How to deploy php project (tutorial)

PHP is a widely used server-side scripting language. Many websites use PHP as the back-end language. If you develop a PHP project, the next step you need to do is to deploy it to a server so that it can be accessed through the Internet. In this article, I will introduce the steps to deploy a PHP project and the problems you may encounter.

Step 1: Obtain a server

Before deploying a PHP project, you need to purchase or rent a server. If you are not familiar with server operation and maintenance, you can choose to use a cloud server. Suppliers such as Alibaba Cloud and Tencent Cloud all provide cloud server services. Choosing a cloud server that is stable and cost-effective can greatly simplify your deployment work.

Step 2: Install the necessary software

Deploying the PHP project on the server requires installing several necessary software first:

1. Web server (such as Apache or Nginx )
2. PHP interpreter
3. Database server (such as MySQL)

In cloud servers, these software are usually pre-installed, you only need to go to the management panel Just start the service in . If you are using a server you built yourself, you need to install these software manually.

Step 3: Upload PHP files

Before deploying the PHP project, you need to upload the source files and related files to the server. You can use FTP software to upload files to the server. Before uploading, make sure you have uploaded all dependencies, libraries, and configuration files.

Step 4: Configure the Web server

The Web server is responsible for receiving client requests and returning responses. You need to configure the web server to correctly recognize and handle PHP files. Here's how to configure Apache and Nginx:

1. Apache

In Apache, you need to enable the mod_php extension to be able to handle PHP files. Add the following code to Apache's main configuration file (usually the httpd.conf file) to enable the mod_php extension:

LoadModule php5_module modules/libphp5.so

Then, you need to add the following code Add to Apache's virtual host configuration file (usually the httpd-vhosts.conf file):

ServerName example.com
DocumentRoot /path/to/project
<Directory /path/to/project>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

This configuration file specifies the root directory and access permissions of the virtual host. Finally, you need to restart the Apache server for the configuration to take effect.

2. Nginx

In Nginx, you need to use the PHP FastCGI process manager to process PHP files. Add the following code in Nginx's main configuration file (usually the nginx.conf file) to enable the FastCGI process manager and process PHP files:

location ~ .php$ {

    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

This configuration The file specifies the address of the PHP process manager and the rules for processing PHP files. Finally, you need to restart the Nginx server for the configuration to take effect.

Step 5: Configure the database

If your PHP project needs to use a database, you need to install and configure a database server (such as MySQL) on the server. In MySQL, you need to follow these steps to create a database and user so that PHP applications can connect to the database:

1. Log in to the MySQL server using the root user.
2. Run the following command to create a new database:

CREATE DATABASE dbname;

Replace "dbname" with your desired database name.

3. Run the following command to create a MySQL user and grant it access to the newly created database:

GRANT ALL PRIVILEGES ON dbname.* TO 'username'@' localhost' IDENTIFIED BY 'password';

Replace "dbname" with your desired database name, "username" with your desired username, and "password" with your desired password.

Step 6: Test the application

After completing the above steps, you need to test whether your PHP application has been installed and configured correctly. Open your web browser, enter the server address or domain name in the address bar, and go to your application's homepage. If everything is configured correctly, you should see your application rendered in the browser.

If you encounter any problems, you can check the Apache or Nginx error logs and PHP log files to find the source of the problem.

Summary

In this article, we introduced the basic steps of PHP project deployment. You need to obtain a server, install the necessary software, upload source files and configure the web server and database. After completing these steps, you can successfully run your PHP application on the server.
