1 2 $ cat /etc/issue Ubuntu 14.04.4 LTS
It was using gitlab-rake to backup and restore the gitlab repository in this tutorial
First of all, you must check the gitlab version in old server!!
1 2 $ cat /opt/gitlab/embedded/service/gitlab-rails/VERSION 8.7.0
The old gitlab server version is 8.7.0.
So the new machine gitlab version must be 8.7.0, because the data backup by gitlab tool named ‘gitlab-rake’ which can only be recovery in same version.
It was worked for me as well.
1 $ sudo apt-get install -y curl openssh-server ca-certificates postfix Install gitlab-ce in new machine
In china, it may be slowly to download, so you can use another apt resource image. Of course you can pass this step with a fast network.
1 $ sudo sh -c "echo 'deb https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/debian jessie main' >> /etc/apt/sources.list.d/gitlab-ce.list"
then search gitlab 8.7.0 version
1 2 3 $ sudo apt-cache policy gitlab-ce | grep 8.7.0 Installed: 8.7.0-ce.0 *** 8.7.0-ce.0 0
1 $ sudo apt-get install gitlab-ce=8.7.0-ce.0 Backup gitlab repository as a tar package in old server
1 $ gitlab-rake gitlab:backup:create RAILS_ENV=production
In general, backup files are usually stored in directory ‘/var/opt/gitlab/backups’, check the tar file named ‘1490248589_gitlab_backup.tar’. The number 1490248589 was timestamp.
Distinguish different backup version.
1 $ scp /var/opt/gitlab/backups/1490248589_gitlab_backup.tar username@new-server:/var/opt/gitlab/backups/
Copy the gitlab repository backup file to new server
Restore repositofy in new server
1 $ gitlab-rake gitlab:backup:restore RAILS_ENV=production BACKUP=1490248589 If something went wrong
/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.8’ not found (required by …
1 2 3 $ sudo add-apt-repository ppa:ubuntu-toolchain-r/test $ sudo apt-get update $ sudo apt-get install g++-4.9
Or you can install by apt-fast when apt install g++ as a snails
1 $ sudo apt-fast install gcc-4.9 g++-4.9
Repositories backup successfully but getting a 500 page after click the project name in the web view, and gitlab error log shows that
1 gitlab ErrorPage: serving predefined error page: 500
It caused by the gitlab security file ‘/etc/gitlab/gitlab-secrets.json’, you should copy this file in old server to new server at this time
