一个人应该如何杀死tezos节点进程？

我有几次发现自己无法重新启动tezos节点,因为我相信我已经结束了该过程,但是当我尝试再次启动它时,我收到以下消息:

Data directory is locked by another process

最近,我使用Ctrl-C,然后在看不到进度时使用Ctrl-Z.我相信这将流程置于后台,进一步加剧了我的困惑.

我应该使用哪种方法可靠地结束tezos-node进程?如果我不小心将流程放到了后台,是否有办法将其恢复到前台?
I have several times found myself unable to restart my tezos node because I believe I have ended the process but when I try to start it again I get the following message:

Data directory is locked by another process

Most recently I used Ctrl-C, then when I did not see progress, I used Ctrl-Z. I believe this put the process in the background further adding to my confusion.

What method should I use to reliably end the tezos-node process? If I accidentally put the process in the background, is there a way for me to bring it back to the foreground?

您应使用" Ctrl + c"(或杀死-15＆lt; Process-ID＆gt;)来终止tezos节点.这将花费一些时间,因为该节点尝试轻轻地取消所有计划的操作,并使数据库保持一致状态.

" Ctrl + z"(或杀死-19＆lt; Process-ID＆gt;)只是暂停该过程.您可以通过在同一终端上运行fg命令(或使用kill -18＆lt; PID＆gt;)将其恢复.

请注意,您还可以发送SIGKILL信号(kill -9＆lt; PID＆gt;),该信号将立即终止该过程.但是我不建议这样做,因为它可能会损坏数据库.

最后,您可以使用ps -A | grep tezos-node.

Your should use "Ctrl+c" (or kill -15 <Process-ID>) to terminate tezos node. This will take some time because the node tries to softly cancel all scheduled actions, and to keep the database in a consistent state.

"Ctrl+z" (or kill -19 <Process-ID>) just pauses the process. You can bring it back by running fg command in the same terminal (or with kill -18 <PID>).

Note that you can also send a SIGKILL signal (kill -9 <PID>) that will terminate the process immediately. But this is not recommended I think, as it may corrupt the database.

Finally, you can get the PID of your tezos-node process(es) with ps -A | grep tezos-node.
- 我更喜欢kill -STOP 而不是kill -19 (和kill -CONT 重新启动它).
  
  I prefer `kill -STOP ` to `kill -19 ` (and `kill -CONT ` to restart it).
