux MySql

first).

Ensure you have installed the 32-bit Linux Libraries, as described below.

Verify your previous version’s installation application server starts without excpetions

Back up the database, and any other resources that need manual installation. Consult Release

notes for a list of these.

Proceed with the upgrade.

Disable Firewalls

System->Administration->Firewall - You may be prompted to enter the root password; the

password dialog may be hidden behind the Firewall Configuration Startup dialog.

Directories and Permissions

Create the directory for the installation:

Open a terminal.

Change to Super User: su <enter> password: []

Create directory and configure its ownership and permissions:
