2. 修改tocat端口解决8080端口占用
3. 解决zookeeper maven冲突

    安装版本号

• 启动: sh bin/zkServer.sh start
• 查看服务状态: sh bin/zkServer.sh status
• 停止: sh bin/zkServer.sh stop
• 重启: sh bin/zkServer.sh restart
• get /services/application/2bf4ff71-16ad-4965-b7ba-1e095c29dd7f

sudo find / -name tomcat
找到tomcat/conf/server.xml 修改端口号

• 状态
  systemctl status firewalld
• 开启
  systemctl start firewalld
• 停止
  pkill -f firewall //杀死进程
  systemctl stop firewalld
• 开机启动
  systemctl enable firewalld
• 禁用开机启动
  systemctl disable firewalld
