CoffeeCP for cPanel requires the following:
- CentOS 6x or 7x
- CloudLinux 6x or 7x
- Root Access
- WHM x3 or paper_lantern
- Shell Access for Java users
- Recommended: haveged**
**We strongly recommend installing haveged. See details below.
Haveged is an entropy generator and will improve startup times exponentially.
This is not unique to CoffeeCP, but for any operating system serving Java.
The simplest way to install Haveged is via the Epel repository:
rpm -i epel-release-latest-6.noarch.rpm
rpm -i epel-release-latest-7.noarch.rpm
Once the Epel repository is installed, install haveged with:
yum -y install haveged
Once haveged is installed, disable the Epel repository at /etc/yum.repos.d/epel.repo by changing
name=Extra Packages for Enterprise Linux 6 - $basearch
If you do not wish to enable the EPEL repository, haveged can be built from source.
While it is not required to install haveged, it will make a seriously noticable difference in performance.
Haveged can also improve overall HTTPD peformance as well.
