Ubuntu and Debian
The following instructions are for installing TAO on Ubuntu 18.04 and can easily be adapted for Debian Buster/Sid.
The following instructions are for Ubuntu 18.04 and utilize /var/www/html/tao as the working directory for installation and /var/www/html as the
DocumentRoot. Should you choose different Operating System version, another Debian-based flavor, directory location, or
DocumentRoot you will need to adjust these paths as appropriate. These instructions make the assumption that you have access to the command line. If necessary, refer to your hosting company for how to proceed if you do not have SSH access to your environment.
Make sure the server is up to date:
sudo apt update sudo apt dist-upgrade
Once the system is up to date, you will need to install the required packages to create your LAMP stack as well as the packages necessary to complete your TAO installation if they have not yet been created.
sudo apt install apache2 \ php \ php-cli \ php-common \ mysql-server \ php-xml \ php-zip \ php-curl \ php-mbstring \ libapache2-mod-php \ php-mysql \ curl \ wget \ zip \ tidy \ unzip \ composer
Install components needed to build and install php-mcrypt
sudo apt install php-dev libmcrypt-dev php-pear sudo pecl channel-update pecl.php.net sudo pecl install mcrypt-1.0.1
Add mcrypt to the extensions section of php.ini
sudo nano /etc/php/7.2/cli/php.ini extension=mcrypt.so
Create a new database and user for TAO.
sudo su - mysql create database <database>; create user '<user>'@'localhost'; set password for '<user>'@'localhost' = PASSWORD('<password>'); grant all privileges on <database>.* to '<user>@'localhost' identified by '<password>'; flush privileges; quit exit
Using the editor of your choice, you will need to configure the
ServerName as well as the directory you are installing TAO in. If you are using virtual hosts, you will need to follow the Apache instructions which can be found here.
sudo nano /etc/apache2/apache2.conf
ServerName <hostname or IP>
<Directory /var/www/html/tao> Options FollowSymLinks MultiViews AllowOverride all Allow from all </Directory>
You will also want to configure Apache to serve PHP pages first by configuring dir.conf to have index.php first.
sudo nano /etc/apache2/mods-enabled/dir.conf
Turn on the mod-rewrite module
sudo a2enmod rewrite
Verify your Apache configuration and then restart for your changes to take effect.
sudo apache2ctl configtest sudo service apache2 restart
Download the TAO Package from GitHub and prepare to install:
Change ownership to the Apache user
sudo chown -R www-data:www-data /var/www/html/tao
Ensure the correct version of composer is used. By default, the version of composer installed on Ubuntu and Debian is composer 2. Before you can install TAO you will need to downgrade this to version 1, with the following command:
sudo composer self-update --1
Install TAO components on the server utilizing composer and then change ownership of the newly created tao directory to the Apache user:
sudo cd /var/www/html/tao sudo composer install sudo chown -R www-data tao
Install MathJax on the server if necessary.
sudo wget https://hub.taotesting.com/resources/taohub-articles/articles/third-party/MathJax_Install_TAO_3x.sh sudo chmod u+x MathJax_Install_TAO_3x.sh sudo ./MathJax_Install_TAO_3x.sh
You can now complete your installation either on the command line using the following command:
sudo -u www-data php tao/scripts/taoInstall.php \ --db_driver pdo_mysql \ --db_host localhost \ --db_name <db_name> \ --db_user <user> \ --db_pass <password>\ --module_namespace http://<hostname or IP>/first.rdf \ --module_url http://<hostname or IP> \ --user_login <user> \ --user_pass <password> \ -e taoCe
in which case your TAO instance will be available at:
http://<hostname or IP>/tao
Alternatively you can install TAO in your browser by going to
http://<hostname or IP>/tao if you have followed the instructions above. If you have not followed the above instructions for your Apache configuration you will need to adjust the URL as appropriate.
