查看系統內核
[root@localhost /]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
2 虛擬機拉取鏡像
此處資源獲取在虛擬機中進行，完成后上傳到服務器安裝
2.1 拉取mysql5.7鏡像
[root@localhost /]# docker pull mysql:5.7
2.2 導出鏡像
[root@localhost /]# docker save -o /opt/module/software/jingxiang/mysql57.tar mysql:5.7
3 服務器加載鏡像
將提供的docker文件夾上傳到服務器的 /opt/module/software/jingxiang 目錄下
3.1 導入Mysql鏡像
[root@localhost /]# docker load -i /opt/module/software/jingxiang/mysql57.tar

3.2 創建容器
[root@localhost /]# docker run -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7
1fcf644fb24c4731f70ca66edc96847452e898de7612de05b4dd188b3965883c
run 運行一個docker容器
--name 后面這個是生成的容器的名字mysql
-p 3306:3306 表示這個容器中使用3306(第二個)映射到本機的端口號也為3306(第一個)
-e MYSQL_ROOT_PASSWORD=123456 初始化root用戶的密碼
-d 表示使用守護進程運行，即服務掛在后臺
[root@localhost docker]# docker ps
