数据库变更

后端数据库表结构变更共耗时3个半小时，前端xxx
sudo -u git -H bundle exec rake gitlab:sidekiq:check --trace RAILS_ENV=production
sudo -u git -H RAILS_ENV=production bin/background_jobs start
sudo -u git -H RAILS_ENV=production bin/background_jobs killall
升级最好提前把share/artifacts/下项目ci构建的数据拷贝到迁移机器上，不然会在计划任务重建，把sidekiq撑爆，影响打包
已计划
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/18615
fatal: destination path '/builds/i18n-server/mi-event' already exists and is not an empty directory.
pipelines点击clear runner caches清除缓存
升级后sidekiq很容易删掉，提示是有bug，需要重装re2

或者考虑降级

ci使用git submodule编译报错：
.gitlab-ci.yml去掉以下配置：
before_script:
- git submodule sync --recursive
- git submodule update --init --recursive
（gitlab-runner >1.10+）建议改为：
variables:
GIT_SUBMODULE_STRATEGY: recursive
https://docs.gitlab.com/ee/ci/git_submodules.html
部分项目merge一直转，也关闭不了，只能新fork，merge报500错误，将mysql 5.5数据库升级成5.7可解决，
也可以提升下机器配置，merge会更快。

ci报错，提示/builds/xxx已存在或不为空
解决：
Go to project Settings->CI/CD->General pipelines settings:
Change Git strategy for pipelines from
git fetch
to
git clone
Retry Build
