Ruby CGI scripts that I used to set up my website
|
||||
Ruby CGI scripts that I used to set up my website
|
||||
|
||||
## What is included
|
||||
|
||||
- listing.rb - generates a recursve listing of files at your preferred location
|
||||
- markdown.rb - processes markdown (partially) and converts it to HTML
|
||||
|
||||
## How to apply this to your site
|
||||
|
||||
- Drop all .rb files into your web directory root
|
||||
- Edit markdown.rb and point ROOT\_PATH to the full web directory root path
|
||||
- Edit listing.rb and point ROOT\_PATH to the full web directory root path and DIR\_PATH to the directory where markdown files are located (they have to be in adirectory under root!)
|
||||
- If you're using lighttpd:
|
||||
- Install `mod_cgi` in your config file and add "listing.rb" as an index
|
||||
```
|
||||
server.modules += ("mod_cgi")
|
||||
index-file.names += ("listing.rb")
|
||||
cgi.assign = (
|
||||
".rb" => "/usr/bin/ruby"
|
||||
)
|
||||
```
|
||||
- If you're using apache:
|
||||
- lmao idk
|
||||
- just add CGI module, make it run ruby files and make listing.rb an index
|
||||
- If you're using NGINX:
|
||||
- Install lighttpd and configure it the same way as above, but use a custom port for the server
|
||||
- Add `listing.rb` as an index file to your preferred location
|
||||
- Add a reverse proxy clause in NGINX config to proxy all .md and .rb requests to the lighttpd server
|
||||
```nginx
|
||||
...
|
||||
|
||||
# pass ruby files to lighttpd
|
||||
location ~ \.rb {
|
||||
proxy_pass http://127.0.0.1:6969;
|
||||
}
|
||||
|
||||
# pass .md files as query parameters to markdown.rb
|
||||
location ~ \.md {
|
||||
proxy_pass http://127.0.0.1:6969/markdown.rb?docfile=$uri;
|
||||
}
|
||||
|
||||
...
|
||||
```
