Question

我想在嵌入式H2数据库，Tomcat和Gradle的Linux服务器上运行Grails应用程序。规格低于

Grails 2.4.4
Groovy 2.3.7
Gradle 2.2.1
Tomcat 7.0.59
Linux CentOS 6

BuildConfig.groovy如下所示

dependencies {
    test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"
}
plugins {
    build ":tomcat:7.0.55"
    compile ":scaffolding:2.1.2"
    compile ':cache:1.1.8'
    compile ":asset-pipeline:1.9.9"
    runtime ":hibernate4:4.3.6.1"
    runtime ":database-migration:1.4.0"
    runtime ":jquery:1.11.1"
}

Detasourece.groovy位于

之下

dataSource {
    pooled = true
    jmxExport = true
    driverClassName = "org.h2.Driver"
    username = "sa"
    password = ""
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
//    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
    singleSession = true // configure OSIV singleSession mode
    flush.mode = 'manual' // OSIV session flush mode outside of transactional context
}

// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
            properties {
               // See http://grails.org/doc/latest/guide/conf.html#dataSource for documentation
               jmxEnabled = true
               initialSize = 5
               maxActive = 50
               minIdle = 5
               maxIdle = 25
               maxWait = 10000
               maxAge = 10 * 60000
               timeBetweenEvictionRunsMillis = 5000
               minEvictableIdleTimeMillis = 60000
               validationQuery = "SELECT 1"
               validationQueryTimeout = 3
               validationInterval = 15000
               testOnBorrow = true
               testWhileIdle = true
               testOnReturn = false
               jdbcInterceptors = "ConnectionState"
               defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
                }
        }
    }
}

使用此配置，我制作了一个war文件。

grails prod war

然后，我在Linux服务器上部署了Grails应用程序。 Tomcat跑得很好。我可以访问http://myserver:8080。之后，我访问了http://myserver:8080/application/。结果，它返回了http代码。

HTTP Status 404

我检查了/etc/local/tomcat/log/stacktrace.log

Answer 1

看起来是权限问题，它正在尝试在根目录中创建文件。

尝试将prod env中的数据源URL更改为

 url = jdbc:h2:~/db/test;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"

Answer 2

我过去常常使用它的另一种方法 - 如果你不需要将数据库保留在磁盘上 - 就是将生产数据库放入这样的内存：

url = jdbc:h2:mem:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"

这不取决于服务器上的任何磁盘权限（例如，您甚至没有帐户的生产环境，因此“〜/”不是有效目录。）

无法在Linux服务器上运行Grails应用程序 - Tomcat和H2数据库
