+## How to support multiple ports in http and https listen port？
+
+The Apache APISIX listens to a single port by default. If you need to support http or https to listen to multiple ports, modify the steps:
+1. Modify the parameter of http port listen `node_listen`, or https port listen `ssl.listen_port` in conf/config.yaml, style like
+    ```
+    apisix:
+      node_listen:
+        - 9080
+        - 9081
+        - 9082
+      ssl:
+        listen_port:
+          - 9443
+          - 9444
+          - 9445
+    ```
+2. Restart APISIX

+## 如何支持http和https多端口监听
+apisix默认监听单端口，如果需要支持http或https监听多端口，修改步骤：
+
+1、修改conf/config.yaml中的http端口监听的配置参数`node_listen`，或https端口监听的参数`ssl.listen_port`，格式如下
+```
+apisix:
+  node_listen:
+    - 9080
+    - 9081
+    - 9082
+  ssl:
+    listen_port:
+      - 9443
+      - 9444
+      - 9445
+```
+
+2、重启APISIX
