NGINX代理websocket配置

　　如题，我在100.100.6.22的8100端口启动了一个web项目，通过/live/提供http接口，通过/live/ws/提供websocket接口，进入到nginx所在目录，修改nginx.conf文件：

[sbt@wlf nginx]$ cd /usr/local/nginx
[sbt@wlf nginx]$ vi conf/nginx.conf 

　　主要新增两个location：

server {
    listen       7777;
    server_name  100.100.6.22;
    charset utf-8;
    access_log  logs/nacos.access.log  main;
    error_log   logs/nacos.error.log notice;
    index index.html; 

    location /live/ {
      proxy_pass http://100.100.6.22:8100/;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto  $scheme;
    }


    location /live/ws/ {
      proxy_pass http://100.100.6.22:8100/ws/;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_http_version  1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }
}

　　保存后重启nginx，使用root权限或者切换回root用户重启：

[sbt@wlf nginx]$ sudo ./sbin/nginx -s reload

　　跑一次websocket接口，可以看nginx日志：

[sbt@wlf nginx]$ tail -f logs/access.log
