repo追加
Nginx官网有yum的repo公开，可以从这里下载安装。
首先进入服务器，切换到root权限下。在[/etc/yum.repos.d/]下创建文件nginx.repo。文件内容计入如下：
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
追加后可以通过ls命令查看
# ls -l /etc/yum.repos.d/
total 32
。。。
-rw-r--r--. 1 root root 100 Dec 24 01:53 nginx.repo
安装Nginx
确认nginx包
# yum info nginx

系统启动时自动启动进程设定。

启动和停止
# systemctl start nginx
浏览器输入本地IP:80可以看到如下效果
Welcome to nginx!
如果打不开的话，可能时80端口没有打开。通过以下命令打开。

# firewall-cmd --reload
然后重启服务
# systemctl restart nginx
停止服务命令。
# systemctl stop nginx
