How to deploy php to the server

With the development of the Internet, the development of websites and applications has become more and more common. PHP is a popular server-side programming language that is widely used in website and application development. In order for PHP websites or applications to run online, we need to deploy them to the server.

This article will introduce how to deploy PHP to the server, including preparations, selecting the appropriate server, installing PHP and configuration.

1. Preparation

Before we start, we need to complete the following preparations:

1.1 Determine the requirements

Before selecting the server , we need to clarify our needs. For example, the server size (CPU, memory, storage space, etc.), bandwidth, security, etc. we need. This helps us choose a server that suits our needs.

1.2 Choose the appropriate server

For the deployment of PHP applications, we can choose our own server or rent a third-party server. If we choose our own server, we need to purchase server hardware and configure it. If we choose to rent a third-party server, we can choose a cloud server or a virtual private server (VPS), etc., depending on our needs.

1.3 Select the operating system

When selecting the server, we need to select the operating system. For the deployment of PHP applications, you can usually choose between Linux or Windows operating systems. However, Linux systems are widely used in the server field because of their efficient and secure features. Therefore, in most cases we choose Linux systems.

1.4 Installing PHP dependencies

Installing PHP requires some dependencies, including web servers (such as Apache, Nginx), MySQL databases, PHP extensions, etc. Before deploying, we need to make sure these dependencies are installed.

2. Installing PHP

2.1 Installing PHP

Normally, Linux systems come with PHP pre-installed. But we still need to do some configuration work. We can install PHP and PHP extensions through the following commands:

sudo apt-get install php php-curl php-mbstring php-dom

2.2 Configuring PHP

Once installed With PHP, we need to do some configuration to ensure it can run properly on the server. We can configure it by editing the PHP configuration file php.ini:

sudo nano /etc/php/7.2/apache2/php.ini

In the php.ini file, we can configure Some important options, such as PHP error log path, PHP upload file size, etc. We can modify these options according to our needs.

3. Deploying PHP Application

Once PHP is installed and configured, we can deploy our PHP application to the server. Here are some commonly used methods:

3.1 Using FTP

If we want to simply deploy a PHP application to the server, we can use FTP. We can upload our files to the server through the FTP client and set appropriate permissions.

3.2 Using the command line

We can also use the command line to deploy PHP applications. We can use the command line tools scp or rsync to upload our application to the server and set appropriate file permissions.

4. Configuring the Web Server

Finally, we need to configure the web server so that it can run our PHP application correctly. This includes adding virtual hosts, configuring HTTP servers, etc.

4.1 Add virtual host

For the Apache server, we can configure it by creating a virtual host and edit /etc/apache2/sites-available/000-default.conf. We can add a virtual host in the following format:

ServerAdmin webmaster@localhost

DocumentRoot /path/to/your/directory

ServerName yourdomain.com

     Options Indexes FollowSymLinks

     AllowOverride All

     Require all granted

ErrorLog ${APACHE_LOG_DIR}/error .log

CustomLog ${APACHE_LOG_DIR}/access.log combined

4.2 Configure HTTP server

If we choose to use Nginx As an HTTP server, we can edit the /etc/nginx/sites-available/default file to add virtual hosts. We can add a virtual host in the following format:

server {

listen 80;

server_name yourdomain.com;

root /path/to/your /directory;

index index.php index.html;

location / {

     try_files $uri $uri/ /index.php?$args;

}

location ~.php$ {

     include snippets/fastcgi-php.conf;

     fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;

}

location ~ /.ht {

     deny all;

}

}

5. Summary

The above are the steps to deploy PHP to the server. We need to prepare the server, install PHP and dependencies, deploy the PHP application, and configure the web server. In this process, we need to pay attention to the security and performance issues of the server to ensure that our PHP applications can run well on the server.
