我正在尝试将我的rails应用程序部署到Amazon Ec2。
我正在使用Capistrano + Unicorn + Nginx。
deploy:setup工作正常,但是当我尝试部署:cold时,出现错误:
servers: ["ec2-xx-xxx-xx-xx.sa-east-1.compute.amazonaws.com"]
[ec2-xx-xxx-xx-xx.sa-east-1.compute.amazonaws.com] executing command

我在StackOverFlow中搜索过,我看到一些主题可以帮助我,但没有成功。

最后我解决了我的问题。这个链接帮我解决了!

我只是改变了unicorn_init.sh的路径。谢谢大家。

erro su: must be run from a terminal
来自你的unicorn_init.sh。
在run()函数中,需要在'deployer'用户会话中调用它。
请专注于此,似乎代码与您收到错误的内容不同。
e.g。
你提到了
failed: "rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '2.1.0' -c '/etc/init.d/unicorn_app start'" on ec2-xx-xxx-xx-xx.sa-east-1.compute.amazonaws.com
但是在你的capistrano配置中,它说应用程序是'myapp'。
set :application, "myapp"
# ...
%w[start stop restart].each do |command|
desc "#{command} unicorn server"
task command, roles: :app, except: {no_release: true} do
# this will make command '/etc/init.d/unicorn_myapp start|stop|restart'
run "/etc/init.d/unicorn_#{application} #{command}"
end
end
通过ssh
set :user, "deployer"
)用户登录
确保您可以运行bellow命令启动独角兽。
rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '2.1.0' -c '/etc/init.d/unicorn_myapp start'
