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 docker.io/elasticsearch latest 5acf0e8da90b 18 months ago 486 MB docker.io/containerize/elastichd latest c2202f76db37 2 years ago 28.1 MB registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g latest 3fa112fd3642 4 years ago 6.85 GB [root@iZbp145axkc98giot5b448Z ~]# docker run -d -p 1521:1521 --name oracle registry.aliyuncs.com/helowin/oracle_11g Unable to find image 'registry.aliyuncs.com/helowin/oracle_11g:latest' locally Trying to pull repository registry.aliyuncs.com/helowin/oracle_11g ... latest: Pulling from registry.aliyuncs.com/helowin/oracle_11g ed5542b8e0e1: Already exists a3ed95caeb02: Already exists 1e8f80d0799e: Already exists Digest: sha256:4c12b98372dfcbaafcd9564a37c8d91456090a5c6fb07a4ec18270c9d9ef9726 Status: Downloaded newer image for registry.aliyuncs.com/helowin/oracle_11g:latest 188c85d4d5ca044e90f76270bc4ac97d4488c0c2ff526148122c5a1481da6a30
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 2 root root 4096 Dec 3 2013 bin dr-xr-xr-x 4 root root 4096 Dec 3 2013 boot drwxr-xr-x 5 root root 340 Apr 10 20:48 dev drwxr-xr-x 1 root root 4096 Apr 10 20:47 etc drwxr-xr-x 1 root root 4096 Aug 29 2014 home dr-xr-xr-x 8 root root 4096 Aug 23 2014 lib dr-xr-xr-x 7 root root 12288 Aug 23 2014 lib64 drwxr-xr-x 2 root root 4096 Sep 23 2011 media drwxr-xr-x 2 root root 4096 Sep 23 2011 mnt drwxr-xr-x 2 root root 4096 Sep 23 2011 opt dr-xr-xr-x 113 root root 0 Apr 10 20:48 proc dr-xr-x--- 3 root root 4096 Aug 26 2014 root drwxr-xr-x 3 root root 4096 Apr 10 20:48 run dr-xr-xr-x 2 root root 4096 Aug 23 2014 sbin drwxr-xr-x 2 root root 4096 Sep 23 2011 selinux drwxr-xr-x 2 root root 4096 Sep 23 2011 srv dr-xr-xr-x 13 root root 0 Apr 8 14:20 sys drwxrwxrwt 1 root root 4096 Apr 10 20:48 tmp 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
