CentOS 5 上安装 nginx

#yum install nginx

补充：

如果遇到以下错误提示：

[root@localhost ~]# yum -y install nginx
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * addons: centos.ustc.edu.cn
 * base: centos.ustc.edu.cn
 * extras: centos.ustc.edu.cn
 * updates: data.nicehosting.co.kr
Setting up Install Process
No package nginx available.
Nothing to do

原因是：

对CentOS系统而言，Nginx不在标准库里，不过可以使用EPEL库，EPEL参考资料（http://www.cyberciti.biz/faq/rhel-fedora-centos-linux-enable-epel-repo/）。 使用EPEL库安装Nginx，命令如下： # rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm

检查一下 yum list:

#yum repolist

[root@localhost ~]# yum repolist

如果没有 EPEL， 运行：

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

版本号需要调整， 如果找不到。

[root@localhost ~]# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm

再检查一下 yum list,

[root@localhost ~]# yum repolist

如果 EPEL 更新成功， 则运行：

#yum install nginx
