Jenkins requires Java7 or above and Servlet 3.1 to function. Java8 is recommended. Jenkins requires a fair amount of memory to operate well. Smaller installations should start around 256MB-1GB.
To check your current kernel version, open a terminal and use uname -r to display your kernel version:
$ uname -r 3.10.0-229.el7.x86_64
