Docker installs Oracle11g (simple installation)

background

It is very troublesome to install oracle in Linux, and I believe everyone will encounter various pits. In order to install it once, it is also convenient to directly export the image for transplantation on various platforms in the future, so I choose to install Oracle with docker.

The download speed is very slow using the official image, so we can use the Ali image.

pull image

1. Pull the oracle_11g image

Pull the oracle image (oracle 11.0.2 64bit enterprise version instance name: helowin)

Oracle is mainly installed on the basis of Docker. Pay attention to space and memory in the installation environment. Oracle is a very large piece of software.

The minimum configuration should be more than 2G, and the hard disk should be more than 30G, because the image has a size of 6.8G.

Log in to the Alibaba container image service platform, find the image center --> image search, enter the corresponding image name to find a suitable image.

It is recommended to use Netease mirror or Ali mirror website here to oracle 11.0.2 64bit enterprise version

Instance name: helowin is an example for installation details.

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

2. run container

2.1 The default way to start the container

docker run -d --name oracle11g -p 1521:1521 --restart=always registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g 

或
docker run -d -it -p 1521:1521 \
--name oracle11g \
--restart=always registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g 

2.2 The way of persistent startup

docker run -d -it -p 1521:1521 --name oracle11g --restart=always --mount source=oracle_vol,target=/home/oracle/app/oracle/oradata registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

或
docker run -d -it -p 1521:1521 \
--name oracle11g \
--restart=always \
--mount source=oracle_vol,target=/home/oracle/app/oracle/oradata registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

Generally, the default startup method is enough. If the data needs to be saved locally, the persistent method is used.

--mount means to mount the path on the Host into the container.

source=oracle_vol is the persistent volume of the Host. If it is not created in advance, it will be created automatically. You can pass

target=/home/oracle/app/oracle/oradata: your own Linux home directory

docker volume inspect oracle_vol

View the specific location of the volume, target is the path in the container

3. View container startup status

docker ps | grep oracle11g  

4. Enter the oracle11g container for configuration

docker exec -it oracle11g /bin/bash 

5. Switch to the root user for configuration:

Switch root user: su root

Enter password: helowin ##You can use the passwd command to change your own password

6. Edit the profile file to configure the ORACLE environment variable:

vi /etc/profile  

At the end of the document, add the following:

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

7. After saving, load the environment variable and it will take effect immediately:

source /etc/profile  

8. Create a soft link:

Function: You can use the oracle command directly without entering the bin directory to execute the corresponding command.

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

9. Switch to the oracle user:

su - oracle  

登录sqlplus并修改sys、system用户密码:
sqlplus /nolog                                      # 登录oracle
conn /as sysdba                                     # 连接,需要进行操作系统验证，才可进行连接登录
alter user system identified by system;                        # 修改system用户账号密码system
alter user sys identified by sys;                              # 修改sys用户账号密码sys
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;      # 修改密码规则策略为密码永不过期
exit;                                                          # 退出

10. supplementary order

补充命令
登录sqlplus并修改sys、system用户密码: 需要注意的是再oracle用户下操作
sqlplus /nolog                                      # 登录
conn /as sysdba                                     # 连接
create user test identified by test;                #创建内部管理员账号密码；
grant connect,resource,dba to yan_test;             #将dba权限授权给内部管理员账号和密码；
alter system set processes=1000 scope=spfile;       #修改数据库最大连接数据；
修改以上信息后，需要重新启动数据库
shutdown immediate;                                 #关闭数据库
startup;                                            #启动数据库
SQL> select instance from v$thread;                 #查看数据库sid(实例名)
clear SCR  或clear screen或clea scre                 #sqlplus清屏命令
创建表空间
create tablespace pts datafile '/home/oracle/app/oracle/oradata/helowin/pts.dbf' size 100m autoextend on next 10m

删除表空间
drop tablespace PTS;

查看所有表空间
select tablespace_name from dba_tablespaces;

创建用户
create user PTS identified by PTS default tablespace PTS;

删除用户
drop user pts cascade;

为sys用户添加sysdba权限
SQL> grant sysdba to sys;

查看哪些用户被授予DBA权限
select * from dba_role_privs where granted_role='DBA';

查看数据库编码
SQL> select userenv('language') from dual;

View database permissions and users

SQL> show parameter password         #查看数据库权限
SQL> select * from v$pwfile_users;   #查看用户

11. Check the oracle instance status:

lsnrctl status             -查看一下oracle实例状态:

listen command

$ lsnrctl stop listener    -停止名为listener的监听服务
$ lsnrctl start listener   -启动名为listener的监听服务
$ lsnrctl reload listener  -重新加载名为listener的监听服务

View environment variables

cat /home/oracle/.bash_profile

看到此ORACLE_SID=helowin表示数据库的实例名称
