tomcat - Grails 应用程序无法在 Tomcat7 中启动 - 无法从日志中获取任何有用的信息？

Question

我将 grails 2 应用程序部署到 tomcat7 中，但它就是无法启动。我尝试了很多方法来从 catalina.out 或我的应用程序日志中获取任何信息，但我得到的只是

Jul 30, 2012 5:47:40 PM org.apache.catalina.core.StandardEngine startInternal
INFO: Starting Servlet Engine: Apache Tomcat/7.0.28

Jul 30, 2012 5:47:49 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 8372 ms

我已经将 logging.properties 放入/var/lib/tomcat/webapps/myApp/WEB-INF/classes 中包含

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

但这也没有给我任何更多信息。

此外，我将 grails 应用程序的日志级别更改为调试，但也没有出现错误。目前我不知道如何从 tomcat 或应用程序中获取任何有用的信息，帮助我找到错误:(

干杯，

更新:

对于我尝试运行的环境，我的 Config.groovy 看起来像这样:

staging {
    def logDirectory = "/var/log/myApp"

    log4j = {
        appenders {
            rollingFile name: 'stacktrace', file: "${logDirectory}/stacktrace.log".toString(), maxFileSize: '10MB'
            rollingFile name: 'myLog', file: "${logDirectory}/myApp_debug.log".toString(), maxFileSize: '10MB'
        }

        root {
            // change the root logger to myLog file
            debug 'myLog'
        }

        debug  'grails.app'
        debug  'org.codehaus.groovy.grails.commons' // Core artifact information such as class loading etc.
        debug  'org.codehaus.groovy.grails.web' //Grails web request processing
        debug  'org.codehaus.groovy.grails.web.mapping' // URL mapping debugging
        debug  'org.codehaus.groovy.grails.plugins' //  Log plugin activity
        warn  'grails.spring' // See what Spring beans Grails and plugins are defining
        debug  'org.springframework' // See what Spring is doing
        debug  'org.hibernate' // See what Hibernate is doing
        debug  'org.codehaus.groovy.grails.web.servlet'  //  controllers
        debug  'org.codehaus.groovy.grails.web.pages' //  GSP
        info  'org.apache.catalina' // tomcat

        // set level for my messages; this uses the root logger (and thus the tomcatLog file)
        debug 'myApp_debug.log'
    }

    grails.serverURL = "someUrl"
}

查看所有日志文件 - catalina.out 中很少有真正的问题。 logs/localhost.2012-07-30.log 和 stacktrace.log 是您最好的选择。
