docker部署oracle12c

概述

本文指导如何使用oracle的官方镜像安装部署oracle12c

操作步骤

注册docker账号

oracle12的官方镜像需要有docker账号才能有权限进行下载

docker 登录

使用docker login，通过docker账号登录到dockerhub

# docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.

Login Succeeded

运行Oracle

为了使外部可以通过端口进行访问内部数据库，以及持久化保存oracle数据，这里将容器的1521端口以及oracle的数据卷映射到宿主机。

官方提供镜像文件还有很多可选的参数配置，可以通过docker hub进行了解和使用

# docker run -d -it --name oracleDB -v /opt/Projects/oracle12c/DBData:/ORCL -p 41521:1521 store/oracle/database-enterprise:12.2.0.1

使用Oracle

通过docker exec 可以进入到容器内部，这样就可以使用容器内部的数据库了

# docker exec -it oracleDB /bin/bash

$ sqlplus / as sysdba

总结

通过docker镜像部署oracle12c是不是很方便，不用去考虑那么多参数的设置和环境变量，官方就已经通过容器封装好了一个镜像了，这就是容器的便利之处。
