+## Nginx配置
+
+### 方式A
+
+需要两个配置文件 `ip.conf` 和 `ip-sub.func`
+
+```
+# 进入nginx配置目录
+shell> cd /etc/nginx/conf.d
+
+# 从代码仓库复制配置文件
+shell> cp /var/www/echoIP/conf/nginx/methodA/ip.conf ./
+shell> cp /var/www/echoIP/conf/nginx/methodB/ip-sub.func ./
+
+# 修改配置文件，将ip.343.re改为需要部署的域名
+shell> vim ip.conf
+···
+shell> vim ip-sub.func
+···
+```
+
+重启Nginx服务
+
+```
+shell> nginx -s reload
+```
+
+### 方式B
+
+需要一个配置文件 `ip.conf` ，但需要额外占用除80与443之外的一个端口，默认为TCP/1601，可按需修改
+
+```
+# 进入nginx配置目录
+shell> cd /etc/nginx/conf.d
+
+# 从代码仓库复制配置文件
