There is too much information in each of the local/k8s/dev docs pages. The "guides" that are listed in each one of those pages are moved either to "common tasks" or to a dedicated "tutorials" section. This paves the way for more comprehensive tutorials, where we describe how to run the latest master branches of Open edX. I am well aware that, as they stand, the tutorials are of poor quality and should be rewritten. This is a task for another day/commit. For now, we only move the contents to a separate part of the docs. Also, we should add a "reference" section to the docs, where we add the result of `tutor <subcommand> --help`.

Making backups and migrating data
|
|
---------------------------------
|
|
|
|
With Tutor, all data are stored in a single folder. This means that it's extremely easy to migrate an existing platform to a different server. For instance, it's possible to configure a platform locally on a laptop, and then move this platform to a production server.
|
|
|
|
1. Make sure `tutor` is installed on both servers with the same version.
|
|
2. Stop any running platform on server 1::
|
|
|
|
tutor local stop
|
|
|
|
3. Transfer the configuration, environment and platform data from server 1 to server 2::
|
|
|
|
rsync -avr "$(tutor config printroot)/" username@server2:/tmp/tutor/
|
|
|
|
4. On server 2, move the data to the right location::
|
|
|
|
mv /tmp/tutor "$(tutor config printroot)"
|
|
|
|
5. Start the instance with::
|
|
|
|
tutor local start -d
|
|
|
|
Making database dumps
|
|
---------------------
|
|
|
|
To dump all data from the MySQL and Mongodb databases used on the platform, run the following commands::
|
|
|
|
tutor local exec -e MYSQL_ROOT_PASSWORD="$(tutor config printvalue MYSQL_ROOT_PASSWORD)" mysql \
|
|
sh -c 'mysqldump --all-databases --password=$MYSQL_ROOT_PASSWORD > /var/lib/mysql/dump.sql'
|
|
tutor local exec mongodb mongodump --out=/data/db/dump.mongodb
|
|
|
|
The ``dump.sql`` and ``dump.mongodb`` files will be located in ``$(tutor config printroot)/data/mysql`` and ``$(tutor config printroot)/data/mongodb``.
