Checking Your Pre-Installation Configuration on Linux

Following are some considerations for CentOS Linux installation. Explaining how to install CentOS Linux is beyond the scope of this document—refer to the CentOS documentation.

1. Download the CentOS Linux documentation from: http://wiki.centos.org/documentation

2. Before installing Linux, make sure the distribution you will be installing is 64-bit. Harmony 14 will not work if the OS is not 64-bit.

3. When installing CentOS Linux, perform a Custom installation and select to install Everything to ensure that you get all the packages necessary to run Harmony.

4. When prompted, select Firewall as disabled. Your file server should be behind a firewall, but not be configured as one.

5. When prompted, select SELinux as disabled.

Harmony has been tested and certified for use on the GNOME windows manager.

Harmony works best with a minimum screen resolution of 1280 pixels x1024 pixels x 24-bit. If CentOS cannot detect your monitor, configure the monitor as a generic CRT or an LCD with this resolution and a 60 Hz refresh rate. Alternatively, consult your monitor manufacturer's documentation.

If you are new to Linux, it is recommended that you create a boot disk to facilitate recovery.

1. Verify if SELinux is enabled by reviewing the contents of the SELinux config file:

more /etc/selinux/config

2. Locate the line that starts with SELINUX= and verify that the value is set to disabled:

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#    enforcing - SELinux security policy is enforced.

#   permissive - SELinux prints warnings instead of enforcing.

#    disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#    targeted - Targeted processes are protected.

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

3. If the value is set to something other than disabled, open the file using a text editor and change the value to disabled.

4. Once the file is modified and saved, reboot the computer.
