修改原集群的/opt/apache-zookeeper-3.6.3-bin-bcm/conf/zoo.cfg中的集群配置信息。

       
            server.80=ceph1:2889:3889;2182
server.90=ceph2:2889:3889;2182
server.100=ceph3:2889:3889;2182
server.4=ceph4:2889:3889;2182
server.5=ceph5:2889:3889;2182

按leader节点最后重启，其余节点按myid从小到大的顺序重启原则，重启各节点的zkserver。

ceph1（follower）：

       
            /opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh restart

ceph2（follower）：

       
            /opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh restart

ceph3（leader）：

       
            /opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh restart

每个节点分别执行/opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh status 确认原集群状态

       
            [root@ceph3 bin]# /opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh status
