CentOS 7.7 1908 使用 Docker 安裝 Oracle 11g

---

1. 使用 Docker 創建第二個 Oracle 11g（oracle_11g_2）：

   docker run --restart=always -p 11522:1522 --name oracle_11g_2 -d registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

2. 查看運行鏡像：

   docker ps -a

   運行結果：

   [root@localhost ~]# docker ps -a
   CONTAINER ID        IMAGE                                                  COMMAND                  CREATED             STATUS              PORTS                               NAMES
   843281daf217        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   3 minutes ago       Up 3 minutes        1521/tcp, 0.0.0.0:11522->1522/tcp   oracle_11g_2
   a89bffd7afe8        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   22 hours ago        Up 4 minutes        0.0.0.0:11521->1521/tcp             oracle_11g
   [root@localhost ~]# 
   

3. 開通端口：

   firewall-cmd --zone=public --add-port=11522/tcp --permanent
   firewall-cmd --reload
   firewall-cmd --list-all

4. 進入 oracle_11g_2：

   docker exec -it oracle_11g_2 bash

5. 執行結果：

   [root@localhost ~]# docker exec -it oracle_11g_2 bash
   [oracle@6f0d3d29babc /]$ 
   

6. 查看監聽：

   lsnrctl status

   運行結果：

   [oracle@6f0d3d29babc /]$ lsnrctl status
   bash: lsnrctl: command not found
   [oracle@6f0d3d29babc /]$ 
   

   刷新環境變量：

   source /home/oracle/.bash_profile

   再次查看監聽：

   [oracle@6f0d3d29babc /]$ lsnrctl status

   The command completed successfully
   [oracle@6f0d3d29babc /]$ 
   

7. 修改 listener.ora 端口：

   vi /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin/listener.ora

   1、將 EXTPROC1521 修改爲 EXTPROC1522
   2、將 PORT = 1521 修改爲 PORT = 1522

   # listener.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin/listener.ora
   # Generated by Oracle configuration tools.
   
   LISTENER =
     (DESCRIPTION_LIST =
       (DESCRIPTION =
         (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
         (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1522))
       )
     )
   
   ADR_BASE_LISTENER = /home/oracle/app/oracle
   

8. 修改 tnsnames.ora：

   vi /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin/tnsnames.ora

   將 PORT = 1521 修改爲 PORT = 1522

   # tnsnames.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin/tnsnames.ora
   # Generated by Oracle configuration tools.
   
   LISTENER_HELOWIN =
     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
   
   
   HELOWIN =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
       (CONNECT_DATA =
         (SERVER = DEDICATED)
         (SERVICE_NAME = helowin)
       )
     )

9. 重啓監聽：

   lsnrctl start

   運行結果：

   [oracle@6f0d3d29babc /]$ lsnrctl start

10. 重啓 oracle：
    1. 使用 dba 登錄 Oracle：

       sqlplus / as sysdba

    2. 關閉數據庫：

       shutdown immediate;

    3. 開啓數據庫：

       startup;

11. 遠程連接：
