Installation Guide

Installing Tiny Tiny RSS for the first time

Before you begin, you’ll need to verify the following:

You need access to a hosting/VDS running a http server and a database (mysql or postgresql). Your database should properly support unicode.
You will need to acquire database credentials, i.e. login, password, and a database name. If you don’t have a database already created, you need to do so before installing. Tiny Tiny RSS can coexist with other applications in a shared database, creating a dedicated one is not necessary.
Your http server should be running PHP version 5.4 or later. Enabling PHP opcode cache is recommended. See also: PhpCompatibilityNotes.
The manual assumes you have basic knowledge of Git SCM.

After you have gone through the above list, you can proceed to the installation.

Clone tt-rss repository using Git

git clone https://tt-rss.org/git/tt-rss.git tt-rss

Alternatively, you can clone the repository on your local machine and upload files to the server using FTP or any other means available to you.

Verify that you can open http://yoursite/tt-rss/install/
Proceed with the installation using the easy installer. It will ask your database credentials and a full URL on which tt-rss will be accessed, for example http://yoursite/tt-rss/install/. It is required that the URL is an externally accessible one (if any), don’t use localhost there, it will break PUSH support. If you are deploying tt-rss on LAN, you can disregard this requirement.
Easy installer will generate config.php for you, after you have entered your database credentials and initialized tt-rss database. You will need to either copy text from the installer and paste it into config.php on the server, or, if possible, the installer will be able to do it for you automatically.
It is suggested that you read through config.php to see if you need to enable additional functionality or change default configuration values.
After finishing with the installer, open your Tiny Tiny RSS installation at http://yoursite/tt-rss/ and login with default credentials (username: admin, password: password).
Go to preferences and change your password!
You will also need to decide on the method tt-rss uses to update feeds. This is a separate topic, outlined in UpdatingFeeds.
If all went well, you may proceed to use tt-rss normally. Create a separate non-admin user, login under it, and start importing your feeds, subscribing, and configure it to your taste.
That’s all!

Don’t forget to read UpdatingFeeds otherwise your feeds won’t update automatically.

Take a look at available plugins

There are many plugins written for tt-rss. You can see the list here: Plugins.

Upgrading Tiny Tiny RSS

It is highly recommended to temporarily disable any third party themes and user CSS customizations before upgrading. Don’t forget to empty your browser cache if you experience weird bugs right after upgrading.

Note that you should upgrade to the latest version available, installing intermediate releases sequentially is not needed.

Upgrading with Git

Change to tt-rss directory on your server and run:

git pull origin master

That’s it. Proceed to next section.

Merging new config.php directives and updating the database

After the files have been upgraded by newer versions, open tt-rss. It may complain about missing directives in config.php. If that happens, you will need to either merge new stuff from config.php-dist to your config.php or remove config.php and rerun the installer (take note to copy previous value of FEED_CRYPT_KEY if you have feeds with authentication enabled).

DO NOT INITIALIZE DATABASE when upgrading. This will remove all your tt-rss data.

Afterwards, you may be redirected to the database updater. Log in with admin credentials and follow instructions.

Finishing that, you should be able to use tt-rss normally by logging in with your normal account.

Post-upgrade tasks

You might need to clear your browser cache if you experience CSS or script-related issues, older scripts might have stuck in it.
Do not copy cache directories from your old tt-rss version, it is unnecessary and potentially creates problems if you don’t preserve file modification times.
If you are using an accelerator like php-apc you might need to restart apache if older cached versions of PHP files got stuck in cache (this happens rarely, but is a possibility).
