在Docker中搜索并下载MySQL8.0.x的最新版本 下载好后在Images中就可以看到MySQL的镜像了 通过下面的命令也可以查看docker images启动镜像使用下面的命令就可以启动镜像了docker run -itd --name mysql8.0.34 -p 3306:3306 --privilegedtrue -e MYSQL_ROOT_PASSWORDroot mysql:8.0.34解释 -i 即使没有连接也要保持标准输入保持打开状态一般与 -t 连用-t分配一个伪tty一般与 -i 连用-d在后台运行容器并且打印容器id–name镜像名称-p端口映射容器内端口3306映射到容器外的3306上–privileged为容器提供权限-e设置镜像参数 MYSQL_ROOT_PASSWORD设置root用户的密码 此时在容器内部已经初始化好了MySQL了但是一般来说我们需要把MySQL的配置文件和datadir挂在到docker外部所以我们还需要后面的步骤创建config和data目录mkdir -p /Users/xxx/docker/data/mysql8.0.34/{config,data}切换到config目录cd /Users/xxx/docker/data/mysql8.0.34/config把config文件从镜像内部复制出来docker cp mysql8.0.34:/etc/my.cnf ./确认config文件cat my.cnf# For advice on how to change settings please see

# Remove leading # to turn on a very important data integrity option: logging

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
