TCP转发

使用Nginx转发

stream {
   upstream backends {
        server 10.0.0.10:80;
        server 10.0.0.11:80;
        server 10.0.0.12:80  backup;
   }
   server  {
        listen 80;
        proxy_pass backends;
   }
}

使用Haproxy转发

listen tcp-80
    mode tcp
    bind *:80 
    server srv1 10.0.0.10:80 check
    server srv2 10.0.0.11:80 check
    server srv3 10.0.0.12:80 check backup
