docker安裝Oracle11g數據庫

最近公司項目需要用到oracle數據庫，爲方面同事開發，於是在公司阿里雲服務器上用docker安裝了一個oracle11g，給同事開發測試使用。
1、下載oracle11g的鏡像文件
這裏我使用的鏡像文件是：registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g，這個鏡像文件有6.85G這麼大，下載需要幾分鐘的時間。

[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker images
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE
registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   latest              3fa112fd3642        4 years ago         6.85GB

2、創建運行oracle容器

[root@iZbp13sno1lc2yxlhjc4b3Z ~]#docker run -d -p 1521:1521 --name oracle11g registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

3、配置oracle
進入oracle容器，配置環境變量。
分別在在/etc/profile和/home/oracle/.bashrc文件末尾添加環境變量。
在/etc/profile設置oracle環境變量：

[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker exec -it oracle11g bash
[oracle@753d0436c2f1 /]$ vi /etc/profile
# /etc/profile
...
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

在/home/oracle/.bashrc設置oracle環境變量：

[oracle@753d0436c2f1 /]$ vi /home/oracle/.bashrc
# .bashrc
...
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

測試數據庫連接：

[oracle@753d0436c2f1 /]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Thu May 14 20:57:07 2020

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

SQL> conn / as sysdba
Connected.
SQL> 

4、修改oracle用戶密碼
修改sys、system等管理員賬戶密碼

SQL> alter user system identified by system;

User altered.

SQL> alter user sys identified by sys;

User altered.

SQL> 

查看oracle數據庫狀態、實例名等信息：

[oracle@753d0436c2f1 /]$ lsnrctl status

根據狀態信息可知，實例名爲：helowin。

5、PLSQL客戶端連接
用戶：sys，密碼：sys，數據庫：你的IP地址/helowin，以sysdba角色登錄即可。
