CentOS 7.7 1908 使用 Docker 中的數據庫增加監聽端口與端口映射

1. 查看 docker 容器目錄

   docker info | grep 'Docker Root Dir'

   運行結果：

   [root@localhost ~]# docker info | grep 'Docker Root Dir'
     WARNING: You're not using the default seccomp profile
   WARNING: bridge-nf-call-iptables is disabled
   WARNING: bridge-nf-call-ip6tables is disabled
   Docker Root Dir: /data/docker
   [root@localhost ~]# 

   安裝目錄爲：/data/docker
    
2. 查看已創建的容器：

   docker ps -a

   運行結果：

   [root@localhost ~]# docker ps -a
   CONTAINER ID        IMAGE                                                  COMMAND                  CREATED             STATUS              PORTS                                              NAMES
   a89bffd7afe8        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   3 days ago          Up 8 minutes        0.0.0.0:11521->1521/tcp                            oracle_11g
   [root@localhost ~]# 
   

   oracle_11g 唯一ID爲：a89bffd7afe8，唯一ID是安裝目錄的前 12 位
    
3. 進入 oracle_11g 安裝目錄：
   docker 容器在安裝目錄中的 containers 文件夾下：
   根據上述條件，進入安裝目錄：

   cd /data/docker/containers/a89bffd7afe8ed7168bc1ba641f7327ba1f5da662563ba335f69bad8dadee038/

4. 查看 vim 版本：

   vim -v

   若未安裝 vim，請運行命令安裝：

   yum -y install vim

5. 通知 docker：

   systemctl stop docker

6. 編輯 hostconfig.json 文件：

   vim hostconfig.json

   輸入命令，回車進行 JSON 格式化：

   :%!python -m json.tool

   找到：

   "PortBindings": {
   	"1521/tcp": [
   		{
   			"HostIp": "",
   			"HostPort": "11521"
   		}
   	]
   }

   新增內部端口 1158，外部端口 11158：

   "PortBindings": {
   	"1521/tcp": [
   		{
   			"HostIp": "",
   			"HostPort": "11521"
   		}
   	],
   	"1522/tcp": [
   		{
   			"HostIp": "",
   			"HostPort": "11522"
   		}
   	]
   }

7. 編輯 config.v2.json 文件：

   vim config.v2.json

   輸入命令，回車進行 JSON 格式化：

   :%!python -m json.tool

   在 "ExposedPorts" 中增加內部端口 1522：

   "ExposedPorts": {
   	"1521/tcp": {},
   	"1522/tcp": {}
   },

8. 啓動 docker：

   systemctl start docker

9. 查看已創建的容器：

   docker ps -a

   運行結果：

   [root@localhost a89bffd7afe8ed7168bc1ba641f7327ba1f5da662563ba335f69bad8dadee038]# docker ps -a
   CONTAINER ID        IMAGE                                                  COMMAND                  CREATED             STATUS              PORTS                                              NAMES
   a89bffd7afe8        registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   "/bin/sh -c '/home..."   3 days ago          Up 4 seconds        0.0.0.0:11521->1521/tcp, 0.0.0.0:11522->1522/tcp   oracle_11g
   [root@localhost a89bffd7afe8ed7168bc1ba641f7327ba1f5da662563ba335f69bad8dadee038]#

10. 開通本機（非 docker）11522端口：

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

11. 進入 oracle11g：

    docker exec -it oracle_11g bash

    執行結果：

    [root@localhost a89bffd7afe8ed7168bc1ba641f7327ba1f5da662563ba335f69bad8dadee038]# docker exec -it oracle_11g bash
    [oracle@a89bffd7afe8 /]$ 

12. 編輯 tnsnames.ora：

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

    由：

    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
          (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
        )
      )
    
    ADR_BASE_LISTENER = /home/oracle/app/oracle
    

    新增端口 1522：

    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
          (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
          (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1522))
        )
      )
    
    ADR_BASE_LISTENER = /home/oracle/app/oracle
    

13. 重啓監聽：
    停止監聽：

    lsnrctl stop

    運行如下：

    [oracle@a89bffd7afe8 /]$ lsnrctl stop
