VPS for WordPress basics [Part 8] - Installing PHP

As you know, WordPress is written entirely in PHP language so VPS to run it you need to have a PHP application processor, because PHP is a language independent so if you do not install the PHP application server will become "blind PHP" should not be handled in that code.

I. How to install PHP

Like install other packages (in section 7 we installed package name to install Apache httpd webserver), we also use the command yum action is install the package namedphp php-mysql .

But , before you install we need to check the current version of PHP with the Yum package is how much, type the command sudo yum info php and returns results like this:

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

Even in the Version section, you will see its version is now 5.3.3, PHP 5.3.3 ie. But according to my experience you need to upgrade to PHP 5.4.x version so it does not fail with one of the new plugin now because they use many of the new features in PHP 5.4 and to use opcode cache if you want.

Yum To Upgrade Package, namely php package name, we will use a repository(understood as the repository for updates of the package).

The first is to install wget on VPS:

1	sudo  yum install  wget y

Then use the command wget to download the rpm package (running both 2 orders):

1 2 3

wget http: // dl .fedoraproject.org / pub / epel / 6 / x86_64 / epel-release-6-8 .noarch.rpm   wget http: // RPMS .famillecollet.com / enterprise / remi-release-6 .rpm

You can use the command ls to view the downloaded file.

Then proceed to run this with the command rpm package 2.

1	sudo  rpm -Uvh remi-release-6 * .rpm epel-release-6 * .rpm

Return results:

1 2 3 4 5

warning: remi-release-6.rpm: Header V3 DSA / SHA1 Signature, key ID 00f97f56: NOKEY warning: epel-release-6-8.noarch.rpm: Header V3 RSA / SHA256 Signature, key ID 0608b895: NOKEY Preparing ... ########################################### [100% ] 1: epel-release ########################################### [50 %] 2: remi-release ########################################### [100 %]

I heard something warnings no problem at all should you keep reassuring dentist.

Next, edit the file  /etc/yum.repos.d/remi.repo :

1	sudo  vi  / etc / yum .repos.d / remi .repo

Search for:

1 2 3 4 5 6 7

[Remi] Les RPM de remi name = pour Enterprise Linux 6 - $ basearch # Baseurl = http: //rpms.famillecollet.com/enterprise/6/remi/$basearch/ mirrorlist = http: //rpms.famillecollet.com/enterprise/6/remi/mirror enabled = 0 gpgcheck = 1 gpgkey = file: /// etc / PKI / rpm-gpg / RPM-GPG-KEY-remi

Instead  enabled = 0 to  enabled = 1 .

Save and exit.

Ok, now let's run the command yum info php to check the version, it will become version 4.5.33 as under:

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20

Available Packages Name: php Arch: i686 Version: 4.5.33 Release: 2.el6.remi Size: 2.7 M Repo: remi Summary: PHP scripting language for creating dynamic web sites URL: http://www.php.net/ License: BSD and PHP and Zend Description: PHP is an HTML-embedded scripting language. PHP Attempts to make : It easy for developers to write dynamically generated web pages.

Okay, install only.

1	sudo  yum install  php php-mysql php-devel y

Installed, type the command php-v to see the version of PHP installed on the VPS.

1 2 3 4

[Thach @ vpscanban ~] $ php-v PHP 4.5.33 (cli) (built: Sep 20 2014 16:04:53) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies

Finally, restart httpd.

1	sudo  service httpd restart

II. Test run a PHP file

To view your PHP have a good run, as well as view the information there. Create one php file name in any of your VirtualHost directories with content that:

1	<? Php phpinfo (); ?>

Then run this file with the address http: //IP-of-VPS/ten-file.php. The results page will display information about the version of PHP you are.

III. Configure PHP

PHP configuration file called php.ini and is stored in the directory / etc . To be sure your php.ini file which contains this, type the search command file name below:

1	sudo  find  / php.ini -iname

This means your command to find the php.ini file in the / (root directory).

1 2	[Thach @ vpscanban ~] $ sudo  find  / php.ini -iname / Etc / php ini

Actually, now you do not need to edit it anywhere, but if after this when using WordPress, you have not enough memory error for such PHP php.ini file will be opened up to increase the memory, and the other set . Generally you do not really get it now, it just needs to know where the php.ini file is located.

 Epilogue

After you have done this then you've come to be regarded as 80% of the total number of steps to build a webserver on a VPS. Be sure to take the time to review the previous post if you have not learn to master the basic knowledge of Linux over, too.

In the next article, I will guide you to install MySQL Server and MySQL operations necessary to your later convenience database administrator.
