乘客5 / Capistrano

Question

我正在嘗試通過Capistrano將Rails應用程序部署到VPS。 我在VPS上安裝了乘客獨立，並使用默認配置的capistrano-passenger gem。

運行cap deploy會產生以下輸出：

DEBUG [3197887c] Finished in 0.046 seconds with exit status 0 (successful).

DEBUG [8557b41e]        PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir
DEBUG [8557b41e]        

我正在使用默認配置。 我能做些什么才能讓它發揮作用？

Answer 1

使用set :passenger_restart_with_touch, true作為Passenger 5的變通方法。

這是https://github.com/capistrano/passenger/issues/26中描述的已知問題

Answer 2

我最近碰到了這個，我的情況是因為deploy用戶需要對passenger-config命令使用sudoer權限。

Answer 3

你的Gemfile中有寶石'乘客'嗎？ 確保您的VPS上安裝了乘客寶石。 此外，如果您需要Nginx作為Web服務器，請在您的VPS rvmsudo passenger-install-nginx-module上運行以下命令。 如果您需要進一步的幫助，請告訴我。

Answer 4

首先，您應確保乘客當前正在您的服務器上運行，因此請嘗試： rvmsudo bundle exec passenger start 。 如果這樣可行，請嘗試設置：

set :passenger_in_gemfile, true
set :passenger_restart_with_sudo, true

然后檢查cap production passenger:restart的設置cap production passenger:restart 。
（適用於通過Gemfile安裝的Passenger Standalone ）。
