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

Question

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} ，当我回显它时，它会出现在“。”

我不明白如何解决这个问题，我在任何地方都没有看到 ${ZOO_LOG_DIR} 设置。我不确定它是如何设置为“。”一点也不。我也不知道如何在没有 zkServer.sh 的情况下启动 zookeeper。我对 linux 也很陌生，在这个问题上有点迷茫......

有人知道我该如何解决这个问题，以便它使用我在 conf 目录中的 log4j.properties 文件中设置的目录吗？

***更新，我在我的 zookeeper 安装的 bin 目录中找到了 zkEnv.sh。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，但一定是这里出了点问题。我希望它从我的 log4j.properties 文件中查看 zookeeper.log.dir。谁能告诉我这是否应该是真的？我不想在这里硬连线路径...

Answer 1

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

Answer 2

zkServer.sh 从zkEnv.sh 获取环境变量 如果 log4j 文件位于预期位置，则 env 文件会设置一个包含 log4j 文件的类路径。

ZOOXFGDIR=ZOOBINDIR/../conf

我在 zkServer.sh 中加入了一些回声来追踪发生了什么。 我发现类路径设置正确，但 logdir 和 log4j_prop 没有设置。所以我将它们添加到zkEnv.sh。日志现在似乎显示在预期位置。

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

Answer 3

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），他们获取 zookeeper-env.sh 文件（如果存在）。这是（我创建的）内容：

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

我习惯有一个 PRODUCTNAME_HOME 变量，它指向 zookeeper 的顶级安装目录。这个顶级目录似乎被 zookeeper dist 命名为 $ZOOKEEPER_PREFIX，我将其命名为 $ZOO_HOME 并将其用于 ZOO_LOG_DIR 环境变量。

在这篇文章的最后，我列出了 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。

如我所见，/home/joma/dev/programme/zk-local-ensemble/zk-server-1/bin/../conf 目录位于 CLASSPATH 上，因此 log4j.properties 文件符合条件用于通过 java 的 log4j 框架的类加载器加载资源（这是 log4j AFAIR 的实现方式）。

Answer 4

我想补充一下我是如何解决这个问题的/自定义我的环境的。

这里有两种日志机制：

• 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：
  • 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 为 zookeeper.out 和 log4j 设置路径。
• ZOO_LOG4J_PROP 设置 log4j 日志记录级别以及打开哪些日志附加程序

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

• 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 = 信息，控制台
  • 在 conf/log4j.properties 中设置为 zookeeper.root.logger

打开日志附加器 CONSOLE 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 日志最终在 zookeeper.out 中。关闭ROLLINGFILE的效果是没有创建zookeeper.log文件。

zookeeper.out 日志没有轮换。 zookeeper.log 日志设置为轮换，可以设置为过期旧日志。

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、日志级别和附加程序。

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，它就会运行：

bin/zkServer.sh start

我将其更改为指定 bin/zkServer.sh 预期的环境变量。

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

关闭日志附加器 CONSOLE 的效果是 log4j 日志现在不再以 zookeeper.out 结尾。开启ROLLINGFILE的效果是zookeeper.log文件被创建、轮换、过期。

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

这条链对我的理解做出了重大贡献： https://groups.google.com/forum/#!msg/nosql-databases/aebIvNnT0xY/doky1X9-WfwJ

Answer 5

据我所知，zkEnv.sh zookeeper/conf 文件夹已经在类路径中。有两个问题：

1. zkServer.sh 添加“-Dzookeeper.log.dir=”。到 ZK 启动命令，除非你指定 ZOO_LOG_DIR 环境变量

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

   $CLASSPATH="$ZOOCFGDIR:$CLASSPATH"

如果您的 $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，这会破坏您的类路径。 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 时会生成 -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

Answer 6

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