錯誤將GitLab 6.1升級到6.3

Question

我想更新Gitlab（6.1到6.3），但在Checkout之後會發生這種情況。

我更新的命令數據庫：

ruby bin/rake db:migrate RAILS_ENV=production 

我需要知道如何解決：

Can't connect to local MySQL server through socket '/home/gitlab/mysql/tmp/mysql.sock' (2) 

SYSTEMINFO：

• 的Ubuntu 12.10 64
• LTS紅寶石2.0，
• GitLab 6.1

完整的輸出：

Answer 1

您可以檢查 「Can't connect to local MySQL server through socket '/path/to/mysql.sock'」 背後的錯誤消息的各種常見原因。

該路徑配置在您的gitlab/config/database.yml.mysql文件中。

主要是：

• 檢查你的MySQL正在運行（中mysqladmin -u根-p狀態）
• 檢查的訪問權限（sudo chmod -R 755 /home/gitlab/mysql/tmp/mysql）
• 檢查/etc/mysql/my.cnf
• 檢查how/if you have installed mysql-server。

另外，還要確保你跟隨migration process：

sudo -u git -H bundle install --without development test postgres --deployment 
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
