In today's rapidly developing Internet era, cloud computing technology is increasingly used. As an important form of cloud computing, cloud servers are used by more and more enterprises and individuals. Building a PHP environment on a cloud server and providing website services are essential skills for many webmasters. The following is an article about setting up a PHP environment on a cloud server. I hope it will be helpful to you.
1. Choose a suitable cloud server
First of all, you need to choose a suitable cloud server. Choose the appropriate configuration and operating system based on your needs. Here we take the CentOS system on Alibaba Cloud as an example.
2. Install the web server
The first step in setting up the environment is to install a web server such as Apache or Nginx. Here we take Apache as an example. Use the following command to install Apache in the terminal:
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
At this time, by accessing the public IP address of the cloud server, browse Enter the IP address into the server and you will see the default page of Apache, indicating that Apache has been successfully installed.
3. Install php
Next, install php. Use the following command to install php in the terminal:
sudo yum -y install php php-mysql
After the installation is completed, restart the Apache service:
sudo systemctl restart httpd.service
4. Test the php environment
After the installation is completed, you can pass the following command Verify whether PHP is installed successfully:
sudo vim /var/www/html/info.php
Enter the following content in the info.php file:
After saving and exiting the file, enter the public IP address of the cloud server in the browser, Add /info.php, that is:
http://你的IP地址/info.php
to see PHP related information, such as PHP version, configuration file path, etc., indicating 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.
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:

gd is a Extension for working with images. Use the following command to install the gd extension in the terminal:

mbstring is a Extensions for handling multibyte encodings. Use the following command to install the mbstring extension in the terminal:
sudo yum install php-mbstring
After the installation is complete, restart the Apache service:
sudo systemctl restart httpd.service

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 upload_max_filesize = 20M # 设置上传文件大小限制
After the modification is completed, save and exit.
7. Summary
