Responsibilities

Nagios Plugin Team responsible for:

• website, including drupal and backups
• mysql
• user administration

Login

ssh -p 1022 {user}@nagiosplugins.opsera.com

Sites

There are three sites:

• dev.nagiosplugins.org
• staging.nagiosplugins.org
• nagiosplugins.org

These are under /srv/www.

Site promotion


cd /srv/www
copy_site {site name}

This will copy the site across, taking files + database if applicable.

Scripts

Stored under /usr/local/nagiosplugin/bin. TODO: use git to version control - speak to Thomas

Man page updates

This is invoked from a cron job by the nagiosplugins user, running the /home/nagiosplugins/bin/np_build_from_sf script. This calls the update_man_pages script which updates the drupal database with the latest --help output.

If a new plugin is added, the script will fail. You need to manually add the page in drupal and then re-run. When adding a page:

• Add a child page to http://nagiosplugins.org/man
• Set the title to the name of the plugin
• Add some text in the body
• Set the URL path to man/{nameofplugin}
• Set "no promote to front page"

Emails get sent to Ton on failure.

Backups

Run from tonvoon's crontab at 3am UK time. Backs up into /srv/backups, files and database. Retains last 30 backups.

Directory is rsync onto Ton's home server.

Restores


gunzip -c /srv/backups/nagiosplugins.latest.db.gz | mysql -u root dev
cd /srv/www/dev.nagiosplugins.org
tar --gzip -xvf /srv/backups/nagiosplugins.latest.tar.gz


Then check http://dev.nagiosplugins.org

Users and groups

Will have two groups:

• nagiosplugins - all team members
• npadmin - team leader + deputy

Only npadmin have sudo access to root (to review).

Will have 1 user called nagiosplugins to handle cronjobs and drupal. Any one in the nagioplugins team can switch to this application user:

sudo su - nagiosplugins


New users

Only npadmin group can do.

sudo useradd -g nagiosplugins -s /bin/bash -d /home/{user} -m {user}
sudo passwd {user} # Set to some random one
sudo usermod -G npadmin {user} # If team admin


User should then sort out their ssh keys and password:

passwd
ssh -p 1022 {user}@nagiosplugins.opsera.com
mkdir .ssh
exit
scp -P 1022 {id_dsa.pub} {user}@nagiosplugins.opsera.com:.ssh/authorized_keys
ssh -p 1022 {user}@nagiosplugins.opsera.com # Check key works


Removing users


sudo userdel {user}
