Rails noob journey

I've been wanting to learn Rails since ages ago, but, you know, life was getting in the way (or me, rather). A couple of weeks ago I decided to start a side-project related to another side-project. Sounds like an entry for a GitHub Graveyard, I know....

Create nginx conf.d directory

Now we need the directory where our configuration file will be. Under .ebextensions, create a directory named 'nginx', and inside it another named 'conf.d'. Then add the file you just created. Your dir structure should look like this:

.ebextensions

nginx
- conf.d
  - proxy.conf

Now, when you deploy a new version of your application, ElasticBeanstalk will automatically copy your files on the .ebextensions/nginx/conf.d/ directory to the /etc/nginx/conf.d/ directory of your instances.

This all works because the default nginx.conf file- on line 21 -specifies to include all .conf files under the conf.d directory:

# Elastic Beanstalk Nginx Configuration File user nginx; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_processes auto; worker_rlimit_nofile 200000; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; include conf.d/*.conf; map $http_upgrade $connection_upgrade { default "upgrade"; } server { listen 80 default_server; access_log /var/log/nginx/access.log main; client_header_timeout 60; client_body_timeout 60; keepalive_timeout 60; gzip on; gzip_comp_level 4; gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript; # Include the Elastic Beanstalk generated locations include conf.d/elasticbeanstalk/*.conf; } }

The directives from the .conf file will be added to the http block of the default configuration.

If you need to add directives to the server block you will need to add .conf files to the elasticbeanstalk folder (see line 39 of previous Gist). That dir structure would look:

.ebextensions

nginx
- conf.d
  - proxy.conf
- elasticbeanstalk
  - my_other_conf.conf

Same can be done for an Apache proxy. The difference is on the directory structure. For Apache your structure should be this:

.ebextensions

httpd
- conf
  - proxy.conf
