docker部署mysql
1：安装docker
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun2：查看docker版本
docker -v
Docker version 24.0.7, build afdd53b3：配置docker镜像加速器
vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://yxzrazem.mirror.aliyuncs.com"]
}4：拉取mysql 5.7镜像
docker pull mysql:5.75：创建并运行mysql容器
docker run -d -p 3306:3306 --privileged=true -v /opt/mysql/log:/var/log/mysql -v /opt/mysql/data:/var/lib/mysql -v /opt/mysql/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=oracle --name mysql mysql:5.7
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b0a4886c04b8 mysql:5.7 "docker-entrypoint.s…" 7 seconds ago Up 6 seconds 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp mysql6：新建my.cnf
cd /opt/mysql/conf
vi my.cnf
[client]
default_character_set=utf8
[mysqld]
collation_server = utf8_general_ci
character_set_server = utf87：重新启动mysql容器实例
docker restart b0a4886c04b8
docker exec -it b0a4886c04b8 /bin/bash
8：连进mysql容器，并建库建表
