nginx 的几种用法

1、反向代理

server {
     listen 80;
     server_name  test.com;
     location  / {
         proxy_pass http://172.10.110.100:8080;
         proxy_set_header Host $host;
     }
    }

2、springboot + vue 反向代理

  # 支持 websocket 设置一个变量
     map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }

    upstream test_prod {
        fair;
        server 192.168.1.101:24035;
        server 192.168.1.102:24035;
    }

    # 域名跳转
    server {
        listen 80;
        server_name    test.cn;
        rewrite "^/(.*)$" http://test.com/$1;
    }

    # 正向代理 test.com
    server {
        listen 80;
        server_name    test.com;
        access_log      /export/servers/nginx/logs/test.com_access.log;
        error_log      /export/servers/nginx/logs/test.com_error.log;

        # vue 静态资源走本地
        location / {
                root   /home/admin/apps/appName/dist/;
                index  index.html;
        }

        #  图片资源走图片服务，这里仅仅是域名替换
        location ~ ^/(image)/\.* {
            rewrite ^/(.*) /$1 break;
            proxy_pass http://image.com;
        }

        # 后端服务的uri前缀是v1的走后端服务 
        location  ~^/(v1) {
                proxy_pass   http://test_prod;
                proxy_set_header Host $host;
                
                # 支持 websoket 使用变量
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
           }
    }
