如何清除JBoss中的server.log?

JBoss 正在运行时,如何清除JBoss 的server.log 文件?当我尝试这样做时,

echo 1 > server.log

我收到错误消息,表明另一个程序(JBoss)正在使用该文件。是否可以使用命令行工具(windowslinux(我有 CygWin))或我可以自己编写的应用程序清除该文件?

PS 我不需要该文件有 0kb,但我希望它小于 100MB

How do I clear JBoss' server.log file when JBoss is running? When I try to do

echo 1 > server.log

I get error msg that the file is being used by another program (JBoss). Is it possible to use a command-line tool (windows or linux(I do have CygWin)) or an application that I can write myself to clear that file?

P.S. I don't need that file to have 0kb, but I want it to have less than 100MB.

默认情况下,JBoss 保持文件锁定,因为它正在向其中写入日志消息。只要 JBoss 正在运行,它就会被锁定,除了停止 JBoss 本身之外,我不知道还有其他方法可以释放它。

为了控制其大小,您可以修改日志配置,默认情况下位于 /conf˛jboss-log4j.xml 中。您可以指定日志文件的最大大小,并定义达到该大小时要执行的操作:滚动到新文件、截断现有文件并重新开始写入等。

一个基本示例(未经测试,因此不保证它能正常工作):

    <appender name="ROLL" class="org.apache.log4j.rolling.RollingFileAppender">
            ...
            <param name="maxFileSize" value="100MB" />
            ...
    </appender>

此外,使用 maxBackupIndex 参数,您可以定义备份文件的数量(默认为 1)。

By default JBoss keeps the file locked, since it is writing log messages into it. It is locked as long as JBoss is running and I don't know of other way to release it than stopping JBoss itself.

To keep its size under control, you can modify your log configuration, which is by default in <server>/conf˛jboss-log4j.xml. You can specify the maximum size of a log file, and define what to do when that size is reached: roll over to a new file, truncate the existing one and start writing over it again, etc.

A basic example (not tested, so no guarantee that it works straight as it is):

    <appender name="ROLL" class="org.apache.log4j.rolling.RollingFileAppender">
            ...
            <param name="maxFileSize" value="100MB" />
            ...
    </appender>

Moreover, with the maxBackupIndex parameter you may define the number of backup files (default is 1).

只要日志记录进程正在运行,JBoss 就会锁定该文件。

如果启用了 JMX 控制台,您可以停止日志记录、删除/修改日志,然后再次启动日志记录服务。

url 应如下所示(对于 log4j):

http://jboss.example.com:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.system%3Atype%3DLog4jService%2Cservice%3DLogging

我测试过这与 JBoss 5 一起使用。

该解决方案也应该是可编写脚本的。

关于您的日志文件大小问题:您应该使用配置方法而不是手动编辑日志文件。

JBoss locks the file as long as the logging process is running.

If you enabled the JMX console you can stop the logging, delete / modify the log, and start the logging service again.

The url should look something like this (for log4j):

http://jboss.example.com:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.system%3Atype%3DLog4jService%2Cservice%3DLogging

I tested this with JBoss 5.

This solution should be scriptable as well.

Regarding your log file size problem: You should use a configuration approach instead of editing the log file manually.

要清除 JBoss 中的日志,您可以按照以下步骤操作:

  1. 停止 JBoss 服务器:在清除日志之前,最好停止 JBoss 服务器,以防止在清除日志时出现任何潜在问题。
  2. 导航到日志目录:找到 JBoss/WildFly 存储日志文件的目录。该目录通常在 JBoss/WildFly 安装目录中命名为standalone/log 或domain/servers/server-name/log。
  3. 清除日志文件
  4. 启动JBoss 服务器:清除日志后,您可以再次启动JBoss 服务器。

To clear logs in JBoss, you can follow these steps:

  1. Stop the JBoss Server: Before you clear the logs, it's a good practice to stop the JBoss server to prevent any potential issues while the logs are being cleared.
  2. Navigate to the Log Directory: Locate the directory where JBoss/WildFly stores its log files. This directory is typically named standalone/log or domain/servers/server-name/log within your JBoss/WildFly installation directory.
  3. Clear the log file
  4. Start the JBoss Server: After you've cleared the logs, you can start the JBoss server again.
