Question

我想在ignite中启用持久性，以便在ignite docker容器重新启动或替换为新版本时不会丢失缓存数据。

我正在使用ignite 2.6.0。这是配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans.xsd">
   <bean id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
      <property name="dataStorageConfiguration">
         <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
            <property name="defaultDataRegionConfiguration">
               <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                  <property name="persistenceEnabled" value="true" />
               </bean>
            </property>           
            <property name="storagePath" value="/opt/ignite/apache-ignite-fabric/data/persistence" />           
            <property name="walPath" value="/opt/ignite/apache-ignite-fabric/data/wal" />
            <property name="walArchivePath" value="/opt/ignite/apache-ignite-fabric/data/wal/archive" />
         </bean>
      </property>          
      <property name="discoverySpi">
         <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
            <property name="ipFinder">            
               <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
                  <property name="addresses">
                     <list>
                        <value>127.0.0.1:47500..47502</value>
                     </list>
                  </property>
               </bean>
            </property>
         </bean>
      </property>
   </bean>
</beans>

我运行以下命令来部署可点燃docker容器

sudo docker run -d -e "CONFIG_URI=" -e "OPTION_LIBS=ignite-core,ignite-spring,ignite-indexing,ignite-rest-http" -v /var/ignitedata:/opt/ignite/apache-ignite-fabric/data -p 9005:8080 --name=apacheignite apacheignite/ignite:2.6.0

我没有将任何值传递给CONFIG_URI是因为我替换了Docker容器中的default-config.xml文件。

我使用ignite rest api创建了一个新缓存

http://localhost:9005/ignite?cmd=getorcreate&cacheName=myCache

将示例值添加到缓存

http://localhost:9005/ignite?cmd=put&key=10&val=2018-01-01&cacheName=myCache&keyType=int&valueType=date

我可以检索缓存值

http://172.30.5.28:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date

现在，如果我重新启动docker容器并尝试获取值，它不会返回值

http://localhost:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date

有人见过这个问题吗？

谢谢，拉胡尔

Answer 1

启动集群后是否激活了集群？使用持久性时，您需要告诉Ignite它期望看到多少个节点（称为“基准”）。

您可以通过运行control.sh脚本来做到这一点：

./control.sh --activate

Answer 2

您必须确保Docker容器仍然挂载了相同的存储，还必须在配置中将consistentId设置为相同的值。

如果执行此操作，则所有节点加入后，群集将自动激活。您只需要手动激活一次即可。

感谢Andrei Aleksandrov为我指出正确的方向。我添加了工作目录路径，这有助于解决问题。发布更新的default-config.xml

重新启动Docker容器时，点燃的缓存数据会丢失
