#### 1.因為CentOS默認不提供Nginx的Repo信息，所以需要手動添加才可以安裝，命令如下。
```shell
sudo rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
```
#### 2.查看哪些Nginx版本可以安裝
```shell
sudo yum --showduplicates list Nginx
```
#### 3.執行安裝命令
```shell
sudo yum install nginx.x86_64
```
#### 4.設置隨系統啟動
```shell
systemctl enable Nginx.service
```
#### 5.啟動Nginx
```shell
systemctl start Nginx.service
```
