code> 127.0.0.1:9160 ，它显示空白的白页。但我不能使用此终端窗口，除非按 Ctrl + c 并停止cassandra。

so when browse 127.0.0.1:9160, it shows blank white page. but I cannot use this terminal window except pressing Ctrl+c and stop cassandra.

可以使用 ./ bin / cassandra -f& 返回终端窗口，但是当尝试 pgrep thrift pgrep cassandra ，我什么也找不到。我不知道如何在使用其他终端窗口时停止它。

I'm looking if I can use ./bin/cassandra -f & to have back the terminal window, but when trying pgrep thrift or pgrep cassandra, I found nothing. I dont know how to stop it when using other terminal window

推荐答案

只要省略它，如果你想Cassandra守护进程。

The -f is for foreground. Just omit it, if you want Cassandra to daemonize.
