2、启动失败 1、启动失败JAVA_HOME is not set and java could not be found in PATH 已安装 JAVA 配置了JAVA_HOME,还是报错解决方法：参考： blogs /OnlyDreams/p/16694263.html替换启动命令为 ./zkServer.sh start或bash zkServer.sh start

2、启动失败 ClassNotFoundException: org.apache.zookeeper.server.quorum.QuorumPeerMain [root@xxx] zkServer.sh start-foreground ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Error: Could not find or load main class org.apache.zookeeper.server.quorum.QuorumPeerMain Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.server.quorum.QuorumPeerMain

3、启动失败，端口8080被占用 Caused by: java.io.IOException: Failed to bind to /0.0.0.0:8080

解决方法：

参考： blog.csdn.net/lihaitao910215/article/details/105176064修改配置，在zoo.cfg中添加了一行配置：admin.serverPort=8001

---

4、启动失败，端口2181被占用 java.net.BindException: Address already in use

查看端口占用：lsof -i:2181发现没有端口占用

修改配置：修改conf/zoo.cfg中的clientPort=2181 为clientPort=21810

3 启动成功 服务端启动成功：bash zkServer.sh status start查看服务端状态:bash zkServer.sh status停止服务端：bash zkServer.sh stop启动客户端:bash zkCli.sh
