rabbitmq安装报错"undefined function rabbitmqctl_escript:main/1"

[root@localhost sbin]# rabbitmqctl status
escript: exception error: undefined function rabbitmqctl_escript:main/1
  in function  escript:run/2 (escript.erl, line 758)
  in call from escript:start/1 (escript.erl, line 277)
  in call from init:start_em/1 
  in call from init:do_boot/3
  
解决：ln -sv /usr/local/src/rabbitmq_server-3.7.9 rabbitmq时rabbitmq_server-3.7.9后面一定不要带/，去掉即可
