Checking Your Pre-Installation Configuration on Linux
Explaining how to install CentOS Linux is beyond the scope of this documentation. For information on how to installe CentOS, refer to the CentOS documentation:
http://wiki.centos.org/documentation
Following are some considerations for CentOS Linux installation.
- 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.
- 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.
- 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.
- When prompted, select Firewall as disabled. Your file server should be behind a firewall, but not be configured as one.
- When prompted, select SELinux as disabled.
-
In a terminal, enter the following commands:
sudo chkconfig iptables off
sudo service iptables stop
-
In a terminal, enter the following commands:
sudo systemctl disable firewalld
sudo systemctl stop firewalld
- Verify if SELinux is enabled by reviewing the contents of the SELinux config file:
more /etc/selinux/config
- 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
- If the value is set to something other than
disabled
, open the file using a text editor and change the value todisabled
.
- Once the file is modified and saved, reboot the computer.
