How to build Apache service in Linux system
The Apache service is an open source, cross-platform Web server software, and its role is to provide web content to the user's Web browser. Specifically, the Apache service has the following main functions:
1. Web server : Apache is a powerful and widely used web server software. It can receive and respond to HTTP requests from the user's browser, send the requested webpage or other resources to the browser, and realize website access and data transmission.
2. Static file service : Apache can be used to host and serve various static files, such as HTML pages, images, CSS style sheets, JavaScript scripts, etc. It can return the corresponding files according to the user's request, so that the user can access these files through the browser.
3. Dynamic content processing : In addition to static files, Apache also supports processing dynamic content. By combining with other programming languages and technologies (such as PHP, Python, Ruby, and CGI, etc.), Apache can execute server-side scripts and programs, and return the results to the client browser. This way, websites can generate dynamic, personalized content based on user requests.
4. Virtual host support : Apache supports virtual hosts, that is, running multiple different websites on the same physical server. By configuring different virtual hosts, each website can have an independent domain name, directory structure and settings, enabling simultaneous hosting of multiple websites, thereby providing better flexibility and resource utilization.
5. Security and authentication : Apache provides some security features, such as SSL/TLS encryption protocol and password-based authentication to ensure the security of transmitted data. In addition, Apache also supports access control lists (ACL) and other security mechanisms to help users protect Web servers from malicious attacks and illegal access.
In short, the Apache service plays a key role in the Internet. It is a bridge connecting web browsers and web applications, providing users with efficient and reliable web content transmission and access experience.
It is very simple to build Apache service in Linux (CentOS 7) system. Here's a step-by-step guide:
Step 1: Update your system Before starting, make sure your system is updated to the latest version. Open a terminal and run the following command as administrator:
sudo yum update
This will update the system and install any available packages
Step 2: Install Apache Next, install the Apache web server with the following command:
sudo yum install httpd
When the system prompts you whether you want to install the relevant dependencies, press the "y" key to continue the installation
Step 3: Start Apache Once the installation is complete, start the Apache service with the following command:
sudo systemctl start httpd
Step 4: Set up automatic start at boot In order to automatically start the Apache service when the system starts, run the following command:
sudo systemctl enable httpd
Now, every time the system is rebooted, the Apache service will start automatically.
Step 5: Configure Firewall If your system has a firewall enabled (e.g. firewalld), you need to allow HTTP traffic through. Run the following command:
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload
This way, the firewall will allow HTTP requests through
Step 6: Deploy the website Now, you can deploy your website files to Apache's default document root directory /var/www/html/. It can be tested with the following command:
sudo cp /path/to/your/website/* /var/www/html/
Replace /path/to/your/website/with your actual website file path
Step 7: Test the website After the deployment is complete, open a browser and enter the server's IP address or domain name. If you see your website content displayed in the browser, congratulations, you have successfully built the Apache service and deployed the website on the Linux system.
Now, you can further configure and optimize your website according to your needs, such as setting up virtual hosting, enabling SSL, etc.
