How to Set up LimeSurvey (CE) on CentOS 7

LimeSurvey is an free study application published in PHP. LimeSurvey resource rule is organised on GitHub. In this guide, we will take you step-by-step through the LimeSurvey Community Version (CE) set up procedure on a clean CentOS 7 program.


In to set up LimeSurvey (CE) on your CentOS 7 program, make sure your program satisfies the following requirements:

  • Minimum 250 MB hard drive area.
  • MySQL 5.5.3 or later or MariaDB 5.5 or later. This guide will use MariaDB.
  • PHP 5.5.9 or later (PHP 7.0.0+ is recommended) with the following extensions: Mbstring, PDO data resource car owner for MySQL or PostgreSQL, GD-Library, IMAP, LDAP, ZIP.
  • Apache 2.4 or later or Nginx 1.1 or later. This guide will use Nginx.

Initial steps

Check your CentOS program version:

cat /etc/centos-release
# CentOS Linux system launch 7.5.1804 (Core)

Set up the timezone:

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Update your working system’s packages:

sudo yum upgrade -y

Install vim, git, unzip, and socat packages:

sudo yum set up -y vim git unzip socat

Step 1 – Install PHP

LimeSurvey needs PHP edition 5.5.9 or higher, while PHP 7.0.0+ is the suggested edition. Standard CentOS databases contain mature edition of PHP, and thus we will need to set up a third-party database to use a more recent PHP edition. We will use Webtatic database.

Setup the Webtatic YUM repo:

sudo rpm -Uvh

Install PHP, as well as the necessary PHP extensions:

sudo yum set up -y php72w php72w-cli php72w-fpm php72w-common php72w-mbstring php72w-xml php72w-mysql php72w-gd php72w-zip php72w-ldap php72w-imap

Check the PHP version:

php --version

# PHP 7.2.12 (cli) (built: Nov 11 2018 14:54:16) ( NTS )
# Trademark (c) 1997-2018 The PHP Group
# Zend Motor v3.2.0, Trademark (c) 1998-2018 Zend Technologies

Start and allow PHP-FPM service:

sudo systemctl begin php-fpm.service
sudo systemctl allow php-fpm.service

Step 2 – Install MariaDB and build a data resource for LimeSurvey

Install MariaDB data resource server:

sudo yum set up -y mariadb-server

Check the MariaDB version:

mysql --version
# mysql Ver 15.1 Distrib 5.5.60-MariaDB, for Linux system (x86_64) using readline 5.1

Start and allow MariaDB service:

sudo systemctl begin mariadb.service
sudo systemctl allow mariadb.service

Run mysql_secure installation script to enhance MariaDB protection and set the protection password for MariaDB root user:

sudo mysql_secure_installation

Answer the concerns as proven below:

Enter present protection password for main (enter for none):
Set main password? [Y/n]: Y
Remove unknown users? [Y/n]: Y
Disallow main sign in remotely? [Y/n]: Y
Remove analyze data resource and accessibility to it? [Y/n]: Y
Reload benefit platforms now? [Y/n]: Y

Log into MariaDB spend as the customer root:

mysql -u main -p
# Get into password

Create a MariaDB data resource and customer that you will use for your set up of LimeSurvey, don’t forget the credentials:

GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';

Exit from MariaDB shell:


Step 3 – Install and set up Nginx

Install Nginx webserver:

sudo yum set up -y nginx

Check the NGINX version:

nginx -v
# nginx version: nginx/1.12.2

Start and allow Nginx service:

sudo systemctl begin nginx.service
sudo systemctl allow nginx.service

Run sudo vim /etc/nginx/conf.d/limesurvey.conf and fill the computer file with the following configuration:

server {
 pay attention 80;

 main /var/www/limesurvey;

 catalog index.php;

 place / {
 try_files $uri $uri/ /index.php?$args;
 place ~ .php$ {
 try_files $uri =404;
 consist of fastcgi_params;
 fastcgi_index catalog.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;


Test the NGINX configurations.

sudo nginx -t

Reload NGINX.

sudo systemctl refill nginx.service

Step 4 – Obtain and set up LimeSuervey

Create a papers main directory:

sudo mkdir -p /var/www/limesurvey

Change possession of the /var/www/limesurvey directory to johndoe:

sudo chown -R [your_user]:[your_user] /var/www/limesurvey

Navigate to papers root:

cd /var/www/limesurvey

Download the LimeSurvey ZIP installer:

wget -O

Unzip LimeSurvey installer:

mv limesurvey/* . && mv limesurvey/.* .
rmdir limesurvey

Change possession of the /var/www/limesurvey directory to nginx:

sudo chown -R nginx:nginx /var/www/limesurvey

Create the directory/var/lib/php/session and set possession to nginx.

sudo mkdir -p /var/lib/php/session && sudo chown -R nginx:nginx /var/lib/php

Run sudo vim /etc/php-fpm.d/www.conf and set the customer and team to nginx. Originally, they will be set to apache:

sudo vim /etc/php-fpm.d/www.conf
# customer = nginx
# team = nginx

Restart the PHP-FPM service:

sudo systemctl reboot php-fpm.service
