当我这样做的时候

bin/zkCli.sh -server 127.0.0.1:2183

服务器正在启动吗？可能未给出：

server.1=localhost:2878:3878
server.2=localhost:2879:3879
server.3=localhost:2880:3880

如果您在同一台主机上运行所有三台服务器，则它们需要各自具有不同的配置-尤其是datadir位置必须不同，并且您需要确保每个datadir都具有对应于服务器行的myid文件（即配置中的server.#）

通常，当您想要在分布式模式下运行时，需要有单独的主机。在这种情况下，为什么不在独立（默认）模式下运行

我建议您先阅读《管理指南》中的更多内容：

我遇到了同样的问题，即从客户端代码直接连接到mapr m3

问题是客户端试图连接到本地主机上的M3 zookeeper

我的M3集群上的

/opt/mapr/conf/mapr clusters.conf

指向本地主机。。。我把它改为M3机器的ip地址，客户端的连接正常

/opt/mapr/conf/cldb.conf

添加ip地址以代替本地主机

然后重新启动zookeeper，确保所有必需的服务都在运行

sudo /usr/lib/zookeeper/bin/zkServer.sh stop
sudo /usr/lib/zookeeper/bin/zkServer.sh start

步骤1：检查hbase主机是否正在运行

sudo /etc/init.d/hbase-master status

sudo /etc/init.d/hbase-regionserver status

sudo /etc/init.d/zookeeper-server status

如果没有，则启动它

sudo/etc/init.d/hbase-master start

步骤2：检查hbase regionserver是否正在运行

sudo /etc/init.d/hbase-master status

sudo /etc/init.d/hbase-regionserver status

sudo /etc/init.d/zookeeper-server status
如果没有，则启动它
sudo/etc/init.d/hbase-regionserver start
步骤3：检查zookeeper服务器是否正在运行

sudo /etc/init.d/hbase-master status

sudo /etc/init.d/hbase-regionserver status

sudo /etc/init.d/zookeeper-server status
如果没有，则启动它
sudo/etc/init.d/zookeeper-server start

或只需连续运行这3个命令。

sudo /etc/init.d/hbase-master restart sudo /etc/init.d/hbase-regionserver restart sudo /etc/init.d/zookeeper-server restart
之后别忘了检查状态

sudo /etc/init.d/hbase-master status sudo /etc/init.d/hbase-regionserver status sudo /etc/init.d/zookeeper-server status
您可能会发现zookeeper仍然没有运行：然后你可以运行动物园管理员

sudo /usr/lib/zookeeper/bin/zkServer.sh stop sudo /usr/lib/zookeeper/bin/zkServer.sh start
然后再次检查状态并确保其正在运行

sudo /etc/init.d/zookeeper-server status

这应该可以工作。
如何检查服务器是否启动？问题是我没有在数据目录中创建myid文件，也没有启动Zooketter服务器
