今天配置nginx https 反向代理 居然出现502 bad gateway， 原来是selinux的问题，汗~~

nginx配置文件

upstream test{
    server 127.0.0.1:8082;
  }

  server{

	listen 443 ssl;
	ssl_certificate www.example.com.crt;
	ssl_certificate_key www.example.com.key;

	server_name     www.example.com;

	server_tokens	off;
      
    location  / {
	proxy_set_header Host $host;
	proxy_set_header X-Real-IP $remote_addr;
	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_pass    http://test/;
    }

  }

启动nginx，放地址居然是502 bad gateway

查看了nginx错误日志,居然是Permission denied

2020/07/16 14:37:54 [crit] 27257#27257: *33 connect() to 127.0.0.1:8082 failed (13: Permission denied) while connecting to upstream, client: 192.168.101.106, server: www.example.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8082/", host: "www.example.com"

网上查了原来是SELinux的原因

把它关掉算了
