Install NGINX

The Centos v5.1 VM is violet.lucidsolutions.co.nz (192.168.0.60).

Installation

I couldn't easily find a nginx RPM for CentOS 5 (or RHEL), but I didn't look that hard (Update: nginx is now in EPEL).  Just use the x86_64 version from Fedora 8 updates. wget the rpm from the fedora 8 updates.
# rpm --import http://download.fedora.redhat.com/pub/fedora/linux/releases/8/Fedora/x86_64/os/RPM-GPG-KEY-fedora
# yum localinstall nginx-0.5.35-1.fc8.x86_64.rpm

Configuration

Configure the nginx service in /etc/nginx/nginx.conf. Start with a vanilla proxy, without any caching (where the proxy_pass host is direct to Zope), and then change it to go via a local Varnish cache  [2]. It is necessary to use the virtual host monster with Zope (which is why the proxy_pass line has all the 'stuff').

It is important to allow nginx (or Varnish) out to access the plone server. Add an iptables rule to /etc/sysconfig/iptables:

-A tcpOut  -p tcp -m tcp --dport 8080 --destination plone-internal.lucidsolutions.co.nz -m state --state NEW -j ACCEPT

I found that when adding large documents into plone the post would fail. This requires a client_max_body_size directive.

Run

Enable and start the service
# chkconfig nginx on
# service nginx start
