Nginx

NGiNX by all accounts is much more efficient than Apache, so we will probably start changing the OD server, and our server installation procedure over to NGiNX.

Installation

<bash>wget http://www.dotdeb.org/dotdeb.gpg cat dotdeb.gpg

Self-signed SSL certificates

Nginx doesn't use the basic .pem files that can be used by Apache for self-signed certificates. We need to go through the following procedure to turn the pem into key and crt files.

First we need to create a private key. Note that this process will require a pass-phrase for the key - don't worry, we'll remove it later to make things easier,

openssl genrsa -des3 -out ssl.key 1024

Now we need to create a CSR (Certificate Signing Request):

openssl req -new -key ssl.key -out ssl.csr

Now we need to remove the pass-phrase otherwise it'll prevent the web-server from restarting without it being entered (you'll need to enter the pass-phrase to remove it though),

cp ssl.key ssl-pass.key openssl rsa -in ssl-pass.key -out ssl.key

Now we can generate the actual certificate:

openssl x509 -req -days 365 -in ssl.csr -signkey ssl.key -out ssl.crt

The relevant server section can now be updated in the nginx configuration,

listen 80; listen 443 default ssl; ssl_certificate /etc/nginx/certs/ssl.crt; ssl_certificate_key /etc/nginx/certs/ssl.key;
