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 Ubuntu 16.04 LAMP VPS using Apache web server, PHP 7.0, and a MariaDB database.
We will start by adding a new
First, log into your server as
Add a new user called
user1 (or your preferred username):
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
Now check the
/etc/sudoers file to make sure that the
sudoers group is enabled:
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
usermod -aG sudo user1
We can verify the
user1 group membership and check that the
usermod command worked with the
Now use the
su command to switch to the new sudo user
su - user1
The command prompt will update to indicate that you are now logged into the
user1 account. You can verify this with the
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
root account (which will disconnect your
You can now
ssh into the server instance from your local host using the new non-root sudo user
If you want to execute sudo without having to type a password every time, then open the
/etc/sudoers file again, using
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:
Before installing any packages on the Ubuntu server instance, we will first update the system.
Make sure you are logged into the server using a non-root sudo user and run the following commands:
sudo apt-get update sudo apt-get -y upgrade
Install the Apache web server:
sudo apt-get -y install apache2
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
DocumentRoot configuration option should look like this:
We now need to enable the
mod_rewrite Apache module, so ensure that your Apache default 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
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
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
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.
Install MySQL database server:
sudo apt-get -y install mysql-server
During the MySQL server installation, make sure you enter a secure password for the MySQL
root user. This
root user is different to the
root user in Ubuntu as it is only used for connecting to your database server with full privileges.
Start and enable MySQL server to execute automatically at boot time.
sudo systemctl enable mysql sudo systemctl start mysql
Secure your MySQL server installation:
When prompted, enter the password you created for the MYSQL
root user during installation. Simply answer "Y" to all of the other yes/no questions as the default suggestions are the most secure options.
Log into the MySQL shell as the MySQL
root user by running the following command.
sudo mysql -u root -p
To access the MySQL command prompt, simply enter the MySQL
root password when prompted.
Run the following queries to create a MySQL 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.
Change your current working directory to the default web directory.
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:
wget to download the BigTree CMS installation package.
sudo wget https://www.bigtreecms.org/files/installers/bigtree-4.2.19.zip
Please note: The above BigTree CMS package URL was correct at the time of writing, but 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.
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 ./
Restart Apache again.
sudo systemctl restart apache2
Now we're ready to move on to the final step.
It's time to visit the IP address of your server instance in your browser, or, if you've already configured your Vultr 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 Vultr instance IP address into your browser address bar, followed by
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
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:
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.
