试图启动客运独立与passenger start -p 80 ，它说它已经运行，但是当我做一个passenger stop -p 80我得到According to the PID file '/var/crm/tmp/pids/passenger.80.pid', Phusion Passenger Standalone doesn't seem to be running. 但显然不是因为当我试图阻止它，它说它没有运行，我不能从networking上访问它
[root@technetium crm]# passenger start -p 80 *** ERROR *** The address 0.0.0.0:80 is already in use by another process, perhaps another Phusion Passenger Standalone instance. If you want to run this Phusion Passenger Standalone instance on another port, use the -p option, like this: passenger start -p 81
尝试运行lsof或netstat -tlnp | grep 80 netstat -tlnp | grep 80来确定哪个应用程序正在使用端口80.一旦你知道了，你可以做一些像ps -elf来杀死这个进程。
