讓我們重點關注如下描述：
Pre-Built Linux Packages for Stable
To enable automatic updates of Linux packages set up the yum repository for the RHEL/CentOS distributions, or the apt repository for the Debian/Ubuntu distributions.
To set up the yum repository for RHEL/CentOS, choose the corresponding nginx-release package from the list:
This package contains yum configuration file and a public PGP key necessary to authenticate signed RPMs. Download and install it, then run the following:
yum install nginx
Alternatively, a repository configuration can be added manually without installing the nginx-release package. Create the file named /etc/yum.repos.d/nginx.repo with
the following contents:
[nginx] name=nginx repo baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/ gpgcheck=0 enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5” or “6”,
for 5.x or 6.x versions, respectively.
方式一
點擊“CentOS 6”這個鏈接下載一個rpm文件，然後安裝之
>wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
>rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm
這個rpm並非完整的nginx，而是contains yum configuration file and a public PGP key necessary to authenticate signed RPMs。意思是說這個rpm安裝完成後已經添加了響應的yum配置信息文件和對rpm進行簽名使用的公鑰。
安裝玩這個包後我們執行如下命令查看yum的respo文件：
不難發現/etc/yum.repos.d目錄下多了一個nginx.repo文件,這個文件存放的是nginx的repository 配置。這個文件之前是沒有的。查看這個文件的內容：
接下來使用如下命令真正安裝nginx：
>yum install nginx -y
方式二
手動創建一個文件/etc/yum.repos.d/nginx.repo
>touch /etc/yum.repos.d/nginx.repo
編輯文件內容爲：
[nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1
接下來使用如下命令查看可以安裝的nginx rpm資源
安裝之
查看nginx是否安裝成功
>which nginx
查看nginx幫助信息
>nginx -h
查看nginx版本
>nginx -V
啓動nginx
>nginx
通過查看端口判斷啓動是否成功
>netstat -antp|grep nginx
通過瀏覽器訪問也可以判斷是否安裝成功：
http://serverip/
出現以下內容表示成功！！！
