zookeeper：Error contacting service. It is probably not running. and Unable to read additional data from server sessionid 0x0, likely server has closed socket, closing socket connection and attempting reconnect
在配置Zookeeper的时候遇到的错误如题所示，具体如下：
|
1 2 3 4 5 6 7 8 9 10 |
[root@redis1 conf]# zkServer.sh start ZooKeeper JMX enabled by default Using config: /software/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg Starting zookeeper ... STARTED [root@redis1 conf]# [root@redis1 conf]# zkServer.sh status ZooKeeper JMX enabled by default Using config: /software/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg Error contacting service. It is probably not running. [root@redis1 conf]# |
这种情况下你去访问服务器，其实是有问题的：
