Slow startup on Tomcat 7.0.57 because of SecureRandom

by

I faced same issue of tomcat being too slow to start. I followed this article on DigitalOcean and installed haveged instead of using urandom.

haveged is a solution which will not compromise on security.

haveged allows generating randomness based on variations in
code execution time on a processor. Since it’s nearly impossible for
one piece of code to take the same exact time to execute, even in the
same environment on the same hardware, the timing of running a single
or multiple programs should be suitable to seed a random source. The
haveged implementation seeds your system’s random source (usually
/dev/random) using differences in your processor’s time stamp counter
(TSC) after executing a loop repeatedly

How to install haveged

Follow the steps in this article. https://www.digitalocean.com/community/tutorials/how-to-setup-additional-entropy-for-cloud-servers-using-haveged
