Jetty server stops running after closing terminal window
提问by einstein
I am a newbie when it comes to Java and Jetty app deployment. I use the default settings for setting up my jetty serve and ran java -jar start.jaron my terminal window. The server runs as expected, but when I close my terminal it stops. Is this normal? I used XAMPP before and there you can close the terminal without any problem. How do I overcome this problem, everybody needs to shut down there personal computer once in a while.
我是 Java 和 Jetty 应用程序部署的新手。我使用默认设置来设置我的码头服务并java -jar start.jar在我的终端窗口上运行。服务器按预期运行，但是当我关闭终端时它停止了。这是正常的吗？我之前使用过 XAMPP，在那里您可以毫无问题地关闭终端。我如何克服这个问题，每个人都需要偶尔关闭个人电脑。
I'm using a mac btw.
顺便说一句，我正在使用 mac。

It sounds like you're using ssh or something like that to start Jetty on a remote Linux/Unix server.
听起来您正在使用 ssh 或类似方法在远程 Linux/Unix 服务器上启动 Jetty。
So, you can use nohup java -jar start.jar &- nohupwill prevent your process from being stopped by the usual Unix "hangup" signal (ref) when you log out, and the &will put jetty as a background process so you can type exitor whatever to log out.
因此，您可以使用nohup java -jar start.jar &-nohup将防止您的进程在您注销时被通常的 Unix“挂断”信号（ref）停止，并且&将码头作为后台进程，以便您可以键入exit或注销。
If you want to be able to re-attach to the Jetty terminal, I'd recommend reading up on GNU screen.
如果您希望能够重新连接到 Jetty 终端，我建议您阅读GNU screen。
If you want to stop jetty gracefully again, I'd really recommend using it as a service, or using screento avoid losing the terminal. But if it's too late for that you can find the PID in the output of jps -land then call kill $PID.
如果您想再次优雅地停止码头，我真的建议将其用作服务，或者使用screen以避免丢失终端。但是，如果为时已晚，您可以在 的输出中找到 PID jps -l，然后调用kill $PID.

try "nohup java -jar start.jar &"
尝试“nohup java -jar start.jar &”
and i'm already say it in previous question )
我已经在上一个问题中说过了）

How to kill process:
如何杀死进程：
1) java style
1）Java风格
when start jetty :
启动码头时：
java -DSTOP.PORT=8077 -DSTOP.KEY=secret_key_only_admin_know -jar start.jar
java -DSTOP.PORT=8077 -DSTOP.KEY=secret_key_only_admin_know -jar start.jar
for stop:
停止：
java -DSTOP.PORT=8077 -DSTOP.KEY=secret_key_only_admin_know -jar start.jar -stop
java -DSTOP.PORT=8077 -DSTOP.KEY=secret_key_only_admin_know -jar start.jar -stop
P.S. ports can be any - but they must be the same for start and kill commands :)
PS 端口可以是任何 - 但它们对于启动和终止命令必须相同:)

You can properly install it as a linux service(if you are actually connecting to a linux server) too.
您也可以将其正确安装为 linux 服务（如果您实际上是连接到 linux 服务器）。
cd to your jetty folder, for example mine is:
cd 到您的码头文件夹，例如我的是：
cd /home/spydon/jetty/
They have actually made most of the work with the jetty.sh file, so copy that one to /etc/init.d/
他们实际上已经使用 jetty.sh 文件完成了大部分工作，因此将其复制到 /etc/init.d/
sudo cp ./bin/jetty.sh /etc/init.d/jetty
Then open the file with your favorite text editor, like vim or nano
然后用你最喜欢的文本编辑器打开文件，比如 vim 或 nano
sudo vim /etc/init.d/jetty
In the beginning simply uncomment(simply remove the hash(#)) three lines that says something like
一开始简单地取消注释（简单地删除哈希（#））三行，上面写着类似的东西
#chkconfig: 3 99 99
#description: Jetty 9 webserver
#processname: jetty
Meanwhile you have the text editor open, also add the jetty home directory to the beginning of the file, mine looks like this:
同时打开文本编辑器，将 jetty 主目录添加到文件的开头，我的看起来像这样：
#!/usr/bin/env bash
#
# Startup script for jetty under *nix systems (it works under NT/cygwin too).
JETTY_HOME=/home/spydon/jetty
# To get the service to restart correctly on reboot, uncomment below (3 lines):
# ========================
chkconfig: 3 99 99
description: Jetty 9 webserver
processname: jetty
# ========================
(You don't actually need to uncomment those three lines for it to work, only add the jetty_home. But for a proper deploy you should probably fix those lines.)
（您实际上不需要取消注释这三行即可使其工作，只需添加 jetty_home。但为了正确部署，您可能应该修复这些行。）
Now you should be able to start it with
现在你应该可以开始了
sudo /etc/init.d/jetty start
And if you want it to run every time you boot, simply add
如果您希望它每次启动时都运行，只需添加
sudo ln -s /etc/init.d/jetty /etc/rc1.d/K99jetty
sudo ln -s /etc/init.d/jetty /etc/rc2.d/S99jetty
This should work for most modern distros, but I've only tried it on debian based ones.
这应该适用于大多数现代发行版，但我只在基于 debian 的发行版上尝试过。
