# 新节点加入集群

以ceph4，ceph5作为新节点为例，加入新集群。

1. 参考安装ZooKeeper安装zookeeper软件包。
2. 配置新节点的myid，ceph4 myid（4），ceph5 myid（5）
  ceph4：

  1 2 mkdir /opt/apache-zookeeper-3.6.3-bin-bcm/zkData echo 4 > /opt/apache-zookeeper-3.6.3-bin-bcm/zkData/myid

  ceph5：

  1 2 mkdir /opt/apache-zookeeper-3.6.3-bin-bcm/zkData echo 5 > /opt/apache-zookeeper-3.6.3-bin-bcm/zkData/myid

3. 配置新节点的配置文件/opt/apache-zookeeper-3.6.3-bin-bcm/conf/zoo.cfg

4. 启动新节点zookeeper服务
  1 /opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkServer.sh start

5. 查询新节点的zookeeper服务状态
