一开始怀疑是zoo.cfg损坏,但查看后发现文件没有明显异常。将/opt/zookeeper-3.4.13/data/version-2目录改名为version-2.bak后重启zookeeper正常(但client连接报错 zxid 0x02 our last zxid is 0x0 client must try another server,因为前面的操作导致zk这边的事务id被重置了),说明可能是data下有文件损坏。

进一步查看version-2.bak下的文件,发现有一个0字节的log文件:

file

删除此文件并将version-2.bak改回原来的名字version-2,重启zookeeper成功,并且client连接正常。
