I will show you through the step-by-step installation of LimeSurvey on an Ubuntu 18.04 (Bionic Beaver) server.

Install LimeSurvey on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also, install all required PHP modules:

apt-get install php7.1-cli php7.1-mbstring php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Installing LimeSurvey on Ubuntu 18.04.

Download the latest stable version of LimeSurvey, At the moment of writing this article it is version 3.15.6:

wget https://www.limesurvey.org/stable-release?download=2519:limesurvey3156%20190108zip
unzip "stable-release?download=2519:limesurvey3156 20190108zip"
mv limesurvey/ /var/www/html/limesurvey/

We will need to change some folders permissions:

chown www-data:www-data -R /var/www/html/limesurvey
chmod -R 755 /var/www/html/limesurvey/

Step 4. Configuring MariaDB.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for the LimeSurvey. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for LimeSurvey installation:

CREATE DATABASE limesurvey;
GRANT ALL PRIVILEGES ON limesurvey.* TO 'limeuser'@'localhost' IDENTIFIED BY 'your-password';
FLUSH PRIVILEGES;
\q

Step 5. Configuring Apache web server for LimeSurvey.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘limesurvey.conf’ on your virtual server:

touch /etc/apache2/sites-available/limesurvey.conf
ln -s /etc/apache2/sites-available/limesurvey.conf /etc/apache2/sites-enabled/limesurvey.conf
nano /etc/apache2/sites-available/limesurvey.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin admin@yourdomain.com
DocumentRoot /var/www/html/limesurvey/
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/limesurvey/>
Options FollowSymLinks
AllowOverride All
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Now, we can restart the Apache web server so that the changes take place:

sudo a2ensite limesurvey.conf
sudo a2enmod rewrite
sudo systemctl restart apache2.service

Step 6. Accessing the LimeSurvey Web Interface.

LimeSurvey will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/admin or http://server-ip-addreess/admin and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
