#Nginx Accelerator
Drop-in page caching using nginx, lua, and memcached.
##Features
- Listens to Cache-Control max-age header
- The memcached key is the URI (easy to expire on demand)
- Really, really fast
##Requirements
You'll need an nginx build with the following modules:
##Configure nginx
###nginx.conf
Drop the following line in any location directive:
access_by_lua "require('accelerator').access()";
For example:
http {
server {
listen 8080;
location = / {
access_by_lua "require('accelerator').access()";
}
}
}
The TTL is based on Cache-Control: max-age, but defaults to 10 seconds.
To configure your memcached connection information:
access_by_lua "require('accelerator').access({ host='127.0.0.1', port=11211 })";
Ruby client
Install gem
gem install accelerator
Example
cache = Accelerator.new("localhost:11211")
cache.get("/test")
cache.set("/test", "body")
cache.delete("/test")
cache.expire("/test", 10)
Running specs
###Install Lua and Moonscript
brew install lua
brew install luarocks
luarocks build http://moonscript.org/rocks/moonscript-0.2.3-2.rockspec
Add moonscript to your path:
export PATH=$PATH:/usr/local/lib/luarocks/bin/
###Install nginx-accelerator rock via luarocks
git clone git://github.com/winton/nginx-accelerator.git
cd nginx-accelerator
luarocks make
###Install PCRE
brew update
brew install pcre
###Install OpenResty (nginx)
curl -O http://openresty.org/download/ngx_openresty-1.2.6.6.tar.gz
tar xzvf ngx_openresty-1.2.6.6.tar.gz
cd ngx_openresty-1.2.6.6/
Get your PCRE version:
brew info pcre
Replace VERSION below with the PCRE version:
./configure --with-luajit --with-cc-opt="-I/usr/local/Cellar/pcre/VERSION/include" --with-ld-opt="-L/usr/local/Cellar/pcre/VERSION/lib" --prefix=~/OpenResty
make
make install
###Start nginx
cd nginx-accelerator
./nginx/start
