To get started with installing LEPTON CMS, follow the steps below:

Install Apache2 HTTP Server

LEPTON CMS requires a web server, and the Apache2 HTTP server is the most popular open-source web server available today. To install the Apache2 server, run the commands below:

sudo apt update
sudo apt install apache2

After installing Apache2, the commands below can be used to stop, start and enable the Apache2 service to always start up with the server boots.

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

Now that Apache2 is installed browse your browser to the URL below to test whether the web server works.

http://localhost

If you see the page above, then Apache2 is successfully installed.

Install MariaDB Database Server

LEPTON CMS also requires a database server to store its content. MariaDB is a great place to start if you want a genuinely open-source database server. To install MariaDB run the commands below:

sudo apt-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can stop, start and enable the MariaDB service to start up when the server boots.

Run these on Ubuntu 16.04 LTS

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

Run these on Ubuntu 18.10 and 18.04 LTS

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

• Enter current password for root (enter for none): Just press the Enter
• Set root password? [Y/n]: Y
• New password: Enter password
• Re-enter new password: Repeat password
• Remove anonymous users? [Y/n]: Y
• Disallow root login remotely? [Y/n]: Y
• Remove test database and access to it? [Y/n]:  Y
• Reload privilege tables now? [Y/n]:  Y

Once MariaDB is installed, run the commands below to test whether the database server was installed.

sudo mysql -u root -p

Type the root password when prompted.

The server was successfully installed if you see a similar screen.

Install PHP 7.2 and Related Modules

LEPTON CMS is a PHP-based CMS, and PHP is required. However, PHP 7.2 may not be available in Ubuntu’s default repositories. To run PHP 7.2 on Ubuntu 16.04 and previous, you may need to run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2

sudo apt update

Next, run the controls below to install PHP 7.2 and related modules.

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-bcmath php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open the PHP default configuration file for Apache2.

sudo nano /etc/php/7.2/apache2/php.ini

The lines below are a good setting for most PHP-based CMS. Update the configuration file with these and save.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Every time you change the PHP configuration file, you should restart the Apache2 web server. To do so, run the commands below:

sudo systemctl restart apache2.service

Once PHP is installed, create a test file called phpinfo.php in the Apache2 default root directory to test whether it’s functioning. ( /var/www/html/)

sudo nano /var/www/html/phpinfo.php

Then type the content below and save the file.

<?php phpinfo( ); ?>

Next, open your browser and browse to the server’s hostname or IP address, followed by phpinfo.php

http://localhost/phpinfo.php

You should see the PHP default test page.

Create LEPTON CMS Database

Once you’ve installed all the packages required for LEPTON CMS to function, continue below to start configuring the servers. First, run the commands below to create a blank LEPTON CMS database.

To log on to the MariaDB database server, run the commands below.

sudo mysql -u root -p

Then create a database called lepton.

CREATE DATABASE lepton;

Create a database user called leptonuser with a new password

CREATE USER 'leptonuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON lepton.* TO 'leptonuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Download LEPTON CMS Latest Release

To get LEPTON CMS’s latest release, you may want to get it from its download page below. At the time of this writing, the current version is 4.1.0.

https://lepton-cms.org/english/download.php

Extract the downloaded content and copy it to the Apache2 root directory.

cd ~/Downloads
sudo unzip -d /var/www/html/lepton ~/Downloads/LEPTON_stable_4.1.0.zip

Then run the commands below to set the correct permissions for the LEPTON CMS root directory and give Apache2 control.

sudo chown -R www-data:www-data /var/www/html/lepton/
sudo chmod -R 755 /var/www/html/lepton/

Configure Apache2

Finally, configure the Apahce2 site configuration file for LEPTON CMS. This file will control how users access WebsiteBaker content. Run the commands below to create a new configuration file called lepton.conf.

sudo nano /etc/apache2/sites-available/lepton.conf

Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and directory root location.

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot /var/www/html/lepton/upload
     ServerName example.com
     ServerAlias www.example.com

     <Directory /var/www/html/lepton/upload/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
    
</VirtualHost>

Save the file and exit.

Enable the LEPTON CMS and Rewrite Module

After configuring the VirtualHost above, please enable it by running the commands below.

sudo a2ensite lepton.conf
sudo a2enmod rewrite
sudo systemctl restart apache2.service

Then open your browser and browse to the server domain name. You should see the LEPTON CMS setup wizard complete. Please follow the wizard carefully.

http://example.com/install

Then follow the on-screen instruction. Next, go to steps two and three and validate that your environment meets the minimum setup.

Set required LEPTON configuration parameters. Some parameters are required to be set before LEPTON installation. After the installation, log in to the administration console and configure the remaining parameters. This should be your very first administrator task.

Step 4 sets up the database connection info you created above and continues.

In step 5, create a backend admin account and continue.

After that, LEPTON should be installed and ready to use.

Congratulation! You have successfully installed LEPTON CMS on Ubuntu 16.04 | 18.04 and 18.10.
