一.下载docker-compose

https://download.csdn.net/download/cyw8998/89093489   2.172

https://download.csdn.net/download/cyw8998/89122396   2.5

拷贝到/usr/local/bin中，并赋权限chmod +x /usr/local/bin/docker-compose

二.安装docker traefik:v2.4

docker pull traefik:v2.4

或者直接下载镜像

三.docker-conpose.yml配置

#abc#
version : '3.7'

1.运行命令

docker-compose  up -d  traefik

docker-compose  up -d  db1

docker-compose  up -d  db2

注意pxc8需要集群需要证书验证

生成证书命令见另一篇文章
