ubuntu/mac 设置nginx反向代理3000端口

nginx的配置文件在 /etc/nginx/nginx.conf

怎么安装nginx 这里就不赘述了 可以brew安装

或者在conf.d中新建一个demo.conf

写入以下内容

#本地http-server开启的server，命名为node-server，监听3000和3001端口
upstream node-server{
# weight表示权重，数值越大，表示被分配到这个server的几率越大，这里我们让其相等。
    server 127.0.0.1:3000 weight=1;
    server 127.0.0.1:3001 weight=1;
}

# NGINX 虚拟主机，监听80端口
server {
    listen 80;
    server_name test.com;
    access_log /var/log/nginx/node-server;

    # Gzip Compression
    gzip on;
    gzip_comp_level 6;
    gzip_vary on;
    gzip_min_length  1000;
    gzip_proxied any;
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_buffers 16 8k;

    # 反向代理 node-server
    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;
      # 代理的地址
      proxy_pass http://node-server;
      proxy_redirect off;
    }
 }

重启nginx
sudo nginx -s reload
