How to install LAMP environment on Ubuntu

Everyone knows that LAMP is a collection of open source software used as a production environment for website servers. Here I will briefly tell you how to install the LAMP environment on the currently popular Linux version Ubuntu.

Step 1: Install Apache

It’s still necessary to update it first, right? sudo apt-get update sudo apt-get install apache2

It's that simple, it's over! Check whether the installation is successful: directly enter the IP of the VPS in the browser and see if anything similar to "It works!" appears? Yes, that’s ok! Don’t know your IP? Try: ifconfig eth0 | grep inet | awk ‘{ print $2 }’

Step 2: Install MySQL

sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

During the MySQL installation, you will be asked to enter the MySQL root password. If you miss it, it doesn't matter. You can modify it in the shell later.

Start MySQL: After the installation is complete, we enter sudo mysql_install_db to start

Technical MySQL setup script: sudo /usr/bin/mysql_secure_installation

Then you will be prompted to enter the root password: Enter current password for root (enter for none): OK, successfully used password, moving on…

You will be asked whether you need to change your password. Select N here and continue with the following steps. The next step is to simply enter yes and no until MySQL restarts: 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…

This completes MySQL. Next, let’s work on PHP.

The third step, install PHP

Enter sudo apt-get install php5 libapache2-mod-php5 php5-mcrypt

After you are prompted to confirm YES twice, PHP will start to install itself.

It may be useful for you to set a default file in the PHP directory (not necessary) sudo nano /etc/apache2/mods-enabled/dir.conf

Join:

Direc"Undescriptable"yIndex index.php index.html index.cgi index.pl index.php index.xhtml index.htm

PHP has many useful components that can help you:

Input apt-cache search php5-

A lot will be displayed next, probably like this: hp5-cgi – server-side, HTML-embedded scripting language (CGI binary) php5-cli – command-line interpreter for the php5 scripting language php5-common – Common files for packages built from the php5 source php5-curl – CURL module for php5 php5-dbg – Debug symbols for PHP5 php5-dev – Files for PHP5 module development php5-gd – GD module for php5 php5-gmp – GMP module for php5 php5-ldap – LDAP module for php5 php5-mysql – MySQL module for php5 php5-odbc – ODBC module for php5 php5-pgsql – PostgreSQL module for php5 php5-pspell – pspell module for php5 php5-recode – recode module for php5 php5-snmp – SNMP module for php5 php5-sqlite – SQLite module for php5 php5-tidy – tidy module for php5 php5-xmlrpc – XML-RPC module for php5 php5-xsl – XSL module for php5 php5-adodb – Extension optimizing the ADOdb database abstraction library php5-auth-pam – A PHP5 extension for PAM authentication […]

Once you have selected the modules you want to install just enter a command similar to this: sudo apt-get install name of the module

You can install one or more components at a time.

Want to continue? Gone!

The fourth step is to check your PHP information on the server

Create a file: sudo nano /var/www/info.php and add: Save and exit!

Next restart Apache: sudo service apache2 restart

You can see what you need and what you are missing under: http://ip/info.php!

It’s gone!
