所以当浏览127.0.0.1:9160，它显示空白页。但除了按下Ctrl+c并停止卡桑德拉之外，我无法使用此终端窗口。

我在寻找是否可以使用./bin/cassandra -f &返回终端窗口，但尝试pgrep thrift或pgrep cassandra时，我什么也没找到。我不知道如何使用其他终端窗口时如何停止它

-f用于前景。如果你想让Cassandra守护神，就省略它。

在* nix系统上，您应该能够键入ctrl-z以暂停前台cassandra进程。这会给你一个提示，如果你在提示符后键入bg，cassandra进程将会后台运行。您可以使用任何需要背景的前台进程执行此操作。

，如果你使用的组合-f和&那么你的工作是在后台。

你可以输入：

fg

将其带回前台，然后CTRL-C

或使用：

jobs

，看看你有什么背景。那么你可以使用fg和工作号码。

您还可以使用CTRL-Z暂停无论是在终端上当前正在运行，然后使用：

bg

背景吧。

这里就是我跑尾两次，证明把它和关闭终端

使用

./cassandra -f pid.txt

为例会话你进程将自动在后台运行，并将进程ID推入文件。使用pid.txt中的进程ID停止cassandra进程会很有帮助。

对于Windows ....您需要重新启动集群，因为一旦服务在前台运行，集群将需要重新启动
