Requirements

The installer checks all of this for you on its first screen and will not go on until what is required is in place. Checking beforehand saves a round trip.

PHP #

• PHP 8.2 or newer.
• These extensions, all required: bcmath, curl, dom, intl, json, mbstring, openssl, pdo and simplexml.
• A database driver for the database you will use: pdo_mysql (MySQL or MariaDB) or pdo_pgsql (PostgreSQL). One is enough.
• Optional: fileinfo and zip. Without zip, some plugin and update features that open archives are not available.

Database #

• MySQL, MariaDB or PostgreSQL.
• An empty database, and a user that can create tables in it. Nothing is written until the connection works.

Folders the web server can write to #

• system/ (logs, caches, sessions and backups)
• config/ (the installer writes your database connection and your keys here)

The web server #

• Point the web server's document root at LBM's public/ folder, not at the project folder. Everything else (code, config/, system/) must not be reachable from the web.
• Use HTTPS. LBM is built for it: session cookies, payments and the licence check expect it.
• A way to run a command every minute: cron on Linux, or the Task Scheduler on Windows (see the scheduler). Without it invoices are not raised and queued email is not sent.

Checking your PHP #

From a terminal on the server:

php -v
php -m

php -m lists the extensions that are loaded. Make sure the command-line PHP is the same version the web server uses: hosts often have several.

Memory and time #

The defaults of a normal hosting plan are enough to run LBM. Large imports and updates are the only jobs that need more time or memory; if one stops part-way, raise memory_limit and max_execution_time for the command line first.
