Hello LAMP

In this post are a lot of util snippets, tips and concepts for start with the LAMP stack acronym for (Linux, Apache, MySql, PHP)

This tutorial is done in Debian 8, but it works similarly in various unix systems.

Installing the LAMP stack on Debian

Remember to update system’s repository list before:

$ sudo apt update

And later install the updates:

$ sudo apt-get upgrade

Installing Apache2

$ sudo apt-get install apache2

Starts the apache server:

$ sudo /etc/init.d/apache2 start

Stops the apache server:

$ sudo /etc/init.d/apache2 stop

Restarts the apache server:

$ sudo /etc/init.d/apache2 restart

Installing MySql

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

Installing PHP

$ sudo apt-get install php5

Add the Virtual Host path

For “create a custom local domain” we need to configure a virtual hosts

Step 1: Edit/See apache2.conf

Let’s open the apache2.conf file in this file are written the main configurations of the apache server, then it is an important file.

$ sudo gedit /etc/apache2/apache2.conf

By default we are allowed to create virtuals hosts whose document root is under /var/www directory.

Step 2: Create an apache virtual host

Enter to the apache2/sites-enabled folder:

$ cd /etc/apache2/sites-enabled

In this folder we are going to create a basic .conf file for our virtual host

$ sudo gedit my-syte.conf

Inside this file put the following lines:

<VirtualHost *:80>
	ServerName mysitedomain.com
	DocumentRoot "/var/www/my-site-root-folder"

Save the file and restart apache.

Now, we need to create the “/var/www/my-site-root-folder” folder which is the root folder acording the the last configuration file:

$ sudo mkdir /var/www/my-site-root-folder

Step 3: Allow your computer to recognize your local domain

Let’s going to modify the hosts file:

$ sudo gedit /etc/hosts

The last command open a file like the following:	localhost	debian

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Add the following line to the hosts file:	mysitedomain.com

Now, wen we type mysitedomain.com in the browser url system is going to read the host file and search the domain if exists then system is going to open the info located at the specified Document Root in the step 2.

Short snippets for permissions

There are 3 main commands for deal with permissions in UNIX, chmod, chown and chgrp

If you wish to see the permisions for files and directories in a folder type de following command:

$ ls -l

Example output:

-rwxrwxr-x  1 www-data www-data  5434 Sep 23 07:21 wp-activate.php
drwxrwxr-x  9 www-data www-data  4096 Jan 13 23:34 wp-admin
-rwxrwxr-x  1 www-data www-data   364 Dec 19  2015 wp-blog-header.php

The permission info is liste in the first group of letters, if the item is a directory the first letter is a d, otherwise if the item is a file the first letter is a minus sign -.

About chmod command

Chmod is used for change the permisions of a file, there are 3 permissions: read, write and execute.
