第一步：首先安装docker 和docker-compose
这里使用快速安装脚本进行安装
curl -sSL https://get.daocloud.io/docker | sh第二步：新建/data/mysql目录 data文件是我以后存放所有安装的容器地址
新建一个docker-compose.yml文件夹
version: '3'services: mysql: image: mysql:5.7 restart: always container_name: mysql environment: MYSQL_ROOT_PASSWORD: chen command: --default-authentication-plugin=mysql_native_password --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci --explicit_defaults_for_timestamp=true --lower_case_table_names=1 --max_allowed_packet=128M; ports: - 3306:3306 volumes: - /data/mysql:/var/lib/mysql - /etc/localtime:/etc/localtime:ro~ 默认数据库是账号是root
密码自己修改 MYSQL_ROOT_PASSWORD
进入到docker compose文件的目录下面 命令启动mysql 使用 docker compose up -d (启动容器命令，一定要在需要启动容器目录下面去执行这个命令 都在他会把这个目录下面所有的容器都会启动)
-d 代表后台运行
问题：
这里可能会遇到没有权限的情况
[root@localhost ~]# docker compose up -d-bash: /usr/local/bin/docker-compose: 权限不够解决方法
chmod +x /usr/local/bin/docker-compose执行后等待安装完成
[root@localhost ~]# docker-compose up -dPulling mysql (mysql:5.7)...5.7: Pulling from library/mysqle048d0a38742: Pull completec7847c8a41cb: Pull complete351a550f260d: Pull complete8ce196d9d34f: Pull complete17febb6f2030: Pull completed4e426841fb4: Pull completefda41038b9f8: Pull completef47aac56b41b: Pull completea4a90c369737: Pull complete97091252395b: Pull complete84fac29d61e9: Pull completeDigest: sha256:8cf035b14977b26f4a47d98e85949a7dd35e641f88fc24aa4b466b36beecf9d6Status: Downloaded newer image for mysql:5.7Creating mysql ... done使用docker命令看一下mysql容器是否已经启动 docker ps
[root@localhost ~]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES3023aafe6fff mysql:5.7 "docker-entrypoint.s…" 4 seconds ago Up 2 seconds 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp mysql如果要打命令我们可以进入容器内
docker exec -it 容器名 /bin/bashbash-4.2# mysql -u root -pchenmysql: [Warning] Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.

在windows下我们也是可以正常连接到mysql的
如果在外部连接不上可以关闭下防火墙
systemctl stop firewalld来源地址：https://blog.csdn.net/cjj2006/article/details/129246910
