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 a CentOS 7 LAMP VPS using Apache web server, PHP 7.1, and a MariaDB database.
Step 1: Add a Sudo User
First, log into your server as
Add a new user called
user1 (or your preferred username):
Next, set the password for the
When prompted, enter a secure and memorable password.
Now check the
/etc/sudoers file to make sure that the
sudoers group is enabled:
Look for a section like this:
%wheel ALL=(ALL) ALL
This line tells us that users who are members of the
wheel 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
usermod -aG wheel 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
wheel group so that it looks like this:
%wheel 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:
Step 2: Update CentOS 7 System
Before installing any packages on the CentOS 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 command:
sudo yum -y update
Step 3: Install Apache Web Server
Install the Apache web server:
sudo yum -y install httpd
Then use the
systemctl command to start and enable Apache to execute automatically at boot time:
sudo systemctl enable httpd sudo systemctl start httpd
Check your Apache configuration file to ensure that the
DocumentRoot directive points to the correct directory:
sudo vi /etc/httpd/conf/httpd.conf
DocumentRoot configuration option will look like this:
Now, let’s make sure that the
mod_rewrite Apache module is loaded. We can do this by searching the Apache base modules configuration file for the term “
Open the file:
sudo vi /etc/httpd/conf.modules.d/00-base.conf
Search for the term
mod_rewrite Apache module is loaded, you will find a configuration line looking like this:
LoadModule rewrite_module modules/mod_rewrite.so
If the above line starts with a semi-colon, you will need to remove the semi-colon to uncomment the line and load the module. This, of course, applies to any other required Apache modules too.
We now need to edit Apache’s default configuration file so that
mod_rewrite will work correctly with Redaxscript CMS.
Open the file:
sudo vi /etc/httpd/conf/httpd.conf
Then find the section that starts with
<Directory "/var/www/html"> and change
AllowOverride none to
AllowOverride All. The end result (with all comments removed) will look something like this:
<Directory "/var/www/html"> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>
Now save and close the Apache configuration file.
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 httpd
Step 4: Open Web Firewall Ports
We now need to open the default
HTTPS ports as they will be blocked by
firewalld by default.
Open the firewall ports:
sudo firewall-cmd --permanent --add-port=80/tcp sudo firewall-cmd --permanent --add-port=443/tcp
Reload the firewall to apply the changes:
sudo firewall-cmd --reload
You will see the word
success displayed in your terminal after each successful firewall configuration command.
We can quickly verify that the Apache
HTTP port is open by visiting the IP address or domain of the server instance in a browser:
You will see the default Apache web page in your browser.
Step 5: Disable SELinux (if enabled)
SELinux stands for “Security Enhanced Linux”. It is a security enhancement to Linux which allows users and administrators more control over access control. It is disabled by default on IT Web Services CentOS 7 instances, but we will cover the steps to disable it, just in case you are not starting from a clean install and it was previously enabled.
To avoid file permission problems with Redaxscript CMS we need to ensure that SELinux is disabled.
First, let’s check whether SELinux is enabled or disabled with the
If you see something like:
SELinux status: disabled then it is definitely disabled and you can skip straight to Step 6. If you see any other message, then you will need to complete this section.
Open the SELinux configuration file with your favourite terminal editor:
sudo vi /etc/selinux/config
SELINUX=disabled and then save the file.
To apply the configuration change, SELinux requires a server reboot, so you can either restart the server using the IT Web Services control panel or you can simply use the
sudo shutdown -r now
When the server reboots, your SSH session will get disconnected and you may see a message informing you about a
'broken pipe' or
'Connection closed by remote host'. This is nothing to worry about, simply wait for 20 seconds or so and then SSH back in again (with your own username and domain):
Or (with your own username and IP address):
Once you have logged back in, you should check the status of SELinux again with the
sestatus command to make sure it is properly disabled:
You should see a message saying
SELinux status: disabled. If you see a message saying
SELinux status: enabled (or something similar) you will need to repeat the above steps and ensure that you properly restart your server.
Step 6: Install PHP 7.1
CentOS 7 requires us to add an external repo in order to install PHP 7.1, so run the following command:
sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
We can now install PHP 7.1 along with all of the necessary PHP modules required by Redaxscript CMS:
sudo yum -y install php71w php71w-gd php71w-mbstring php71w-mysql php71w-xml php71w-common php71w-pdo php71w-mysqlnd
Step 7: Install MariaDB (MySQL) Server
CentOS 7 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 yum -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:
root password will be blank, so simply hit enter when prompted for the
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 8: Create Database for Redaxscript CMS
Log into the MariaDB shell as the MariaDB
root user by running the following command:
sudo mysql -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 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. (Please note that the default maximum length for usernames in MariaDB on CentOS 7 is 16 characters). Also, make sure that you replace “UltraSecurePassword” with an actually secure password.
Step 9: Install Redaxscript CMS Files
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 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:
Let’s quickly install
unzip so we can unzip the file:
sudo yum -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 apache:apache * ./
Restart Apache again:
sudo systemctl restart httpd
Now we’re ready to move on to the final step.
Step 10: 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 IT Web Services 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 IT Web Services 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 in the
Setup your databasesection of the
Type: MySQL Host: localhost Name: redax_db User: redax_user Password: UltraSecurePassword Table Prefix: rs_
Next, click on the
Create your accountsection of the
Installationpage and enter appropriate Admin login details:
Name: <admin name> User: <admin username> Password: <admin password> Email: <admin email>
When you have checked that all of the installation details are correct, simply click on
Installto 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:
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
