LAMP (Linux + Apache + MySQL/MariaDB + Perl/PHP/Python) is a set of open-source software programs often used to set up dynamic websites or servers. These independent programs are usually used together and increasingly compatible with one another to form a powerful web application platform.
This tutorial guides you through the following process: starting a TencentDB instance and configuring a LAMP application with a CVM instance to connect to the high-availability environment of the TencentDB instance.
The database can be separated from the environment lifecycle after you run the TencentDB instance. This allows you to connect multiple servers to the same database for simplified database OPS, eliminating your concerns over database installation, deployment, version update, and troubleshooting.

The TencentDB and CVM instances used in the tutorial reside in the same region. If this is not the case, see Access via Public Network.

Initializing the TencentDB Instance

For more information on how to purchase and initialize TencentDB instances, see Purchase Method and Initializing a TencentDB for MySQL Instance.

Logging in to the CVM Instance

For more information on how to purchase and access CVM instances, see Getting Started with Linux-based CVM. CentOS is used in this tutorial.

Installing the MySQL Client

1. Install the MySQL client to the CVM instance with yum.

   yum install mysql -y

   
2. Connect to the TencentDB instance after the installation is completed.

   mysql -h hostname -u username -p

   
   Here, "hostname" is the private IP of the TencentDB instance and "username" is the username of your database.
3. After the connection is successful, you can close the instance and proceed to the next step.

   quit;

Installing the Apache Service

1. Install Apache in the CVM instance with yum.

   yum install httpd -y

   
2. Start the Apache service.

   service httpd start

3. Test Apache.

   In this step, you should configure an inbound rule with the source being all and the port protocol being TCP:80 in the security group of your CVM instance. For more information on how to configure the security group, see Security Group.

   Enter http://xxx.xxx.xxx.xxx/ in your local browser (where xxx.xxx.xxx.xxx is the public IP of your CVM instance). If the following page appears, Apahce has started successfully.
   

Installing PHP

1. Install PHP in the CVM instance with yum.

   yum install php -y

   

Creating a Project to Test the LAMP Environment

1. Create an info.php file in the /var/www/html directory of the CVM instance. Below is the sample code:

   <?php phpinfo(); ?>

2. Restart the Apache service.

   service httpd restart

3. Enter http://xxx.xxx.xxx.xxx/info.php in your local browser (where xxx.xxx.xxx.xxx is the public IP of your CVM instance). If the following page appears, the LAMP service has been deployed successfully.
