How To Install PHP on Linux

PHP is one of the popular opensource server side scripting language mostly used in web development. PHP originally stood for "Personal Home Page", but it now stands for the recursive backronym PHP: Hypertext Preprocessor.
Today I'm going to show you how to install PHP on Linux

First things first, You need to install apache web server first.. Because often we use PHP incombination with Apache.. See, How To Install Apache On Different Linux Distros...

After installing the Apache web server successfully... start to install PHP..

Installing PHP On Ubuntu

Following command will install PHP and libapache2-mod-php5, php5-mcrypt modules.. which are useful for web developers..

sudo apt-get install php5 libapache2-mod-php5 php5-mcrypt php5-mysql

Or, On Newer systems (Ubuntu 16.04 and later versions..)

sudo apt install php libapache2-mod-php php-mcrypt php-mysql

PHP has a variety of useful libraries and modules that you can add onto your virtual server. You can see the libraries that are available.

Run, apt-cache search php- (For Ubuntu 16.04) or apt-cache search php5- (For Ubuntu 14.04) to see the list of possible/available modules.

If you would like to install one of the available modules.. Run command like one shown below..

sudo apt-get install name_of_the_module

sudo apt install name_of_the_module

Installing PHP On CentOS, RHEL and Fedora Linux

For Fedora 22 and later versions..

sudo dnf -y install php php-mysql

For CentOS, RHEL, Fedora 21 and earlier..

sudo yum -y install php php-mysql

To list available modules for PHP, Run the following command..

dnf search php-

Or (For CentOS, RHEL and older Fedora systems..)

yum search php-

If you would like to install one of the available modules.. Run command like one shown below..

sudo dnf name_of_the_module

sudo yum name_of_the_module

Installing PHP On Arch Linux

First, make sure that your Arch Linux System is up-to-date by running following command

sudo pacman -Syu

Now Install PHP with following command..

sudo pacman -S php

Installing PHP On SUSE Linux

Run following command to install PHP on SUSE Linux..

sudo zypper install php5 apache2-mod_php5

Installing PHP On Gentoo Linux

Run the following command to ensure that your Gentoo Linux System is up-to-date..

sudo emerge --sync && sudo emerge --update world

Now run the following command to install PHP on Gentoo..

sudo emerge -pv php

That's it.. ☻

Basic Package Management With RPM command

The RPM Package Manager (RPM) is a powerful command line driven package management system capable of installing, uninstalling, verifying, querying, and updating software packages for RPM based Linux Distros. This is adopted by many Linux Distros such as Red Hat Enterprise Linux, Fedora , SUSE Linux, openSUSE, CentOS, Meego, Mageia and many others.
It is also used on many other operating systems as well, and the RPM format is part of the Linux Standard Base .

Working with the rpm command

The rpm command performs the most common package-management functions, along with a host of uncommon functions as well. The table below lists the main operations you can perform with the rpm command and the command-line options to specify the given operations.

rpm command operations :

Operation	Short Option	Long Option
Upgrade/install	-U	--upgrade
Install	-i	--install
Remove	-e	--erase
Query	-q	--query
Verify	-V	--verify
Check signature	-K	--checksig
Freshen (upgrade) already-installed package	-F	--freshen
Initialize database	None	--initdb
Rebuild database	None	--rebuilddb

Using this table as a guide, you can explore the options to the rpm command. To install or upgrade a package, use the -U command-line option:

rpm -U filename.rpm

Or , You can also use rpm -i filename.rpm for installation but you can use rpm -U filename.rpm for both installation and Upgrading purpose.

Please note that you need to log in as root, or use the su command to change to the root user to install the software using rpm command:

For example, to install the mlocate RPM used as an example in this chapter, run the following command:

rpm -U mlocate-0.22.2-2.i686.rpm

To get extra feedback, you can use a command like the following, with the -h and -v options in conjunction with the -U option:

rpm -Uhv mlocate-0.22.2-2.i686.rpm

When you run this command you will see more output than the default, which is no output unless there are errors. With the -h option, the rpm command will print a series of hash marks, #, to provide feedback that the command is still running. With the -v option, the rpm command provides more verbose messages.

To remove a package (called erase in RPM terminology), use the -e command-line option:

rpm -e package_name

Notice that you install a package file using the file name that ends in .rpm, but uninstall or erase a package without the .rpm extension. This is because you install RPM files, but once installed, you work with the installed packages. The file name and the package name do not have to correspond, but typically (and sanely) they have the same base name.

To list every RPM package installed on your system, use a command like the following.

rpm -qa

Expect to wait while this command completes. Most Linux systems have numerous packages installed, which will result in many lines of output. To better see the output, you can pipe this command to the more command, as shown following:

rpm -qa | more

You will then see the package listing one screen at a time.
