Redaxscript 3.2 CMS is a modern and ultra lightweight, free and open source Content Management System (CMS) with rocket-fast performance. The Redaxscript 3.2 CMS object relational mapper and fluent query builder provide a preconceived and standardised abstraction layer for SQLite, MSSQL, MySQL and PostgreSQL databases. Developers can execute a useful collection of powerful commands from the terminal or browser, allowing automation of installations, backups, imports and many other useful tasks, resulting in a flexible, efficient, and extensible system architecture that helps developers achieve maximum productivity and application performance.

In this tutorial we are going to install Redaxscript 3.2 CMS on an Ubuntu 16.04 LAMP VPS using Apache web server, PHP 7.0, and a MariaDB database.

Prerequisites

  • A clean Vultr Ubuntu 16.04 server instance with SSH access

Step 1: Add a Sudo User

First, log into your server as root:

ssh root@YOUR_VULTR_IP_ADDRESS

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 will 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_VULTR_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 the following:

exit

Step 2: Update Ubuntu 16.04 System

Before installing any packages on the Ubuntu 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 will 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, mod_deflate and mod_headers Apache modules:

sudo a2enmod rewrite deflate headers

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 Redaxscript CMS:

sudo apt-get -y install php php-gd php-mbstring php-common php-mysql php-imagick php-xml libapache2-mod-php php-curl php-tidy php-zip

Step 5: Install MySQL Server

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    

And secure your MySQL server installation:

sudo mysql_secure_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.

Step 6: Create Database for Redaxscript CMS

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 Redaxscript CMS:

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

You can replace the database name redax_db and username redax_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 Redaxscript 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 Redaxscript CMS installation package:

sudo wget https://redaxscript.com/files/releases/redaxscript-3.2.3-production-full.zip

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

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

ls -la

Remove index.html:

sudo rm index.html

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

sudo apt-get -y install unzip

Now uncompress the zip archive:

sudo unzip redaxscript-3.2.3-production-full.zip

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

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

Restart Apache again:

sudo systemctl restart apache2

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

Step 8: Complete Redaxscript CMS Installation

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 Redaxscript CMS installation page, enter your Vultr instance IP address into your browser address bar, followed by /install.php:

http://YOUR_VULTR_IP_ADDRESS/install.php

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

  1. Enter the following database values in the Setup your database section of the Installation page:

    Type:               MySQL
    Host:               localhost
    Name:               redax_db                
    User:               redax_user      
    Password:           UltraSecurePassword         
    Table Prefix:       rs_         
    
  2. Next, click on the Create your account section of the Installation page and enter appropriate Admin login details:

    Name:               <admin name>            
    User:               <admin username>
    Password:           <admin password>
    Email:              <admin email>
    
  3. When you have checked that all of the installation details are correct, simply click on Install to finalize the installation.

Once the installation script has finished you will be redirected to a default sample web page. To access the admin section, simply scroll down to the bottom of the sample web page and click on the Login link at the bottom right hand corner of the page.

Alternatively, you can access the Login page by typing the address into your browser manually:

http://YOUR_VULTR_IP_ADDRESS/login

For security reasons, make sure you delete the install.php file and templates/install directory from the webroot directory immediately:

sudo rm -rf ./templates/install ./install.php

Also, make sure the config.php file is not writable:

sudo chmod 444 ./config.php

Lastly, visit console.php in your browser:

http://YOUR_VULTR_IP_ADDRESS/console.php

Enter the console lock command to revoke public access to the console.php page:

console lock
