PHP requirements

Host installations are not supported starting 2021. Consider using Docker when planning new tt-rss installations.
The following applies to host installations only, updates are handled out of the box if using recommended dockerized setup. The following list may be outdated.
This document is considered deprecated.

You will need PHP 7.1 (or newer) with the following modules enabled:

PDO, with support for PostgreSQL or MySQL depending on the database server used (some distributions need both PDO and database-specific packages, i.e. php-pdo and php-pgsql)
JSON
XML (DOMDocument, DOMXpath)
Internationalization (intl)
mbstring
fileinfo

You will also need a PHP command line interpreter (to run update daemon and other CLI tools).

CURL (highly recommended, just install it) OR support for remote fopen()
POSIX functions (for the multiprocess update daemon, otherwise not needed)
GD (needed by some plugins)
Some kind of opcode cache/accelerator (depends on PHP version: php5-apc, php7-opcache, etc)

If your PHP install is missing any of the required modules tt-rss should notify you on startup.
Plugins may have additional dependencies i.e. several bundled plugins require CURL.

$ sudo apt install php7.0-cli php7.0-curl php7.0-mbstring \
    php7.0-json php7.0-intl php7.0-gd php7.0-pgsql php7.0-xml php7.0-opcache

If you’re starting from scratch you will also likely need several other packages, including httpd (e.g. nginx) and FPM.

Note: Don’t forget to enable opcache in php.ini if it’s not enabled by default.
