• 复制服务启动文件

  cp ~/ganglia-3.6.0/gmond/gmond.init /etc/rc.d/init.d/gmond
  cp ~/ganglia-3.6.0/gmetad/gmetad.init /etc/rc.d/init.d/gmetad
  
  chkconfig --add gmond
  chkconfig --add gmetad
  chkconfig gmond on
  chkconfig gmetad on

• 修改配置文件

  vi /etc/init.d/gmond
  
  GMOND=/usr/local/ganglia-3.6.0/sbin/gmond
  daemon $GMETAD -c /etc/ganglia/gmond.conf
  
  vi /etc/init.d/gmetad
  
  GMETAD=/usr/local/ganglia-3.6.0/sbin/gmetad
  daemon $GMOND -c /etc/ganglia/gmetad.conf

  }
  
  udp_send_channel {
  	host = ganglia.monitor
  	port = 8649
  	ttl = 1
  }
  
  udp_recv_channel {
  	port = 8649
  }
  tcp_accept_channel {
  	port = 8649
  }
