How to Install LimeSurvey CE on FreeBSD 12

LimeSurvey is an open source survey software written in PHP. LimeSurvey source code is hosted on GitHub. This guide will show you how to install LimeSurvey Community Edition (CE) on a fresh FreeBSD 12 Vultr instance.

Requirements

• Minimum 180 MB disk space
• Nginx version 1.1 or greater
• PHP 7.0.0 or greater is recommended, with the following modules and libraries enabled:
  • MBstring, PDO database driver for MySQL or PostgreSQL, GD-Library, IMAP, LDAP, ZIP
• MySQL version 5.5.3 or greater

Before you begin

Check the FreeBSD version.

uname -ro
# FreeBSD 12.0-RELEASE

Ensure that your FreeBSD system is up to date.

freebsd-update fetch install
pkg update && pkg upgrade -y

Install the necessary packages.

pkg install -y sudo vim unzip curl wget bash socat git

Create a new user account with your preferred username. We will use johndoe.

adduser

# Username: johndoe
# Full name: John Doe
# Uid (Leave empty for default): <Enter>
# Login group [johndoe]: <Enter>
# Login group is johndoe. Invite johndoe into other groups? []: wheel
# Login class [default]: <Enter>
# Shell (sh csh tcsh nologin) [sh]: bash
# Home directory [/home/johndoe]: <Enter>
# Home directory permissions (Leave empty for default): <Enter>
# Use password-based authentication? [yes]: <Enter>
# Use an empty password? (yes/no) [no]: <Enter>

# Add another user? (yes/no): no
# Goodbye!

Run the visudo command and uncomment the %wheel ALL=(ALL) ALL line, to allow members of the wheel group to execute any command.

visudo

# Uncomment by removing hash (#) sign
# %wheel ALL=(ALL) ALL

Now, switch to your newly created user with su.

su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

sudo tzsetup

Soft-link php.ini-production to php.ini.

sudo ln -s /usr/local/etc/php.ini-production /usr/local/etc/php.ini

Enable and start PHP-FPM.

sudo sysrc php_fpm_enable=yes
sudo service php-fpm start

Install MariaDB

sudo pkg install -y mariadb102-client mariadb102-server

Check the version.

mysql --version
# mysql  Ver 15.1 Distrib 10.2.25-MariaDB, for FreeBSD12.0 (amd64) using readline 5.1

Start and enable MariaDB.

sudo sysrc mysql_enable="yes" 
sudo service mysql-server start

Run the mysql_secure_installation script to improve the security of your MariaDB installation.

sudo mysql_secure_installation

Log into MariaDB as the root user.

mysql -u root -p
# Enter password:

Create a new MariaDB database and user. Remember the credentials for this new user.

CREATE DATABASE dbname;
GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit;

Install and configure Nginx

Install Nginx.

sudo pkg install -y nginx

Check the version.

nginx -v
# nginx version: nginx/1.16.0

Enable and start Nginx.

sudo sysrc nginx_enable=yes
sudo service nginx start

Run sudo vim /usr/local/etc/nginx/limesurvey.conf and set up Nginx for LimeSurvey.

server {
  listen 80;
  listen [::]:80;

  server_name example.com;

  root /usr/local/www/limesurvey;

  index index.php index.html;

  location / {
    try_files $uri $uri/ /index.php?$query_string;
  }

  location ~ /.php$ {
    fastcgi_index index.php;
    try_files $uri =404;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass 127.0.0.1:9000;
  }
}

Save the file and exit.

Now we need to include limesurvey.conf in the main nginx.conf file.

Run sudo vim /usr/local/etc/nginx/nginx.conf and add the following line to the http {} block.

include limesurvey.conf;

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo service nginx reload
