Grails 部署问题（WAR 和 Tomcat）答案

【问题描述】：

我正在努力在远程服务器上的 Tomcat 6 下部署 WAR。现在，如果我在本地机器上部署，一切正常。远程部署会触发一组非常不友好的异常。

我使用 HSQLDB 作为数据库。

Tomcat 作为服务运行，因此不应该有任何权限问题。我是否需要更改某些东西的权限（如果需要，因为我找不到尝试的访问权限）？我可以在 Grails 中设置一个配置选项来不记录或重定向记录吗？

【解决方案1】：

这不是关于日志记录，而是关于“prodDB.properties”。你得到一个 FileNotFoundException 因为它不能写（或可能重命名）它。运行应用程序的用户不得在其创建 HSQLDB 数据库文件的目录中具有写入权限。

默认配置使用相对路径，因此它会写入应用程序从哪里启动：

production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:hsqldb:file:prodDb;shutdown=true"
    }
}

一种解决方法是在 DataSource.groovy 中硬编码路径：

production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:hsqldb:file:/some/writeable/folder/prodDb;shutdown=true"
    }
}

更好的方法是在 Config.groovy 中启用外部配置文件：

grails.config.locations = ["classpath:${appName}-config.groovy"]

并创建 foo-config.groovy 包含

dataSource {
    url = "jdbc:hsqldb:file:/some/writeable/folder/prodDb;shutdown=true"
}

并将 foo-config.groovy 放在 Tomcat 类路径中的 $TOMCAT_HOME/lib 中（将 foo 更改为您的应用程序名称）。这样，您可以将战争部署到多个位置，并且只需覆盖配置文件，而不是在 Config.groovy 中硬编码单个值。

我在升级到 Windows 7 时突然遇到了这个问题。我一直使用快捷方式启动 Tomcat，我将“Start In”目录设置为纯“C:\”。 Windows 7 不允许非管理员用户写入此目录。我在我的用户主目录中创建了一个名为“TomcatData”的子目录，并更改了我的快捷方式以从那里启动 Tomcat。现在一切正常。
