Laravel: API-based for all types of backends

We are talking about one of the most known and used frameworks to create backends. In addition, it works with PHP language, which is very well known. Laravel offers an extensive API with excellent features. Which allows you to create web pages quickly with stable performance and easy to maintain. Some of its main features are:

• Allows you to add a secure and robust authentication system in a very simple way.
• Makes web pages much faster thanks to its internal cache.
• Allows controlling vulnerabilities and other bugs in a much easier way than with other alternatives.

Spring Web MVC: uses Java to query databases

Spring is based on the Servlet API. Therefore, it is based on Java. Moreover, it is specially designed to send requests to a database or to other servers. In addition, it allows you to configure the view resolution and take care of controlling the regional configuration of the web. Finally, it manages the theme and the file upload from the frontend. Among its main characteristics are:

• Each of the framework functions is properly separated and isolated from everything else. Thus, the controller, validator, modeler, etc. do not interfere in the operation of the others. This is possible thanks to DispatcherServlet
• It offers great configuration possibilities.
• Advanced filters that allow sending requests via GET, POST, PUT, PATCH and DELETE.
• It has a system of simulations to check that everything works correctly.

Ruby on Rails: a fast, simple and powerful framework

Ruby on Rails is another of the most popular and widely used web development frameworks. As its name suggests, it is programmed in Ruby, so it is organized in objects. Additionally, it has a very clear and light structure. You can hire Ruby on Rails developers to increase the adaptability of the program for all types of infrastructures. Some of its main features are:

• Web applications are supported by the MVC pattern.
• It requires less code than other frameworks, which allows us to create web applications in 30% to 40% less time.
• It avoids code repetition and, therefore, reduces the information inside the system and the probability of errors. This is made possible by Don’t Repeat Yourself.
• The code is fully scalable, so we can adjust it according to our needs.
• It has very secure life cycles.

ASP.NET: Microsoft’s technology for everyone.

When using .NET we are logically talking about Microsoft. This is a free, multiplatform and open source framework. Its main function is to create all kinds of web applications and services in .NET and C#. In addition, it is able to run on Windows, macOS and Linux. When running on Windows, it uses Windows Forms, WPF and UWP for creating web applications. Here are some of its main features:

• Allows programming from almost any operating system.
• Improved performance.
• Use of several versions in parallel.

In the following lines, we will continue to explore the best open source frameworks to create a website.

Cake PHP: very fast framework for creating PHP apps

This PHP framework allows users to have a very fast development. Which is essential for the creation of web applications. It also offers a fast and structured working method. And it has tools that allow to code logically all the content of the application. Let’s take a look at some of its main features:

• It allows to build a prototype very easily.
• It has an MIT license, so we can create without problems all kinds of commercial applications.
• Furthermore, it has a lot of integrated tools that allow to improve the creation of web applications. Thus, it is possible to manage translations, input validation, SQL, XSS and CSRF protection, database access and an internal cache to improve performance.

Django: The ideal framework to make things fast.

If you are short on time, this is the best framework to use. Django is based on Python. And because of its nature, it is meant to create web applications quickly with as little code as possible. The apps created with it stand out for their clean and intuitive design. Here are some features.

• It allows the creation of rich and dynamic APIs for the use of databases.
• It has a very complex authentication system based on user, groups, permissions and sessions.
• Helps development to be free of security flaws, offering protection against clickjacking, SQL injections, remote code execution and more.

In this way we have seen the best open source frameworks to create a website. We always strive to show you the best options for your benefit. Bye!

Requirements:

• Fresh minimal installation of Centos 7 without any configuration changes.
• A static IP address

Step 1. Configure Hostname

Note: hostname must be differnet from your main domain.(for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).

You can use the following command for hostname setup eg. osradar.localhost.localdomain

# hostnamectl set-hostname osradar.localhost.localdomain

# hostnamectl

Step 2. Setup Firewall

You must open following ports used by Sentora configurations in firewall so all services will run without any issue.

20 & 21 : FTP
22 SSH
25 (TCP) : SMTP
53 (TCP & UDP) : DNS
80 (TCP & UDP) : HTTP
110 : POP3
143 : IMAP
443 : HTTPS
3306: MySQL

Use below command to add ports in firewall and reload it to apply new changes.

# firewall-cmd --zone=public --permanent --add-port={20/tcp,21/tcp,22/tcp,25/tcp,53/tcp,80/tcp,110/tcp,143/tcp,443/tcp,3306/tcp}

# firewall-cmd --reload

Step 3. Installing Sentora

First install wget package using below command

# yum install wget -y

Now download installer and make it executable using below commands

# cd

# wget http://sentora.org/install

# chmod +x install

Start Sentora installation using below command

# ./install

During the installation process you will be asked to choose your geographical area and the time zone. So choose you location, set your time zone and press “Enter” to continue. In my case I will use Asia.

In the next step you will be asked to configure sub-domain, which will be used to access Sentora Panel, Secondly set the public IP of the server.

Here you might get the warning about your DNS configurations if its not properly configured then add records in your DNS manager.

Press “Y” to accept and install Senotra on your choosed subdomain with given IP. Installation can take more than 30 minutes depending on your inernet connection, because it needs to install and activate all required packages for the server.

Once the installation completeion, you will be greeted with sentora login details, copy all login details before restart (A file of login details also placed in /root/passwords.txt). Now press “Y” and ENTER key to restart the server.

Step 4. Login Sentora Control Panel.

Once server boots up, open your web browser and access your Sentora Control panel using the sub-domain or your server’s IP address and type your credentials to login.

OR

Congratulations! you have successfully installed the latest version of Sentora on CentOS 7 server. Now you can manage your multiple domains web hosting free of cost on your own hosting server.

Ngnix is a high-performance lightweight inverse web/proxy server and proxy for email protocols. It is free and open source software, licensed under the Simplified BSD License. At the same time, ngnix has a paid version, dedicated to high-performance companies and projects that require commercial support.

with this in mind, I will teach you how to configure Nginx server blocks using Ubuntu 18.04 LTS.

0. Requirements

In order to perform this tutorial satisfactorily, you should keep this in mind:

• You need to be logged in with a user with sudo enabled.
• It is recommended that you have a basic understanding of the use of the terminal.
• And obviously, need a computer with Ubuntu 18.04.

Note: The steps I will describe must also work on Linux Mint 19.

1.- Install Nginx

In the first place, you need to update the entire operating system. It’s always good to do this because it ensures you have the latest security patches installed. Open a terminal, and run:

:~$ sudo apt && sudo apt upgrade

After you enter your password, you will have the system updated.

Now, you can install ngnix. In order to reduce the time spent, install it from the package that comes in the official Ubuntu repositories. Type:

:~$ sudo apt install ngnix

Next, verify that the firewall is configured to allow nginx to operate.

:~$ sudo ufw app list

As a result, you can see the applications that are in profile in the firewall. If you see Nginx Full, Nginx HTTP and Nginx HTTPS, you are doing well.

Check the status of the service.

:~$ sudo systemctl status nginx

Go to your browser and access with the IP address of the server.

http://IP_SERVER

As can be seen, Nginx has been correctly installed.

2. Create folders for each host

For this tutorial, I will create two server blocks and consequently, a separate folder must be created for each host. Virtual hosts will be named “osradar1.test” and “osradar2.test”. Run:

:~$ sudo mkdir -p /var/www/html/osradar1.test/public_html
:~$ sudo mkdir -p /var/www/html/osradar2.test/public_html

As a result, the newly created folders belong to root. This will have negative consequences on their use. You must change the owner to your user. Type:

:~$ sudo chown -R $USER:$USER /var/www/html/osradar1.test/public_html/
:~$ sudo chown -R $USER:$USER /var/www/html/osradar2.test/public_html/

Finally, you must change the folder permissions.

3. Create an index.html file for each host

It’s time to create a test file for each host. Run:

:~$ sudo nano /var/www/html/osradar1.test/public_html/index.html

Add the following:

Now do it with the other one.

:~$ sudo nano /var/www/html/osradar2.test/public_html/index.html

It’s done.

4. Create the configuration file for each host

Then, you must create the configuration files for each Virtual hosts (block servers). In the first place, copy the Block server file by default, it will serve as a guide. Type:

:~$ sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/osradar1.test.conf
:~$ sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/osradar2.test.conf

Now proceed to edit them. You need to change two things: server name and root directives.

:~$  sudo nano /etc/nginx/sites-available/osradar1.test.conf

Now do the same for the other file. However, add a # on both “listen” lines.

:~$ sudo nano /etc/nginx/sites-available/osradar2.test.conf

That’s it. Now activate the Server Blocks.

5. Enable Nginx server blocks

Now, you can enable the new newly created server blocks. To do this, first, disable the default one:

:~$ sudo rm /etc/nginx/sites-enabled/default
:~$ sudo ln -s /etc/nginx/sites-available/osradar1.test.conf /etc/nginx/sites-enabled/
:~$ sudo ln -s /etc/nginx/sites-available/osradar2.test.conf /etc/nginx/sites-enabled/

You need to reboot the nginx service. For this reason, type.

:~ sudo systemctl restart nginx

6. Test the new server block

Now it’s time to verify that everything is correct. Edit your /etc/hosts file and add your IP and virtual hosts.

:~$ sudo nano /etc/hosts

Now go to your web browser and enter the address of the server block (virtual host) and test.

In the final analysis, I can say that nginx is a valid alternative to Apache. The way virtual hosts are created is very simple and within the reach of many.

We want to hear from you and your experience with nginx, tell us how it went?
