Install Linux, Apache, MySQL, PHP (LAMP) On CentOS 6
Login via ssh root
To install apache, open terminal and type in this command:
yum install httpd
Once it installs, you can start apache running on your VPS:
service httpd start
MySQL is a powerful database management system
To install MySQL,
yum install mysql-server
service mysqld start
During the installation, MySQL will ask you for your permission twice. After you say Yes to both, MySQL will install.
Once it is done installing, you can set a root MySQL password:
The prompt will ask you for your current root password.
Since you just installed MySQL, you most likely won’t have one, so leave it blank by pressing enter.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Then the prompt will ask you if you want to set a root password. Go ahead and choose Y and follow the instructions.
CentOS automates the process of setting up MySQL, asking you a series of yes or no questions.
It’s easiest just to say Yes to all the options. At the end, MySQL will reload and implement the new changes.
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
Remove anonymous users? [Y/n] y
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
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...
- Removing privileges on test database...
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
PHP is an open source web scripting language that is widely used to build dynamic webpages.
To install PHP
yum install php php-mysql
Once you answer yes to the PHP prompt, PHP will be installed.
PHP also has a variety of useful libraries and modules that you can add onto your server. You can see the libraries that are available by typing:
yum search php-
Terminal then will display the list of possible modules. The beginning looks like this:
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 see more details about what each module does, type the following command into terminal, replacing the name of the module with whatever library you want to learn about.
yum info name of the module
Once you decide to install the module, type:
yum install name of the module
You can install multiple libraries at once by separating the name of each module with a space.
Congratulations! You now have LAMP stack on your droplet!
We should also set the processes to run automatically when the server boots (php will run automatically once Apache starts):
chkconfig httpd on
chkconfig mysqld on
