Setup a max nginx server

The max nxing server configuration is designed to serve several things to diffent destinations:

Steps to be done in the same machine where max instances are located:

cd /var
git clone [email protected]:UPCnet/maxserver nginx
cd /var/nginx
/var/python/python2.7/bin/python bootstrap.py -c nginx-only.cfg

Edit customizeme.cfg and modify the followig options, each in its correct section:

[hosts]
main = server.name.com
rabbitmq = rabbitserver.name.com

[ports]
nginx = 443
bigmax = 11001

[nginx-config]
certificate = /path/to/certificate
certificate-key = /path/to/certificate-priv-key

Generate a new dhparams.pem file for this server

openssl dhparam -out config/ssl/dhparam.pem 2048

then proceed to execute buildout:

./bin/buildout -c nginx-only.cfg

Create init script for the nginx instance, at /etc/init.d/nginx. Use this snippet as a template:

#!/bin/sh

Create a password file for a user named admin to be used by circus instances:

htpasswd -c /var/nginx/config/circus.htpasswd

Setup init script and start nginx instance:

chown -R pyramid.pyramid /var/nginx
