Installing Pier on Ubuntu

Installing Pier on Ubuntu Organic Design procedure

Set Up a Pier Image

• Download Pier-2.0-OneClick.zip from http://www.piercms.com/download
• Unzip into any directory, but probably /var/www/domains/Pier.app for an OD install
• As root, change ownership to www-data:

chown -R www-data:www-data Pier.app

• Edit /etc/rc.local and add the following BASH script just before exit 0 (note you will need to change paths if you unzipped into a directory other than /var/www/domains)

#!/bin/bash
# settings
USER="www-data"
VM="/var/www/domains/Pier.app/Contents/Linux/squeakvm"
VM_PARAMS="-mmap 256m -vm-sound-null -vm-display-null"
IMAGE="/var/www/domains/Pier.app/Contents/Resources/Pier.image"
# start the vm
exec \
setuidgid "$USER" \
"$VM" $VM_PARAMS "$IMAGE"

• Restart
• Navigate to http://organicdesign.co.nz:8080
• To start Pier manually, as root:

cd /var/www/domains/Pier.app ./Pier.sh

Serve Pier Content Alongside Apache

This is assuming an OD server, as above.

• Add pier.organicdesign.co.nz to /etc/hosts
• As root, enable proxy:

a2enmod proxy proxy_http

• Then edit /etc/apache2/mods-enabled/proxy.conf, by adding Allow from organicdesign.co.nz as below:

<IfModule mod_proxy.c>

# If you want to use apache2 as a forward proxy, uncomment the
# 'ProxyRequests On' line and the <Proxy *> block below.
# WARNING: Be careful to restrict access inside the <Proxy *> block.
# Open proxy servers are dangerous both to your network and to the
# Internet at large.
#
# If you only want to use apache2 as a reverse proxy/gateway in
# front of some web application server, you DON'T need
# 'ProxyRequests On'.

<Proxy *>
        AddDefaultCharset off
        Order deny,allow
#        Deny from all
#        Allow from .example.com
        Allow from organicdesign.co.nz
</Proxy>

# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing Via: headers)
# Set to one of: Off | On | Full | Block
ProxyVia On

</IfModule>

• Finally add, at the top of the mod_rewrite in /etc/apache2/sites-available/default, directly under RewriteEngine On:

ProxyPreserveHost On RewriteCond %{HTTP_HOST} ^pier\.organicdesign.co.nz RewriteRule (.*) http://organicdesign.co.nz:8080/$1 [P,L]
