当我开始
上限生产部署
cap production deploy
它像这样失败:
DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/releases/20131025212110 && (RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/myapp_rake assets:precompile ) DEBUG [4ee8fa7a] rake aborted! DEBUG [4ee8fa7a] database configuration does not specify adapter您可以看到 RAILS_ENV = 实际上是空的,我想知道为什么会这样吗?我认为这是我没有数据库配置的后一个错误的原因。 deploy.rb文件如下:
You can see that "RAILS_ENV=" is actually empty and I'm wondering why that might be happening? I assume that this is the reason for the latter error that I don't have a database configuration. The deploy.rb file is below:
set :application, 'myapp' set :repo_url, 'git@github:developer/myapp.git' set :branch, :master set :deploy_to, '/home/deploy/myapp/releases' set :scm, :git set :devpath, "/home/deploy/myapp_development" set :user, "deploy" set :use_sudo, false set :default_env, { rvm_bin_path: '~/.rvm/bin' } set :keep_releases, 5 namespace :deploy do desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do # Your restart mechanism here, for example: within release_path do execute " bundle exec thin restart -O -C config/thin/production.yml" end end end after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do within release_path do end end end after :finishing, 'deploy:cleanup' endDatabase.yml:
Database.yml:
production: adapter: mysql2 encoding: utf8 database: myapp_production pool: 5 username: user password: pass host: localhost development: adapter: mysql2 encoding: utf8 database: myapp_development pool: 5 username: user password: pass host: localhost如果我添加
set :rails_env, "production"到我的deploy.rb,但这对我来说似乎是硬编码,我敢肯定有更好的解决方案。 / p>
to my deploy.rb, but this looks like hardcoding to me and I'm sure there's a nicer solution.
推荐答案编辑:每此提取请求,现已在 capistrano-rails 的 1.1.0 版本中修复
Per this pull request, it's now fixed in version 1.1.0 of capistrano-rails.
每个此Github问题,另一个解决方法是编辑您的 Capfile 。注释掉这两行
Per this Github issue, another fix is to edit your Capfile. Comment out these two lines
#require 'capistrano/rails/assets' #require 'capistrano/rails/migrations'并将此行放入
require 'capistrano/rails'这将正确设置 RAILS_ENV 变量。
