zookeeper启动报 Unexpected exception, exiting abnormally 错误-CFANZ编程社区

当我们在集群里启动zookeeper的时候,通过jps查看没有发现zookeeper进程

zookeeper启动报 Unexpected exception, exiting abnormally 错误_zookeeper

通过查看zookeeper日志

zookeeper启动报 Unexpected exception, exiting abnormally 错误_zookeeper_02

其实是因为2181端口被占用的原因！！！

通过命令sudo netstat -nltp | grep 2181查看是那个进程占用了2181端口，然后把相应的进程kill掉

zookeeper启动报 Unexpected exception, exiting abnormally 错误_zookeeper_03

再次启动zookeeper

zookeeper启动报 Unexpected exception, exiting abnormally 错误_zookeeper_04

zookeeper启动报 Unexpected exception, exiting abnormally 错误_zookeeper_05

完成！！！
