# Importing a database dump into a staging environment
|
|
|
|
Sometimes it is useful to import the database from a production environment
|
|
into a staging environment for testing. The procedure below assumes you have
|
|
SSH and `sudo` access to both the production environment and the staging VM.
|
|
|
|
**Destroy your staging VM** when you are done with it. It is important to avoid
|
|
data leaks.
|
|
|
|
On the staging VM, add the following line to `/etc/gitlab/gitlab.rb` to speed up
|
|
large database imports.
|
|
|
|
```shell
|
|
# On STAGING
|
|
echo "postgresql['checkpoint_segments'] = 64" | sudo tee -a /etc/gitlab/gitlab.rb
|
|
sudo touch /etc/gitlab/skip-auto-reconfigure
|
|
sudo gitlab-ctl reconfigure
|
|
sudo gitlab-ctl stop unicorn
|
|
sudo gitlab-ctl stop sidekiq
|
|
```
|
|
|
|
Next, we let the production environment stream a compressed SQL dump to our
|
|
local machine via SSH, and redirect this stream to a `psql` client on the staging
|
|
VM.
|
|
|
|
```shell
|
|
# On LOCAL MACHINE
|
|
ssh -C gitlab.example.com sudo -u gitlab-psql /opt/gitlab/embedded/bin/pg_dump -Cc gitlabhq_production |\
|
|
ssh -C staging-vm sudo -u gitlab-psql /opt/gitlab/embedded/bin/psql -d template1
|
|
```
|
|
|
|
## Recreating directory structure
|
|
|
|
If you need to re-create some directory structure on the staging server you can
|
|
use this procedure.
|
|
|
|
First, on the production server, create a list of directories you want to
|
|
re-create.
|
|
|
|
```shell
|
|
# On PRODUCTION
|
|
(umask 077; sudo find /var/opt/gitlab/git-data/repositories -maxdepth 1 -type d -print0 > directories.txt)
|
|
```
|
|
|
|
Copy `directories.txt` to the staging server and create the directories there.
|
|
|
|
```shell
|
|
# On STAGING
|
|
sudo -u git xargs -0 mkdir -p < directories.txt
|
|
```
