sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose


chmod +x /usr/local/bin/docker-compose


 ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

docker-compose version

容器创建

创建网络
设置固定ip

docker network create --subnet=172.19.0.0/18 mynetwork

docker-compose安装 mysql

遇到的问题
changing ownership of '/var/lib/mysql/': Permission denied
设置 privileged: true 属性

privileged: true  容器设置root属性
command: --lower_case_table_names=1   忽略大小写

 networks:
      default:
        ipv4_address: 172.19.0.2  绑定ip
