1. Make a server on centos Environment
2. Setting up some environment (php and apache environment)
3. Touch the file and paste the web-shell sample code.
4. Check Accessibility using public IP.

sudo yum install httpd  #安装apache
sudo systemctl start httpd.service #启动apache
sudo yum install php #安装php环境
sudo yum php-mysql    #安装php mysql
sudo systemctl restart httpd.service   #重启apache
sudo vim /var/www/html/webshell.php # paste the below source code.

创建php文件内容：

// webshell sample
<?php
system('cat /etc/hosts');
?>

Then, access to the link with url parameters.
