nginx为流程软件和pmp两个软件代理

[shj8024]

场景：
两台服务器
192.168.1.1 安装oa 192.168.1.1可以直接访问oa
192.168.1.2 安装pmp 192.168.1.2可以直接访问pmp
单独访问都可以
增加一台服务器 192.168.1.3 安装ngnx，做反向代理，
应该怎么配置，
需要用到upstream吗？
谢谢各位大神了

如果你想要做负载均衡,要用到upstream, 那就是这样的:

upstream proxy_servers {
  server 192.168.1.1 weight=5;
  server 192.168.1.2 weight=5;
}
server {
    listen 80 default_server;
    server_name _;
    location / {
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://proxy_servers;
    }
}

如果你想做反向代理,那就是这样的:

server {
    listen 80;
    server_name server1_domain.com;
    location / {
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://192.168.1.1;
    }
}
server {
    listen 80;
    server_name server2_domain.com;
    location / {
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://192.168.1.2;
    }
}
