最近使用云服务器，学习一下 Docker，今天学着使用 Docker 安装 MySQL。首先，从阿里云的 Docker Hub 上 pull 一个 MySQL 的 image.

[CentOS@linuxidc~]$ docker pull registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7
5.7: Pulling from acs-sample/mysql
d4bce7fd68df: Pull complete

Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7

查看下载镜像，就会看到已经有了

[centos@linuxidc~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test/Ubuntu v1.0 523e7db0e264 11 minutes ago 98.3MB
ubuntu latest dd6f76d9cc90 7 days ago 122MB
hello-world latest 725dcfab7d63 8 days ago 1.84kB
registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql 5.7 ec7e75e5260c 23 months ago 360MB

名字太长，修改为短的 tag

[centos@linuxidc~]$ docker tag registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7 mysql:5.7
[centos@linuxidc~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test/ubuntu v1.0 523e7db0e264 12 minutes ago 98.3MB
ubuntu latest dd6f76d9cc90 7 days ago 122MB
hello-world latest 725dcfab7d63 8 days ago 1.84kB
mysql 5.7 ec7e75e5260c 23 months ago 360MB
registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql 5.7 ec7e75e5260c 23 months ago 360MB

根据镜像创建容器

[centos@linuxidc~]$ docker create -it mysql:5.7
62c975b37ad25b03914eb61e05088019f37ff9cb049a682ac02f20fac1761a4d

启动 MySQL 容器

[centos@linuxidc~]$ docker run –name mysqlserver -e MYSQL_ROOT_PASSWORD=sgcc -d -i -p 3306:3306 mysql:5.7
2a7a85124400be6fd47e0d97cf5d602456b1db1a11c6331747fe662481eea537
[centos@linuxidc~]$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2a7a85124400 mysql:5.7 “/entrypoint.sh my…” 9 seconds ago Up 8 seconds 0.0.0.0:3306->3306/tcp mysqlserver
188099665d1e ubuntu:latest “/bin/bash” 23 hours ago Up 23 hours angry_spence

进入 MySQL 终端

[centos@liujun ~]$ docker exec -it 2a7a85124400 /bin/bash
root@2a7a85124400:/# mysql -h 127.0.0.1 -u root -p
