七层反向代理

• 配置nginx.conf，在http块中添加

http {
......
    include conf.d/*.conf;
}

• 编写conf.d/your.site.com.conf

upstream backend7 {
    server 10.10.10.10:8080 max_fails=3 fail_timeout=3s;
    server 10.10.10.20:8080 max_fails=3 fail_timeout=3s;
}

server {
    listen 80;
    server_name your.site.com;

    access_log  /var/log/nginx/access-your.site.com.log  main;

    location / {
        proxy_pass http://backend7;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

四层反向代理

• 配置nginx.conf，在stream块中添加

stream {
......
    include conf.d/*.stream;
}

• 编写conf.d/your.site.com.stream

upstream backend4 {
    server 10.10.10.10:8080 max_fails=3 fail_timeout=3s;
    server 10.10.10.20:8080 max_fails=3 fail_timeout=3s;
}

server {
    listen 80;
    proxy_pass backend4;
}

生效

• 检测配置

  # nginx -t
  

• 重启

  # /etc/init.d/nginx restart
