Fails to initialize MySQL database on Windows 10

Question

Using Laradock

System Info:

• Docker version: 17.10.0-ce, build f4ffd25
• OS: Windows 10 Home

When I run docker-compose up -d mysql I'm getting error. Following is the docker logs

[Note] Basedir set to /usr/

[Warning] The syntax '--symbolic-links/-s' is deprecated and will be removed in a future release

[Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.

[ERROR] --initialize specified but the data directory has files in it. Aborting.

[ERROR] Aborting

I have tried deleting mysql folder under ~/.laradock\data and didn't work.

Update 1

MySQL Container under laradock Dockerfile

mysql:
  build:
    context: ./mysql
    args:
      - MYSQL_VERSION=${MYSQL_VERSION}
  environment:
    - MYSQL_DATABASE=${MYSQL_DATABASE}
    - MYSQL_USER=${MYSQL_USER}
    - MYSQL_PASSWORD=${MYSQL_PASSWORD}
    - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
    - TZ=${WORKSPACE_TIMEZONE}
  volumes:
    - ${DATA_SAVE_PATH}/mysql:/var/lib/mysql
    - ${MYSQL_ENTRYPOINT_INITDB}:/docker-entrypoint-initdb.d
  ports:
    - "${MYSQL_PORT}:3306"
  networks:
    - backend

MySQL Dockerfile

After I delete mysql folder under ~/.laradock/data I'm getting following error. After the command it generates the files in below image. When I rerun giving back the previous error mentioned above.

** I tried in a windows 7 machine and its working.

Answer 1

I had the same problem with my Windows 10 Enterprise, I couldn't find perfect solution around it because it seems to be my Windows version issue - I have ran the same image on other windows (8 & 10 professional) successfully. My temporary work around was to remove the /var/lib/mysql mount entirely from the docker-compose file allowing the database data files to be created and modified in the container itself.

I use kitematics which will restart and reattach my created container anytime I want to work on the container, like that I don't loose my data when the container exit. If you don't use kitematics this what it does. After running docker-compose the image will be created and a container will be created to run it as well, I avoid using run on the created image because this will create new container I stick to running the following sequentially

docker ps -a                 # this command will get container_id of all container, those that are running and those that are not
docker start <container_id>  # start container from background
docker attach <container_id> # attach container to standard input

With these docker commands my data were preserved in the container even after exiting and restarting

BACK UP

Now whenever I want to move the data, I will commit my container into an image and save the image to local storage

docker commit <container_id> <backup_image_name>:<1_31_2017> # I use date to tag it
docker save -o <local_storage_tar_name> <backup_image_name>

RESTORE

Whenever I need to restore the mysql container either on my computer or for a new programming intern

cd <dir_containing_the_tar_file>
docker load -o <local_storage_tar_name> 

This solution is for your update

 File ./ib_logfile101: 'aio write' returned OS error 122. Cannot continue operation

I hope this helps somebody

Answer 2

Disable AIO

This fixed it for me when I got the AIO error as you did when I was starting a container from a guest Debian OS from Virtualbox and creating the database files on a shared folder on Windows 10.

The issue seems to be that AIO is not supported on shared folders, or at least on some versions of Windows. It seems to have occurred for me after I moved from Windows 10 Pro to Home after my main machine crashed.

For details:

• aio
• disable aio in MySQL for zfs

Here are some options:

Option 1 - start the container like this :

docker run -it mysql --innodb_use_native_aio=0

Option 2 - add the command to your docker-compose file:

 command: --innodb_use_native_aio=0

In context, this is the relevant portion of my working docker-compose.yml:

services:
   db:
     image: ${MYSQL_IMAGE}
     command: "--innodb_use_native_aio=0"
     volumes:
       - ${DB_DATA_PATH}:/var/lib/mysql
     ports:
        - ${MYSQL_PORT}:3306

Option 3 -- add an option to your my.cnf file in your build

innodb_use_native_aio=0

Option 4 - Don't persist your DB on the local file system.(Can destroy your db, Not Recommended)

Simply remove the volume in your docker configuration that contains your mysql db. Of course, your DB will be deleted if you do a docker-compose down or otherwise destroy your container, so there's that.

Answer 3

I am not sure but Try this step.This is because of data folder.

Try remove the docker image. List all images using docker images then remove the mysql & laradock mysql using docker rmi imagename. Dont forget remove the docker volume using docker volume rm volumename Also go to cd ~/.laradock/data remove the mysql folder.

Then try docker-compose up mysql for debuging. If no errors, you could try docker-compose up -d mysql
