上传geoserver的war包到tomcat的webappsmu目录。然后启动tomcat.war包回自动解压
访问ip:8080/geoserver
默认的账号密码为 admin geoserver
各节点都需要完成上述操作
将geoserver-2.18-SNAPSHOT-activeMQ-broker-plugin.zip解压
将其中的war包上传到主节点的tomcat(其他tomcat也行)中
启动tomcat后自动解压，将/usr/local/tomcat/apache-tomcat-9.0.37/webapps/activemqBroker-2.18-SNAPSHOT/WEB-INF/classes目录下的 standalone-broker.properties和applicationContext.xml删除
重启tomcat
以上操作在一个tomcat中完成即可
解压jms的zip包
将解压后的所有.jar包复制到tomcat中webapps/geoserver/WEB-INF/lib目录下
重启tomcat,等待geoserver启动成功
在/usr/local/tomcat/apache-tomcat-9.0.37/webapps/geoserver/data目录下生成cluster目录
其中包含以两个文件cluster.properties、embedded-broker.properties
如果需要修改geoserver的默认数据文件，需要修改以下文件
修改tomcat启动文件，指定数据文件位置
找到以下代码：
JAVA_OPTS=“$JAVA_OPTS $JSSE_OPTS"
修改为：
JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -DCLUSTER_CONFIG_DIR=/data1/geoserver/data/cluster/clusterConfig3"
各节点目录名称可不相同
重启tomcat 生成数据存储目录
每个节点都完成以上操作
在/data1/geoserver/data/cluster/clusterConfig3（此目录为上面脚本中指定的目录）目录下新建broker.xml文件内容如下(三个节点均要新建，内容相同)
vim broker.xml
复制下面内容到文件中，无须修改

集群中只有一个节点是主节点，在这个节点新增数据，别的节点会根据activeMQ进行同步
修改各节点以下文件（文件路径为geoserver 数据目录下cluster目录中）
修改cluster.properties配置文件 只改brokerURL，其他参数默认

toggleSlave=true
connection=enabled
topicName=VirtualTopic.geoserver
brokerURL=tcp\://192.168.144.17\:61616 #AMQ地址 此文件各节点配置相同

修改embedded-broker.properties 修改下面行
重新启动各节点tomcat
访问geoserver 登录后可以看到cluster信息
