I am trying to figure out how to install haveged on Cloud Linux. It doesn't seem to be avail in the repo, and trying to a do a make install does not work. My question is:

Is haveged compatible with CL, and if so, is there a repo I can simply add to install it?

All of the directions I have read on shows to simply yum install it, but it's not available on CL repos. Thats why I am not sure if it's compatible. I am trying to generate entropy on a server I cannot plug anything into.

I've not run Cloud Linux, but this tutorial from Digital Ocean shows how to install it from source:

visit the download page and choose the latest release tarball (1.7a at the time of this writing). After downloading the tarball, untar it into your current working directory:

# tar zxvf /path/to/haveged-x.x.tar.gz

Now you compile and install:

# cd /path/to/haveged-x.x
# ./configure
# make
# make install

By default, this will install with a prefix of /usr/local, so you should add something similar to the following to /etc/rc.local (or your system's equivalent) to make it automatically start on boot (adjust the path if necessary):

# Autostart haveged
/usr/local/sbin/haveged -w 1024

Run the same command manually (as root) to start the daemon without rebooting

Note: the current version is 1.9.1 as of today.

  • Is it recommended to use an entropy-boosting random-number generator like this nowadays? – ewwhite Mar 31 '16 at 20:28
  • @ewwhite - not 100% sure how "recommended" it is. It's certainly been performance-improving for me recently. – warren Mar 31 '16 at 21:07
  • For what types of workloads? – ewwhite Mar 31 '16 at 21:08
  • @ewwhite lots of key generation (and running HP's Sever Automation somewhat better (as mentioned in this old [question](http://serverfault.com/q/303935/2321))) – warren Mar 31 '16 at 21:12
  • @ewwhite - I've also noticed Apache being more responsive with SSL pages since adding the use of haveged – warren Mar 31 '16 at 21:12
