Grails WAR 部署问题

Question

大家好，我在设置 Grails 应用程序时遇到了一些问题。从netbeans运行应用程序没有问题（在windows 7 64位上）也使用apache2和tomcat 7在同一台计算机上部署war文件工作正常。在尝试在 Plesk 中部署都失败后，tomcat 根本无法启动。所以我尝试在我自己的 linux 环境中设置它（ubuntu 10 使用 apache2 和 tomcat6） 这里服务器工作正常，除了 war 文件不会运行并且我在 catalina.out 中得到一个很好的异常：

java.io.FileNotFoundException: stacktrace.log (Permission denied)
at java.io.FileOutputStream.openAppend(Native Method)

随后是堆栈跟踪和另一个错误：

 INFO: Deploying web application archive SuurdGasControl.war
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: stacktrace.log (Permission denied)

任何关于如何解决这个问题的帮助都会很棒！

Answer 1

Grails 尝试写入文件 stacktrace.log，它位于您启动 tomcat 的目录中。 “权限被拒绝”错误可能意味着 tomcat 缺乏对该文件夹的写访问权限。也许你是从一个 tomcat 进程无权访问的文件夹启动 tomcat 的？尝试从例如启动tomcat它的日志目录（运行../bin/startup.sh）并查看是否有效。

编辑：以上是错误 #2。基本原因看起来是使用数据源初始化 spring bean 的问题。用户 'grails'@'localhost' 在 localhost 无权访问您的 MySQL 数据库

Answer 2

问题似乎是使用启动tomcat没有创建stacktrace.log文件的权限。 stacktrace.log 文件的位置和/或存在可以在 Config.groovy 中控制。

请参阅“完整堆栈跟踪”部分中的 official documentation。

Answer 3

您必须更改部署 root.war 的文件夹的权限。

这似乎相关： http://www.grails.org/Deployment/#Tomcat

“请注意，在默认设置下，Grails 将尝试将某些文件写入 tomcat 目录，通常是 stacktrace.log 和 h2 数据库。您的 Tomcat 目录可能安装有 root 的所有者/组，而 Tomcat 服务器以用户 tomcat6 运行。这将导致您的应用程序无法启动并出现写权限错误。要么更改 Grails 生产设置，以便将这些文件写入其他位置具有正确权限的目录，要么更改 Tomcat 目录的所有者（对于 Unix：/ var/lib/tomcat6) 到 tomcat6（或您使用 TOMCAT6_USER 设置设置的任何 tomcat 用户）。"

适合我的配置如下：

log4j 配置

log4j = {

appenders {
    environments {
        development {
            console name: 'stdout', layout: pattern(conversionPattern: '%-5p %d{HH:mm:ss,SSS} %c{2} %m%n')
        }

        production {
            appender new org.apache.log4j.DailyRollingFileAppender(
                    name: 'file',
                    datePattern: "'.'yyyy-MM-dd",
                    file: System.properties['catalina.base'] + "/logs/mylog-web.log",
                    layout: pattern(conversionPattern: '%d [%t] %-5p %c{2} %x - %m%n')
            )
            rollingFile name: "stacktrace", maxFileSize: 1024 * 10,
                    file: System.properties['catalina.base'] + "/logs/mylog-web-stacktrace.log"
        }
    }
}

error 'org.codehaus.groovy.grails.web.servlet', // controllers
        'org.codehaus.groovy.grails.web.pages', // GSP
        'org.codehaus.groovy.grails.web.sitemesh', // layouts

        'net.sf.ehcache.hibernate'

environments {
    development {
        debug 'mydomain.blabla'
        error stdout: "StackTrace"
        //log4j.debug 'org.hibernate.type'
        //log4j.debug 'org.hibernate.SQL'
    }
    production {
        root {
            warn 'file'
        }
    }
}

}

基本上，您必须将堆栈跟踪日志设置为您拥有写入权限的文件夹日志
