How to setup LAMP (Linux, Apache, Mysql, PHP) on CentOS 6.5?

LAMP is an acronym for Linux, Apache, MySQL, PHP. This instruction will describe how to install the Apache web server with PHP and MySQL support on CentOS 6.5.

In this manual, we will be using following settings:

hostname: srv1.nonamehosts.com
IP address: 192.168.1.254

As these settings will differ from yours, please replace them where appropriate.

Installing MySQL

To install MySQL, open terminal and type in these commands:

# yum -y install mysql mysql-server

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

# chkconfig --levels 235 mysqld on
# /etc/init.d/mysqld start

Once done, you can set a root MySQL password by running this command:

[[email protected] ~]# 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 orderto 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 justpress enter here.

Enter current password for root (enter for none):
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] <-- ENTER
New password: <-- yourrootsqlpassword
Re-enter new password: <-- yourrootsqlpassword
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] <-- ENTER
</span>... 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
</span>... Success!

By default, MySQL comes with a database named 'test' that anyone canaccess. 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
</span>- 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
</span>... 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!

Installing Apache

Apache is a free open source software which runs over 50% of the world’s web servers.

It is available as a CentOS package, therefore we can install it like this:

# yum -y install httpd

Now configure your system to start Apache at boot time…

# chkconfig --levels 235 httpd on

After that, you can start apache running on your VPS:

# service httpd start

Now direct your browser to http://192.168.1.254, and you should see the Apache2 test page.

Installing PHP5

PHP is an open source web scripting language that is widely used to build dynamic webpages.

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

# yum -y install php php-mysql

Once its completed, we must restart Apache:

# service httpd restart
