ftw.maintenanceserver

Provides a simple server serving a static directory, which can be configured as haproxy backup server, kicking in when all normal servers are offline.

How it works

It is simple HTTP server, serving a static directory. All requests which match no file in the static directory are responded with the index.html which is expected to be placed in the static directory.

This is useful when a user is visiting the page at any URL while the maintenance server is activated. The user then stays at the same URL and can refresh until the system is back online and he is at the same place as he was before.

Installation

The server can be installed using zc.buildout, which generates a pre configured bin/maintenance script:

[buildout]
parts += maintenance

[maintenance]
recipe = zc.recipe.egg
eggs = ftw.maintenanceserver
arguments = '${buildout:directory}/static', 8088

HAProxy configuration

When using HAProxy the server can be simply configured as backup server, which will only be used when all "normal" servers are offline:

backend plone
server plone1 127.0.0.1:8080 cookie p1 check downinter 15s maxconn 5 rise 1 slowstart 60s
server plone2 127.0.0.1:8081 cookie p2 check downinter 15s maxconn 5 rise 1 slowstart 60s
server maintenance 127.0.0.1:8088 check backup
