我正在使用以下配置以持久模式启动 ignite db -

<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">
    <!--
        Alter configuration below as needed.
    -->
    <bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
     <!-- Enabling Apache Ignite Persistent Store. -->
        <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>
            </bean>
        </property>
    </bean>
</beans>

此配置在config/default-config.xml文件中

之后我开始使用 sqlline 控制台 -

sqlline.sh --color=true --verbose=true -u jdbc:ignite:thin://127.0.0.1/

在控制台中，当我执行任何 DDL 查询时，它会给出以下错误 -

java.sql.SQLException: Can not perform the operation because the cluster is inactive. Note, that the cluster is considered inactive by default if Ignite Persistent Store is used to let all the nodes join the cluster. To activate the cluster call Ignite.active(true).

    at sqlline.SqlLine.start(SqlLine.java:373)
    at sqlline.SqlLine.main(SqlLine.java:265)

我应该如何激活集群？我在哪里调用 Ignite.active(true)？

注意：我在 ubuntu 18.0.4 中使用 Gridgrain ignite 社区版 8.7.5 版

最简单的方法是使用control.sh脚本，您可以在 bin 目录中找到该脚本：

control.sh --activate

其他方式已记录在案。
