Installing haveged from Oracle repositories

In my previous blog, I mentioned the installation of the utility Haveged that is used to increase your entropy on non-gui systems. Since you can download it from the Oracle yum repository, I figured that I could install it from yum too, instead of using rpm. This prevents me from having to download it myself, and ensures I have the one that is applicable to my version of Linux.

Too bad it isn't in the default ol7_latest repo. So you have to either add the yum repo above or enable it.

To add it, you can do:

[vagrant@darlin-vce ~]$ sudo yum-config-manager --add-repo https://yum.oracle.com/repo/OracleLinux/OL7/developer_EPEL/x86_64

To remove it, you can remove the corresponding file from /etc/yum.repos.d:

[vagrant@darlin-vce ~]$ cd /etc/yum.repos.d/
[vagrant@darlin-vce yum.repos.d]$ ls
public-yum-ol7.repo
yum.oracle.com_repo_OracleLinux_OL7_developer_EPEL_x86_64.repo
[vagrant@darlin-vce yum.repos.d]$ sudo rm yum.oracle.com_repo_OracleLinux_OL7_developer_EPEL_x86_64.repo
[vagrant@darlin-vce yum.repos.d]$ ls
public-yum-ol7.repo

But it appears already registered in the repository list, but disabled:

[vagrant@darlin-vce yum.repos.d]$ sudo yum repolist all

....

To enable it just:

sudo yum-config-manager --enable ol7_developer_EPEL

As a response it will display the current configuration.
Then install haveged by:

sudo yum -q -y install haveged

To check if haveged is installed, do a yum -list:

[vagrant@darlin-vce ~]$ sudo yum list haveged
Loaded plugins: langpacks, ulninfo
Installed Packages
haveged.x86_64

This is drawn by combining this RHEL Tech-Doc with the repo content of my freshly installed OL7U5 box.

And that solves the note I had left in my previous blog post.
