在 gitlab 综合安装上创建备份时出现权限错误

我正在使用 gitlab 版本 7.10.4，我正在尝试升级安装。但是当我尝试创建备份时我得到了这个

gitlab-rake gitlab:backup:create

请帮我解决这个问题。

首先，gitlab 文档似乎认为你应该使用 sudo 运行该命令：

https://github.com/gitlabhq/gitlabhq/blob/7-10-stable/doc/raketasks/backup_restore.md

基于代码：

https://github.com/gitlabhq/gitlabhq/blob/7-10-stable/lib/backup/manager.rb

看起来它正在配置的备份目录 (Gitlab.config.backup.path) 中的 3 个目录（存储库、数据库、上传）上运行 chmod 700（并且在数据库上失败）。根据文档，该 Gitlab.config.backup.path 变量是从 config/gitlab.yml 中提取的。如果找不到该配置文件，可以临时在 /opt/gitlab/embedded/service/gitlab-rails/lib/backup/manager.rb:19 上面添加一行来打印备份目录：

puts("Backup dir is: #{Gitlab.config.backup.path}")

您也许还可以使用 strace 命令获取相同的信息：

$ strace -f gitlab-rake gitlab:backup:create 2>&1 | grep "^chdir\|^fchdir"

找到备份目录后，查看其中的 db 目录。应应用标准 Linux 权限故障排除。您以什么用户身份运行该命令以及该目录具有什么权限集？根据需要 Sudo chmod/chown。
