ImpressPages CMS 5.0 is a simple and effective, free and open source, user-friendly, MVC-based, Content Management System (CMS). ImpressPages CMS 5.0 features: inline editing with a drag and drop interface, lightweight and clean MVC routing, template helpers, URL generation, and is multi-lingual by default.
In this tutorial we are going to install ImpressPages CMS 5.0 on a CentOS 7 LAMP VPS using Apache web server, PHP 7.1, and a MariaDB database.
- A clean IT Web Services CentOS 7 server instance with SSH access.
Step 1: Add a Sudo User
We will start by adding a new
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 should 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. 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:
Step 2: Update CentOS 7 System
We will update the system before installing any packages on the CentOS server instance.
Make sure you are logged into 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 should 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 “
mod_rewrite“. Open the file:
sudo vi /etc/httpd/conf.modules.d/00-base.conf
Search for the term
mod_rewrite Apache module is loaded, you should 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 ImpressPages 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) should 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:
If everything has been set up correctly, 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 finer 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 ImpressPages CMS we need to ensure that SELinux is disabled.
Check whether or not SELinux is enabled 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 favorite 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 be 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. Run the following command:
sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
We can now install the latest version of PHP 7.1 along with the necessary PHP modules required by ImpressPages 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 the MariaDB database server, which is an enhanced, 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 ImpressPages 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 ImpressPages CMS.
CREATE DATABASE impress_db CHARACTER SET utf8 COLLATE utf8_general_ci; CREATE USER 'impress_db'@'localhost' IDENTIFIED BY 'UltraSecurePassword'; GRANT ALL PRIVILEGES ON impress_db.* TO 'impress_db'@'localhost'; FLUSH PRIVILEGES; EXIT;
You can replace the database name
impress_db and username
impress_db 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 actual secure password.
Step 9: Install ImpressPages 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 should now be:
/var/www/html/. You can check this with the
pwd (print working directory) command:
wget to download the ImpressPages CMS installation package.
sudo wget http://download.impresspages.org/ImpressPages_5_0_3.zip
Please note: The above ImpressPages CMS package URL was correct at the time of writing, but you should definitely check for the most recent version by visiting the ImpressPages CMS download page.
List the current directory to check that you have successfully downloaded the file.
sudo rm index.html
Let’s quickly install
unzip so we can unzip the file.
sudo yum -y install unzip
Now uncompress the zip archive.
sudo unzip ImpressPages_5_0_3.zip
Move all of the installation files to the web root directory:
sudo mv ImpressPages/* ImpressPages/.htaccess /var/www/html
Change ownership of the web files to avoid any permissions problems.
sudo chown -R apache:apache * .htaccess
Let’s restart Apache again.
sudo systemctl restart httpd
Now we’re ready to move on to the final step.
Step 10: Complete ImpressPages CMS Installation
It’s now 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 ImpressPages 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 values on the
Website name: <name of your web site> Website e-mail address: <admin email address> Time zone: <your time zone>
Enter the following values on the
Database Host: localhost User name: impress_user User password: UltraSecurePassword Database name: impress_db
You will be redirected and logged into the Admin section of ImpressPages CMS and a message will appear displaying your admin login details, including an automatically generated password, so make sure you save your login details.
If you aren’t redirected to the admin section automatically, you can visit the following URL to access the admin section manually:
If you still can’t access the admin section, try editing some of the values in the
.htaccess file in the webroot directory:
sudo vi .htaccess
Uncommenting the following
.htaccess options should help:
Options -Indexes Options -MultiViews
… and while you’re there, it won’t hurt to uncomment these lines too:
php_value upload_max_filesize 1000M php_value post_max_size 1000M php_value memory_limit 100M
Don’t forget to restart Apache after the configuration changes!
sudo systemctl restart httpd
