Analyze the problem of pulling down the Oracle 11g image configuration in Docker

1. Pull the image

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

Image details: https://dev.aliyun.com/detail.html?spm=5176.1972343.2.8.E6Cbr1&repoId=1969

Since I have already pulled the image, it is shown here as existing. Check the image information

docker images

2. Create and container information

docker run -d -p 1521:1521 --name oracle_11g registry.aliyuncs.com/helowin/oracle_11g

Since my container has been created here (the command is as expected, the container name is oracle_11g), I can start it directly here.

docker start oracle_11g

3. Enter the console to set user information

docker exec -it oracle_11g bash

Log in to sqlplus. It is found that the sqlplus command is not available here, so relevant configuration is required. The steps are as follows:

(1) Switch to root user mode

su root

Enter the password helowin

(2) Edit the profile file to configure the ORACLE environment variables

vi /etc/profile and add the following command at the end of the file

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

export ORACLE_SID=helowin

export PATH=$ORACLE_HOME/bin:$PATH

Exit and save.

(3) Software connection

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

Because I have already created it, the package flag already exists.

(4) Switch to oracle user

Log in to sqlplus and modify the passwords of sys and system users

sqlplus /nolog

conn /as sysdba

Then execute the following command

alter user system identified by oracle;

alter user sys identified by oracle;

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

4. Login verification

Login successful

5. Submit changes

docker commit container name or ID new image name: version
