liunx安装oracle11G

1、拉取 docker 镜像：
[root@localhost ~]# docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
Using default tag: latest
latest: Pulling from 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、用 docker images 命令查看镜像
[root@localhost ~]# docker images
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE
registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   latest              3fa112fd3642        3 years ago         6.85GB
运行镜像
docker run -d -p 1521:1521 --name oracle registry.aliyuncs.com/helowin/oracle_11g
3、进入容器修改账号密码
3.1，检查容器是否运行成功

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE                                      COMMAND                  CREATED              STATUS              PORTS                    NAMES
a151f9478f94        registry.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home/o…"   About a minute ago   Up 30 seconds       0.0.0.0:1521->1521/tcp   oracle
启动oracle

[root@localhost ~]# docker start oracle
3.2，进入容器：docker exec -it oracle bash

[root@localhost ~]# docker exec -it oracle bash
[oracle@a151f9478f94 /]$
3.3，切换回root用户

[oracle@a151f9478f94 /]$ exit
exit
[root@localhost ~]# 
3.4，编辑环境变量 vi /etc/profile 在文件的末尾添加一下内容

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）

3.6，使得修改生效： 

[root@localhost ~]# source /etc/profile
3.7，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

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS              PORTS                    NAMES
a151f9478f94        registry.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home/o…"   3 hours ago         Up 3 hours          0.0.0.0:1521->1521/tcp   oracle
 
[root@localhost ~]# docker exec -it a151f9478f94 /bin/bash
[oracle@a151f9478f94 /]$ source ~/.bash_profile
 

[oracle@a151f9478f94 /]$ sqlplus /nolog
