前言

docker是一个用Go语言实现的开源项目，可以让我们方便的创建和使用容器，docker将程序以及程序所有的依赖都打包到docker container，这样你的程序可以在任何环境都会有一致的表现，这里程序运行的依赖也就是容器就好比集装箱，容器所处的操作系统环境就好比货船或港口，程序的表现只和集装箱有关系(容器)，和集装箱放在哪个货船或者哪个港口(操作系统)没有关系。

一、下载docker静态二进制存档

要根据硬件平台下载以免造成不兼容
https://download.docker.com/
根据自己的需求安装对应的版本（我这里选择的是docker-20.10.7）
https://download.docker.com/linux/static/stable/x86_64/docker-20.10.7.tgz

将下载好的的包上传到对应服务器
并解压 tar -zxvf docker-20.10.7.tgz
解压完的文件为docker

[root@v-ct-jy-czzp-app-160 opt]# tar -zxvf docker-20.10.7.tgz 

二、将解压完的二进制文件移到可执行文件目录下

[root@v-ct-jy-czzp-app-160 opt]# mv docker/* /usr/bin/

三、配置docker.service

[root@v-ct-jy-czzp-app-160 opt]# vim /usr/lib/systemd/system/docker.service

将以下内容填入

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s[Install]
WantedBy=multi-user.target

四、启动dockerd服务

[root@v-ct-jy-czzp-app-160 opt]# systemctl daemon-reload
[root@v-ct-jy-czzp-app-160 opt]# systemctl start docker.service
[root@v-ct-jy-czzp-app-160 opt]# docker info

将docker设置为开机自启动

[root@v-ct-jy-czzp-app-160 opt]# systemctl enable docker

五、在有网络的环境生成Oracle11g镜像并导入

5.1下载镜像Oracle11g镜像

注意最好使用的服务器要和内网机器系统兼容否则镜像导入时会报错

[root@summer summer]# 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
registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g:latest

5.2将镜像打包

[root@summer summer]#docker save nginx:latest > oracle11g.tar

5.3将镜像导入

[root@v-ct-jy-czzp-app-160 opt]# docker load -i oracle11g.tar 

六、docker安装oracle11g

6.1启动镜像

[root@v-ct-jy-czzp-oth-02 ~]# docker run -d --name oracle -p 1521:1521 registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

6.2宿主机创建文件夹

[root@v-ct-jy-czzp-oth-02 ~]# mkdir -p /opt/oracle/
[root@v-ct-jy-czzp-oth-02 ~]# mkdir -p /opt/oracle/flash_recovery_area/

6.3拷贝数据库文件至宿主机

[root@v-ct-jy-czzp-oth-02 ~]# mkdir -p /opt/oracle/
[root@v-ct-jy-czzp-oth-02 ~]# mkdir -p /opt/oracle/flash_recovery_area/
[root@v-ct-jy-czzp-oth-02 ~]# docker ps -a
CONTAINER ID   IMAGE                                                  COMMAND                  CREATED          STATUS          PORTS                                       NAMES
149b2d1a4d64   registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home/o…"   26 seconds ago   Up 20 seconds   0.0.0.0:1521->1521/tcp, :::1521->1521/tcp   oracle
[root@v-ct-jy-czzp-oth-02 ~]# docker cp 149b2d1a4d64:/home/oracle/app/oracle/oradata /opt/oracle/oradata
[root@v-ct-jy-czzp-oth-02 ~]# docker cp 149b2d1a4d64:/home/oracle/app/oracle/flash_recovery_area/helowin /opt/oracle/flash_recovery_area/helowin
[root@v-ct-jy-czzp-oth-02 ~]# chmod -R 777 /opt/oracle/

6.4停止和删除容器

[root@v-ct-jy-czzp-oth-02 ~]# docker stop 149b2d1a4d64
149b2d1a4d64
[root@v-ct-jy-czzp-oth-02 ~]# docker rm 149b2d1a4d64
149b2d1a4d64

6.5启动docker容器（映射数据文件）

[root@v-ct-jy-czzp-oth-02 ~]# docker run -d --name oracle_llg -p 1521:1521 --privileged=true -v /opt/oracle/oradata:/home/oracle/app/oracle/oradata -v /opt/oracle/flash_recovery_area/helowin:/home/oracle/app/oracle/flash_recovery_area/helowin registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

6.6执行并完成基础设置

6.6.1 进入容器

[root@v-ct-jy-czzp-oth-02 ~]# docker ps
CONTAINER ID   IMAGE                                                  COMMAND                  CREATED          STATUS          PORTS                                       NAMES
640d85e4800c   registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home/o…"   10 seconds ago   Up 10 seconds   0.0.0.0:1521->1521/tcp, :::1521->1521/tcp   oracle_llg
[root@v-ct-jy-czzp-oth-02 ~]# docker exec -it 640d85e4800c /bin/bash

6.6.2加载环境变量

[oracle@640d85e4800c /]$ source /home/oracle/.bash_profile
[oracle@640d85e4800c /]$ su root 
Password: 
#密码：helowin
[root@640d85e4800c /]# vi /etc/profile
#在末尾添加export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2export ORACLE_SID=helowinexport PATH=$ORACLE_HOME/bin:$PATH
#刷新配置
[root@640d85e4800c /]# source /etc/profile
[root@640d85e4800c /]# su oracle

6.6.3登录

[oracle@47badc5bb7c4 /]$ sqlplus /nologSQL*Plus: Release 11.2.0.1.0 Production on Fri Mar 3 19:42:31 2023Copyright (c) 1982, 2009, Oracle.  All rights reserved.SQL> connect /as sysdba
Connected.

6.6.4修改默认用户密码

SQL> alter user system identified by system;User altered.SQL> alter user sys identified by sys;User altered.SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;Profile altered.SQL>

6.6.5创建用户并指定表空间，授权

SQL> create user summer IDENTIFIED BY 123456 default tablespace test;User created.SQL> grant connect,resource,dba to summer;Grant succeeded.SQL>

名称	参数
IP	宿主机ip
端口	1521
SID	helowin
账号	summer
密码	123456

6.7 修改SID

原来SID为helowin，先需要修改为orcl

6.7.1关闭数据库

[oracle@47badc5bb7c4 /]$ sqlplus /nologSQL*Plus: Release 11.2.0.1.0 Production on Wed Nov 4 01:00:41 2020Copyright (c) 1982, 2009, Oracle.  All rights reserved.SQL> connect /as sysdba
Connected.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

6.7.2修改环境变量

[oracle@47badc5bb7c4 /]$ vi /home/oracle/.bash_profile
#更改
ORACLE_SID=orcl;export ORACLE_SID
[oracle@47badc5bb7c4 /]$ cat /etc/oratab
orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_2:Y

总结

就此如何快速在内网环境搭建一个Oracle数据库搭建完成，感谢支持
