+# 使用Nginx搭建SSL配置
+
+跳板机是所有服务器的入口，所以，它的安全至关重要。因此，建议把`Jumpserver`搭建在内网环境中，并且加上SSL证书，保证数据传输的安全。
+
+## nginx的安装
+
+不同的操作系统及版本，安装方法都不太一样。我们以`Debian`为例。
+
+```
+apt-get update
+apt-get install -y nginx
+```
+
+更多安装示例请参考 [Nginx官方安装指南](https://www.nginx.com/resources/wiki/start/topics/tutorials/install/)
+
+## Nginx中的SSL的配置
+
+* 编辑 `/etc/nginx/sites-enabled/default` 或者指定的`Jumpserver`的配置文件
+
+* 示例如下
+
+```
+server {
+  listen              443;
+  listen              80;
+  server_name         YOUR_DOMAIN;
+  ssl_certificate     YOUR_DOMAIN_CRT;
+  ssl_certificate_key YOUR_DOMAIN_KEY;
+  ssl_protocols	TLSv1 TLSv1.1 TLSv1.2;
+  ssl_ciphers	HIGH:!aNULL:!MD5;
+  ssl_prefer_server_ciphers on;
+  ssl on ;
+
+  if ($ssl_protocol = "") {
+    rewrite ^ https://$host$request_uri? permanent;
+  }
+
+  location / {
+    proxy_set_header Connection "";
+    proxy_http_version 1.1;
+    proxy_pass      http://JUMPSERVER_HOST:WEB_PORT;
+  }
+
+  location /_ws/ {
+    keepalive_timeout 600s;
+    send_timeout 600s;
+    proxy_connect_timeout 7d;
+    proxy_send_timeout 7d;
+    proxy_read_timeout 7d;
+    rewrite ^/_ws(/.*)$ $1 break;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_pass      http://JUMPSERVER_HOST:WS_PORT;
+  }
+}
+
+```
+
+* 请替换如下表格的关键字
+
+
+关键字  		 		| 示例          					| 说明
+------------- 		| -------------					|-------
+`YOUR_DOMAIN`  		|  example.com 					| `Jumpserver`的域名
+`YOUR_DOMAIN_CRT`  	| /etc/nginx/certs/example.crt	| SSL证书的CRT文件
+`YOUR_DOMAIN_KEY`  	| /etc/nginx/certs/example.key	| SSL证书的KEY文件
+`JUMPSERVER_HOST`  	| 127.0.0.1						| `Jumpserver`服务器IP
+`WEB_PORT ` 		| 80							| `Jumpserver`网页监听端口
+`WS_PORT `  		| 3000							| websocket端口，`Jumpserver` 默认为3000
+
+* 此配置会强制使用`https`, 建议加上(即if判断的那三行)。
