Status: Downloaded newer image for mysql:8.0

使用docker images可以查看已获取的镜像

[root@iZuf68t6hada0ayijajs45Z docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               8.0                 e3fcc9e1cc04        5 hours ago         544MB
启动
[root@iZuf68t6hada0ayijajs45Z svdb]# docker run --name mysql --restart=always \
>     -v /data/svdb/mysql/conf/my.cnf:/etc/mysql/my.cnf \
>     -v /data/svdb/mysql/data:/var/lib/mysql \
>     -p 3317:3306 \
>     -e MYSQL_ROOT_PASSWORD="root" \
>     -e TZ=Asia/Shanghai \
>     -d mysql:8.0 --lower-case-table-names=1

1、-name mysql ： 给Mysql容器起一个别名
2、-restart=always：开机启动
3、-v：将容器的文件挂载到宿主目录，避免以后在卸载docker的时候，数据丢失。
如：-v /data/svdb/mysql/conf/my.cnf:/etc/mysql/my.cnf 是将容器的/etc/mysql/my.cnf 挂载到主机的/data/svdb/mysql/conf/my.cnf
4、-e MYSQL_ROOT_PASSWORD：设置密码
5、-p 3317:3306：mysql端口映射到主机的3317端口
6、-d mysql:8.0：后台运行容器
7、–lower-case-table-names=1一定要加，mysql8.0关方规定只有在初始化的时候给与配置，后续不管在my.cnf还是重新docker run --lower都无效（重新docker run --lower必须保证/var/lib/mysql仓库是干净的才可以，不然出错）

进入Mysql

先进入mysql镜像，在登入mysql.

[root@iZuf68t6hada0ayijajs45Z svdb]# docker exec -it mysql /bin/bash
root@f2c3eb8f47c2:/#
