Detailed explanation of how to deploy PHP environment variables on Alibaba Cloud

Deploying PHP environment variables on Alibaba Cloud is a way to build a PHP code running environment on cloud server ECS. Deploying PHP environment variables allows developers to use the operating system, web server, and PHP version of your choice. In this article, we will discuss how to deploy PHP environment variables on Alibaba Cloud.

Step one: Select an ECS instance and operating system

Select an instance in Alibaba Cloud ECS that meets your needs and budget for deployment. Regarding the choice of operating system, if you already have relevant web development experience, it is recommended to choose a familiar operating system, such as CentOS, Ubuntu or Windows Server.

Step 2: Select the Web server

For the Web server, we recommend using the Apache Web server or Nginx Web server on Alibaba Cloud ECS. If you want to use an Apache server, you can use the script installation channel, which provides Apache installation scripts for operating systems such as CentOS, Debian, Ubuntu, and more. If you want to use an Nginx server, you can use an image to install it. The Nginx image on Alibaba Cloud ECS supports operating systems such as Debian and Ubuntu.

Step 3: Install PHP

When installing the PHP environment on Alibaba Cloud ECS, we recommend choosing to install the latest version of PHP through a mirror. You can select the operating system and PHP version on the cloud server ECS console and click the "Install PHP" button to install PHP. At the same time, you can also install php through yum, as shown below:

$ sudo yum install php

Step 4: Set PHP environment variables

By default, after installing PHP, no further settings are required. PHP is available. However, in some cases, you may need to customize some PHP environment variables.

For example, if you want to use a specific PHP configuration file, you can add the following entry in Apache's vhost file:

SetEnv  PHP_INI_PATH=/path/to/php.ini

In addition, you can also set it through PHP's ini_set function PHP environment variable:

ini_set('variable_name', 'variable_value');

In PHP, when you need to update the value of the PHP_INI_PATH environment variable, you can call the following code:

putenv('PHP_INI_PATH=/path/to/php.ini');

Step 5: Test whether PHP is running normally

Once PHP and Web server are installed in your Alibaba Cloud ECS, you need to test whether PHP is running normally. To do this, you need to create a PHP file, upload it to your web server and access the file.

On your host, create a file called index.php. Then add the following content to the file:

<?php phpinfo();
?>

Upload the index.php file to your web server (for example, in the /var/www/html directory), and then access the file in your browser. If you see the PHP version and more information about the PHP environment, it means that the PHP environment variables you set up on Alibaba Cloud ECS are already working properly.

Summary

By deploying PHP environment variables, you can quickly build a PHP development environment that suits you. On Alibaba Cloud ECS, you can flexibly choose the operating system, web server, and PHP version so that you can create a PHP running environment that best suits you. At the same time, you can also verify whether the PHP environment variables you deployed on Alibaba Cloud are correct by setting the PHP environment variables and testing whether they run normally.
