Vanilla is free, open source discussion forum written in PHP. Vanilla Forum software is distributed under the GNU GPL2 license. Its source code is available through Github. It has a rich add-on system that you can take advantage of to add custom features to your Vanilla forum. Content for Vanilla Forum can be written using the Markdown language. In this tutorial, we will go through the Vanilla Forum installation and setup on CentOS 7 system by using Nginx as a web server, MySQL as a database server, and optionally you can secure transport layer by using client and Let's Encrypt certificate authority to add SSL support. 


Vanilla requires a server with PHP, MySQL, and web server software (like Apache or Nginx). You'll probably need to own a domain, and already have it configured on your server with DNS if you want to install on a production server, but if not then you don't need a domain.

Vanilla Forum minimum requirements are:

  • PHP version 7.0 or newer.
  • PHP extensions mbstring, cURL, GD, and PDO, MySQLi, OpenSSL.
  • MySQL version 5.0 or newer (or Percona/MariaDB equivalent).
  • Web Server software (Nginx, Apache ...).
  • MySQL strict mode disabled.

Vanilla Forum strongly recommends:

  • PHP version 7.2 or newer.
  • PHP extensions mbstring, cURL, GD, and PDO, MySQLi, OpenSSL.
  • MySQL version 5.7 or newer (or Percona/MariaDB equivalent).
  • Web server software (Nginx, Apache ...).
  • SSL encryption.

NOTEPHP 7.0 has reached end of life and will no longer receive security patches, so it's highly recommended to use newer PHP versions. Vanilla's support for PHP 7.0 will end soon!


  • An operating system running CentOS 7.
  • A non-root user with sudo privileges.

Initial steps

Check your CentOS version:

cat /etc/centos-release
# CentOS Linux release 7.6.1810 (Core)

Set up the timezone:

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

Update your operating system packages (software). This is an important first step because it ensures you have the latest updates and security fixes for your operating system's default software packages:

sudo yum update -y

Install some essential packages that are necessary for basic administration of the CentOS operating system:

sudo yum install -y curl wget vim git unzip socat bash-completion epel-release

Step 1 - Install PHP and necessary PHP extensions

Setup the Webtatic YUM repo:

sudo rpm -Uvh

Install PHP, as well as the necessary PHP extensions:

sudo yum install -y php72w php72w-cli php72w-fpm php72w-common php72w-mbstring php72w-curl php72w-gd php72w-mysql

To show PHP compiled in modules, you can run:

php -m

. . .
. . .

Check PHP version:

php --version

# PHP 7.2.14 (cli) (built: Jan 12 2019 12:47:33) ( NTS )
# Copyright (c) 1997-2018 The PHP Group
# Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

Start and enable PHP-FPM service:

sudo systemctl start php-fpm.service
sudo systemctl enable php-fpm.service

We can move on to the next step, which is database installation and setup.

Step 2 - Install MariaDB and create a database for Vanilla Forum

Vanilla Forum supports MySQL, MariaDB and Percona databases. In this tutorial, we will use MariaDB as database server. Since default CentOS 7 repositories contain very old MariaDB version that is not compatible with Vanilla Forum, we will need to use the official MariaDB repo to install a newer version.

Create MariaDB 10.2 YUM repository for CentOS:

sudo vim /etc/yum.repos.d/MariaDB.repo

Copy and paste the following text into it:

# MariaDB 10.2 CentOS repository list - created 2017-12-11 23:19 UTC

After the file is in place, install MariaDB by running:

sudo yum install -y MariaDB-server MariaDB-client

Check the MariaDB version:

mysql --version
# mysql  Ver 15.1 Distrib 10.2.21-MariaDB, for Linux (x86_64) using readline 5.1

Start and enable MariaDB service:

sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Run mysql_secure installation script to improve MariaDB security and set the password for MariaDB root user:

sudo mysql_secure_installation

Answer each of the questions:

Enter current password for root (enter for none): Press Enter
Set root password? [Y/n] Y
New password: your_secure_password
Re-enter new password: your_secure_password
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

Connect to MariaDB shell as the root user:

sudo mysql -u root -p
# Enter password

Create an empty MariaDB database and user for Vanilla Forum and remember the credentials:

MariaDB [(none)]> CREATE DATABASE dbname;
MariaDB [(none)]> GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';

Exit from MariaDB:

MariaDB [(none)]> exit

Replace dbnameusername and password with your own names.

Step 3 - Install client and obtain Let's Encrypt certificate (optional)

Securing your website with HTTPS is not necessary, but it is a good practice to secure your site traffic. In order to obtain TLS certificate from Let's Encrypt we will use client. is a pure unix shell software for obtaining TLS certificates from Let's Encrypt with zero dependencies. 

Download and install

sudo su - root
git clone
./ --install --accountemail
source ~/.bashrc
cd ~

Check version: --version
# v2.8.0

Obtain RSA and ECC/ECDSA certificates for your domain/hostname:

# RSA 2048 --issue --standalone -d --keylength 2048
# ECDSA --issue --standalone -d --keylength ec-256

If you want fake certificates for testing you can add --staging flage to the above commands.

After running the above commands, your certificates and keys will be in:

  • For RSA/home/username/ directory.
  • For ECC/ECDSA/home/username/example.com_ecc directory.

To list your issued certs you can run: --list

Create a directories to store your certs. We will use /etc/letsencrypt directory.

mkdir -p /etc/letsecnrypt/
sudo mkdir -p /etc/letsencrypt/example.com_ecc

Install/copy certificates to /etc/letsencrypt directory.

# RSA --install-cert -d --cert-file /etc/letsencrypt/ --key-file /etc/letsencrypt/ --fullchain-file /etc/letsencrypt/ --reloadcmd "sudo systemctl reload nginx.service"
# ECC/ECDSA --install-cert -d --ecc --cert-file /etc/letsencrypt/example.com_ecc/cert.pem --key-file /etc/letsencrypt/example.com_ecc/private.key --fullchain-file /etc/letsencrypt/example.com_ecc/fullchain.pem --reloadcmd "sudo systemctl reload nginx.service"

All the certificates will be automatically renewed every 60 days.

After obtaining certs exit form root user and return back to normal sudo user:


Step 4 - Install NGINX and configure NGINX for Vanilla Forum

Vanilla Forum can work fine with many popular web server software. In this tutorial, we selected Nginx. If you prefer Apache web server over Nginx, please visit to learn more.

Download and install Nginx from the CentOS repository:

sudo yum install -y nginx

Check the Nginx version:

nginx -v
# nginx version: nginx/1.12.2

Start and enable Nginx service:

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Configure Nginx for Vanilla by running:

sudo vim /etc/nginx/conf.d/vanilla.conf

And populate the file with the following configuration:

server {

listen 80;
listen 443 ssl http2;
root /var/www/vanilla;
index index.php;

ssl_certificate /etc/letsencrypt/;
ssl_certificate_key /etc/letsencrypt/;
ssl_certificate /etc/letsencrypt/example.com_ecc/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/example.com_ecc/private.key;

location ~* /\.git { deny all; return 403; }
location /build/ { deny all; return 403; }
location /cache/ { deny all; return 403; }
location /cgi-bin/ { deny all; return 403; }
location /uploads/import/ { deny all; return 403; }
location /conf/ { deny all; return 403; }
location /tests/ { deny all; return 403; }
location /vendor/ { deny all; return 403; }

location ~* ^/index\.php(/|$) {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
try_files $fastcgi_script_name =404;
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_param SCRIPT_NAME /index.php;
fastcgi_param SCRIPT_FILENAME $realpath_root/index.php;
fastcgi_param X_REWRITE 1;

location ~* \.php(/|$) {
rewrite ^ /index.php$uri last;

location / {
try_files $uri $uri/ @vanilla;

location @vanilla {
rewrite ^ /index.php$uri last;


NOTEFor complete and production ready Nginx config for Vanilla visit

Check Nginx configuration for syntax errors:

sudo nginx -t

Reload Nginx service:

sudo systemctl reload nginx.service

Step 5 - Install Vanilla Forum

Create a document root directory where Vanilla Forum should reside in:

sudo mkdir -p /var/www/vanilla

Change ownership of the /var/www/vanilla directory to {jour_user}:

sudo chown -R {your_user}:{your_user} /var/www/vanilla

NOTEReplace {jour_user} with your initially created non-root user username.

Navigate to the document root directory:

cd /var/www/vanilla

Download the Vanilla Forum zip archive:


Extract and remove Vanilla zip archive:


Provide the appropriate ownership:

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

Run sudo vim /etc/php-fpm.d/www.conf and set the user and group to nginx. Initially, they will be set to apache:

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx

Navigate to the folder where you uploaded Vanilla in your web browser and follow the instructions on the screen.

Step 6 - Complete the Vanilla Forum Installation and Setup

After opening your site in a web browser, you should be redirected.

Fill in the required information and click on the "Continue →" button to finish up the installation and setup. After that Vanilla Forum admin interface should appear.
