为什么zookeeper不使用我的log4j.properties文件日志目录

时间：2014-10-28 15:58:56

标签： linux apache log4j environment-variables apache-zookeeper

在我的zookeeper / conf / log4j.properties文件中，我将zookeeper.log.dir设置为$ HOME / zklogs

当我使用zkServer.sh时，它不使用该目录。相反，它使用$ {ZOO_LOG_DIR}，当我回应它时，它出现在＆＃34;。＆＃34;

我不明白如何解决这个问题，我在任何地方都看不到$ {ZOO_LOG_DIR}。我不确定它是如何设置为＆＃34;。＆＃34;一点都不我也不知道如何在没有zkServer.sh的情况下启动zookeeper。我在linux上也很吵，在这个问题上有点迷失......

有人知道如何解决这个问题，以便它使用conf目录中我的log4j.properties文件中设置的目录吗？

***更新，我在我的zookeeper安装的bin目录中的zkEnv.sh中找到了。有代码：

if["x${ZOO_LOG_DIR}" = "x" ]
then
   ZOO_LOG_DIR="."
fi

我不确定第一行发生了什么，但必须在这里出现问题。我希望它从我的log4j.properties文件中查看zookeeper.log.dir。任何人都可以告诉我这是否属实？我不想在这里艰难地走这条路......

答案 0 :(得分：38)

我想添加如何解决此问题/自定义我的环境。

这里有2种日志记录机制：

  • bin / zkServer.sh将zookeeper服务器的stdout和stderr重定向到zookeeper.out
  • log4j可以将日志追加到多个地方，包括：
    • CONSOLE - 最终出现在zookeeper服务器的stdout和stderr
      • 中
    • ROLLINGFILE - 发送到zookeeper.log

bin / zkServer.sh使用：

  • ZOO_LOG_DIR设置zookeeper.out和log4j的路径。
  • ZOO_LOG4J_PROP设置log4j日志记录级别以及启用了哪些日志追加程序

＆＃34;最终＆＃34; setup conf / log4j.properties中的默认值由zookeeper bash脚本的组合设置：

  • ZOO_LOG_DIR =。 （启动zookeeper的工作目录）
    • 在conf / log4j.properties中设置为zookeeper.log.dir
  • ZOO_LOG4J_PROP = INFO，CONSOLE
    • 在conf / log4j.properties中设置为zookeeper.root.logger

打开日志追加器CONSOLE的效果是日志现在转到stdout。因为bin / zkServer.sh将stdout和stderr重定向到zookeeper.out，所以log4j日志最终会出现在zookeeper.out中。关闭ROLLINGFILE的效果是没有创建zookeeper.log文件。

不会轮换zookeeper.out日志。 zookeeper.log日志设置为旋转，可以设置为使旧日志过期。

我希望日志滚动并过期。我要做的第一件事是更改conf / log4j.properties以导致旧日志的到期/删除。我通过在conf / log4j.properties中设置log4j.appender.ROLLINGFILE.MaxBackupIndex来做到这一点。我要做的第二件事是设置日志目录，日志记录级别和追加者。

我有一个每分钟运行一次的bash脚本。如果它看到zookeeper没有运行，它会运行：

bin/zkServer.sh start

我将其更改为指定bin / zkServer.sh期望的环境变量。

sudo ZOO_LOG_DIR=/opt/zookeeper-3.4.6/logs ZOO_LOG4J_PROP='INFO,ROLLINGFILE' /opt/zookeeper-3.4.6/bin/zkServer.sh start

关闭日志追加器CONSOLE的效果是log4j日志现在不再以zookeeper.out结尾。打开ROLLINGFILE的效果是zookeeper.log文件被创建，旋转和过期。

BTW，conf / log4j.properties显然已经在我的类路径中了。在这方面我不得不做任何改变。

答案 1 :(得分：6)

zkServer.sh从zkEnv.sh获取环境变量 env文件设置一个类路径，如果它位于预期的位置，则包含log4j文件。

ZOOXFGDIR=ZOOBINDIR/../conf

我将一些回声放入zkServer.sh以追踪正在发生的事情。 我发现正确设置了classpath，但是没有设置logdir和log4j_prop。所以我将它们添加到zkEnv.sh。现在，日志似乎显示在预期的位置。

ZOO_LOG_DIR="/var/log/zookeeper"
ZOO_LOG4J_PROP="INFO,ROLLINGFILE"

答案 2 :(得分：2)

据我所知，zkEnv.sh zookeeper / conf文件夹已经在classpath中。那里有两个问题：

  1. zkServer.sh添加＆＃34; -Dzookeeper.log.dir =。＆＃34;除非指定ZOO_LOG_DIR环境变量
    2. ，否则转到ZK启动命令

  2. 即使你确实指定了ZOO_LOG_DIR，ZK仍然无法找到你的log4j.properties文件，因为zkEnv.sh指定了这样的CLASSPATH：

    $CLASSPATH="$ZOOCFGDIR:$CLASSPATH"

    3. 如果$ CLASSPATH环境变量不为空，这可以正常工作，但是当它为空时，它只会留下一个尾随冒号，这会搞砸你的类路径。 我将上面的行改为：

    #add the zoocfg dir to classpath
if [ "x${CLASSPATH}" = "x" ]
then
    CLASSPATH="$ZOOCFGDIR"
else
    CLASSPATH="$ZOOCFGDIR:$CLASSPATH"
fi

    并且还为ZK传递了ZOO_LOG_DIR环境，因为zkServer.sh在启动ZK时生成-Dzookeeper.log.dir VM参数。这是为我启动ZooKeeper的命令，使其读取/opt/zookeeper/conf/log4j.properties并将日志文件保存在/ opt / zimbra / log中：

    ZOO_LOG_DIR=/opt/zimbra/log /opt/zookeeper/bin/zkServer.sh start

答案 3 :(得分：1)

我相信我的问题的答案是我需要将log4j.properties文件移动到我的类路径中，然后只有当我调用zkServer.sh时zkEnv.sh将读取我在log4j.properties中设置的值。我相信我只是不明白如何正确使用log4j。

答案 4 :(得分：1)

通过ZOO_LOG_DIR环境变量更改文件日志目录的另一个选项是创建自己的zk-server-1 / conf / zookeeper-env.sh。

阅读zookeeper-3.4.6 dist bash脚本（t.i。zkEnv.sh），他们会找到zookeeper-env.sh文件（如果存在）。这是它（我创建的）内容：

export ZOO_HOME=$ZOOKEEPER_PREFIX
echo $ZOO_HOME
export ZOO_LOG_DIR=$ZOO_HOME/logs

我习惯拥有 PRODUCTNAME _HOME变量，该变量指向zookeeper的顶级安装目录。这个顶级目录似乎被zookeeper dist命名为$ ZOOKEEPER_PREFIX，我将其与$ ZOO_HOME联系并将其用于ZOO_LOG_DIR环境变量。

在这篇文章的最后，我假设了bash脚本调试信息 - 帮助我调查使用哪个环境或局部变量加上值。

正如我所看到的，/ home / joma / dev / programme / zk-local-feel / zk-server-1 / bin / .. / dir是在CLASSPATH上，因此log4j.properties文件符合条件通过java的log4j框架的类加载器来加载资源（这是log4j实现AFAIR的方式）。

也许不是寻求的答案，但对于conf目录中的zookeeper-3.4.11，您可以在log4j.properties文件中设置适当的级别和配置
