Yum Install Java

When deploying a production system, it is recommended to use Yun to deploy the Java environment

1. Open Epel Source

#yum-y Install Epel-release

2. Installing Java

# yum-y Install java-1.6*

Epel source is currently installed in version 1.6

3. Upgrading Java Edition

(1). Enable Epel test source

Edit Vi/etc/yum.repos.d/epel-testing.repo

#baseurl =http://download.fedoraproject.org/pub/epel/testing/6/$basearch

(2). Deactivate Epel Normal source
