How to install LAMP on CentOS !

Since it has been around for years, LAMP (short for Linux, Apache, MySQL, and PHP) is used very commonly in the world.

How to install LAMP on CentOS

First you need to prepare a new CentOS server without any installation, here we use CentOS 6.4 64bit. You need to change hostname and edit host file before doing this .

1. Install Apache

yum install httpd

Apache configuration file path:

/etc/httpd/conf/httpd.conf

Start Apache

service httpd start

Test by visiting http: // <youraddress> you will see the message “Apache 2 Test Page”

Note : If using VPS at Vultr , the default port 80 will be blocked, when accessing the IP will be error ERR_CONNECTION_REFUSED. Please do the following open port operation:

/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/etc/rc.d/init.d/iptables save

Configure Apache Virtual Hosts

– create a configuration file in the directory  /etc/httpd/conf.d, name the example example.com.conf(replace with your domain)

File content /etc/httpd/conf.d/example.com.conf

NameVirtualHost *:80

<VirtualHost *:80> 
     ServerAdmin [email protected]
     ServerName example.com
     ServerAlias www.example.com
     DocumentRoot /var/www/example.com/public_html/
     ErrorLog /var/www/example.com/logs/error.log 
     CustomLog /var/www/example.com/logs/access.log combined
</VirtualHost>

– Create directory for website

mkdir -p /var/www/example.com/public_html
mkdir /var/www/example.com/logs

– If you want to add a website, just create another .conf file and reload Apache with the command: service httpd reload

2. Install MySQL

yum install mysql-server
service mysqld start

Proceed to install MySQL by command

/usr/bin/mysql_secure_installation

Due to a new installation, if you are asked for a password press Enter

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

Then set the root password by selecting y

Next you will have to answer a series of questions, best to choose y

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] y                                            
 ... 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] y
... 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] y
 - 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] y
 ... 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!

3. Install PHP

yum install php php-mysql

PHP Modules

PHP has a lot of different module libraries, you can see by typing the following command

yum search php-
php-bcmath.x86_64 : A module for PHP applications for using the bcmath library
php-cli.x86_64 : Command-line interface for PHP
php-common.x86_64 : Common files for PHP
php-dba.x86_64 : A database abstraction layer module for PHP applications
php-devel.x86_64 : Files needed for building PHP extensions
php-embedded.x86_64 : PHP library for embedding in applications
php-enchant.x86_64 : Human Language and Character Encoding Support
php-gd.x86_64 : A module for PHP applications for using the gd graphics library
php-imap.x86_64 : A module for PHP applications that use IMAP

To install any module use the following command

yum install name of the module

4. Automatically run the service when reboot

chkconfig httpd on
chkconfig mysqld on

Restart Apache

service httpd restart

OK, that’s the process of installing LAMP on CentOS. Need help please leave a comment . Thanks for reading .
