客运过程已经开始了？但事实并非如此

Question

尝试独立启动乘客passenger start -p 80并且它说它已经在运行但是当我做了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. 但它显然不是因为当我尝试停止它时它说它没有运行而我无法从网络访问它

[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

Answer 1

尝试运行lsof或netstat -tlnp | grep 80确定哪个应用程序正在使用端口80.一旦你弄清楚你可以做像ps -elf这样的事情来杀死那个进程.
