1，nginx下载，linux版本和windows版本分别是

linux：http://nginx.org/download/    windows：nginx.org/en/download.html

2，yum 安装，首先安装nginx的源

Install the prerequisites:

sudo yum install yum-utils

To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents:

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

 

注意各版本的区别：Nginx官网提供了三个类型的版本
1、Mainline version：Mainline 是 Nginx 目前主力在做的版本，可以说是开发版
2、Stable version：最新稳定版，生产环境上建议使用的版本
3、Legacy versions：遗留的老版本的稳定版

 

By default, the repository for stable nginx packages is used. If you would like to use mainline nginx packages, run the following command:

sudo yum-config-manager --enable nginx-mainline

也可以安装稳定版

　　sudo yum-config-manager --enable nginx-stable

　　

To install nginx, run the following command:

sudo yum install nginx
