Не удается установить OpenJDK 1.8.0_45 через yum в RHEL 7.4

Question

Я пытаюсь установить OpenJDK 1.8.0_45 в моей RHEL 7.4 VM через ням. В настоящее время установлен OpenJDK 1.7. Это вывод релизной версии RHEL
rpm -qa |grep release
redhat-release-server-7.4-18.el7.x86_64
Что я хочу это

openjdk version "1.8.0_45"`  
OpenJDK Runtime Environment (build 1.8.0_45-b13)  
OpenJDK 64-Bit Server VM (build 25.45-b02, mixed mode).

Когда я пытался yum install java-1.8.0-openjdk это сообщение об ошибке, которое я получил:

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager  
This system is not registered with an entitlement server. You can use subscription-manager to register.  
Bad id for repo: root@iotaasmon1 yum.repos.d, byte = @ 4  
Repository epel is listed more than once in the configuration  
Repository epel-debuginfo is listed more than once in the configuration  
Repository epel-source is listed more than once in the configuration  
No package java-1.8.0-openjdk available.  
Error: Nothing to do

OpenJDK 1.8 также не отображается, когда я сделал yum search,

$ yum search openjdk

  Name and summary matches only, use "search all" for everything.  

Может кто-нибудь сказать мне, как установить или обновить до OpenJDK 1.8.
Пожалуйста, дайте мне знать, если потребуется дополнительная информация.
