docker-compose安装oracle11g并持久化

2022/8/6 2:24:13

本文主要是介绍docker-compose安装oracle11g并持久化,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

步骤:

  1. 先不挂载宿主机目录启动oracle实例
  2. 将docker内容文件拷贝到宿主机中
  3. 给宿主机的文件夹赋权限
  4. 修改docker-compose.yml 文件挂载上宿主机目录
  5. 重启docker服务
  6. 重启报错,进入docker服务解决错误。每次重启都需要此步操作!!!

编写docker-compose 启动实例

docker-compose.yml

version: '3.1'
services:
  master:
    image: registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
    container_name: oracle
    privileged: true
    ports:
      - 1521:1521

启动成功,进入容器

docker-compose up -d
docker exec -it oracle bash

配置环境,并创建用户

cd /home/oracle                                           # 进入到 oracle 用户目录
source .bash_profile                                      # 加载 oracle 环境变量
$PATH                                                     # 查看 oracle 环境变量是否生效
sqlplus / as sysdba                                       # 连接 oracle 数据库
alter user system identified by oracle;                   # 修改 DBA 账号的密码
alter user sys identified by oracle;                      # 修改 DBA 账号的密码
alter profile default limit password_life_time unlimited; # 设置密码为永不过期
create user test identified by oracle;                    # 创建一个 test 用户,密码 oracle
select * from dba_users t where t.username = 'TEST';      # 查询用户是否创建成功
grant connect, resource to test;                          # 给用户授予连接和数据权限

相关配置(可省略)

grant select on V_$session to test;
grant select on V_$sesstat to test;
grant select on V_$statname to test;
show parameter deferred_segment_creation;          -- 查看是否启用 true 为启动
alter system set deferred_segment_creation=false;  -- 修改为不启用
show parameter deferred_segment_creation;          -- 查看是否修改成功 false 未启用

plsql 连接

oracle_11g =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.168.1.***)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = helowin)
    )
  )

数据持久化

docker cp oracle:/home/oracle/app/oracle/oradata/helowin /usr/local/docker/oracle/helowin
cd /usr/local/docker/oracle
chown -R 500.500 ./helowin  # 500 500 是容器内 oracle 组合用户的 id

关闭容器:

docker-compose down

修改docker-compose.yml

version: '3.1'
services:
  master:
    image: registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
    container_name: oracle
    privileged: true
    ports:
      - 1521:1521
    # 新增以下信息
    volumes:
      - ./helowin:/home/oracle/app/oracle/oradata/helowin

查看日志:docker logs -f oracle,我们发现了一个错误,这是由于 oracle 为了数据安全,添加的版本验证

/home/oracle/app/oracle/product/11.2.0/dbhome_2
Processing Database instance "helowin": log file /home/oracle/app/oracle/product/11.2.0/dbhome_2/startup.log

进入容器内,解决错误,每次重启都需要此部操作!!!

docker exec -it oracle bash
cd /home/oracle              # 进入到 oracle 用户目录
source .bash_profile         # 加载 oracle 环境变量(每次进入容器都要加载配置文件)
 
# 删除新生成的版本控制文件,将数据卷中的版本控制文件复制为新生成的版本控制文件
rm -rf /home/oracle/app/oracle/flash_recovery_area/helowin/control02.ctl
cp /home/oracle/app/oracle/oradata/helowin/control01.ctl /home/oracle/app/oracle/flash_recovery_area/helowin/control02.ctl
 
sqlplus / as sysdba          # 以 dba 身份连接 oracle 数据库
shutdown immediate           # 关闭数据库实例(这里会报错,不用管)
startup                      # 启动实例
