使用zookeeper报错 stat is not executed because it is not in the whitelist. envi is not executed because it is not in the whitelist.

在使用四字命令或者zk ui界面查看zookeeper集群时，出现如下提示：

stat is not executed because it is not in the whitelist.
envi is not executed because it is not in the whitelist.

解决办法

# nc命令需要安装其他软件
yum install nmap-ncat
# envi命令执行报错提示：envi is not executed because it is not in the whitelist.
# 解决办法 修改启动指令 zkServer.sh ，往里面添加 ：ZOOMAIN="-Dzookeeper.4lw.commands.whitelist=* ${ZOOMAIN}"
else
    echo "JMX disabled by user request" >&2
    ZOOMAIN="org.apache.zookeeper.server.quorum.QuorumPeerMain" # 注意找到这个信息
fi
# 如果不想添加在这里，注意位置和赋值的顺序
ZOOMAIN="-Dzookeeper.4lw.commands.whitelist=* ${ZOOMAIN}"
然后重启zookeeper
