yum安裝java，yumjava

在部署生產系統時，推薦使用yun來部署java環境

1.開啟epel源

#yum -y install epel-release

2.安裝java

# yum -y install java-1.6*

epel源目前安裝的是1.6版本

3.升級java版

       (1).啟用epel測試源

 編輯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).升級java版本

# yum -y install java-1.7*

注意：yum升級時不能跨級升級java，不能直接從1.6升級到1.7
