无法让码头使用 logback 进行日志记录

Question

我跟随 this page 在我的 Amazon EC2 实例（Ubuntu 14.04.2 LTS）上安装了码头。码头正在运行。但是，我不能让它使用 logback 进行日志记录。以下是相关信息。我在这里做错了什么？

Answer 1

首先（也是最重要的）不要在${jetty.home} 中更改、编辑、修改、添加、删除、删除、破坏、重命名、触摸等任何内容

那是你的 jetty-distribution 目录，它不打算改变，解压它，然后不管它。

它甚至会在您启动时告诉您这一点！

2015-05-06 06:34:58.838:WARN:oejs.HomeBaseWarning:main: This instance of Jetty is not
running from a separate {jetty.base} directory, this is not recommended.  
See documentation at http://www.eclipse.org/jetty/documentation/current/startup.html
2015-05-06 06:34:58.959:INFO:oejs.Server:main: jetty-9.2.10.v20150310

要解决这个问题：

首先在某处（任何地方）创建一个新目录，这将成为您的${jetty.base}

${jetty.base} 目录是您配置正在运行的 Jetty 实例的位置。

该文档在${jetty.base} 中有关于 3 种不同的 logback 配置的说明

• Just Logback
• Capturing all logging events on the server side from log4j, commons-logging, slf4j, jetty log, and java.util.logging and routing them to Logback
• Forcing centralized logging of all logging, even those produced in webapps, to a single logback configuration

如果你遵循这些指示，你会得到：

• ${jetty.base} 为您提供 start.ini
• ${jetty.base}/lib/logging 中您需要的库
• 一个被覆盖的${jetty.base}/modules/logging.mod
• ${jetty.base}/resources/logback.xml中的logback配置
• ${jetty.base}/resources/jetty-logging.properties 中的码头日志记录配置

从这里开始，您可以在 ${jetty.base}/start.ini 中设置您需要的其余模块，以及您需要的 web 应用程序和其他零碎（永远不要编辑 ${jetty.home}）

最后，您将编辑 /etc/default/jetty 以添加指向此目录的 JETTY_BASE。

要测试此${jetty.base} 配置是否有意义，您将使用命令行。

CD 进入你的新${jetty.base} 并运行

[mybase]$ java -jar /path/to/jetty-dist/start.jar

这会将配置作为正常进程（而不是服务）启动，您可以从中查看配置是否按照您需要的方式运行。

Answer 2

我按照官方的例子解决了这个问题：http://eclipse.org/jetty/documentation/current/example-logging-logback-centralized.html。实际步骤与 Joakim 在他的回答中提到的非常相似。

这些基本上是我使用的命令：

[base]$ mkdir modules
[base]$ cd modules
[modules]$ curl -O https://raw.githubusercontent.com/jetty-project/logging-modules/master/capture-all/logging.mod
[modules]$ curl -O https://raw.githubusercontent.com/jetty-project/logging-modules/master/centralized/webapp-logging.mod
[modules]$ cd ..
[base]$ java -jar /opt/jetty/start.jar --add-to-start=logging,webapp-logging

Answer 3

运行以下命令，Jetty 做所有事情：

[my-base]$ java -jar ../start.jar --add-to-start=logging-logback
