下载Nginx
wget nginx.tar.gz http://nginx.org/download/nginx-1.11.3.tar.gz
解压源码
tar -zxvf nginx-1.11.3.tar.gz
然后进入目录编译安装 cd nginx-1.11.3 ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_spdy_module --with-http_stub_status_module --with-pcre 如果没有error信息，就可以执行下边的安装了： make make install
安装prce(重定向支持)和openssl(https支持，如果不需要https可以不安装。)
yum -y install pcre* yum -y install openssl*

启动nginx ./usr/local/nginx/sbin/nginx 重启或关闭进程： ./usr/local/nginx/sbin/nginx -s reload ./usr/local/nginx/sbin/nginx -s stop
浏览器中输入http://localhost:8080，效果如下
官方文档中的安装方法，设置源后直接安装，对于配置文件自动写入默认路径
1、设置安装源
To set up the yum repository for RHEL/CentOS, 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/$basearch/ gpgcheck=0 enabled=1 Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.
具体文件内容为：
[nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=0 enabled=1
2、执行以下命令安装
sudo yum install nginx
3、启动、停止nginx服务
sudo nginx sudo nginx -s stop
