这很糟糕:
$ thin restart -p 4000 -s 3 -d;
Stopping server on 0.0.0.0:4000 ...
Sending QUIT signal to process 13375 ...
>> Exiting!
Stopping server on 0.0.0.0:4001 ...
Sending QUIT signal to process 13385 ...
>> Exiting!
Stopping server on 0.0.0.0:4002 ...
Sending QUIT signal to process 13397 ...
>> Exiting!
Starting server on 0.0.0.0:4000 ...
Starting server on 0.0.0.0:4001 ...
Starting server on 0.0.0.0:4002 ...
有没有办法循环通过每台服务器并一次重新启动一个?
