How to package and deploy PHP programs in Linux environment?

With the rapid development of the Internet, the development and deployment of Web applications have become more and more important. In the development environment, we can run and test our PHP program directly on the server, but when it comes to actual deployment, we need to package and install the program into the production environment. This article will introduce how to package and deploy PHP programs in a Linux environment and provide some code examples.

1. Preparation

Before starting, we first need to make sure that we have installed PHP on the Linux server. We can check the installation of PHP through the following command:

$ php -v

If the output results show the version information of PHP, it means that PHP has been installed successfully.

2. Packaging the PHP program

In order to facilitate deployment and maintenance, we need to package the PHP program into an executable file. In the Linux environment, we can use the Phar tool to achieve this.

Phar is a self-contained PHP archive file format, similar to a JAR file. It can contain PHP code, configuration files, static resources, etc., and can be executed directly from the command line. The following is a simple example:

First, we need to create a directory to store our PHP program files. Let's say we name it "myapp".

$ mkdir myapp

Then, we create an entry file index.php in this directory and write a simple code:

<?php
echo "Hello, World!";

Next, we use the Phar tool to package this directory:

$ php -d phar.readonly=0 /usr/local/bin/phar pack myapp.phar -f myapp/

The -d phar.readonly=0 parameter in this command is used to set the Phar tool to writable mode, /usr/local/bin/phar is The path and name of the Phar tool, pack is the command of the Phar tool, myapp.phar is the file name after we package it, -f myapp/ means to package The directory is myapp.

If all goes well, we will get a Phar archive named myapp.phar, which will contain our PHP program code.

3. Deploy the PHP program

Now that we have successfully packaged our PHP program, the next step is to deploy it to the production environment.

First, we need to copy the myapp.phar file to a specific directory on our server, such as /var/www/html:

$ cp myapp.phar /var/www/html

Then, we need to set up the Apache configuration file to allow the server Ability to process and execute Phar files. Open the Apache configuration file /etc/httpd/conf/httpd.conf and add the following content:

<Directory "/var/www/html">
    AllowOverride All
    Options +ExecCGI
    AddHandler application/x-httpd-php .php .phar
    Require all granted
</Directory>

Save the configuration file and restart the Apache service:

$ sudo systemctl restart httpd

Finally, access http in the browser ://yourdomain.com/myapp.phar If everything goes well, you will see a page that says "Hello, World!"

So far, we have successfully packaged and deployed the PHP program in the Linux environment. Hope this article is helpful to you!
