Kubernetes Skywalking 【单Zookeeper + Dubbo Provider + Dubbo Consumer】
一、安装JDK11（8也行）
[root@xianchaonode1 sbin]# java -version
openjdk version "11.0.18" 2023-01-17 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.18.0.10-1.el7_9) (build 11.0.18+10-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.18.0.10-1.el7_9) (build 11.0.18+10-LTS, mixed mode, sharing)二、下载Zookeeper 并且安装:192.168.40.181
下载地址：https://dlcdn.apache.org/zookeeper/zookeeper-3.6.4/apache-zookeeper-3.6.4-bin.tar.gz
apache-zookeeper-3.6.3-bin.tar.gz
tar zxvf apache-zookeeper-3.6.3-bin.tar.gz
mkdir -p /data/zookeeper

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
