起因
由于服务器到期需要迁移git服务器到另外的一台上。
方案
使用官方迁移方案解决（一个很深的坑，网上有写方案是只是用低版本的，大家最好去官方获取最新的迁移方式。）
步骤（我用的是docker）
迁移文档在gitlab地址https://..**/help/raketasks/backup_restore.md
1. 备份
docker exec -t <container name> gitlab-backup create

Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data
and are not included in this backup. You will need these files to restore a backup.
Please back them up manually.
Backup task is done.
导出备份会存储在/home/gitlab/data/backups目录下
将文件拷贝到新的服务器上/home/gitlab/data/backups目录下
修改权限
chmod 755 1602316095_2020_10_10_13.2.6_gitlab_backup.tar
# Stop the processes that are connected to the database
docker exec -it <name of container> gitlab-ctl stop unicorn
docker exec -it <name of container> gitlab-ctl stop puma
docker exec -it <name of container> gitlab-ctl stop sidekiq
# Verify that the processes are all down before continuing
docker exec -it <name of container> gitlab-ctl status
# Run the restore
docker exec -it <name of container> gitlab-backup restore BACKUP=1602316095_2020_10_10_13.2.6
# Restart the GitLab container
docker restart <name of container>
# Check GitLab
docker exec -it <name of container> gitlab-rake gitlab:check SANITIZE=true
然后静静等待就可以了。我在10月10日的时候有用就的方式恢复是可以的。但是不知道为什么，15日正式操作的时候一直报异常，折腾了几个小时候后用官方的终于恢复成功了。
