Gitlab的話我目前是從6.1打算升級到6.2來著的，前麵的都按照升級教程比較完美的進行了。除了在第五步需要rake幾個命令的時候提示了rake aborted!出錯信息如下：
root@ubuntu-gitlab:/home/git/gitlab# sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

root@ubuntu-gitlab:/home/git/gitlab#
其它步驟都是正常的。然後到了第8步的時候啟動Gitlab就出現了如下錯誤：
root@ubuntu-gitlab:/home/git/gitlab# sudo service gitlab start
Removing stale Unicorn web server pid. This is most likely caused by the web server crashing the last time it ran.
Removing stale Sidekiq web server pid. This is most likely caused by the Sidekiq crashing the last time it ran.
Starting the GitLab Unicorn web server...
master failed to start, check stderr log for details
Starting the GitLab Sidekiq event dispatcher...
The GitLab Unicorn webserver is not running.
The GitLab Sidekiq job dispatcher with pid 4030 is running.
我搜了一下有嚐試用pkill將進程殺掉，不過好像都不太管用的樣子，不知道是不是我的方法沒用對的原因。之前從5.4升級到6.0的時候也碰上過同樣的錯誤，然後有看到Gitlab 的Github issue 上有人吐槽這個問題，沒過兩天我再重新按照教程步驟來就已經正常了。不過這回都到6.4了，也沒看見人吐槽這個問題，所以想應該不是程序問題是我這邊的問題吧。
另外因為升級失敗，本來想暫時退回到6.1去的結果也同樣出現了這個報錯，之前從5.4升級到6.0的時候我是按照教程順利退回到5.4了的。
另外，這是目前的LOG日誌文件：http://imnerd.org/lab/unicorn.stderr.log
情況就是以上這些，還請各位懂的答疑解惑，謝謝！

請檢查下你的config文件夹下的相关配置是否正确，特别是database.yml。感觉是，数据库的配置有问题，导致migration無法執行。
不知道，升級前運行gitlab是在生產環境（RAILS_ENV=production）还是在开发环境（RAILS_ENV=development）。如果是开发环境，那么事实上应该运行sudo -u git -H bundle exec rake db:migrate RAILS_ENV=development。
或者，嘗試讓開發環境和生產環境使用相同的資料庫配置（好吧，其實這不是最佳實踐）：
development: &local
adapter: mysql2
encoding: utf8
database: db_name
pool: 5
username: root
socket: /tmp/mysql.sock
test:
<<: *local
database: db_name_test
production:
<<: *local
