1. Setup MySQL

Install the MySQL database server.

dnf install mysql-server

Start MySQL.

systemctl start mysqld

Create a new ICTCRM database.


Create a database user and assign a secure password.

CREATE USER ‘suite’@’localhost’ IDENTIFIED BY ‘secure-password’;
Grant the user full permissions to the ICTCRM database.
GRANT ALL ON suitecrm.* TO ‘suite’@’localhost’;

2. Setup PHP

Enable the PowerTools repository

dnf config-manager –set-enabled powertools

Install the Extra Packages for Enterprise Linux (EPEL) repository.

dnf install epel-release

Install the Remi repository.

dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm -y

Install PHP Version 7.4.

dnf module install php:remi-7.4

Install required PHP modules.

dnf install php php-fpm php-mysqlnd php-cgi php-bcmath php-json php-xml php-gettext php-common php-curl php-intl php-zip php-imap php-pear php-mbstring php-gd -y

Edit the main PHP configuration file.

vim /etc/php.ini

Locate the upload_max_filesize = 2M directive near line 846, and change its value to 20MB or above as required by ICTCRM.

upload_max_filesize = 20M

Save and close the file.

Restart PHP-FPM to load changes.

systemctl restart php-fpm

3. Setup ICTCRM

rm -rf /var/www/html/
wget https://github.com/ictinnovations/ictcrm/archive/refs/heads/ictcrm-7.13.zip

Unzip the downloaded release file.

unzip ictcrm-7.13.zip

Move extracted files to the ICTCRM webroot directory.

mv ictcrm-ictcrm-7.13/ /var/www/html

Grant apache ownership permissions on the ICTCRM directory.

chown -R apache:apache /var/www/html

Set the directory permissions mode temporarily to 777 for ICTCRM to write new files.

chmod -R 755 /var/www/html

Restart apache.

systemctl restart httpd

Disable firewall and SElinux

service firewalld stop
setenforce 0

Create custom folder and config_override.php file

mkdir /var/www/html/custom
touch /var/www/html/config_override.php

Change the permissions

chmod -R 777 cache custom modules themes data upload config_override.php

Access the ictcrm from browser via hostname / server ip and complete the installation

4. Json APIs

Before you start calling endpoints, Please ensure that you have the following:

  1. OpenSSL PHP Extension installed and configured
  • To add the CentOS 8 EPEL repository, run the following command:
dnf install epel-release
  • Now that you have access to the repository, install all of the required packages:
dnf install certbot python3-certbot-apache mod_ssl
  1. The ICTCRM instance must be configured to use HTTPS/SSL
  • Add VirtualHost in httpd.conf file
vi /etc/httpd/conf/httpd.conf
  • then add following lines in httpd.conf file
<VirtualHost *:80>
DocumentRoot “/usr/ictbroadcast/wwwroot”
ServerName voip.baystreetcapitalventures.com

change the document root to “/var/www/html” and set your server name

  • restart Apache service

Now that Certbot is installed, you can use it to request an SSL certificate for your domain.

certbot –apache
  1. Update your host & URL from “vi /var/www/html/config.php” file


Install composer package with

composer install

Generate Private and Public.key for OAUTH2

ICTCRM Api uses OAuth2 protocol, which needs public and private keys.

First, open a terminal and go to {{ictcrm.root}}/Api/V8/OAuth2

Generate a private key:

openssl genrsa -out private.key 2048

then a public key:

openssl rsa -in private.key -pubout -out public.key

The permission of the key files must be 600 or 660, so change it.

sudo chmod 600 private.key public.key

Also, you have to be sure that the config files are owned by PHP.

sudo chown www-data:www-data p*.key

replace the www-data:www-data with your user for example if you are using apache then replace it with apache.

OAUTH2 encryption key

OAuth2’s AuthorizationServer needs to set an encryption key for security reasons. This key has been generated during the ICTCRM installation and stored in the config.php under “oauth2_encryption_key”. If you would like to change its value you may generate a new one by running

php -r ‘echo base64_encode(random_bytes(32)), PHP_EOL;

and then store the output in the config.php

Sample code for API Testing:

$ch = curl_init();
$header = array(
    'Content-type: application/vnd.api+json',
    'Accept: application/vnd.api+json',
$postStr = json_encode(array(
    'grant_type' => 'password',
 'client_id' => 'e5f33999-e1b0-2339-58af-63f5d0f697dd',
    'client_secret' => 'admin',
    'username' => 'admin',
    'password' => 'admin',
$url = 'https://suit.ictcrm.com/Api/access_token';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postStr);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$output = curl_exec($ch);
