【问题描述】

通过管理台体验长安链无法访问localhost,报错cm_mgmt_server_1 | panic: dial tcp 172.20.0.2:3306: connect: connection refused

【系统信息】

• chainmaker-go version * : [v2.3.0]
• **OS & version * :centOS7.6
• **docker镜像 version:20.10.7

一、软硬件环境 4核8G 硬盘:100G 操作系统 centos7.6 4vCPU 8GiB

二、操作步骤 1、按照文档《通过管理台体验长安链》 https://docs.chainmaker.org.cn/v2.3.0_alpha/html/quickstart/%E9%80%9A%E8%BF%87%E7%AE%A1%E7%90%86%E5%8F%B0%E4%BD%93%E9%AA%8C%E9%93%BE.html

部署docker管理平台并部署4个docker链节点,docker版本为20.10.7或以上 docker-compose 版本为1.29.2或以上
