Requirements for On-premises builder installation On-Premises

Apache 2.2 (or newer) / LiteSpeed / Nginx
Required Apache modules: rewrite, headers
PHP 7.1 (or newer)
Required extensions: gd (version 2+), exif, sqlite, pdo, pdo_mysql, pdo_sqlite, json, curl, mbstring, iconv, xml, fileinfo, openssl, zlib, zip, ssh2 (only if using publication via SSH)
Important: Make sure PHP xdebug extension is disabled.
MySQL 5.5 (or newer) / MariaDB 5.5 (or newer)
ionCube Loader (newest version possible) ionCube install instructions can be found at ionCube site: http://www.ioncube.com/loaders.php
The recommended way of installing ionCube loader is by downloading loader wizard loader-wizard.zip, extracting it to web-servers document root and opening it via browser and then just following install instructions from there.
Web accessibility through domain (sub-domain). Local builder installations are not supported. Make sure that you specified correct domain (sub-domain) for builder. It must be accessible publicly on the WEB.
Hardware:
CPU: 2GHz
RAM: 2048MB
Storage (HDD or SSD): 20 GB (it can vary depending on number of customers using site builder) (see how the space can be optimized).
(This is recommended hardware requirements, depending on concurrent user count you might be OK with half or even less)
Operating system (OS):
Ubuntu / Debian / CentOS / Windows (should work on any other operating system)
recommended Review requirements for a collaboration service

Builder can also be installed on a hosting control panel like cPanel, Plesk, DirectAdmin and other on an existing or new account.

Notes for CentOS owners:

You will possibly need to enable curl, sockets, ... (network access) for web server. This can be done by executing command: setsebool -P httpd_can_network_connect on
If ionCube is not working there might be problems with SELinux permissions. To fix that execute command: ls -alZ /usr/lib64/php/modules/ to list all php modules (command part /usr/lib64/php/modules/ is a path where you installed ionCube loader, so you need to set it to where you installed it), and check if ionCube loader SELinux context matches other php modules, if not, set it to match using this command:
chcon system_u:object_r:lib_t:s0 /usr/lib64/php/modules/ioncube_loader_lin_5.3.so (command part system_u:object_r:lib_t:s0 is the context string, so you need to change it to match other php modules).

Nginx if used instead of Apache

Configuration for builder: On-Premises

If you want to use NGINX Web Server instead of Apache for builder installation you will need to configure separate virtual host (server configuration) for it. Ex. if your builder domain is some.builder.domain and builder is installed at /home/builder/public_html you could set server configuration to something like this:

listen       80;
server_name  some.builder.domain;

charset utf-8;
root /home/builder/public_html;

index  index.php;

location ~ /(\.ht|error_log|php_errors\.log|config\.json|config\.json\.backup)|^/(vendor/|src/) {
	deny  all;
}

location ~ \.php$ {
	fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
	fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
	include        fastcgi_params;
}

location ~ "^((?:/v3|)/data/[^/]+/[^/]+/(?:[^/]+/)?(?:out|preview|preview_[0-9a-zA-Z]+|tmp/[0-9a-f]{32})/)(.*)$" {
	try_files $uri $uri/ $1/sitepro/$2 $1/sitepro/$2/ $1/sitepro/index.php?$args;
}

# For installer config test.
location /installer/rewrite_test/ { return 200 'OK'; }

location /v3/ {
	try_files $uri $uri/ /v3/index.php?$args;
}

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