Deploy php in linux environment

With the rapid development of the Internet, more and more people are choosing to use Linux systems for website and application development. Among them, web applications based on the PHP language occupy an important position among many development languages, so it is very necessary to deploy PHP in the Linux environment. In this article, we will introduce how to deploy a PHP environment in a Linux system, including the process of installing the Apache server, PHP interpreter and corresponding extension modules, so that developers can quickly build a PHP development environment.

1. Install the Apache server

Apache is an open source web server that is popular for its stability and powerful functions. In Linux systems, install the Apache server through the apt-get command. Enter the following command in the terminal:

sudo apt-get update

sudo apt-get install apache2

The installation process may You need to enter the sudo password. After the installation is complete, you can start the Apache server through the following command:

sudo systemctl start apache2

After starting the Apache server, enter the local IP in the browser The address or domain name can be used to access the Apache server successfully.

2. Install the PHP interpreter

After installing the Apache server, we need to install the PHP interpreter, otherwise the Apache server cannot parse the PHP language. In Linux systems, install the PHP interpreter through the apt-get command. Enter the following command in the terminal:

sudo apt-get install php

After the installation is complete, we need to restart the Apache server so that the server can recognize the PHP interpreter. Enter the following command in the terminal:

sudo systemctl restart apache2

After restarting the Apache server, we can create it in Apache's default WWW directory /var/www/html A PHP file to facilitate testing the operation of the PHP interpreter. In the /var/www/html directory, enter the following command through the terminal to create a test.php file:

sudo nano test.php

In the newly opened Enter the following code into the test.php file:

<?php phpinfo(); ?>

After saving the file, enter the local IP address in the browser Or the domain name/test.php can access the running status of the PHP interpreter. If everything is fine, you should see the verbose output of the PHP interpreter.

3. Install extension modules

In actual development, the PHP interpreter itself is not enough. We also need to install some extension modules to achieve richer functions. In Linux systems, use the apt-get command to install PHP extension modules. The following code is an example of a common PHP extension module installation command.

Install the MySQL extension module:

sudo apt-get install php-mysql

Install the Redis extension module:

sudo apt-get install php-redis

Install the Memcached extension module:

sudo apt-get install php-memcached

Install Imagick extension module:

sudo apt-get install imagemagick php-imagick

and so on.

After the installation is complete, you also need to restart the Apache server. Enter the following command in the terminal:

sudo systemctl restart apache2

4. Summary

The above are all the steps to deploy the PHP environment under the Linux system . In addition to the above, you can also deploy PHP environments through other methods, such as using Docker container technology and so on. You need to try a lot during development to quickly get started with the Linux development environment and improve development efficiency.
