Instances run [wiki:InstallationGuidelinesApacheModWSGI WSGI] & [wiki:InstallationGuidelinesMySQL MySQL]. 1. Turn off template VM instance if on 2. SSH into the host machine If using Host1: 3. {{{cd /spare/images/images}}} 4. {{{cp 106/vm-106-disk-1.raw 1xx/vm-1xx-disk-1.raw}}} If using Host2: 3. {{{ #zcat /spare/template/vm_release.gz | dd of=/dev/data/vm-1xx-disk-1 bs=8M dd if=/dev/data/vm-106-disk-1 of=/dev/data/vm-1xx-disk-1 bs=8M }}} 4. That'll take a while. You can get it to notify progress by doing a kill -USR1 {process id of the dd} 5. start your VM after the copy is complete 6. Open VNC Console 7. read /home/INSTALL in the vm 8. Set the IP (using the spreadsheet) == Upgrading an Instance == Need to decide whether the site will be upgraded straight from Trunk, or whether upgrades are staged via a Test server. Simple upgrades can be done using the aliases: * ConfigurationGuidelines#UsefulAliases We manage complex upgrades using Fabric: 1. Add the site to [http://eden.sahanafoundation.org/browser/static/scripts/tools/fabfile.py fabfile.py] 2. If no keys generated yet, then generate some: {{{ fab generate_keys }}} 3. deploy keys {{{ fab distribute_keys }}} 4. Run the upgrade (as/when required) {{{ fab deploy }}} == Trac Maintenance == To reset tickets which have been assigned to nobody: {{{ apache2ctl stop sqlite3 /home/sahana/trac/db/trac.db UPDATE ticket SET status = 'new' WHERE owner = '' and status = 'assigned'; .q apache2ctl start }}} To clear blocks from !MathCaptcha failures: * View Blocks: http://eden.sahanafoundation.org/mathcaptcha-attempts * Clear blocks: http://eden.sahanafoundation.org/mathcaptcha-clear == Mail Queues == View queue: {{{ mailq }}} Flush queue (inc Frozen messages): {{{ exim -qff }}} == References == * [https://docs.google.com/Doc?docid=0Ac-Y6NVjUsjiZGN4a2s1Y3RfMTNnNXZjbnpoZA&hl=en_GB SysAdmin notes for Eden Infrastructure] * [https://docs.google.com/Doc?docid=0ASR82JeFPTCOZGNicWQ2cl80N2c3Y21jcGdu&hl=en_GB Foundation Infrastructure] * [https://docs.google.com/Doc?docid=0Ac-Y6NVjUsjiZGN4a2s1Y3RfMTJjdjJ3MjNnZg&hl=en_GB Contacts] == !ToDo == === Windows Installer === See if we can upgrade the [InstallationGuidelinesWindowsMaintenance Windows Installer] to Python 2.7 to have Foreign-Key support (#900) Use Esky to provide an auto-update method: * http://pyconau.blip.tv/file/3840197/ === Infrastructure Virtual Machine Template === * {{{/home/INSTALL}}} * {{{/root/ChangeTemplate.sh}}} * scripts in {{{/usr/local/bin}}} * {{{apt-get install -y python-shapely}}} * Convert to PostgreSQL/PostGIS * Update Eden * Update Web2Py (as-required) * Update OS * 90 not upgraded packages (held back) * Increase swap to 2048Mb (from 750Mb) * can we do this in image?
