[root@localhost ~]# yum list |grep nginx
No package nginx available.
[root@localhost ~]# //給跪了，什麼鬼，怎麼沒有nginx的rpm?算了，直接自己手動配一個官網repo吧
[root@localhost ~]# //訪問nginx官網，進入dowload頁面，翻到底部的Pre-Build Package，選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/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.
---------------------------
[root@localhost ~]#
[root@localhost ~]# //大意就是：創建/etc/yum.repos.d/nginx.repo文件，貼入模板內容，替換相應的系統和軟件版本號
[root@localhost ~]#
[root@localhost ~]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# vi nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0

Thank you for using nginx.
ok安裝好了，下面就是配置的事情
配置nginx為反向代理服務器
設置nginx開機自啟動
[root@localhost yum.repos.d]# cd /etc/nginx
[root@localhost nginx]# chkconfig nginx on
Note: Forwarding request to 'systemctl enable nginx.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
設置nginx的反向代理規則

最後一步
因為我們nginx的反向代理服務器是部署在10.1.1.230上，它本身也是內網服務器，所以需要在路由器上配一個路由轉發規則：
所有從外網80端口進來的請求，都轉發到nginx所在的服務器，由nginx來負責轉發。
路由器設置：虛擬服務器
WAN口 wan1
WAN端口 80 常用服務： DNS(53)
LAN端口 80
內網IP 10.1.1.230
協議： 全部
ok，大公告成～
【重要補充：】
對了，還忘記了交代：還需要一個自己的域名(myweb.org)，才可以這樣去使用二級域名來解析內網應用。
如果沒有，可以申請阿裡雲服務，然後在路由器上，來綁定內網入口的網絡服務商分配給動態IP(這步很簡單，就是路由器上設置填上申請的動態域名就好了)
這裡的工作，屬於准備期工作，申請啊備案啊，還是很繁瑣的，本次沒有記錄下來～
