This Readme covers installation of the LORIS v20.* release on Ubuntu. (CentOS Readme also available).

Please consult the LORIS Wiki Setup Guide notes on this Install process for more information not included in this Readme. The LORIS Developers mailing list may also provide installation guidance not covered in the Wiki.

• LINUX (supported on Ubuntu 14+ and CentOS 6.5)
• Apache2
• MySQL 5.7
• PHP 7.2
• Package manager (for LINUX distributions)
• Composer : should be run with --no-dev option

Important:

• If you are upgrading your LORIS, you'll also want to upgrade to both PHP 7.2 and MySQL 5.7.
• Composer should be run with --no-dev option unless you are an active LORIS developer.

Consult the LORIS Wiki page on this Install process for more information.

1. Set up LINUX user lorisadmin and create LORIS base directory:

   sudo useradd -U -m -G sudo -s /bin/bash lorisadmin
   sudo passwd lorisadmin
   su - lorisadmin
   

   Important ⇾ All steps from this point forward must be executed by lorisadmin user

   sudo mkdir -m 775 -p /var/www/$projectname
   sudo chown lorisadmin.lorisadmin /var/www/$projectname
   

   $projectname ⇾ "loris" or one-word project name

2. Get code: Download the latest release from the releases page and extract it to /var/www/$projectname

3. Run installer script to install core code, and libraries. The script will prompt for information and so that it can create directories automatically.

   For more information, please read the Installing Loris wiki page.

   cd /var/www/$projectname/tools
   ./install.sh
   

4. Apache configuration and restart LORIS requires Apache's mod_rewrite module to rewrite its URLs. Enable this module, then restart Apache:

   sudo a2enmod rewrite
   sudo service apache2 reload
   

5. Go to http://localhost/installdb.php and follow the instructions to finalize LORIS installation.

   Note: Apache config files will be installed as *.conf, per Ubuntu 14.04. If running an earlier version of Ubuntu, rename these files, then run the following commands. After, restart Apache.

   sudo a2dissite default
   sudo a2ensite $projectname
   

6. Follow the Setup Guide in the LORIS Wiki to complete your post-installation setup and configuration, and for more documentation.
