Исключение прерывистой трубы с MySql в приложении Grails

Я развернул приложение Grails 2.2.1 на удаленном сервере. Через несколько часов, когда я получаю доступ к домашней странице приложения, я вижу следующее исключение:

Error 500: Internal Server Error

Я попытался решить проблему, как видно из другого вопроса в SO, но это не работает для меня.

Вот что я сделал внутри файла конфигурации:

dataSource {
        dbCreate = "update"
        url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8"
        username = "root"
        password = "root"
        //run the evictor every 30 minutes and evict any connections older than 30 minutes.
        minEvictableIdleTimeMillis=1800000
        timeBetweenEvictionRunsMillis=1800000
        numTestsPerEvictionRun=3
        //test the connection while its idle, before borrow and return it
        testOnBorrow=true
        testWhileIdle=true
        testOnReturn=true
        validationQuery="SELECT 1"
    }

Обратите внимание, что если я обновляю страницу, все работает правильно. Кто-нибудь знает что-то, чтобы решить эту проблему?

РЕДАКТИРОВАТЬ 1:

Я отредактировал файл my.cnf в папке /etc, добавив следующее:

wait_timeout = 28800
interactive_timeout = 28800

но ничего не меняется

ИЗМЕНИТЬ 2:

Это фактический источник данных, который я использую. Сломанная труба все еще появляется

   dbCreate = "update"
   url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"

Ответ 1

Поэтому я считаю, что в блоке свойств должно быть все, кроме dbCreate, url, username и password:

dataSource {
    dbCreate = "update"
    url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"
    username = "root"
    password = "root"
    properties {
        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;StatementCache(max=200)"
        defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
    }
}

Ответ 2

Хотя это должно быть странно, но если приложение Grails и сервер MySQL находятся на одной машине, используйте localhost или 127.0.0. вместо реального IP-адреса xxx.xxx.xxx.xxx

dataSource {
   dbCreate = "update"
   url = "jdbc:mysql://localhost:3306/docgem_test_db?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"
   // Your other properties
}

Ответ 3

Пожалуйста, попробуйте ниже, не добавляя driverClassName и dialect, и я также добавил pooled, если вам понадобится

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
    dbCreate = "update"
    url = "jdbc:mysql://urlofapp/myappname? useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"
    username = "root"
    password = "root"
    properties {
        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;StatementCache(max=200)"
       defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
}

}

Ответ 4

Похоже на то, что MySQL отключает подключение к вам. Вероятно, вы не можете это сделать.

Можно ли закрыть соединение, если на нем нет трафика, а затем снова открыть его, когда он понадобится снова?
