centos7环境用docker-compose部署mysql5.7集群，redis7.2.4，springboot项目

文件目录结构

关于每个配置项及docker-compose的安装，大家可以自己查

编排

命令行

docker-compose up -d

结果

此时mysql仍未集群，需要进入miouo-mysql5.7-master,miouo-mysql5.7-slave-1,miouo-mysql5.7-slave-2中进行联通

miouo-mysql5.7-master --- 连接主节点创建复制账号

miouo-mysql5.7-slave-1 --- 连接从节点重置主

miouo-mysql5.7-slave-2 --- 连接从节点重置主

集群结果

项目测试
