解決Zookeeper報錯:conf is not executed because it is not in the whitelist的解決辦法

1.echo wchp | nc localhost 2181 ,通過路徑列出服務器 watch 的詳細信息，且它會輸出一個與 session 相關的路徑。但是出現下面的錯誤。

[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打開zoo.cfg，在最后添加:

4lw.commands.whitelist=*

3.重啟Zookeeper的服務器和客戶端。

./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

服務器重啟成功，接着開啟客戶端。

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