windows - 在 Windows 上关闭 NiFi

Question

是否有一种简单的编程方式可以在 Windows 上关闭 NiFi？ “手动”方式有效，在命令窗口中运行并按 ctr-c 退出，但我正在尝试自动化测试环境。我可以在 linux 上使用 nifi.sh 脚本，我在谷歌搜索时看到了对关闭 bat 脚本的引用，但我使用的是 0.6.1，但它不在那个版本中。

我使用 netstat 根据 API 端口号查找 PID，然后终止该进程。但似乎总是有两个进程，一个将重新启动另一个。所以我做了同样的事情，使用 Bootstrap 端口，用它来查找进程的 PID，然后也终止该进程。但这并不总是可靠的。

您可以在 Windows 上停止 nifi。为此，您必须打开 run-nifi.bat 文件并替换 run 以在文件中停止。

然后将文件另存为nifi-stop.bat

所以 nifi-stop.bat 的内容将如下所示。

@echo off

rem Set environment variables

call %~sdp0\nifi-env.bat

rem Use JAVA_HOME if it's set; otherwise, just use java

if "%JAVA_HOME%" == "" goto noJavaHome
if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome
set JAVA_EXE=%JAVA_HOME%\bin\java.exe
goto startNifi

:noJavaHome
echo The JAVA_HOME environment variable is not defined correctly.
echo Instead the PATH will be used to find the java executable.
echo.
set JAVA_EXE=java
goto startNifi

:startNifi
pushd "%NIFI_ROOT%"
set LIB_DIR=lib\bootstrap
set CONF_DIR=conf

set BOOTSTRAP_CONF_FILE=%CONF_DIR%\bootstrap.conf
set JAVA_ARGS=-Dorg.apache.nifi.bootstrap.config.log.dir=%NIFI_LOG_DIR% -Dorg.apache.nifi.bootstrap.config.pid.dir=%NIFI_PID_DIR% -Dorg.apache.nifi.bootstrap.config.file=%BOOTSTRAP_CONF_FILE%

SET JAVA_PARAMS=-cp %CONF_DIR%;%LIB_DIR%\* -Xms12m -Xmx24m %JAVA_ARGS% org.apache.nifi.bootstrap.RunNiFi
set BOOTSTRAP_ACTION=stop

cmd.exe /C "%JAVA_EXE%" %JAVA_PARAMS% %BOOTSTRAP_ACTION%

popd

现在你可以停止nifi只运行这个文件nifi-stop.bat。
