我想用monit来监控 rabbitmq的进程，但无法启动

Question

我想用monit来监控 rabbitmq的进程 我的monitrc 里添加的配置是这样的

check process rabbitmq
  with pidfile "/var/lib/rabbitmq/mnesia/rabbit@Ct-OS63.pid"
  start program = "/usr/local/rabbitmq/sbin/rabbitmq-server" as uid root and gid root
  stop program = "/usr/local/rabbitmq/sbin/rabbitmqctl stop"

但是， 我用 monit 的start 命令怎么都启动不了进程，不知道是怎么回事，哪位大神能帮忙看下
