如何在厨师食谱的背景下运行java程序
我是一名厨师新秀。 我想创建一个在后台运行jar的配方。
bash 'run_jar' do code <<-EOH wget https://github.com/kiwiwin/jar-repo/releases/download/kiwi/helloworld-1.0.jar -O hello.jar java -jar hello.jar & EOH end helloworld-1.0.jar是程序首先打印“Hello World”，然后执行while（true）循环。
我希望当我登录到厨师 – 客户端机器时。 它应该表明有一个使用“jps”命令运行的jar。 但是没有这样的jar子运行。
我可以看到下载了hello.jar，表明代码块已经被执行了。
这个食谱有什么问题？
建议您将代码配置为作为服务运行。 有几个包装器，例如：
完成此操作后，您可以配置chef来管理新服务：
service "myapp_service" do supports :status => true, :restart => true start_command "/usr/lib/myapp/bin/myapp start" restart_command "/usr/lib/myapp/bin/myapp restart" status_command "/usr/lib/myapp/bin/myapp status" action [ :enable, :start ] end
您应该使用remote_file资源来获取文件，而不是在bash here文档块中使用wget 。
调试非常有用，如果你不确定就启用它;-)（假设你正在使用chef-solo）
chef-solo -c solo.rb -j node.json -l debug
注意：我建议将文件下载到
Chef::Config[:file_cache_path]或/tmp。
我能够使用remote_file实现你想要的。 配方如下所示：
temp=Chef::Config[:file_cache_path] remote_file "#{Chef::Config[:file_cache_path]}/hello.jar" do source "https://github.com/kiwiwin/jar-repo/releases/download/kiwi/helloworld-1.0.jar" mode 00644 end bash 'run_jar' do code <<-EOF /opt/jdk1.6.0_37/bin/java -jar #{temp}/hello.jar > #{temp}/hello.log 2>&1 & EOF end
示例在EC2测试盒上运行（性能糟透……）：

我认为最好使用像主管这样的工具。 我正在使用poise supervisor配方，你可以在这里阅读它。
这是一个示例代码：
include_recipe "supervisor" service "supervisor" do supports :status => true, :restart => true action [:enable, :start] end # configure supervisor supervisor_service "sample-java-app" do command "java -jar hello.jar" directory environment action [:enable, :start] autostart true autorestart true stdout_logfile /var/log/sample-java-app.log redirect_stderr true user root notifies :restart, 'service[supervisor]', :delayed end
您可以使用以下命令控制您的服务：
$> supervisorctl start/stop/restart sample-java-app
