第一：yum 方式安装
1:参考http://nginx.org/en/linux_packages.html#stable
2:根据自己的系统类型进行更改
Pre-Built Packages for Stable version
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 “6” or “7”, for 6.x or 7.x versions, respectively.
3: 查看 yum list | grep nginx
安装 yum install nginx
4: nginx -v 查看版本
查看安装路径
rpm -ql nginx
得到安装路径后
5:最后启动nginx /usr/sbin/nginx
6:重启服务可以 使用
systemctl restart nginx 或者 systemctl reload nginx
以上就结束安装了，
