docker安装oralce11g

windows安装的oracle不知道出什么问题了，出现诡异异常，到最后起数据库实例的时候就一直报错，就用docker安装一个

1、拉取 docker 镜像：
命令：

[root@iZbp145axkc98giot5b448Z ~]# docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
Using default tag: latest
Trying to pull repository registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g ...
latest: Pulling from registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
ed5542b8e0e1: Pull complete
a3ed95caeb02: Pull complete
1e8f80d0799e: Pull complete
Digest: sha256:4c12b98372dfcbaafcd9564a37c8d91456090a5c6fb07a4ec18270c9d9ef9726
Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g:latest

该镜像由阿里云提供，比较大，可能需要下载一会，等待下载即可。
2、查看 docker 镜像：
命令：

root@iZbp145axkc98giot5b448Z ~]# docker images
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE

3、进入容器修改账户密码
3.1 检查容器是否运行成功
命令：

[root@iZbp145axkc98giot5b448Z ~]# docker ps -l
CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS              PORTS                    NAMES
188c85d4d5ca        registry.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   45 seconds ago      Up 13 seconds       0.0.0.0:1521->1521/tcp   oracle

3.2 进入容器
命令：

[root@iZbp145axkc98giot5b448Z ~]# docker exec -it 188c85d4d5ca  bash
[oracle@188c85d4d5ca /]$ pwd
/
[oracle@188c85d4d5ca /]$ ls -l
total 84

dr-xr-xr-x  13 root root     0 Apr  8 14:20 sys

drwxr-xr-x  13 root root  4096 Aug 23  2014 usr
drwxr-xr-x   1 root root  4096 Aug 23  2014 var

3.3 切换回root用户
su - root 密码helowin

oracle@188c85d4d5ca dbhome_2]$ su - root
Password:
[root@188c85d4d5ca ~]# vi /etc/profile

3.4 编辑环境变量 vi /etc/profile 在文件的末尾添加一下内容
添加内容：

export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

注意：按i进入编辑模式，输入上述命令后，按ESC键退出编辑模式，再输入:wq保存退出

3.5 使得修改生效
命令：source /etc/profile

3.6 进入容器（此处的id就是第一个命令下的id），加载一下用户环境变量，进入容器后，自动是oracle用户

使用sysdba 连接oracle
命令：

[root@188c85d4d5ca ~]# su - oracle
[oracle@188c85d4d5ca ~]$  sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 10 20:55:59 2020

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

SQL> conn /as sysdba
Connected.

连接成功后，修改system用户的密码
命令:

SQL> alter user system identified by system;

User altered.

SQL> alter user sys identified by sys;

User altered.

SQL>

退出编辑sql命令:exit
