Install LAMP Server (Apache, MySQL, PHP) On RHEL, CentOS, Scientific Linux 6.5/6.4
LAMP is a combination of operating
system and open-source software stack. The acronym LAMP is derived from
first letters of Linux, Apache HTTP Server, MySQL database, and
PHP/Perl/Python.
In this tutorial let
us see how to setup LAMP server on RHEL/CentOS/Scientific Linux 6.x.
Here x stands for version such as 6.1, 6.2, 6.3, 6.4, 6.5 etc.
My testbox hostname and IP address are server.unixmen.local and 192.168.1.101/24, respectively.
Install Apache
Apache
is an open-source multi-platform web server. It provides a full range
of web server features including CGI, SSL and virtual domains.
To install Apache, enter the following command from your terminal:
# yum install httpd -y
Start the Apache service and let it to start automatically on every reboot:
# service httpd start # chkconfig httpd on
Allow Apache
server default port 80 through your firewall/router if you want to
connect from remote systems. To do that, edit file
/etc/sysconfig/iptables,
# vi /etc/sysconfig/iptables
Add the following lines.
[...] -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEP [...]
Restart iptables:
# service iptables restart
Test Apache:
Open your web browser and navigate to http://localhost/ or http://server-ip-address/.
Install MySQL
MySQL
is an enterprise class, open source, world’s second most used database.
MySQL is a popular choice of database for use in web applications, and
is a central component of the widely used LAMP open source web
application software stack.
To install MySQL, enter the following command:
# yum install mysql mysql-server -y
Start the MySQL service and make to start automatically on every reboot.
# service mysqld start # chkconfig mysqld on
Setup MySQL root password
By default, mysql root user doesn’t has password. To secure mysql, we have to setup mysql root user password.
# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, 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): ## Press Enter ##
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] ## Press Enter ##
New password: ## Enter new password ##
Re-enter new password: ## Re-enter new password ##
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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] ## Press 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] ## Press Enter ##
... Success!
By default, MySQL 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] ## Press 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] ## Press Enter ##
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Install PHP
PHP (recursive acronym for PHP: Hypertext Preprocessor)
is a widely used open-source general purpose scripting language that is
especially suited for web development and can be embedded into HTML.
Install PHP with following command:
# yum install php -y
Test PHP
Create a sample “testphp.php” file in Apache document root folder and append the lines as shown below:
# vi /var/www/html/testphp.php
Add the following lines.
Restart httpd service:
# service httpd restart
Navigate
to http://server-ip-address/testphp.php. It will display all the
details about php such as version, build date and commands etc.
If
you wanna to get MySQL support in your PHP, you should install
“php-mysql” package. If you want to install all php modules just you use
the command “yum install php*”
[root@server ~]# yum install php-mysql -y
Now
open the phptest.php file in your browser using
http://ip-address/testphp.php or http://domain-name/testphp.php. Scroll
down and you will see the mysql module will be presented there.
Install phpMyAdmin
phpMyAdmin
is a free open source web interface tool, used to manage your MySQL
databases. By default phpMyAdmin is not found in CentOS official
repositories. So let us install it using EPEL repository.
To install EPEL repository, follow the below link:
Now install phpMyAdmin
# yum install phpmyadmin -y
Configure phpMyAdmin
Edit the phpmyadmin.conf file.
# vi /etc/httpd/conf.d/phpMyAdmin.conf
Find and comment the whole /<Directory> section as shown below:
[...] Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin #<Directory /usr/share/phpMyAdmin/> # <IfModule mod_authz_core.c> # # Apache 2.4 # Require local # </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> [...]
Open “config.inc.php” file and change from “cookie” to “http” to change the authentication in phpMyAdmin:
# cp /usr/share/phpMyAdmin/config.sample.inc.php /usr/share/phpMyAdmin/config.inc.php # vi /usr/share/phpMyAdmin/config.inc.php
Change cookie to http.
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]
Restart the Apache service:
# service httpd restart
Now you can access the phpmyadmin console by navigating to http://server-ip-address/phpmyadmin/ from your browser.
Enter your MySQL username and password which you have given in previous steps. In my case its “root” and “centos”.
Now you will be redirected to the phpmyadmin dashboard.page as shown below.
Now you will able to manage your MariaDB databases from phpMyAdmin web interface.
That’s it. Your LAMP server is up and ready to use.
Cheers!

Install LAMP Server (Apache, MySQL or MariaDB, PHP) On Ubuntu 14.10/14.04/13.10
LAMP is a combination of operating system and open-source software stack. The acronym LAMP comes from the first letters of Linux, Apache HTTP Server, MySQL or MariaDB database, and PHP/Perl/Python.
In this tutorial, we will see how to setup LAMP server on Ubuntu 14.10 system.
Install Apache
Apache
is an open-source multi-platform web server. It provides a full range
of web server features including CGI, SSL and virtual domains.
To install Apache, enter the following command from your terminal:
sudo apt-get install apache2
Test Apache:
Open your web browser and navigate to http://localhost/ or http://server-ip-address/.
Install MySQL
MySQL
is a relational database management system (RDBMS) that runs as a
server providing multi-user access to a number of databases, though
SQLite probably has more total embedded deployments
sudo apt-get install mysql-server mysql-client
During installation, you’ll be asked to setup the MySQL root user password. Enter the password and click Ok.
Re-enter the password.
Now, MySQL server has been installed.
You can verify the MySQL server status using command:
sudo service mysql status
Sample output:
mysql start/running, process 11690
Note: If you want to use MariaDB instead of MySQL, then follow these steps.
Install MariaDB
MariaDB is a drop in replacement for MySQL. It is a robust, scalable and reliable SQL server that comes rich set of enhancements.
First
you have to remove existing MySQL packages if any. To completely
uninstall MySQL along with its configuration files, enter the following
command:
sudo apt-get purge mysql*
Run the following command to remove unwanted packages.
sudo apt-get autoremove
After removing MySQL, run the following command to install MariaDB.
sudo apt-get install mariadb-server mariadb-client
Alternatively, you can install it from MariaDB repository
if you want to try most recent version of MariaDB. Run the following
commands to add PPA. As of writing this, MariaDB PPA is not yet updated
to Ubuntu 14.10. However, we can use the repository of Ubuntu 14.04
instead.
sudo apt-get install software-properties-common sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db sudo add-apt-repository 'deb http://sgp1.mirrors.digitalocean.com/mariadb/repo/5.5/ubuntu trusty main'
Update the software sources list and install MariaDB using following commands:
sudo apt-get update sudo apt-get install mariadb-server mariadb-client
During installation you will be asked to set mysql ‘root’ user password.
Re-enter password:
Check if mariadb is running or not, using the following command:
sudo service mysql status
Sample output:
* /usr/bin/mysqladmin Ver 9.0 Distrib 5.5.40-MariaDB, for debian-linux-gnu on x86_64 Copyright (c) 2000, 2014, Oracle, Monty Program Ab and others. Server version 5.5.40-MariaDB-1~trusty-log Protocol version 10 Connection Localhost via UNIX socket UNIX socket /var/run/mysqld/mysqld.sock Uptime: 15 sec Threads: 1 Questions: 571 Slow queries: 0 Opens: 332 Flush tables: 4 Open tables: 22 Queries per second avg: 38.066
Install PHP
PHP
(recursive acronym for PHP: Hypertext Preprocessor) is a widely used
open-source general purpose scripting language that is especially suited
for web development and can be embedded into HTML.
Install PHP with following command:
sudo apt-get install php5 php5-mysql libapache2-mod-php5
To test PHP, create a sample “testphp.php” file in Apache document root folder.
sudo nano /var/www/html/testphp.php
Add the following lines.
<?php phpinfo(); ?>
Restart apache2 service:
sudo service apache2 restart
Navigate to http://server-ip-address/testphp.php. It will display all the details about php such as version, build date and commands etc.
If you want to install all php modules, enter the command sudo apt-get install php* and restart the apache2 service. To verify the modules, open web browser and navigate to http://server-ip-address/testphp.php. You will able to see all installed php modules.
Manage MySQL Databases (Optional)
Install phpMyAdmin
phpMyAdmin
is a free open-source web interface tool used to manage your MySQL
databases. It is available in the Official Debian repositories. So
install it with command:
sudo apt-get install phpmyadmin
Select the Web server you use. In my case, it is apache2.
Select ‘Yes’ to configure database for phpmyadmin wjth dbconfig-common.
Enter password of the database’s administrative user.
Enter MySQL application password phpmyadmin.
Re-enter the password.
Success, phpMyAdmin installation has been completed now.
Access phpMyAdmin Web Console
Now, you can access the phpmyadmin console by navigating to http://server-ip-address/phpmyadmin/ from your browser.
Enter your MySQL username and password which you have given in previous steps. In my case its “root” and “ubuntu”.
You will be redirected to PhpMyAdmin main web interface.
Now, you can manage your MySQL databases from phpMyAdmin web interface.
Additional Note:
if you followed all steps carefully, phpMyAdmin should work well. In
case phpMyAdmin is not working, please do the following steps. Thanks to
Mr.Nick.
1. Open terminal, and type:
sudo nano /etc/apache2/apache2.conf
2. Scroll to end and type:
Include /etc/phpmyadmin/apache.conf
3. Save and Exit
4. Restart apache service:
sudo /etc/init.d/apache2 restart
That’s it. Your LAMP server is up and running now.
