FPM Tweaking

From the nextcloud documentation. Editing the /etc/opt/remi/php74/php-fpm.d/www.conf file to match.

pm = dynamic
pm.max_children = 120
pm.start_servers = 12
pm.min_spare_servers = 6
pm.max_spare_servers = 18

Troubleshooting

caldav not rewriting

To fix the caldav issues, had to edit the rewrite rules in the htaccess file.

RewriteRule ^\.well-known/carddav /remote.php/dav/ [R=301,L]
RewriteRule ^\.well-known/caldav /remote.php/dav/ [R=301,L]

to

RewriteRule ^\.well-known/carddav https://server.com/remote.php/dav/ [R=301,L]
RewriteRule ^\.well-known/caldav https://server.com/remote.php/dav/ [R=301,L]

HSTS

Basic http conf file example.

<VirtualHost *:80>
Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"
  DocumentRoot /var/www/html/nextcloud
  ServerName  server.com

  <Directory /var/www/html/nextcloud>
    Require all granted
    AllowOverride All
    Options FollowSymLinks MultiViews
    <IfModule mod_dav.c>
      Dav off
    </IfModule>
  </Directory>
</VirtualHost>

LDAPS Server Error

When trying to enable LDAPS lookup I would run into server errors. Needed to disable the config

sudo -u apache php74 /var/www/html/nextcloud/occ ldap:show-config
sudo -u apache php74 /var/www/html/nextcloud/occ ldap:set-config s01 ldapConfigurationActive 0
