## 安装Nginx
打开nginx官方网站的下载页`http://nginx.org/en/download.html`：
:-: 
拉倒页面最下端，这里是预编译包，我们选择稳定版（stable version）nginx-1.14.0安装，点击进去：
:-: 
我们按照说明，创建nginx的repo文件
~~~
[root@localhost ~]# vim /etc/yum.repos.d/nginx.repo
~~~
内容如下：
~~~
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
~~~
好了，可以安装nginx了
~~~
[root@localhost ~]# yum install nginx -y
~~~
瞬间就安装完了，查看一下版本：
~~~
[root@localhost ~]# nginx -v
~~~
返回：
~~~
nginx version: nginx/1.14.0
~~~
版本正确，看看nginx服务的状态：
~~~
[root@localhost ~]# systemctl status nginx.service
~~~
返回：
~~~
● nginx.service - nginx - high performance web server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
Active: inactive (dead)

~~~
服务没启动，启动它：
~~~
[root@localhost ~]# systemctl enable nginx.service
[root@localhost ~]# systemctl start nginx.service
[root@localhost ~]# systemctl status nginx.service
~~~
返回：
~~~
