cap部署:未配置冷生产数据库- Postgresql
提问于 2013-01-03 21:28:36
我试着用postgresql来安装一个rails应用，但是我不明白什么是‘生产数据库没有配置’或者其他任何东西。

该错误消息意味着您没有在database.yml中配置生产数据库。
查看远程服务器上的database.yml。
它看起来应该类似于：
production:
adapter: mysql2
encoding: utf8
reconnect: false
database: database_name
pool: 5
username: database_user
password: th3p4ssw0rd
socket: /path/to/mysql.sock我建议做以下几点：
1.)不要在版本控制下存储您的database.yml。使用git时，只需在.gitignore文件中添加/config/database.yml (或创建该文件)并提交即可。
2.)在shared/config/中的远程服务器上创建database.yml (通过脚本或手动)。
3.)在部署时，将应用程序中的database.yml符号链接到shared/config。
# /config/deploy.rb:
after 'deploy:finalize_update', 'db:symlink'
namespace :db do
desc "Symlinks the database.yml"
task :symlink, :except => { :no_release => true }, :roles => :app do
run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
