centos系統EPEL安裝使用教程

EPEL全稱Extra Packages for Enterprise Linux，官方翻譯為 企業版 Linux 附加軟體包。顧名思義，他可以擴充你的軟體庫，安裝很多軟體時能省去很多時間。比如最近很火的PHP的DoS漏洞，Bug 61461，在EPEL下面只需要一條命令就能將PHP升級為5.9，避免重新編。

老高推薦新安裝的centos系統都先安裝此附加軟體包！

安裝命令：

yum install epel-release

RHEL 5.x / CentOS 5.x

32 位

rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm64 位元

rpm -Uvh http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpmRHEL 6.x / CentOS 6.x

32 位

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm64 位元

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm這樣就可以很方便的安裝一些常用的軟體，比如要安裝 Nginx ，即可通過如下命令，而無需自行編譯安裝：

yum -y install nginx

沒有報錯的話，那麼EPEL就安裝完畢了。

如果上述命令還是解決不了問題，那就必須有針對性的安裝了。
