docker拉取oracle11g镜像并配置数据持久化

一、拉取oracle11g镜像

下载过程稍长，镜像大小6.8G（之前拉取过了，所以就不截图了）

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

镜像详情：https://dev.aliyun.com/detail.html?spm=5176.1972343.2.8.E6Cbr1&repoId=1969

下载完成后 查看镜像

# docker images

二、创建容器初步了解如何使用镜像

1、创建容器

# docker run -v /opt:/data -p 1521:1521 --name oracle11g -h demo --restart=always -d registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

说明

-v（映射主机目录到容器内，把opt目录映射到容器根目录data下）

--name（容器名）

--restart=always（设置容器开机自启动）

-d（创建容器之后不自动进入容器）

2、进入容器

# docker exec -it oracle11g bash

3、切换到root 用户下

$ su root

密码：helowin

4、编辑profile文件配置ORACLE环境变量

 # vi /etc/profile

在最后面添加如下内容

export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2           #oracle路径

export ORACLE_SID=helowin                                                    #oracle启动数据库实例名

export PATH=$ORACLE_HOME/bin:$PATH                                           #添加系统环境变量

5、立即生效

# source /etc/profile

6、创建软连接

ln -s $ORACLE_HOME/bin/sqlplus /usr/bin

7、切换到oracle 用户

这里还要说一下，一定要写中间的内条 -   必须要，否则软连接无效

 # su - oracle

8、登录oracle数据库

$ sqlplus /nolog

SQL> conn /as sysdba

9、修改sys、system密码

SQL> alter user system identified by system;

SQL> alter user sys identified by sys;

也可以创建用户  create user test identified by test;

并给用户赋予权限  grant connect,resource,dba to test;

修改oracle默认用户密码永不过期

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

SQL> exit

exit  是退休sql 软连接

10、查看监听是否成功启动

$ lsnrctl status

11、查看监听配置文件

注意：oracle监听文件不要随意更改，如若更改需要先备份一份

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

# 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 = 1521))


HELOWIN =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = helowin)
    )
  )

$ cd /home/oracle/app/oracle/product/11.2.0/dbhome_2/network/admin/

$ vi listener.ora

# 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 = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/oracle/app/oracle

连接oracle数据库时，先检查端口映射是否成功

打开Windows的doc窗口输入一下内容

telnet ip地址 端口号

三、制作属于自己定制的oracle11g镜像

两种方法

方法一：编写Dockerfile文件

方法二：容器打包成镜像

方法一：过程如下

有时间再写

方法二：过程如下

1、创建容器

# docker run --name oracle11g -d oracle_11g

[root@docker-servers ~]# docker run --name oracle11g -d oracle_11g
4826bc11291ebe022a159544d7ad233896723ede260b913c38d2fc101112b04f
[root@docker-servers ~]#
[root@docker-servers ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
4826bc11291e        oracle_11g          "/bin/sh -c '/home..."   44 seconds ago      Up 19 seconds       1521/tcp                 oracle11g

2、进入容器

# docker exec -it oracle11g bash

[root@docker-servers ~]# docker exec -it oracle11g bash
[oracle@4826bc11291e /]$
[oracle@4826bc11291e /]$

3、切换到root 用户下

root密码为：helowin

[oracle@4826bc11291e /]$ su root
Password:
[root@4826bc11291e /]#

4、编辑profile文件配置ORACLE环境变量

# vi /etc/profile

在最后面添加如下内容

export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

5、立即生效

# source /etc/profile

6、创建软连接

# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin

7、切换到oracle 用户

# su - oracle

8、登录oracle数据库

$ sqlplus / as sysdba

9、修改sys、system密码

SQL> alter user system identified by system;

SQL> alter user sys identified by sys;

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

[root@4826bc11291e /]# vi /etc/profile
[root@4826bc11291e /]# source /etc/profile
[root@4826bc11291e /]# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
[root@4826bc11291e /]#
[root@4826bc11291e /]# su - oracle
[oracle@4826bc11291e ~]$
[oracle@4826bc11291e ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Aug 14 18:09:43 2019

SQL>
SQL> alter user system identified by system;

User altered.

SQL> alter user sys identified by sys;

User altered.

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

Profile altered.

SQL>

10、退出容器打包成镜像

退出容器

# exit

根据某个“容器 ID”来创建一个新的“镜像”

# docker commit oracle11g oracle_11g:v1

[root@docker-servers ~]# docker commit oracle11g oracle_11g:v1
sha256:cbe72388da002ee16fa37a448221ec64f1bb5ab534d6904076f1276c3a7a4b72
[root@docker-servers ~]#
[root@docker-servers ~]# docker images
REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
oracle_11g                            v1                  cbe72388da00        6 seconds ago       6.86 GB
oracle_11g                            latest              3fa112fd3642        3 years ago         6.85 GB

可以看到，和之前的容器相比，镜像文件大了一点点

11、根据新镜像运行一个容器

# docker run -p 1523:1521 --name oracle11g_test -d oracle_11g:v1

[root@docker-servers ~]# docker run -p 1523:1521 --name oracle11g_test -d oracle_11g:v1
2963da8bbe11d451c727d27a501af647d4655106e62fe97b509fd6f7590e860a
[root@docker-servers ~]#
[root@docker-servers ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
2963da8bbe11        oracle_11g:v1       "/bin/sh -c '/home..."   31 seconds ago      Up 9 seconds        0.0.0.0:1523->1521/tcp   oracle11g_test

12、外部测试连接

先监听一下端口

# netstat -tunlp | grep 1523

[root@docker-servers ~]# netstat -tunlp | grep 1523
tcp        0      0 :::1523                 :::*                    LISTEN      23654/docker-proxy-

未能连接成功，实验失败

四、oracle容器数据持久化

具体方法说明：

如需映射oracle的数据文件 把容器内对应的文件，拷贝到宿主机，映射即可（如下）

/home/oracle/app/oracle/oradata/

/home/oracle/app/oracle/flash_recovery_area/helowin/

我映射的命令

# docker run -v /home/oracle11g-dev-pub/oradata:/home/oracle/app/oracle/oradata -v /home/oracle11g-dev-pub/flash_recovery_area/helowin/:/home/oracle/app/oracle/flash_recovery_area/helowin/ -p 1522:1521 --name oracle11g-dev -h dev -d oracle_11g

# docker run -v /opt/oracle11g-demo-pub/oradata:/home/oracle/app/oracle/oradata -v /opt/oracle11g-demo-pub/flash_recovery_area/helowin/:/home/oracle/app/oracle/flash_recovery_area/helowin/ -p 1521:1521 --name oracle11g-demo -h demo -d oracle_11g

具体操作如下：

1、先建一个测试容器

# docker run --name oracle11g_test -d oracle_11g

[root@localhost ~]# docker run --name oracle11g_test -d oracle_11g
0237fc1d788290398508749846bcce02640d17cfc588c460e2d46df31ebcf325

2、新建目录

# mkdir -p /opt/oracle11g-demo-pub/flash_recovery_area

# mkdir -p /opt/oracle11g-demo-pub/oradata

[root@localhost ~]# mkdir -p /opt/oracle11g-demo-pub/flash_recovery_area
[root@localhost ~]# mkdir -p /opt/oracle11g-demo-pub/oradata

3、拷贝数据

# docker cp oracle11g_test:/home/oracle/app/oracle/oradata/helowin /opt/oracle11g-demo-pub/oradata

# docker cp oracle11g_test:/home/oracle/app/oracle/flash_recovery_area/helowin/ /opt/oracle11g-demo-pub/flash_recovery_area

[root@localhost ~]# docker cp oracle11g_test:/home/oracle/app/oracle/oradata/helowin /opt/oracle11g-demo-pub/oradata
[root@localhost ~]# docker cp oracle11g_test:/home/oracle/app/oracle/flash_recovery_area/helowin/ /opt/oracle11g-demo-pub/flash_recovery_area

4、创建容器

# docker run -v /opt/oracle11g-demo-pub/oradata:/home/oracle/app/oracle/oradata -v /opt/oracle11g-demo-pub/flash_recovery_area/helowin/:/home/oracle/app/oracle/flash_recovery_area/helowin/ -p 1521:1521 --name oracle11g-demo_new -h demo -d oracle_11g

[root@localhost ~]# docker run -v /opt/oracle11g-demo-pub/oradata:/home/oracle/app/oracle/oradata -v /opt/oracle11g-demo-pub/flash_recovery_area/helowin/:/home/oracle/app/oracle/flash_recovery_area/helowin/ -p 1521:1521 --name oracle11g-demo -h demo -d oracle_11g
416f7073da96fb4a1bd1fc5bde05ba29007dce0ba68b717f50101527cc39f441
[root@localhost ~]#

查看容器

[root@localhost flash_recovery_area]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                    NAMES
416f7073da96        oracle_11g          "/bin/sh -c '/home..."   About a minute ago   Up 59 seconds       0.0.0.0:1521->1521/tcp   oracle11g-demo
0237fc1d7882        oracle_11g          "/bin/sh -c '/home..."   4 minutes ago        Up 4 minutes        1521/tcp                 oracle11g_test

5、进入容器root授权

# docker exec -it oracle11g-demo bash

[root@localhost flash_recovery_area]# docker exec -it oracle11g-demo bash
[oracle@demo /]$
[oracle@demo /]$ cd /home/oracle/app/oracle/flash_recovery_area/helowin/
bash: cd: /home/oracle/app/oracle/flash_recovery_area/helowin/: Permission denied

目录授权

$ su root

密码：helowin

[oracle@demo /]$ su root
Password:

drwxr-x--- 4 oracle oinstall 41 Jan  4  2016 HELOWIN
drwxr-x--- 2 oracle oinstall 52 Jan  4  2016 helowin

6、修改环境变量创建软连接

# vi /etc/profile

export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

# source /etc/profile

# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin

[root@demo oracle]# vi /etc/profile
[root@demo oracle]# source /etc/profile
[root@demo oracle]# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
[root@demo oracle]#

7、重启数据库

# su - oracle

$ sqlplus / as sysdba

SQL> shutdown immediate;

SQL> startup

[oracle@demo ~]$ sqlplus / as sysdba

 9、创建逻辑备份目录和普通用户存放的表空间的目录

$ cd /home/oracle/app/oracle/oradata

$ mkdir oracle_imp_exp

$ mkdir tablespace

SQL> exit

drwxr-xr-x 2 oracle oinstall   6 Aug 15 19:12 tablespace

10、外部就可以测试连接了

已经成功连接上数据库

五、持久化数据异机迁移

1、关闭容器数据打包

# docker stop oracle11g-demo

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
416f7073da96        oracle_11g          "/bin/sh -c '/home..."   32 minutes ago      Up 32 minutes       0.0.0.0:1521->1521/tcp   oracle11g-demo
0237fc1d7882        oracle_11g          "/bin/sh -c '/home..."   36 minutes ago      Up 36 minutes       1521/tcp                 oracle11g_test
[root@localhost ~]#
[root@localhost ~]# docker stop oracle11g-demo
oracle11g-demo
[root@localhost ~]#

数据打包

# tar zcvf oracle11g-demo-pub.tar.gz oracle11g-demo-pub/

[root@localhost ~]# cd /opt/
[root@localhost opt]#
[root@localhost opt]# ls
oracle11g-demo-pub
[root@localhost opt]#
[root@localhost opt]# tar zcvf oracle11g-demo-pub.tar.gz oracle11g-demo-pub/

2、迁移数据到别的Linux机器且具有docker环境

[root@localhost opt]# ls
ip.sh  oracle11g-demo-pub  oracle11g-demo-pub.tar.gz
[root@localhost opt]#
[root@localhost opt]# du -sh oracle11g-demo-pub.tar.gz
276M    oracle11g-demo-pub.tar.gz
[root@localhost opt]#
[root@localhost opt]# du -sh oracle11g-demo-pub
1.6G    oracle11g-demo-pub

# scp oracle11g-demo-pub.tar.gz root@192.168.2.207:/opt/

[root@localhost opt]# scp oracle11g-demo-pub.tar.gz root@192.168.2.207:/opt/

[root@localhost opt]#

3、另一台机器数据解压

# tar zxvf oracle11g-demo-pub.tar.gz

[root@docker-servers ~]# cd /opt/
[root@docker-servers opt]#
[root@docker-servers opt]# ls
oracle11g-demo-pub.tar.gz
[root@docker-servers opt]#
[root@docker-servers opt]# tar zxvf oracle11g-demo-pub.tar.gz

解压后

[root@docker-servers opt]# ls
oracle11g-demo-pub  oracle11g-demo-pub.tar.gz
[root@docker-servers opt]#
[root@docker-servers opt]# du -sh oracle11g-demo-pub
1.6G    oracle11g-demo-pub
[root@docker-servers opt]#
[root@docker-servers opt]# du -sh oracle11g-demo-pub.tar.gz
276M    oracle11g-demo-pub.tar.gz
[root@docker-servers opt]#

4、创建容器

# docker run -v /opt/oracle11g-demo-pub/oradata:/home/oracle/app/oracle/oradata -v /opt/oracle11g-demo-pub/flash_recovery_area/helowin/:/home/oracle/app/oracle/flash_recovery_area/helowin/ -p 1521:1521 --name oracle11g-demo_new -h demo -d oracle_11g

5、重启数据库

# docker exec -it oracle11g-demo bash

$ su root

# su - oracle

$ sqlplus / as sysdba

SQL> shutdown immediate;

SQL> startup

[root@localhost opt]# docker exec -it oracle11g-demo bash
[oracle@demo /]$
[oracle@demo /]$ su root
Password:
[root@demo /]#
[root@demo /]# su - oracle
[oracle@demo ~]$
[oracle@demo ~]$ sqlplus / as sysdba
