Detailed explanation of the steps to install and start Linux PHP

For many programmers, Linux and PHP are important development tools. However, like any other system and software, installing and launching Linux and PHP can cause many problems. Here is a simple guide to install and start Linux and PHP.

Step One: Install Linux

Linux installation usually starts from bootable media (such as DVD or USB). Boot the computer from the media to enter the installation program, and then follow the prompts to complete the installation process. In the installer, you need to select the packages you want to install. Therefore, make sure you choose to install Apache web server and PHP.

After the installation is complete, you need to configure the network so that the server can be accessed. This is the command used:

sudo ifconfig eth0 192.168.1.100 netmask 255.255.255.0
sudo route add default gw 192.168.1.1
sudo echo "nameserver 8.8.8.8" >> /etc /resolv.conf

The above command assumes the Ethernet interface is eth0, sets the IP address to 192.168.1.100, the gateway is 192.168.1.1, and uses the Google public DNS server.

Step 2: Install PHP

After the Linux installation is completed, you need to install PHP. Install PHP using the following command:

sudo apt-get install php7.0

Please note that in the above command, you need to change the PHP version to the version you need to install.

Step Three: Configure Apache

Apache needs to be configured correctly to use with PHP. In the file /etc/apache2/mods-enabled/dir.conf, find the following line:

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

And make sure index.php is in the list. Otherwise, you can add it manually as follows:

DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

Next, enable it using the following command Apache and PHP:

sudo a2dismod mpm_event
sudo a2enmod mpm_prefork
sudo a2enmod php7.0
sudo service apache2 restart

Step 4: Test your installation

Finally, you need to test your installation and make sure it is working. To do this, you can create a file called test.php that contains the following code:

phpinfo();
?>

Save And placed in the root directory of the Web server. You can then view the PHP information by entering the server's IP address or domain name into your web browser and adding "/test.php" after the URL. If you can see the PHP information page, your installation and configuration are correct.

Summary

Installing and starting up Linux and PHP may seem complicated, but it's actually a simple matter. As long as you follow the steps above, you can easily install and launch your development environment so you can start writing PHP code.
