部署Rails应用

Question

I have been asked to make a few cosmetic changes to our production deployment. I have access to our linux box where I can see the files I need to change. I only need to change html.erb files, but when I add, for instance a simple <p> tag, it does not show up live.

I know I probably have to reset the server or redeploy the code, but I have no idea what to do.

Our production deployment is not fully live, so I am making changes on the fly (I know that this is not the best practice). Our app is running in a shared hosting environment for the moment.

I have seen threads where people use Capistrano to deploy but how? We do not currently use it.

Can anyone help?

Answer 1

Whenever you make changes in production files, you have to restart the server to see the changes. In production environment cache_classes is set to true. One can disable it and changes will be reflected without restarting the server. So to reflect the change restart the server.

thanks......

I found a good guide on the Capistrano github wiki and also used this guide @ kris.me.uk about a complete rails setup, including the Capistrano deployment aspect. I used them when learning how to deploy rails apps effectively. They should tell you what you need to know to get a basic deployment setup up and running.

Answer 3

I wrote a Capistrano // NGINX guide and posted it on my blog. It's 85% correct, and should help you understand the big picture of the server/Rails/SSH configurations.

Answer 4

Just incase someone is looking for the answer:

When rails is in development mode it will automatically reload changed files. When in production I need to restart it.

I eventually found out that we use God (A proces monitoring framework for rails - link here ).

I had to restart our app with the following command: 'god restart APP_NAME'

Hope that helps someone :)
