原 【DB宝76】在Docker中只需2步即可拥有Oracle 21c环境
👉 本文共约1450个字，系统预计阅读时间或需6分钟。
简介
Oracle Database 21c 于8月13日发布，首先发布的是Linux版本，可以从官方网站下载。21c整合了原计划2020年发布的 20c 版本，原计划 2021年上半年发布，因为疫情等原因推迟了发布。而且据悉，22c 版本号可能取消，23c将是下一个可见版本。

单实例只需要下载LINUX.X64_213000_db_home.zip即可。
当然，我们本文不教大家如何安装Oracle。 我们只需要看下面的内容即可！！！
一、从Docker Hub或阿里云镜像下载小麦苗上传的镜像文件
- 小麦苗的Docker Hub的地址：https://hub.docker.com/u/lhrbest
- Oracle 21c DB的地址：https://hub.docker.com/r/lhrbest/oracle21c_ee_db_21.3.0.0/tags
1 2 3 4 5 6 | # 从Docker hub下载，网络不好时，一般比较慢 docker pull lhrbest/oracle21c_ee_db_21.3.0.0 # 可以选择从阿里云下载 docker pull registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle21c_ee_db_21.3.0.0 # 从阿里云下载后可以tag成如下形式 docker tag registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle21c_ee_db_21.3.0.0 lhrbest/oracle21c_ee_db_21.3.0.0 |
镜像大概5.5G左右，解压后大约16G左右，所以请保留充足的空间。执行过程如下：
1 2 3 | [root@docker35 ~]# docker images | grep 21c lhrbest/oracle21c_ee_db_21.3.0.0 latest 86933671efb6 About an hour ago 16.3GB registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle21c_ee_db_21.3.0.0 latest 86933671efb6 About an hour ago 16.3GB |
二、创建容器并启动数据库
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | # 1、创建容器 docker run -d --name lhroracle21c -h lhroracle21c \ -p 5510:5500 -p 55100:5501 -p 1530:1521 -p 3400:3389 \ -v /sys/fs/cgroup:/sys/fs/cgroup \ --privileged=true lhrbest/oracle21c_ee_db_21.3.0.0 \ /usr/sbin/init # 2、进入容器 docker exec -it lhroracle21c bash # 3、启动监听和数据库 su - oracle sas startup lsnrctl start |
执行过程如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 | [root@docker35 ~]# docker run -d --name lhroracle21c -h lhroracle21c \ > -p 5510:5500 -p 55100:5501 -p 1530:1521 -p 3400:3389 \ > -v /sys/fs/cgroup:/sys/fs/cgroup \ > --privileged=true lhrbest/oracle21c_ee_db_21.3.0.0 \ > /usr/sbin/init c5c16e24b308fb5120811e2e0edbeceb11a9a292ae991840097e63e385d6517f [root@docker35 ~]# [root@docker35 ~]# docker exec -it lhroracle21c bash [root@lhroracle21c /]# su - oracle Last login: Mon Aug 16 14:05:17 CST 2021 on pts/0 [oracle@lhroracle21c ~]$ sas SQL*Plus: Release 21.0.0.0.0 - Production on Mon Aug 16 15:48:53 2021 Version 21.3.0.0.0 Copyright (c) 1982, 2021, Oracle.

3.2 创建数据库
我们也可以自己创建自己需要的数据库，如下所示，创建了一个cdb的数据库，dbname和sid都是lhrdb：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | dbca -silent -createDatabase -templateName General_Purpose.dbc -responseFile NO_VALUE \ -gdbname lhrdb -sid lhrdb \ -createAsContainerDatabase TRUE \ -numberOfPDBs 1 \ -pdbName pdb2 \ -pdbAdminPassword lhr \ -sysPassword lhr -systemPassword lhr \ -datafileDestination '/u01/app/oracle/oradata' \ -recoveryAreaDestination '/u01/app/oracle/flash_recovery_area' \ -redoLogFileSize 50 \ -storageType FS \ -characterset AL32UTF8 -nationalCharacterSet AL16UTF16 \ -totalMemory 1024 \ -databaseType OLTP \ -emConfiguration NONE |
