This page documents my attempt to install Seaside as loadbalanced configuration with multiple squeak images under OpenVZ

Create VE

# download template
root@mljac:~# cd /var/lib/vz/template/cache
root@mljac:~# wget http://download.openvz.org/template/precreated/contrib/debian-5.0-i386-minimal.tar.gz

root@mljac:~# vzctl create 1001 --ostemplate debian-5.0-i386-minimal --ipadd 10.0.0.1 --hostname gw.rot13.org

# configure
root@mljac:~# vzctl set 1011 --nameserver 192.168.1.2 --save

Use something like vz-nat.sh to configure NAT on your OpenVZ machine.

root@seaside:/srv# chown -R squeak:squeak Seaside-2.8-578.app/

Startup

Seaside.sh - use something like this script to start headless squeak.

Actual -headless option didn't seem to work for me

Monitoring

We will be using monit, light-weight process monitor written in C to monitor servers on our virtual machine. It will do startup of our services, monitor load and report alerts.

For it to work, we need to have a script which will start/stop squeak.

Test

open http://hostname:8080/seaside/
