Keep in mind that if you enter 2 for the strongest level, you will receive errors when attempting to set any password which does not contain numbers, upper and lowercase letters, and special characters, or which is based on common dictionary words. This is not to be confused with the system root. The database root user is an administrative user with full privileges over the database system. Even though the default authentication method for the MySQL root user dispenses the use of a password, even when one is set , you should define a strong password here as an additional safety measure.
This will remove some anonymous users and the test database, disable remote root logins, and load these new rules so that MySQL immediately respects the changes you have made. This will connect to the MySQL server as the administrative database user root , which is inferred by the use of sudo when running this command.
You should see output like this:. Even though this might look like a security concern at first, it makes the database server more secure because the only users allowed to log in as the root MySQL user are the system users with sudo privileges connecting from the console or through an application running with the same privileges.
Your MySQL server is now installed and secured. PHP is the component of your setup that will process code to display dynamic content. It can run scripts, connect to your MySQL databases to get information, and hand the processed content over to your web server so that it can display the results to your visitors.
Once again, leverage the apt system to install PHP. Run the following command to install all three packages and their dependencies:. Currently, if a user requests a directory from the server, Apache will first look for a file called index. We want to tell the web server to prefer PHP files over others, to make Apache look for an index. To make this change, open the dir. Move the PHP index file highlighted above to the first position after the DirectoryIndex specification, like this:.
After this, restart the Apache web server in order for your changes to be recognized. You can do that with the following command:. You can also check on the status of the apache2 service using systemctl :.
To extend the functionality of PHP, you have the option to install some additional modules. To see the available options for PHP modules and libraries, pipe the results of apt search into less , a pager which lets you scroll through the output of other commands:.
The results are all optional components that you can install. It will give you a short description for each:. To learn more about what each module does, you could search the internet for more information about them.
Alternatively, look at the long description of the package by typing:. There will be a lot of output, with one field called Description which will have a longer explanation of the functionality that the module provides.
If, after researching, you decide you would like to install a package, you can do so by using the apt install command like you have been doing for the other software. If you want to install more than one module, you can do that by listing each one, separated by a space, following the apt install command, like this:.
At this point, your LAMP stack is installed and configured. When using the Apache web server, you can use virtual hosts similar to server blocks in Nginx to encapsulate configuration details and host more than one domain from a single server. Apache on Ubuntu The underlying platform is LAMP based.

Menu Help Create Join Login. One advantage of LAMP is the substantial flexibility for different database, web server, and scripting languages. While Nginx, Cherokee and Lighttpd can replace Apache.
The fastest way to get started is to install LAMP using tasksel. To install a LAMP server:. Run a script, or browse to a page of the application, to install the database needed by the application. Once the steps above, or similar steps, are completed you are ready to begin using the application.
A disadvantage of using this approach is that the application files are not placed in the file system in a standard way, which can cause confusion as to where the application is installed. Another larger disadvantage is updating the application. When a new version is released, the same process used to install the application is needed to apply updates. Depending on the application some extra configuration and setup steps may be needed, however.
Written in PHP, and accessed through a web browser, phpMyAdmin provides a graphical interface for database administration tasks.
Before installing phpMyAdmin you will need access to a MySQL database either on the same host as that phpMyAdmin is installed on, or on a host accessible over the network. For more information see MySQL documentation. From a terminal prompt enter:. At the prompt choose which web server to be configured for phpMyAdmin. The rest of this section will use Apache2 for the web server. This file contains configuration options that apply globally to phpMyAdmin. Also, be sure that the phpMyAdmin host has permissions to access the remote database.
