配置nginx

Http反向代理

编辑配置

# cd /etc/nginx/conf.d
# cp default.conf  mysite.conf 

修改mysite.conf 如下:

server {
    listen  80;
    server_name 192.168.0.18;
    #access_log /var/log/nginx/pro.log;

    location  / {
         # 传递真实的请求头信息
         proxy_set_header Host $host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         # 限制文件大小为1G 
         client_max_body_size    1024m; 
         # 指定代理服务器
         proxy_pass http://127.0.0.1:8000; 
    }

    location /static/ {
        autoindex on;
        alias /root/webapps/pro/static/; # 静态文件nginx处理
    }

    error_page 500 502 503 504  /50x.html;
    location = /50x.html {
        root html;
    }
}

Tcp反向代理

注意tcp只能代理端口

stream {
  upstream mysql {
    hash $remote_addr consistent;
    server MySQL_URL:3306 max_fails=3 fail_timeout=30s;
  }

  server {
    listen 8000;
    proxy_connect_timeout 30s;
    proxy_timeout 600s;
    proxy_pass mysql;
  }
}
