Replication and tile expire scripts from German tileserver
This repository contains the scripts which are used on the German tileservers for database replication using pyosmium-get-changes and osm2pgsql. These scripts will also trigger the tile expire mechanism from the output created by osm2pgsql.
The machines are currently running Debian GNU/Linux 10 (buster) and most of the software running there is available directly from the distribution.
Exceptions are:
- osml10n https://github.com/giggls/mapnik-german-l10n
- tirex https://github.com/openstreetmap/tirex
- libapache2-mod-tile https://github.com/openstreetmap/mod_tile/
Provided scripts
whichdiff.pl
A perl script to determine the replication number for the first sequence. This is needed for bootstraping the replication process.
expiremeta.pl
A perl script which will mark all meta-tiles read from osm2pgsql tile expire file for re-rendering.
expirehrb
A shell script which will mark our special small area Sorbian meta-tiles for re-rendering based on the ones marked by expiremeta.pl.
osm-replicate.service
Systemd service-file for running replicate-loop.sh
osm-replicate.timer
Systemd timer-file for calling osm-replicate.service
replicate-loop.sh
A shell script which fetches diff-files from OSM Planet server using pyosmium-get-changes and feed them to osm2pgsql afterwards. It will also call tile expire scripts if requested. This script is intended to be called from a cronjob or (recommend) from the provided systemd service and timer files. If you intend to use this for your own tileserver you will likely need to slightly adapt this to your own requirements.
