Installing LAMP (Linux, Apache, MariaDB, PHP/PhpMyAdmin) in RHEL/CentOS 7.0

Skipping the LAMP introduction, as I’m sure that most of you know what is all about. This tutorial will concentrate on how to install and configure famous LAMP stack – Linux Apache, MariaDB, PHP, PhpMyAdmin – on the last release of Red Hat Enterprise Linux 7.0 and CentOS 7.0, with the mention that both distributions have upgraded httpd daemon to Apache HTTP 2.4.

Install LAMP in CentOS 7
Install LAMP in RHEL/CentOS 7.0


Depending on the used distribution, RHEL or CentOS 7.0, use the following links to perform a minimal system installation, using a static IP Address for network configuration.

For RHEL 7.0
  1. RHEL 7.0 Installation Procedure
  2. Register and Enable Subscriptions/Repositories on RHEL 7.0
For CentOS 7.0
  1. CentOS 7.0 Installation Procedure

Step 1: Install Apache Server with Basic Configurations

1. After performing a minimal system installation and configure your server network interface with a Static IP Address on RHEL/CentOS 7.0, go ahead and install Apache 2.4 httpd service binary package provided form official repositories using the following command.

# yum install httpd
Install Apache in CentOS 7
Install Apache Web Server

2. After yum manager finish installation, use the following commands to manage Apache daemon, since RHEL and CentOS 7.0 both migrated their init scripts from SysV to systemd – you can also use SysV and Apache scripts the same time to manage the service.

# systemctl status|start|stop|restart|reload httpd


# service httpd status|start|stop|restart|reload


# apachectl configtest| graceful
Start Apache in CentOS 7
Start Apache Web Server

3. On the next step start Apache service using systemd init script and open RHEL/CentOS 7.0 Firewall rules using firewall-cmd, which is the default command to manage iptables through firewalld daemon.

# firewall-cmd --add-service=http

NOTE: Make notice that using this rule will lose its effect after a system reboot or firewalld service restart, because it opens on-fly rules, which are not applied permanently. To apply consistency iptables rules on firewall use –permanent option and restart firewalld service to take effect.

# firewall-cmd --permanent --add-service=http
# systemctl restart firewalld
Enable Firewall in CentOS 7
Enable Firewall in CentOS 7

Other important Firewalld options are presented below:

# firewall-cmd --state
# firewall-cmd --list-all
# firewall-cmd --list-interfaces
# firewall-cmd --get-service
# firewall-cmd --query-service service_name
# firewall-cmd --add-port=8080/tcp

4. To verify Apache functionality open a remote browser and type your server IP Address using HTTP protocol on URL (http://server_IP), and a default page should appear like in the screenshot below.

Apache Default Page
Apache Default Page

5. For now, Apache DocumentRoot path it’s set to /var/www/html system path, which by default doesn’t provide any index file. If you want to see a directory list of your DocumentRoot path open Apache welcome configuration file and set Indexes statement from to + on <LocationMach> directive, using the below screenshot as an example.

# nano /etc/httpd/conf.d/welcome.conf
Apache Directory Listing
Apache Directory Listing

6. Close the file, restart Apache service to reflect changes and reload your browser page to see the final result.

# systemctl restart httpd
Apache Index File
Apache Index File

Step 2: Install PHP5 Support for Apache

7. Before installing PHP5 dynamic language support for Apache, get a full list of available PHP modules and extensions using the following command.

# yum search php
Install PHP in CentOS 7
Install PHP in CentOS 7

8. Depending on what type of applications you want to use, install the required PHP modules from the above list, but for a basic MariaDB support in PHP and PhpMyAdmin you need to install the following modules.

# yum install php php-mysql php-pdo php-gd php-mbstring
Install PHP Modules in CentOS 7
Install PHP Modules
Install PHP mbstring Module
Install PHP mbstring Module

9. To get a full information list on PHP from your browser, create a info.php file on Apache Document Root using the following command from root account, restart httpd service and direct your browser to the http://server_IP/info.php address.

# echo "<?php phpinfo(); ?>" > /var/www/html/info.php
# systemctl restart httpd
Check PHP Info in CentOS 7
Check PHP Info in CentOS 7

10. If you get an error on PHP Date and Timezone, open php.ini configuration file, search and uncomment date.timezone statement, append your physical location and restart Apache daemon.

# nano /etc/php.ini

Locate and change date.timezone line to look like this, using PHP Supported Timezones list.

date.timezone = Continent/City
Set Timezone in PHP
Set Timezone in PHP

Step 3: Install and Configure MariaDB Database

11. Red Hat Enterprise Linux/CentOS 7.0 switched from MySQL to MariaDB for its default database management system. To install MariaDB database use the following command.

# yum install mariadb-server mariadb
Install MariaDB in CentOS 7
Install MariaDB in CentOS 7

12. After MariaDB package is installed, start database daemon and use mysql_secure_installation script to secure database (set root password, disable remotely logon from root, remove test database and remove anonymous users).

# systemctl start mariadb
# mysql_secure_installation
Start MariaDB Database
Start MariaDB Database
Secure MySQL Installation
Secure MySQL Installation

13. To test database functionality login to MariaDB using its root account and exit using quit statement.

mysql -u root -p
MariaDB > quit
Connect MySQL Database in CentOS
Connect MySQL Database

Step 4: Install PhpMyAdmin

14. By default official RHEL 7.0 or CentOS 7.0 repositories doesn’t provide any binary package for PhpMyAdmin Web Interface. If you are uncomfortable using MySQL command line to manage your database you can install PhpMyAdmin package by enabling CentOS 7.0 rpmforge repositories using the following command.

# yum install

After enabling rpmforge repository, next install PhpMyAdmin.

# yum install phpmyadmin
Enable RPMForge in CentOS 7
Enable RPMForge Repository

15. Next configure PhpMyAdmin to allow connections from remote hosts by editing phpmyadmin.conf file, located on Apache conf.d directory, commenting the following lines.

# nano /etc/httpd/conf.d/phpmyadmin.conf

Use a # and comment this lines.

# Order Deny,Allow
# Deny from all
# Allow from
Allow Remote PhpMyAdmin Access
Allow Remote PhpMyAdmin Access

16. To be able to login to PhpMyAdmin Web interface using cookie authentication method add a blowfish string to phpmyadmin file like in the screenshot below using the generate a secret string, restart Apache Web service and direct your browser to the URL address http://server_IP/phpmyadmin/.

# nano /etc/httpd/conf.d/phpmyadmin.conf
# systemctl restart  httpd
Add Blowfish in PhpMyAdmin
Add Blowfish in PhpMyAdmin
PhpMyAdmin Dashboard
PhpMyAdmin Dashboard

Step 5: Enable LAMP System-wide

17. If you need MariaDB and Apache services to be automatically started after reboot issue the following commands to enable them system-wide.

# systemctl enable mariadb
# systemctl enable httpd
Enable Services System Wide
Enable Services System Wide

That’s all it takes for a basic LAMP installation on Red Hat Enterprise 7.0 or CentOS 7.0. The next series of articles related to LAMP stack on CentOS/RHEL 7.0 will discuss how to create Virtual Hosts, generate SSL Certificates and Keys and add SSL transaction support for Apache HTTP Server.

  1. hi,
    plz guide me how to configure phpmyadmin bcause i am not accessing that and i m receving this nessages


    You don’t have permission to access /phpmyadmin on this server.

    Apache/2.2.15 (CentOS) Server at Port 80

  2. Your installation instructions are great! But I am having issues accessing phpMyAdmin from a remote computer, even adding in the internal IP address of the client machine.

    • Hi.
      Thanks a lot!
      Add your network between

      15 Require ip
      16 Require ip 192.168.0.
      17 Require ip ::1

  3. From an install today (2014/07/24) the phpmyadmin.conf file name has been re-cased to:


    So the location is:


  4. Yes …you are right…I think they have removed phpmyadmin from rpmforge repositories. A few days ago the packages was there and working. Remove rpmforge from your system and install phpMyAdmin from sources:

    yum remove rpmforge-release
    tar xfz phpMyAdmin-4.2.6-english.tar.gz
    mv phpMyAdmin-4.2.6-english/ phpmyadmin
    cp -r phpmyadmin/ /usr/share/
    nano /etc/httpd/conf.d/phpmyadmin.conf

    Here add this lines:


    Order Deny,Allow
    Deny from all
    Allow from ## Use your IP/Network CDIR
    Require all granted

    Alias /phpmyadmin /usr/share/phpmyadmin
    Alias /phpMyAdmin /usr/share/phpmyadmin
    Alias /mysqladmin /usr/share/phpmyadmin

    systemctl restart httpd.service

    cp /usr/share/phpmyadmin/ /usr/share/phpmyadmin/

    nano /usr/share/phpmyadmin/

    Add blowfish pass as explained above ( and you’re ready!
