Unable to install openJDK 8 in Red Hat

问题

I am trying to install openJDK 8 in my machine using yum, as per this https://openjdk.java.net/install/ .

But I can't see open openJDK 8 in yum repository.

[root@test ~]# yum search jdk
Loaded plugins: downloadonly, product-id, refresh-packagekit, security,
              : subscription-manager

If your version is too old you don't have the packages included or you have to enable some more repositories first to get the packages.

To list enabled repos:

subscription-manager repos --list-enabled

To enable third party repo:

subscription-manager repos --enable rhel-7-server-optional-rpms

When your version isn't to old you can make an yum update and fetch all new packages. Then you should be able to install JDK 8. Here is another good tutorial how to install JDK-8 on Red-Hat.

https://developers.redhat.com/articles/using-java-rhel-7-openjdk-8/

If you use an older Red-Hat version you have to install it on your own.
