sudo yum update
sudo yum install httpd

After the installation is complete, start the Apache service and set it to start at boot:

sudo systemctl start httpd.service
sudo systemctl enable httpd.service

sudo yum -y install php php-mysql

After the installation is complete, restart the Apache service:

<code><code>##<pre class='brush:php;toolbar:false;'>sudo systemctl restart httpd.service</pre><code>

4. Test the php environment

After the installation is completed, you can verify whether PHP is successfully installed by using the following command:

sudo vim /var/www/html/info.php

Enter in the info.php file The following content:

<?php phpinfo(); ?>

After saving and exiting the file, you can see it by entering the public IP address of the cloud server in the browser and adding /info.php, that is:

http://你的IP地址/info.php

PHP related information, such as PHP version, configuration file path, etc., indicates that the PHP environment has been successfully established.

5. Install php extensions

In php applications, you need to install some php extensions to run properly. Here are some common extension installation methods.

Install curl extension

curl is a tool used to transmit data. Many PHP applications require curl extension. Use the following command to install the curl extension in the terminal:

sudo yum install php-curl

After the installation is complete, restart the Apache service:

<code><code><pre class='brush:php;toolbar:false;'>sudo systemctl restart httpd.service</pre><code>

gd is an extension for processing images. Use the following command to install the gd extension in the terminal:

sudo yum install php-gd

<code><code><pre class='brush:php;toolbar:false;'>sudo systemctl restart httpd.service</pre><code>

mbstring is an extension for handling multi-byte encodings. Install the mbstring extension in the terminal using the following command:

sudo yum install php-mbstring

<code><code><pre class='brush:php;toolbar:false;'>sudo systemctl restart httpd.service</pre><code>

TIPS: According to different application requirements, you can also install mysqli extension, imagick extension, etc.

6. Configure php.ini

By modifying the php.ini file, you can configure some configurations for the operation of php, such as setting time zone, upload file size limit, etc.

Use the following command to open the php.ini file:

sudo vim /etc/php.ini

Find the following configuration items to modify:

display_errors = On              # 显示错误信息
date.timezone = Asia/Shanghai    # 设置时区
