zookeeper-错误排查-java.net.NoRouteToHostException: 没有到主机的路由 (Host unreachable)

1.执行中出现错误

bin/zkServer.sh start

JMX enabled by default Using config: /opt/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg Starting zookeeper ... /opt/zookeeper/zookeeper-3.4.5/bin/zkServer.sh: 第 103 行:[: /tmp/zookeeper: 期待二元表达式 STARTED

原因是配置文件中zoo.cfg 有个多余的参数dataDir

2.使用bin/zkServer.sh status

出现错误的话

我的建议是查询zk日志，基本上一眼就可以发现问题

日志为zookeeper.out

zoo.cfg中可以通过dataLogDir来配置zookeeper的事务日志的输出目录。
