This is a simple guide to setup LAMP (Linux, Apache, MySQL and PHP). I am assuming you have Linux (Fedora 15) installed. The following commands will install the necessary packages to run Apache, MySQL and PHP.
su #for root login, enter password when prompted yum install mysql-server service mysqld start mysqladmin -u root password PASSWORD_HERE yum install phpmyadmin
Now, you should have necessary packages installed.
To run the apache and mysql services, enter the following in command prompt. This should be done each time you need to use unless you want those services to start with your OS.
su #for root login, enter password when prompted service mysqld restart service httpd restart
The directory where you can put in your files is /var/www/html/ and you can access phpMyAdmin by navigating to http://localhost/phpmyadmin
If you want the services to start with your OS, you will need to run the following:
su #for root login, enter password when prompted chkconfig --add httpd chkconfig httpd on chkconfig --add mysqld chkconfig mysqld on
Hope this helps.
