Seaside cluster: Revision 19
{toc: }
This page documents my attempt to install Seaside as loadbalanced configuration with multiple squeak images under OpenVZ ^ Create VE .pre # 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 .pre Use something like {file: vz-nat.sh} to configure NAT on your OpenVZ machine. ^ Seaside .pre # dependencies root@seaside:/srv# apt-get install unzip root@seaside:/srv# wget -nd -nH http://www.seaside.st/distributions/Seaside-2.8.3.app.zip root@seaside:/srv# unzip Seaside-2.8.3.app.zip Archive: Seaside-2.8.3.app.zip root@seaside:/srv# ln -s Seaside-2.8-578.app seaside Adding new group `squeak' (1000) ... Adding new user `squeak' (1000) with group `squeak' ... Not creating home directory `/home/squeak'. root@seaside:/srv# chown -R squeak:squeak Seaside-2.8-578.app/ .pre ^^ Startup {file: Seaside.sh} - use something like this script to start headless squeak. Actual `-headless` option didn't seem to work for me ^ Front-end HTTP proxy {include: [nginx]} ^ Monitoring We will be using "monit"<http://mmonit.com/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. Use following configuration: {file: monitrc} Also install following two shells scripts in `/srv' so that monit can call them to start or stop services * {file: seaside.sh} * {file: nginx.sh} .pre # check syntax root@seaside:~# /etc/init.d/monit syntax Control file syntax OK .pre And you are rady to go. * "monit@squeak1"<http://seaside.rot13.org:2812/> to view current server status ^^ Test open "http://hostname:8080/seaside/"<http://seaside.rot13.org:8080/seaside/> to test seaside ^ More info * http://onsmalltalk.com/scaling-seaside-more-advanced-load-balancing-and-publishing * http://blog.blobworks.com/2008/12/16/squeak-in-jail/ * https://bytesmith.seework.com .pre {weblog_list: } .pre |
