Gitlab源码迁移

参考官方文档：https://gitlab.com/gitlab-org/gitlab-foss/blob/master/doc/raketasks/import.md

1. 先创建等待导入的分组，比如bank

sudo -u git mkdir -p /var/opt/gitlab/git-data/repository-import/bank

2 这步把所有老bank源码.git拷贝到新建分组目录bank下等待导入

sudo cp -r /old/bank/* /var/opt/gitlab/git-data/repository-import/bank/

3. 设置权限 Do this once when you are done copying git repositories

sudo chown -R git:git /var/opt/gitlab/git-data/repository-import

4.执行导入

sudo gitlab-rake gitlab:import:repos['/var/opt/gitlab/git-data/repository-import']

这一步执行后，就会把/var/opt/gitlab/git-data/repository-import/bank 写入到 /var/opt/gitlab/git-data/repositories/bank下了，导入完成。
