序：工欲善其事，必先利其器，centos7 python 有的pip都没有。。。。

yum -y install epel-release

yum -y install python-pip

pip install --upgrade pip

pip install docker-compose

在网上找了很多篇教程，看的还是半懂不懂，还是直接看视频比较快，但是视频只能帮助理解。最终还是要靠文字。

对了docker 运行容器以下形式时

docker run --name test001 -idt java:8u111-jdk

docker-compose配置需要加上tty:true

master:
  image: java:8u111-jdk
  tty: true

然后docker-compose up 才能够启动

我看的视频是B站av号：av24143098，据搬运大神说的油管地址

脚步直接复制可能无法使用，需要格式调节，我这只是记录下

视频第一部分：docker-compose.yaml

version:'3'

services: mysql-dev: image:mysql:8.0.12 enviroment: MYSQL_ROOT_PASSWORD: password MYSQL_DATABASE:blogapp ports: -"3308:3306"

docker-compose up
docker-compose ps

用客户端工具调试

视频第二部分:docker-compose.yaml

version:'3'

services: mysql-dev: image:mysql:8.0.12 enviroment: MYSQL_ROOT_PASSWORD: password MYSQL_DATABASE:blogapp ports: -"3308:3306" client: image:mysql:8.0.12 depends_on: - mysql-dev command: mysql -uroot -ppassword -hmysql-dev blogapp

说明：-hmysql-dev 和mysql-dev 一致

docker-compose run -rm client

docker-compose exec mysql-dev mysql -uroot -ppassword blogapp

第三部分：加入老的myslq:docker-compose.yaml

version:'3'

services: mysql-dev: image:mysql:8.0.12 enviroment: MYSQL_ROOT_PASSWORD: password MYSQL_DATABASE:blogapp ports: -"3308:3306"

myslq_legacty: image:mysql:5.7 enviroment: MYSQL_ROOT_PASSWORD: password MYSQL_DATABASE:legactyapp ports: -"3309:3306"

bind-address = 0.0.0.0 max_connections = 505 max_user_connections = 500

docker-compose.yaml

version:'3'

services: mysql-dev: image:mysql:8.0.12 enviroment: MYSQL_ROOT_PASSWORD: password MYSQL_DATABASE:blogapp ports: -"3308:3306" volumes: -"./my.conf:/etc/mysql/conf.d/config-file.conf"

pgdb: image:postgres enviroment: POSTGRES_USER:root POSTGRES_PASSWORD:password POSTGRES_DB:blogapp admin: image:adminer ports: - 8080:8080

#client:

image:mysql:8.0.12

depends_on:

- mysql-dev

command: mysql -uroot -ppassword -hmysql-dev blogapp

docker-compose exec pgdb pgsql  -U root -W blogapp

好了，大致是这样。对了，还有下面那个地址很重要
