Sitemap Generation

See original documentation at: http://gio.blog.archive.org/2015/02/02/ol-sitemap-generation/ http://gio.blog.archive.org/2015/02/04/ol-how-to-generate-the-sitemaps/

Data Dumps

Sitemaps are generated on ol-home using the latest data dump ol_dump.txt.gz as the source file. See Generating Data Dumps for more on generating ol_dump

The last dump is available at: http://openlibrary.org/data/ol_dump_works_latest.txt.gz for more details, you can see https://openlibrary.org/developers/dumps.

Generating Sitemaps

To generate the Sitemap, execute this code on ol-home:

ssh ol-home
cd /1/var/tmp  # this way you can rsync it from rsync://ol-home/var_1/tmp/
python /1/var/lib/openlibrary/deploy/openlibrary/openlibrary/data/sitemap.py ol_dump_works_latest.txt.gz
# or is this the right script? /opt/openlibrary/openlibrary/scripts/2009/01/sitemaps/sitemap.py

Making Sitemaps Live

After the sitemap is generated you need to place it in /1/var/lib/openlibrary/sitemaps as defined in /olsystem/etc/nginx/sites-available/openlibrary.conf on ol-www1.

location ~ ^/static/(docs|tour|sitemaps|jsondumps|images/shelfview|sampledump.txt.gz)(/.*)?$ {
    root /1/var/lib/openlibrary/sitemaps;
    autoindex on;
    rewrite ^/static/(.*)$ /$1 break;
}

You can do this using rsync:

sudo rsync -av rsync://ol-home/var_1/tmp/sitemaps/sitemaps /1/var/lib/openlibrary/sitemaps/

Verify Sitemaps Available

echo "Ensure that the file dates on servers ($SERVERS) are the first day of the current month."

Sitemaps on ol-covers0 were last updated on 2023-07-01.
Sitemaps on ol-www0 were last updated on 2023-07-01.
Ensure that the file dates on servers (ol-covers0 ol-www0) are the first day of the current month.
