Install Apache, PHP And MySQL On CentOS 7 (LAMP)

This tutorial shows how you can install an Apache2 webserver on a CentOS 7.0 server with PHP5 support (mod_php) and MySQL support. LAMP is short for Linux, Apache, MySQL, PHP.

1 Preliminary Note

In this tutorial, I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

I will add EPEL-7 repo here to install latest phpMyAdmin as follows:

rpm -ivh http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm

2 Installing MySQL 5

To install MySQL, we do install mariadb like this:

yum -y install mariadb-server mariadb

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

systemctl start mariadb.service
systemctl enable mariadb.service

Set passwords for the MySQL root account:

mysql_secure_installation

[root@server1 ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): <--ENTER
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n]
New password: <--yourmariadbpassword
Re-enter new password: <--yourmariadbpassword
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <--ENTER
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <--ENTER
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <--ENTER
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <--ENTER
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
[root@server1 ~]#

3 Installing Apache2

CentOS 7.0 ships with apache 2.4. Apache2 is directly available as a CentOS 7.0 package, therefore we can install it like this:

yum -y install httpd

 [root@server1 ~]# yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: ftp.plusline.de
 * extras: mirror.23media.de
 * updates: mirror.23media.de
Package httpd-2.4.6-17.el7.centos.1.x86_64 already installed and latest version
Nothing to do
[root@server1 ~]#

By default apache will be installed, if-not then please install it as shown above

Now configure your system to start Apache at boot time...

systemctl start httpd.service

systemctl enable httpd.service

In CentOS 7.0 uses Firewall-cmd, so I will customize it to allow external access to port 80 (http) and 443 (https).

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Now direct your browser to http://192.168.0.100, and you should see the Apache2 placeholder page:

4 Installing PHP5

We can install PHP5 and the Apache PHP5 module as follows:

yum -y install php

We must restart Apache afterwards:

 systemctl restart httpd.service

5 Testing PHP5 / Getting Details About Your PHP5 Installation

The document root of the default website is /var/www/html. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.

vi /var/www/html/info.php

<?php
phpinfo();
?>

Now we call that file in a browser (e.g. http://192.168.0.100/info.php):

As you see, PHP5 is working, and it's working through the Apache 2.0 Handler, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don't have MySQL support in PHP5 yet.

6 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

yum search php

Pick the ones you need and install them like this:

yum -y install php-mysql

In the next step I will install some common PHP modules that are required by CMS Systems like Wordpress, Joomla and Drupal:

yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel

Now restart Apache2:

 systemctl restart httpd.service

Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules like curl etc there.:

7 phpMyAdmin installation

phpMyAdmin is a web interface through which you can manage your MySQL databases.
phpMyAdmin can now be installed as follows:

yum install phpMyAdmin

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):

vi /etc/httpd/conf.d/phpMyAdmin.conf

[...]
Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin #<Directory /usr/share/phpMyAdmin/> # <IfModule mod_authz_core.c> # # Apache 2.4 # <RequireAny> # Require ip 127.0.0.1 # Require ip ::1 # </RequireAny> # </IfModule> # <IfModule !mod_authz_core.c> # # Apache 2.2 # Order Deny,Allow # Deny from All # Allow from 127.0.0.1 # Allow from ::1 # </IfModule> #</Directory> <Directory /usr/share/phpMyAdmin/> Options none AllowOverride Limit Require all granted </Directory>

[...]

Next we change the authentication in phpMyAdmin from cookie to http:

vi /etc/phpMyAdmin/config.inc.php

[...]
$cfg['Servers'][$i]['auth_type']     = 'http';    // Authentication method (config, http or cookie based)?
[...]

Restart Apache:

systemctl restart  httpd.service

Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:


    Apache: http://httpd.apache.org/
    PHP: http://www.php.net/
    MySQL: http://www.mysql.com/
    CentOS: http://www.centos.org/
    phpMyAdmin: http://www.phpmyadmin.net/

links at the bottom of the page, says 8, only 5 listed.

  of the 5 listed, everything after php points to php.net instead of their desired target

From:

Thnak you for pointing out the broken link targets, it is fixed now. 8 is the number of the chapter here, not the number of the links.

From: Gavin

The Fedora package has been upreved. It is now epel-release-7-1.noarch.rpm

Hello, just wanted to let you know that you actually installed an old phpMyAdmin package. There are two PMA packages, "phpmyadmin" which installs v2.11.11 and "phpMyAdmin" which installs v3.5.7. I don't know if you wanted to use the old version intentionally, but I just thought that I'd point it out.

From:

The tutorial has been updated to a newer phpmyadmin version now.

From:

Why mariaDB and not mysql, or are they the same now ?

From: admin

MariaDB is the free MySQL fork, MariaDB is compatible with MySQL and the commands from MariaDB are still nemad "mysql" or "mysqldump", so there are no differences from the Client side. All Major Linux Distributions replaced MySQL with MariaDB now, so we will use that for the tutorials as well. Some users also Report that MariDB is faster then MySQL in the latest releases.

FYI, this process installed PHP 5.4.16, not PHP 5.5.x:

#  php -v

Following the article, I just installed the phpMyAdmin-4.2.7.1.
And, after install, and doing the comments suggested in the lines of Directory  for phpMyAdmin, it doesn't show in the webpage. I did  to include this lines to see it in the url:

 <Directory "/usr/share/phpMyAdmin/">
   Options Indexes
    AllowOverride None
    Require all granted
</Directory>

Any alternative?

From: Nick

Thanks for the one stop instructions. Everything worked as expected. Very common setup for CMS systems.

Step one, installing EPEL can be done by simply installing it with yum, since it is included in the default repository;

yum install epel-release

From: Jonathan

Strange, but true...

I could net get access to my new site after extracting it to the html folder until I disabled selinux.

I was able to access info.php no problem, but not index.php or / "root"

From: PatL

Thanks for this howtoforge LAMP/CentOS7

Just one point... which annoyed me; you should consider changing all MySQL terms by MariaDB... or at least mention MySQL only as a reference and only once as it is not about installing MySQL at all but MariaDB (MySQL has been thrown out by many Linux distros as of now) my 2 cents ... but again thanks a lot for this howtoforge tutorial which saved me a lot of research time ;-)

I was able to get this all installed and working.  Only problem I am having is I cannot login to phpmyadmin from my laptop to my headless CentOS server.  It will not take my login credentials on root, my regular user account, or leaving it blank.  I can login to both the root and my user account via my ssh connection to the server with no problem.  But the same accounts will not work via the web page.  I get the prompt, but it just keeps reprompting me.  Any ideas on what to check?
