Next is the network configuration, can configure the network address according to own actual situation.

Time zone setting, select the appropriate city according to your time zone.

Next, set the root password, because root is the system administrator user, so set a strong password to prevent cracking.

In installing the application interface, because we want to install the lamp environment, the main point is "now custom".

In server, check the World Wide Web server.

Point "optional Packages", select the modules that need to be installed, and install Apache, MySQL, and PHP modules by default.

After that, you will be prompted to install the discs and prepare the disks.

The next step is the installation process and the halfway system prompts for a swap.

After the installation is complete, a configuration interface is entered.

In the firewall settings, we need to open the HTTP port because we want to set up the site.

You can then create a personal account that is not managed to use.

After the reboot, it completes the installation, enters the CentOS login interface, enters the login user root and the root password to log in.

After you enter the username and password, you enter the CentOS main interface.

In system-administration-services, check the httpd and mysqld to enable the service to start automatically.

<?php
Phpinfo ();
?>

Using Firefox to open http://127.0.0.1/info.php, if shown as a graphical interface, PHP has been configured successfully.

Thus, a complete lamp (linux+apache+mysql+php) environment is installed.
