BigTree CMS 4.2 is a fast and lightweight, free and open source, enterprise-grade content management system (CMS) with extensive and extensible content management capabilities. Notable BigTree CMS features include: full data caching, advanced content governance, integrated site integrity monitoring, powerful add-on extensions, and fine-grained user and permissions management.

In this tutorial we are going to install BigTree CMS 4.2 on a Debian 9 LAMP VPS using Apache web server, PHP 7.1, and a MariaDB database.

Prerequisites

  • A clean IT Web Services Debian 9 server instance with SSH access

Step 1: Add a Sudo User

We will start by adding a new sudo user.

First, log into your server as root:

ssh root@YOUR_INSTANCE_IP_ADDRESS

The sudo command isn’t installed by default in the IT Web Services Debain 9 server instance, so we will first install sudo:

apt-get -y install sudo

Now add a new user called user1 (or your preferred username):

adduser user1

When prompted, enter a secure and memorable password. You will also be prompted for your “Full Name” and some other details, but you can simply leave them blank by pressing Enter.

Now check the /etc/sudoers file to make sure that the sudoers group is enabled:

visudo

Look for a section like this:

%sudo        ALL=(ALL:ALL)       ALL

This line tells us that users who are members of the sudo group can use the sudo command to gain root privileges. It should be uncommented by default so you can simply exit the file.

Next we need to add user1 to the sudo group:

usermod -aG sudo user1

We can verify the user1 group membership and check that the usermod command worked with the groups command:

groups user1

Now use the su command to switch to the new sudo user user1 account:

su - user1

The command prompt will update to indicate that you are now logged into the user1 account. You can verify this with the whoami command:

whoami

Now restart the sshd service so that you can login via ssh with the new non-root sudo user account you have just created:

sudo systemctl restart sshd

Exit the user1 account:

exit

Exit the root account (which will disconnect your ssh session)

exit

You can now ssh into the server instance from your local host using the new non-root sudo user user1 account:

ssh user1@YOUR_INSTANCE_IP_ADDRESS

If you want to execute sudo without having to type a password every time, then open the /etc/sudoers file again, using visudo:

sudo visudo

Edit the section for the sudo group so that it looks like this:

%sudo   ALL=(ALL) NOPASSWD: ALL

Please note: Disabling the password requirement for the sudo user is not a recommended practice, but it is included here as it can make server configuration much more convenient and less frustrating, especially during longer systems administration sessions. If you are concerned about the security implications, you can always revert the configuration change to the original after you finish your administration tasks.

Whenever you want to log into the root user account from within the sudo user account, you can use one of the following commands:

sudo -i
sudo su -

You can exit the root account and return back to your sudo user account any time by simply typing:

exit

Step 2: Update Debian 9 System

Before installing any packages on the Debian server instance, we will first update the system.

Make sure you are logged in to the server using a non-root sudo user and run the following commands:

sudo apt-get update
sudo apt-get -y upgrade

Step 3: Install Apache Web Server

Install the Apache web server:

sudo apt-get -y install apache2

Then use the systemctl command to start and enable Apache to execute automatically at boot time:

sudo systemctl enable apache2
sudo systemctl start apache2

Check your Apache default site configuration file to ensure that the DocumentRoot directive points to the correct directory: 

sudo vi /etc/apache2/sites-enabled/000-default.conf

The DocumentRoot configuration option should look like this:

DocumentRoot "/var/www/html"

We now need to enable the mod_rewrite Apache module, so ensure that your Apache deafult site configuration file is still open, and add the following Directory Apache directives just before the closing </VirtualHost> tag, so that the end of your configuration file looks like this:

    <Directory /var/www/html/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

The most important directive shown above is AllowOverride All.

Now save and exit the file, and enable the mod_rewrite Apache module:

sudo a2enmod rewrite

We will restart Apache at the end of this tutorial, but restarting Apache regularly during installation and configuration is certainly a good habit, so let’s do it now:

sudo systemctl restart apache2

Step 4: Install PHP 7.0

We can now install PHP 7.0 along with all of the necessary PHP modules required by BigTree CMS:

sudo apt-get -y install php php-gd php-mbstring php-common php-mysql libapache2-mod-php php-curl

Big Tree CMS requires us to modify the default PHP settings, so open php.ini:

sudo vi /etc/php/7.0/apache2/php.ini

Add or edit the following PHP options:

short_open_tag = On
upload_max_filesize = 32MB

Once you have added the above options, save and exit the file.

Step 5: Install MariaDB (MySQL) Server

Debian 9 defaults to using MariaDB database server, which is an enhanced, fully open source, community developed, drop-in replacement for MySQL server.

Install MariaDB database server:

sudo apt-get -y install mariadb-server

Start and enable MariaDB server to execute automatically at boot time:

sudo systemctl enable mariadb
sudo systemctl start mariadb

Secure your MariaDB server installation:

sudo mysql_secure_installation

The root password will probably be blank, so simply hit enter when prompted for the root password.

When prompted to create a MariaDB/MySQL root user, select “Y” (for yes) and then enter a secure root password. Simply answer “Y” to all of the other yes/no questions as the default suggestions are the most secure options.

Step 6: Create Database for BigTree CMS

Log into the MariaDB shell as the MariaDB root user by running the following command:

sudo mariadb -u root -p

To access the MariaDB command prompt, simply enter the MariaDB root password when prompted.

Run the following queries to create a MariaDB database and database user for BigTree CMS:

CREATE DATABASE bigtree_db CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'bigtree_user'@'localhost' IDENTIFIED BY 'UltraSecurePassword';
GRANT ALL PRIVILEGES ON bigtree_db.* TO 'bigtree_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

You can replace the database name bigtree_db and username bigtree_user with something more to your liking, if you prefer. Also, make sure that you replace “UltraSecurePassword” with an actually secure password.

Step 7: Install BigTree CMS Files

Change your current working directory to the default web directory:

cd /var/www/html/

If you get an error message saying something like 'No such file or directory' then try the following command:

cd /var/www/ ; sudo mkdir html ; cd html

Your current working directory will now be: /var/www/html/. You can check this with the pwd (print working directory) command:

pwd

Now use wget to download the BigTree CMS installation package:

sudo wget https://www.bigtreecms.org/files/installers/bigtree-4.2.19.zip

Please note: You should definitely check for the most recent version by visiting the BigTree CMS download page.

List the current directory to check that you have successfully downloaded the file:

ls -la

Let’s quickly install unzip so we can unzip the file:

sudo apt-get -y install unzip

Now uncompress the zip archive:

sudo unzip bigtree-4.2.19.zip

Move all of the installation files to the web root directory:

sudo mv BigTree-CMS/* /var/www/html

Change ownership of the web files to avoid any permissions problems:

sudo chown -R www-data:www-data * ./

We also need to make sure that the webroot is writable:

sudo chmod 777 ./

Let’s restart Apache again:

sudo systemctl restart apache2

Now we’re ready to move on to the final step.

Step 8: Complete BigTree CMS Installation

It’s time to visit the IP address of your server instance in your browser, or, if you’ve already configured your IT Web Services DNS settings (and given it enough time to propagate) you can simply visit your domain instead.

To access the BigTree CMS installation page, enter your IT Web Services instance IP address into your browser address bar, followed by install.php:

http://YOUR_INSTANCE_IP_ADDRESS/install.php

Most of the installation options are self explanatory, but here are a few pointers to help you along:

Enter the following database values:

Hostname:       localhost
Database:       bigtree_db
Username:       bigtree_user
Password:       UltraSecurePassword

Enter the following Administrator Account details:

Email Address:  <your email address>
Password:       <a secure password>

Enter your preferred site routing options:

Routing:        Simple Rewrite Routing
URL Behaviour:  URLs End With Page Slug

Select “Install Example Site” if you want to experiment with the example site files. If you want to start with a completely fresh site then leave this box unchecked.

Click on the Install Now button to continue the BigTree CMS installation.

You will be redirected to the BigTree CMS Installation Complete page.

To access the Administration Area simply click on the admin link or enter your domain or IP address into your browser with admin/ after the URL:

http://YOUR_INSTANCE_IP_ADDRESS/admin/

Simply enter your login details to access the Administration Area.

You are now ready to start adding your content and configuring the look and feel of your site. Make sure you check out the BigTree CMS documentation for more information about how to build and configure your site.
