CentOS 7.7 1908 使用 Docker 安装 Oracle 11g

1. 安装 Oracle：

   docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

2. 查看已安装的镜像：

   docker images

   查看结果：

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

3. 创建并允许 Oracle：

   docker run --restart=always -p 11521:1521 --name oracle_11g -d registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

4. 查看已创建、运行的镜像：

   docker ps -a

   运行结果：

   [root@localhost ~]# docker ps -a
   CONTAINER ID        IMAGE                                                  COMMAND                  CREATED             STATUS              PORTS                     NAMES
   eaa6746586a6        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   53 seconds ago      Up 45 seconds       0.0.0.0:11521->1521/tcp   oracle_11g
   [root@localhost ~]#

5. 开放端口：

   firewall-cmd --zone=public --add-port=11521/tcp --permanent
   firewall-cmd --reload
   firewall-cmd --list-all

6. 登录 Docker 中 Oracle 软件所在的 oracle 用户：

   docker exec -it oracle_11g bash

   运行结果：

   [root@localhost ~]# docker exec -it oracle_11g bash
   [oracle@eaa6746586a6 /]$ 

7. 查看 oracle 用户：

   id oracle

   运行结果：

   [oracle@eaa6746586a6 /]$ id oracle
   uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba),502(oper)
   [oracle@eaa6746586a6 /]$ 
   

8. 查看监听：

   lsnrctl status

   运行结果：

   [oracle@eaa6746586a6 /]$ lsnrctl status
   bash: lsnrctl: command not found
   [oracle@eaa6746586a6 /]$ 
   

   刷新环境变量：

   source /home/oracle/.bash_profile

   再次查看监听：

   [oracle@eaa6746586a6 /]$ lsnrctl status
