Adding Bright to an existing system doesn't work! What now?

Adding Bright to an existing system doesn't work! What now?


The manual does discourage using the add-on method. If the prerequisites listed in the manual are not met, then that may be the reason. So, read that section of the manual carefully first.


If that doesn't help, the following run-through of the add-on method on a centOS 6.5 virtual machine illustrates the installation process so that you can compare matters to see if anything unexpected shows up. At the end of the procedure, some troubleshooting issues that may come up are dealt with.


Installation Process


1. Use a fresh Install of CentOS 6.5 (base OS)

This is the base server.

2. mount Bright DVD

[root@adel-addon ~]# mount -o loop /dev/sr0 /mnt

3. install bright-installer:

a. enable EPEL repository

[root@adel-addon ~]# wget

[root@adel-addon ~]# rpm -ivh epel-release-6-8.noarch.rpm

b. install dependencies

[root@adel-addon ~]# yum install createrepo

[root@adel-addon ~]# yum install perl-Expect

c. Install bright-installer RPM

[root@adel-addon ~]# rpm -ivh /mnt/addon/bright-installer-6.1-401_cm6.1.noarch.rpm

4. Install bright-installer pre-requisites

[root@adel-addon ~]# yum install lynx dialog bind mysql-server xorg-x11-server-Xorg tcl
