pleroma/installation/pleroma-apache.conf

# default Apache site config for Pleroma
#
# needed modules: define headers proxy proxy_http proxy_wstunnel rewrite ssl
# optional modules: cache cache_disk
#
# Simple installation instructions:
# 1. Install your TLS certificate, possibly using Let's Encrypt.
# 2. Replace 'example.tld' with your instance's domain wherever it appears.
# 3. This assumes a Debian style Apache config. Copy this file to
#    /etc/apache2/sites-available/ and then add a symlink to it in
#    /etc/apache2/sites-enabled/ by running 'a2ensite pleroma-apache.conf', then restart Apache.
#
# Optional: enable disk-based caching for the media proxy
# For details, see https://git.pleroma.social/pleroma/pleroma/wikis/How%20to%20activate%20mediaproxy
#
# 1. Create the directory listed below as the CacheRoot, and make sure
#    the Apache user can write to it.
# 2. Configure Apache's htcacheclean to clean the directory periodically.
# 3. Run 'a2enmod cache cache_disk' and restart Apache.
