VPSSIM: A Script To Deploy LEMP Stack Automatically In CentOS


VPSSIM, an acronym of VPS is SIMple, is an auto-installer script for LEMP stack setup. Using this script, anyone, even the novice users, can easily deploy LEMP stack, i.e Nginx, MariaDB, and PHP in minutes. VPSSIM will currently work on both CentOS 6 and CentOS 7.


  • Works both on 32 and 64bit systems;
  • Latest and stable Nginx;
  • NginX running PHP via FastCGI is faster and consumes much less RAM memory than Apache + mod_php;
  • PHP-FPM with FastCGI;
  • You can setup different versions of PHP. You can choose PHP 5.4, 5.5 or 5.6 when setup and change PHP version anytime;
  • MariaDB for better performance;
  • Supports SSL;
  • Includes PhpMyAdmin for managing databases;
  • Includes CSF firewall;
  • We can either enable or disable PhpMyAdmin;
  • Optional Zend opcache/Memcached/Google Pagespeed;
  • And many.


Before setup VPSSIM in your server, you can try VPSSIM VPS DEMO and see what it does, and how it works.

Here, We will see how to access and test VPSSIM demo.

  • VPSSIM demo IP address:
  • User name: vpssim
  • Password: vpssim

Open your Terminal, an type:

ssh vpssim@

Type ‘Yes’ to add the host ( to known list.

The authenticity of host ' (' can't be established.
RSA key fingerprint is 99:6d:40:bc:65:34:c9:e7:75:87:ea:be:39:9b:37:96.
Are you sure you want to continue connecting (yes/no)? yes

Okay, I am happy with VPSSIM, now I want to install it on my production server. How do I do it? Well, follow the procedures given below.

VPSSIM Installation

As we mentioned before, VPSSIM will work both on CentOS 6 and CentOS 7. Do not install it in a existing systems that has Nginx, Php, or MariaDB already installed. It may conflict with the existing installations. Use it only on a fresh and minimal servers.

Before setup VPSSIM, you need a VPS at minimum 512 MB RAM with centos 6 or 7. We will install and test VPSSIM in CentOS 6.5 minimal server.

Log in to your server with root privileges, and update your system.

yum update

Then, Enter the following command to start the installation.

yum -y install wget && wget https://vpssim.com/install && chmod +x install && ./install

The above command will start to pull and install all required packages. It will take a while depending upon your Internet connection speed.

After a few moments, you’ll be asked to choose which PHP version you want to install. Here, I go the latest version. So, I entered the choice 1.


Now, the installer will check for the system specifications. Then, It will ask you to enter the domain name, PHP port etc.


Now, it will ask you to confirm the details you have given. Just enter Y and hit Enter key.


Note down or take screenshot of the following URLs that needed after installation completed.

Finally press Enter.


This will take some time. The installer will start to download and install all required packages for LEMP stack. Be patient and grab a cup of Coffee!


After a few minutes, you’ll be asked to enter the MySQL root user password. Enter the password twice.


After the installation is over, your server will be automatically reboot in few seconds.

Testing Nginx:

To test whether Nginx is properly working, open up the web browser and type: http://IP-address or http://domain-name.

You should see the following nginx test page.

Access PhpMyAdmin Console:

Type http://IP-addres:2015 or http://domain-name:2015/ in the address bar of your Browser.

Enter the mysql root user name and it’s password which we created during installation. in my case my database root username/password is root/centos.
