This brief tutorial shows students and new users how to install and configure the YetiForce CRM platform on Ubuntu 18.04 | 16.04 with Nginx HTTP servers.
Our previous tutorial showed you how to install YetiForce CRM on Ubuntu with an Apache2 HTTP server. This one shows you how to use Nginx instead.
For the uninitiated, YetiForce is an open-source Customer Relationship Management (CRM) software forked from Vtiger CRM that can serve as a strong alternative to the popular CRM systems in use today.
If you currently run the Vtiger CRM platform and feel like it’s lacking in some areas, you might want to try YetiForce. It comes with intuitive mechanisms that allow you to easily migrate from Vtiger to YetiForce.
For more about YetiForce, please check its homepage.
To get started with installing YetiForce, follow the steps below:
Install Nginx HTTP Server
YetiForce requires a web server and the Nginx HTTP server is probably the second most popular open-source web server available today.
To install the Nginx server, run the commands below:
sudo apt update sudo apt install nginx
After installing Nginx, the commands below can be used to stop, start and enable the Nginx service to always start up with the server boots.
sudo systemctl stop nginx.service sudo systemctl start nginx.service sudo systemctl enable nginx.service
Now that Nginx is installed, open your browser and browse to the URL below to test whether the web server is working.
http://localhost

If you see the page above, then Nginx is successfully installed.
Install MariaDB Database Server
YetiForce also requires a database server to store its content. MariaDB is a great place to start if you’re looking for a truly open-source database server.
To install MariaDB run the commands below:
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can stop, start and enable the MariaDB service to start up when the server boots.
Run these on Ubuntu 16.04 LTS
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Run these on Ubuntu 18.10 and 18.04 LTS
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Press the Enter
- Set root password? [Y/n]: Y
- New password: Enter the password
- Re-enter new password: Repeat 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
Once MariaDB is installed, run the commands below to test whether the database server was successfully installed.
sudo mysql -u root -p
type the root password when prompted.

The server was successfully installed if you see a similar screen as shown above.
Install PHP 7.2-FPM and Related Modules
YetiForce is a PHP-based platform and for now, only PHP 7.2-FPM. PHP 7.2-FPM may not be available in Ubuntu default repositories. To run PHP 7.2-FPM on Ubuntu 14.04, you may need to run the commands below:
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2-FPM
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2-fpm php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-bcmath php7.2-soap php7.2-ldap php7.2-imap php7.2-xml php7.2-cli php7.2-zip
After installing PHP 7.2, run the commands below to open Nginx’s PHP default configuration file.
sudo nano /etc/php/7.2/fpm/php.ini
The lines below are a good setting for most PHP-based CMS. Update the configuration file with these and save.
file_uploads = On allow_url_fopen = On short_open_tag = On cgi.fix_pathinfo = 0 memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
You should restart the Nginx web server whenever you make changes to the PHP configuration file. To do so, run the commands below:
sudo systemctl restart nginx.service
Once PHP is installed, create a test file called phpinfo.php in the Nginx default root directory. ( /var/www/html/)
sudo nano /var/www/html/phpinfo.php
Then type the content below and save the file.
<?php phpinfo( ); ?>
Next, open your browser and browse to the server’s hostname or IP address followed by phpinfo.php
http://localhost/phpinfo.php
You should see the PHP default test page.

Create YetiForce Database
Now that you’ve installed all the packages required for YetiForce to function, continue below to start configuring the servers. First, run the commands below to create a blank YetiForce database.
To log on to the MariaDB database server, run the commands below.
sudo mysql -u root -p
Then create a database called yetiforce
CREATE DATABASE yetiforce;
Create a database user called yetiforceuser with a new password
CREATE USER 'yetiforceuser'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON yetiforce.* TO 'yetiforceuser'@'localhost' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Download YetiForce Latest Release
YetiForce community edition can be downloaded from its download page here.
On the Ubuntu terminal, run the commands below to download, then extract to its root directory.
cd /tmp wget https://excellmedia.dl.sourceforge.net/project/yetiforce/YetiForce%20CRM%205.x.x/5.1.0/YetiForceCRM-5.1.0-complete.zip sudo mkdir /var/www/yetiforce sudo unzip YetiForceCRM-5.1.0-complete.zip -d /var/www/yetiforce
Then run the commands below to set the correct permissions for the YetiForce root directory and give Nginx control.
sudo chown -R www-data:www-data /var/www/yetiforce/ sudo chmod -R 755 /var/www/yetiforce/
Configure Nginx
Finally, configure the Apahce2 site configuration file for YetiForce. This file will control how users access YetiForce content. Run the commands below to create a new configuration file called yetiforce
sudo nano /etc/nginx/sites-available/yetiforce
Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and directory root location.
server {
listen 80;
listen [::]:80;
server_name example.com www.example.com;
root /var/www/yetiforce;
index index.php;
access_log /var/log/nginx/example.com.access.log;
error_log /var/log/nginx/example.com.error.log;
client_max_body_size 100M;
autoindex off;
location / {
index index.html index.php;
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
include fastcgi_params;
fastcgi_intercept_errors on;
}
}
Save the file and exit.
Enable the YetiForce and Rewrite Module
After configuring the VirtualHost above, enable it by running the commands below
sudo ln -s /etc/nginx/sites-available/yetiforce /etc/nginx/sites-enabled/ sudo systemctl restart nginx.service
Then open your browser and browse to the server domain name. You should see the YetiForce setup wizard complete. Please follow the wizard carefully.
http://example.com/
Then follow the on-screen instruction to complete the setup

Next, type in the database name, username, and password. then create a backend admin account and continue.

The YetiForce system has strictly defined requirements for the server on which it will be installed. The verification of requirements at an early stage of the installation process ensures that the next steps and subsequent use of the system will run without problems.

Enter your company details and continue

After that, your environment should be installed and ready to use.

It seems that the permissions für the path on the server, where yetiforce files where extracted or uploaded.
In the example abouve we have:
sudo chown -R www-data:www-data /var/www/yetiforce/
sudo chmod -R 755 /var/www/yetiforce/
If you moved or extracted the files on into /var/www/html/ than you need to change it here as well and try to run this command, than restart nginx and refresh your page in your browser
sudo chown -R www-data:www-data /var/www/html/
sudo chmod -R 755 /var/www/html/
