0.9.6-2 RELEASE NOTES

This maintenance upgrade is based on a kernel updated to the latest CentOS 2.6.32-279.22.1. It contains install and uninstall bug fixes, a more efficient BetterCPU method for moving users to and from jail and non-jail cores, and continued support for the latest MySQL versions. Take full advantage of the BetterCPU change by modifying the following setting after the upgrade is complete:

In /etc/betterlinux/cpud.conf.d/betterlinux-cpud.conf, change the default number of start_throttling seconds from 3 to 1. It should look like this:

start_throttling group=cpanel_users cpu_percent=50 seconds=1

FIRST TIME INSTALLATION (cPanel server)

For quick installation and updates, use the pre-built package for CentOS 6.0-6.3. Packages for other popular Linux distributions are coming soon.

Basic installation instructions:

• Go to https://www.betterlinux.com and login to your account.
• You will see a "My Downloads" button on the left side of the browser
• Select the distribution of your choice, tarballs, and license file; then move them to your server. They appear as follows:

betterlinux cpanel install betterlinux install license.key

Alternatively, the tarballs can be pulled down directly to the server by right clicking on the tarballs link in the downloads area to copy the url address and then using the wget command in combination with pasting in the tarball link. See the example below and supplement your CentOS version number:

wget http://repo.betterlinux.com/release/betterlinux-cpanel-install-0.9.6-2centos6*-x86_64.tar.gz wget http://repo.betterlinux.com/release/betterlinux-install-0.9.6-2centos6*-x86_64.tar.gz

• Unpack the tarballs:

tar –xvf betterlinux-cpanel-install-* tar –xvf betterlinux-install-*

• Unpacking the tarballs will create the directory .../betterlinux-install. Move the license.key file into the betterlinux-install directory.
• Change directory to betterlinux-install, and start bl-install:

./bl-install license.key

• Once the installation is complete, reboot your server.
• cd into the betterlinux-cpanel-install directory, run the bl-cpanel-install script, and answer the questions:

./bl-cpanel-install

Installation and cPanel configuration are now complete. CPU and IO throttling limits have been auto-configured and are now running on your system. If you want to make throttling limit changes, please refer to our online documentation. http://docs.betterlinux.com
