yum安装java

在部署生产系统时，推荐使用yun来部署java环境

1.开启epel源

#yum -y install epel-release

2.安装java

# yum -y install java-1.6*

epel源目前安装的是1.6版本

3.升级java版

       (1).启用epel测试源

 编辑vi /etc/yum.repos.d/epel-testing.repo

[epel-testing]
name=Extra Packages for Enterprise Linux 6 - Testing - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/testing/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=testing-epel6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

(2).停用epel正常源

# vi /etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

(3).升级java版本

# yum -y install java-1.7*

注意：yum升级时不能跨级升级java，不能直接从1.6升级到1.7
