About Haveged

Haveged is an entropy generator and will improve startup times exponentially.

This is not unique to CoffeeCP, but for any operating system serving Java.

Debian or Ubuntu:

apt-get install haveged

For RHEL systems, the simplest way to install Haveged is via the Epel repository:

CentOS 6x:

rpm -i epel-release-latest-6.noarch.rpm

CentOS 7x:

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 enabled=1 to enabled=0:

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.
