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

在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\u LOG\u DIR}，当我回显它时，它会显示为“.”

我不知道如何解决这个问题，我没有看到${ZOO\u LOG\u DIR}设置在任何地方。我根本不知道它是如何被设置为“.”。我也不知道在没有zkServer.sh的情况下如何启动zookeeper。我对linux也不了解，在这个问题上有点迷茫

有人知道我如何解决这个问题，以便它使用conf目录下log4j.properties文件中设置的目录吗

***更新，我在zookeeper安装的bin目录中的zkEnv.sh中找到。代码如下：

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

---

我不确定第一行发生了什么，但一定是这里出了问题。我希望它从log4j.properties文件中查看zookeeper.log.dir。有人能告诉我这是不是真的吗？我不想在这里硬连接路径…

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，只有这样，当我调用zkServer.sh时，zkEnv.sh才会读取我在log4j.properties中设置的值。我相信我只是不理解如何正确使用log4j。

从zkEnv.sh zookeeper/conf文件夹中可以看到，它已经在类路径中了。这里有两个问题：

zkServer.sh将“-Dzookeeper.log.dir=”添加到ZK启动命令中，除非您指定了ZOO_log_dir环境变量

即使指定了ZOO_LOG_DIR，ZK也可能无法找到log4j.properties文件，因为zkEnv.sh指定的类路径如下：

$CLASSPATH=“$ZOOCFGDIR:$CLASSPATH”

如果$CLASSPATH环境变量不是空的，那么这很好，但是当它为空时，只会留下一个尾随冒号，这会破坏类路径。 我将上面的行更改为：

#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。下面是为我启动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

---

我想补充我是如何解决这个问题/定制我的环境的

这里有两种日志记录机制：

• bin/zkServer.sh将zookeeper服务器的stdout和stderr重定向到zookeeper.out
• log4j可以将日志附加到多个位置，包括：
  • 控制台-最终出现在zookeeper服务器的标准输出和标准输出中
  • 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_道具，用于设置LOG4J日志记录级别以及打开哪些日志附加器

setup conf/log4j.properties中的“最终”默认值由zookeeper bash脚本组合设置：

• 动物园日志目录=。（启动zookeeper的工作目录）
  • 将conf/log4j.properties的内部设置为zookeeper.log.dir
• ZOO_LOG4J_道具=信息，控制台
  • 将conf/log4j.properties的内部设置为zookeeper.root.logger

打开LogAppender控制台的效果是日志现在转到标准输出。因为bin/zkServer.sh将stdout和stderr重定向到zookeeper.out，所以log4j日志最终位于zookeeper.out中。关闭ROLLINGFILE的效果是不会创建zookeeper.log文件

zookeeper.out日志未旋转。zookeeper.log日志设置为旋转，并可设置为使旧日志过期

我希望日志滚动并过期。我必须做的第一件事是更改conf/log4j.properties以导致旧日志过期/删除。我是通过在conf/log4j.properties中设置log4j.appender.ROLLINGFILE.MaxBackupIndex来实现的。我必须做的第二件事是设置日志目录、日志级别和appender

我有一个每分钟运行的bash脚本。如果它看到zookeeper没有运行，它将运行：

bin/zkServer.sh start

我将其更改为指定bin/zkServer.sh所期望的环境变量

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log appender控制台的效果是log4j日志现在不再显示在zookeeper.out中。启用ROLLINGFILE的效果是创建、旋转zookeeper.log文件并使其过期

顺便说一句，conf/log4j.properties显然已经在我的类路径中了。在这方面我不需要做任何改变

这条链条大大有助于我理解：

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）的来源。以下是它的（我创建的）内容：

我习惯于使用PRODUCTNAME\U HOME变量，它指向zookeeper的顶部安装目录。这个顶级目录似乎被ZOOKEEPER dist命名为$ZOOKEEPER\u PREFIX，我用$ZOO\u HOME作为别名，并将其用于ZOO\u LOG\u dir环境变量

在这篇文章的最后，我整理了bash脚本调试信息——帮助我调查使用了哪些环境或局部变量加值

在我看来，/home/joma/dev/program/zk local emblem/zk-server-1/bin/./conf dir位于类路径上，因此log4j.properties文件可以通过java的log4j框架类加载器进行资源加载（这是log4j的AFAIR实现方式）

zkServer.sh

从

zkEnv.sh

env文件设置一个类路径，其中包括log4j文件（如果它位于预期位置）

ZOOXFGDIR=ZOOBINDIR/。/conf

我在zkServer.sh中放了一些回音来跟踪发生了什么。 我发现classpath正在运行

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