GitLab Mattermost をバックアップおよび復元して、ユーザー名とメッセージを保存できるようにしたいと思います。これまでのところ、メッセージは保存されていますが、ユーザー名がすべて「Someone」に置き換えられています。
私はレビューしましたMattermostのバックアップドキュメント:
私はPostgreSQLを使用しているので、PostgreSQL バックアップドキュメント。
バックアップには pg_dump、リストアには psql が推奨されていますが、これは私が構築した Zotonic サイトのバックアップとリストアを自動化していたことからよく知っているものです。
次のコマンドを実行する 1 時間ごとの cron があります:
sudo -i -u gitlab-psql -- /opt/gitlab/embedded/bin/pg_dump -h \
/var/opt/gitlab/postgresql mattermost_production |
gzip > "mattermost-backup.sql.gz"
私が服用するとmattermost-バックアップ.sql.gz次のように復元します。
gitlab-ctl stop mattermost
zcat mattermost-backup.sql.gz |
sudo -i -u gitlab-psql -- /opt/gitlab/embedded/bin/psql \
-h /var/opt/gitlab/postgresql \
-d mattermost_production
gitlab-ctl start mattermost
gitlab-psql はこれをログに記録します (多くの競合および制約エラーを含む)。

それが完了し、GitLab Mattermost が再び稼働すると、実際のユーザー名の代わりに「Someone」が表示されます。
ユーザー名を保持したまま GitLab Mattermost をバックアップおよび復元するにはどうすればよいですか?
答え1
復元先のレプリカ システムでは、次の操作を行う必要があります。
- MattermostでGitLabをインストールする（Omnibusインストールを使用）
- mattermost_productionデータベースを削除する
- 空のmattermost_productionデータベースを作成する
- バックアップSQLをロードする空のデータベース
当初のアプローチが失敗する理由は何でしょうか?
GitLab がインストールされると、Mattermost データベースにいくつかのレコードが入力されます。psql を実行してそれらのレコードの上にバックアップをロードすると、データベースに新規インストール データとバックアップ データの両方が含まれる不整合な状態になります。
これをどうやって修正しますか?
より確実にクリーンな復元を行うには、mattermost_production データベースを削除し、mattermost_production という新しい空のデータベースを作成してから、次のように psql を使用してバックアップ SQL を実行する必要があります。
gitlab-ctl stop mattermost
sudo -i -u gitlab-psql -- /opt/gitlab/embedded/bin/dropdb \
-h /var/opt/gitlab/postgresql \
mattermost_production
sudo -i -u gitlab-psql -- /opt/gitlab/embedded/bin/createdb \
-h /var/opt/gitlab/postgresql \
mattermost_production
zcat mattermost-backup.sql.gz |
sudo -i -u gitlab-psql -- /opt/gitlab/embedded/bin/psql \
-h /var/opt/gitlab/postgresql \
-d mattermost_production
gitlab-ctl start mattermost
