+### 17. How to configure https after Portal is mounted to nginx/slb?
+
+1. configure https access configuration on nginx/slb, taking nginx as an example:
+
+```
+    server {
+        listen 80 default_server;
+
+        location / {
+            # redirect all requests on port 80 to https
+            return 301 https://$http_host$request_uri;
+        }
+    }
+
+     server {
+         # If the nginx version is lower and does not support http2, configure listen 443 ssl;
+         listen 443 ssl http2;
+         server_name your-domain-name;
+         # ssl certificate, nginx needs to use a certificate with a complete certificate chain
+         ssl_certificate /etc/nginx/ssl/xxx.crt;
+         ssl_certificate_key /etc/nginx/ssl/xxx.key;
+
+         location / {
+             proxy_pass http://apollo-portal-address:8070;
+             proxy_set_header x-real-ip $remote_addr;
+             proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
+             #! ! ! This must be $http_host, if it is configured as $host, the port will be wrong when redirecting
+             proxy_set_header host $http_host;
+             proxy_set_header x-forwarded-proto $scheme;
+             proxy_http_version 1.1;
+         }
+     }
+```
+
+2. Configure apollo-portal to parse the header information from the reverse proxy
+
+Modify application-github.properties under the config directory in the apollo-portal installation package and add the following configuration:
+
+```properties
+server.forward-headers-strategy=framework
+```
+
+It can also be configured through environment variables:
+
+```
+SERVER_FORWARD_HEADERS_STRATEGY=framework
+```

+### 17. Portal挂载到nginx/slb后如何配置https？
+
+1. 在nginx/slb上配置https访问配置，以nginx为例：
+
+```
+    server {
+        listen 80 default_server;
+
+        location / {
+            # 把 80 端口的请求全部都重定向到 https
+            return 301 https://$http_host$request_uri;
+        }
+    }
+
+    server {
+        # nginx 版本较低不支持 http2 的, 则配置 listen 443 ssl;
+        listen 443 ssl http2;
+        server_name  your-domain-name;
+        # ssl 证书, nginx 需要使用完整证书链的证书
+        ssl_certificate /etc/nginx/ssl/xxx.crt;
+        ssl_certificate_key /etc/nginx/ssl/xxx.key;
+
+        location / {
+            proxy_pass http://apollo-portal-address:8070;
+            proxy_set_header x-real-ip $remote_addr;
+            proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
+            # ！！！这里必须是 $http_host, 如果配置成 $host 会导致跳转的时候端口错误
+            proxy_set_header host $http_host;
+            proxy_set_header x-forwarded-proto $scheme;
+            proxy_http_version 1.1;
+        }
+    }
+```
+
+2. 配置apollo-portal解析反向代理的header信息
+
+修改apollo-portal安装包中config目录下的application-github.properties，增加以下配置：
+
+```properties
+server.forward-headers-strategy=framework
+```
+
+也可以通过环境变量配置：
+
+```
+SERVER_FORWARD_HEADERS_STRATEGY=framework
+```
