相关版本说明

JDK：JDK (1.8）
DolphinScheduler ：3.1.9
数据库：MySQL (8+)，驱动：MySQL JDBC Driver 8.0.16
注册中心：ZooKeeper (3.8.4)

问题一：dolphinscheduler2.0.9对应zk版本使用3.4.6即可，但是dolphinscheduler3.1.9需要使用3.8.4版本（官方没有说明版本要求），这个时候部署3.8.4版本会出现这个错误：

2025-01-10 11:23:11,250 [myid:] - ERROR [main:o.a.z.s.ZooKeeperServerMain@86] - Unable to start AdminServer, exiting abnormally

解决：配置zoo.cfg文件admin.serverPort=8089

问题二：执行部署语句出现NoClassDefFoundError

11:29:21.120 [main] DEBUG org.apache.zookeeper.ZooKeeperMain - Processing deleteall
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/DefaultParserat org.apache.zookeeper.cli.DeleteAllCommand.parse(DeleteAllCommand.java:52)at org.apache.zookeeper.ZooKeeperMain.processZKCmd(ZooKeeperMain.java:438)at org.apache.zookeeper.ZooKeeperMain.processCmd(ZooKeeperMain.java:367)at org.apache.zookeeper.ZooKeeperMain.run(ZooKeeperMain.java:350)at org.apache.zookeeper.ZooKeeperMain.main(ZooKeeperMain.java:293)

原因：commons-cli-1.2.jar版本过低
解决：使用commons-cli-1.4.jar解决，替换安装目录下commons-cli-1.2.jar版本

/dolphinschedul/api-server/libs/commons-cli-1.4.jar
/dolphinschedul/master-server/libs/commons-cli-1.4.jar
dolphinschedul/worker-server/libs/commons-cli-1.4.jar

问题三：部署的时候使用dolphinscheduler用户部署，但对应安装包目录没有权限

解决：chown -R dolphinscheduler.dolphinscheduler /home/apache-dolphinscheduler-3.1.9-bin/
