zookeeper可视化WEB工具（zkui）搭建与配置

　　https://www.cnblogs.com/caoshousong/p/10709371.html

前提：zookeeper 可视化WEB工具zkui依赖java环境，因此需要安装jdk,同时zkui源码要Maven编译，需要安装apache-maven.

JDK下载地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Apache-maven下载地址：https://maven.apache.org/download.cgi

1.登录zkui ，选择导航“Host”　出现错误提示：KeeperErrorCode = NoNode for /appconfig/hosts  如下所示：

 

2.日志错误信息如下：

3. 

查询了该项目的Github https://github.com/DeemOpen/zkui/issues/61 并未找到解决方法；根据提示：根目录下无节点/appconfig/hosts，既然根目录下无/appconfig/hosts节点，那就手动创建；
