解决Zookeeper报错:conf is not executed because it is not in the whitelist的解决办法

1.echo wchp | nc localhost 2181 ,通过路径列出服务器 watch 的详细信息，且它会输出一个与 session 相关的路径。但是出现下面的错误。

[root@xg61 conf]# echo wchp | nc localhost 2181
wchp is not executed because it is not in the whitelist.

2.cd /usr/local/zookeeper/conf下，用vim打开zoo.cfg，在最后添加:

4lw.commands.whitelist=*

3.重启Zookeeper的服务器和客户端。

./zkServer.sh restart
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

服务器重启成功，接着开启客户端。

[root@xg61 bin]# ./zkCli.sh
