ASLO Node

While discussing activities.sugarlabs.org maintainability with Dogi this afternoon, he suggested that instead of thinking about web, proxy, and database nodes we create a standard ALSO node which we can adopt and tune via configs.

Components

Setup Network

Set the IP address for the each nic

/etc/networks/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 10.0.0.101
        netmask 255.255.255.0
        network 10.0.0.0
        broadcast 10.0.0.255
        gateway 10.0.0.1

#auto eth1
iface eth1 inet static
        address 10.0.0.201
        netmask 255.255.255.0
        network 10.0.0.0
        broadcast 10.0.0.255
        gateway 10.0.0.1

svn co http://svn.mozilla.org/libs/zxtm-api


Set up NFS mount points

Create directories

mkdir -p ~/files
mkdir -p ~/staging

Add the following lines to the end of `/etc/fstab'

sunjammer.sugarlabs.org:/srv/nfs/activities/files /srv/activities/files nfs rsize=8192,wsize=8192,timeo=14,intr
sunjammer.sugarlabs.org:/srv/nfs/activities/staging /srv/activities/staging nfs rsize=8192,wsize=8192,timeo=14,intr

First-time ASLO setup

Using ~/aslo/config.php as template, setup ASLO settings in file ~/site/app/config/config.php. Template file was configured for dev environment, switch it to production by setting SITE_STATE variable to production.

Setup other env defines in file ~/site/app/config/config-local.php

define('DEBUG', 0);
define('DEV', false);
define('QUERY_CACHE', true);

Create directories

mkdir -p ~/site/app/tmp/cache/persistent
mkdir -p ~/site/app/tmp/cache/models
mkdir -p ~/site/app/tmp/cache/views
mkdir -p ~/files/temp
mkdir -p ~/files/extracted
mkdir -p ~/data

~/aslo/po-compile.sh

Crontab for activities user

@hourly $HOME/aslo/cron/hourly
# do not use @daily to make sure that we start job after aslo-proxy
01 08 * * * $HOME/aslo/cron/daily

Create vhost

vim /etc/apache2/sites-available/activities.sl.org

<VirtualHost *:80 *:443>
        ServerName activities.sugarlabs.org
        ServerAlias activities2.sugarlabs.org # for test/install
        ServerAdmin webmaster@sugarlabs.org

        DocumentRoot /srv/activities/site/app/webroot

        LogFormat "%h %V %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\" \"%{HTTP_COOKIE}i\"" addons
        CustomLog /srv/activities/data/access addons
        CustomLog /var/log/apache2/all-access.log vhost_combined
        #CustomLog /var/log/apache2/performance.log performance
</VirtualHost>
