反向代理

反向代理 JumpServer 要求说明

  • rdp 协议复制粘贴需要部署可信任的 ssl 证书
  • 通过 https 协议访问就能在 rdp 资产里面使用复制粘贴
  • 遵循 Mozilla SSL Configuration Generator 建议

1. nginx ssl 部署

请准备好 ssl 证书

  • 将证书放到 /opt/jumpserver/config/nginx/cert 里面

vi /opt/jumpserver/config/config.txt

...

## Nginx 配置，这个 Nginx 是用来分发路径到不同的服务
HTTP_PORT=8080
HTTPS_PORT=8443
SSH_PORT=2222

## LB 配置, 这个 Nginx 是 HA 时可以启动负载均衡到不同的主机
USE_LB=1                   # 启用 LB
LB_HTTP_PORT=80            # 启用 80   端口(http)
LB_HTTPS_PORT=443          # 启用 443  端口(https)
LB_SSH_PORT=2223           # 启用 2223 端口(ssh)

vi /opt/jumpserver/config/nginx/lb_http_server.conf

# Todo: May be can auto discovery
upstream http_server {
  sticky name=jms_route;
  server nginx:80;
  # server HOST2:8080;  # 多节点
}

server {
  listen 80;
  server_name demo.jumpserver.org;  # 自行修改成你自己的域名
  return 301 https://$server_name$request_uri;
}

server {
  listen 443 ssl;
  server_name demo.jumpserver.org;      # 自行修改成你自己的域名
  server_tokens off;
  ssl_certificate cert/server.crt;      # 修改成你自己的证书
  ssl_certificate_key cert/server.key;  # 修改成你自己的证书
  ssl_session_timeout 1d;
  ssl_session_cache shared:MozSSL:10m;
  ssl_session_tickets off;
  ssl_protocols TLSv1.1 TLSv1.2;

  ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
  ssl_prefer_server_ciphers off;
  add_header Strict-Transport-Security "max-age=63072000" always;

  client_max_body_size 5000m;  # 上传文件大小限制

  location / {
    proxy_pass http://http_server;
    proxy_buffering off;
    proxy_request_buffering off;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;

    proxy_ignore_client_abort on;
    proxy_connect_timeout 600;
    proxy_send_timeout 600;
    proxy_read_timeout 600;
    send_timeout 6000;
  }
}

./jmsctl.sh restart

2. 多层 nginx 反向代理

  • 适合上层还有统一对外出口的反向代理服务器
  • 属于多层 nginx 反向代理
  • 每一层都需要设置 websocket 长连接

vi /etc/nginx/conf.d/jumpserver.conf

server {

    listen 80;
    server_name demo.jumpserver.org;  # 自行修改成你的域名

    client_max_body_size 4096m;  # 上传文件大小限制

    location / {
            # 这里的 ip 是后端 JumpServer nginx 的 ip
            proxy_pass http://192.168.244.144;
            proxy_http_version 1.1;
            proxy_buffering off;
            proxy_request_buffering off;
            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;
    }
}

推荐部署 ssl 使用更安全的 https 协议访问

server {
    listen 80;
    server_name demo.jumpserver.org;  # 自行修改成你的域名
    return 301 https://$server_name$request_uri;
}
server {
    listen 443 ssl;
    server_name          demo.jumpserver.org;  # 自行修改成你的域名
    ssl_certificate      sslkey/1_jumpserver.org_bundle.crt;  # 自行设置证书
    ssl_certificate_key  sslkey/2_jumpserver.org_bundle.key;  # 自行设置证书
    ssl_session_timeout 1d;
    ssl_session_cache shared:MozSSL:10m;
    ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
    ssl_prefer_server_ciphers off;
    ssl_protocols TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers off;
    add_header Strict-Transport-Security "max-age=63072000" always;

    client_max_body_size 4096m;  # 录像及文件上传大小限制
    location / {
        # 这里的 ip 是后端 JumpServer nginx 的 ip
        proxy_pass http://192.168.244.144;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_request_buffering off;
        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;
    }
}

3. 其他 slb

  • 需要注意 websocket 长连接设置即可
  • 需要注意 session 问题
