This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation of LimeSurvey on a Ubuntu 16.04 (Xenial Xerus) server.
Install LimeSurvey on Ubuntu 16.04 LTS
Step 1. First, make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.
sudo apt-get update sudo apt-get upgrade
Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.
A Ubuntu 16.04 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 php7.0-curl php7.0-gd php7.0-mbstring php7.0-mysql libapache2-mod-php7.0 php7.0-mcrypt php7.0-zip
Step 3. Installing LimeSurvey.
Download the latest stable version of LimeSurvey, At the moment of writing this article it is version 2.64.1:
wget https://www.limesurvey.org/stable-release?download=2015:limesurvey2641%20170310zip unzip "stable-release?download=2015:limesurvey2641 170310zip" mv limesurvey/ /var/www/html/limesurvey/
We will need to change some folders permissions:
chown www-data:www-data -R /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.
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 firstname.lastname@example.org 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 webserver so that the changes take place:
systemctl restart apache2.service
Step 6. Accessing LimeSurvey.
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/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.
