Installing PHP and MySQL in a Red Hat environment is one of the basic steps to build a Web development environment. This article will detail the specific steps to install PHP and MySQL on Red Hat systems and provide corresponding code examples. I hope that through the guidance of this article, you can successfully set up a PHP and MySQL environment and prepare for web development work.

1. Install PHP

Log in to the Red Hat system and open the terminal.
Use the following command to update the system package list:
```
sudo yum update

Install PHP and related plug-ins:
```

2. Install MySQL

Install the MySQL database server:
```
sudo yum install mysql-server
```
Copy after login
Start the MySQL service and set the boot time:
```
sudo systemctl start mysqld
sudo systemctl enable mysqld
```
Copy after login
Run the MySQL security script to Improve security:
```
sudo mysql_secure_installation
```
Copy after login
Follow the prompts to set the MySQL root password, remove anonymous users, disable root remote login, etc.
Verify whether MySQL is installed successfully:
```
mysql -u root -p
```
Copy after login
Enter the root password and successfully log in to mysql, which means the installation is successful.

3. Connect PHP to MySQL

Create a new PHP file in the Web directory, such as test.php:
```
sudo vi /var/www/html/test.php
```
Copy after login

Edit test.php and enter the following code:

connect_error) {
  die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully!";
?>

Copy after login

Save and exit the editor, then visit http://localhost/test.php to check whether the connection is successful to the MySQL database.

Through the above steps, you have successfully installed PHP and MySQL on the Red Hat system and established the connection between them. This will provide a stable environment for your web development work. Hope this article can be helpful to you.
