This document provides an overview of Linux for web developers. It discusses setting up a development environment in Linux and some of the historical and architectural aspects of Linux. It then covers computing history in the 1960s that led to the creation of UNIX and C programming language. The document discusses key principles of UNIX and similarities to modern web standards. It provides brief biographies of important figures in the development of Linux, such as Richard Stallman and Linus Torvalds. Finally, it demonstrates setting up a basic LAMP stack and uploading files to a server without using FTP.
Intro to Linux - Skillswap
- 1. Linux @twombh Tom Buckley-Houston
- 2. Thanks | Evening | Future ● @PMStudioUK ● @iamdanw Next Skillswap: @garybristow Progressive ● ● @spyou ● @amias Enhancement ● @jmoverley Drinks in the Watershed afterwards
- 3. Linux for web developers Dev environment: Historical/Architectural: ● Everything apart from PS ● 60% websites, 25% mobile ● Wine, GIMP ● Google, Facebook, etc ● Java apps: Aptana/Netbeans ● Linux descended from UNIX, ● Better LAMP computer science, ARPANET, ● General daily usage etc. More of a direct lineage ● Philosophical reasons than Windows.
- 4. Computing Eden ● 1960s America, UNIX, C, ARPANET ● MIT, Bell Labs. ● Dennis Ritchie, Brian Kernighan, Ken Thompson.
- 5. The UNIX Way “Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.” ● The human dimension. ● Command Line Interface - CLI. ● Analogy to modern web standards; REST, W3C, etc.
- 6. Richard Stallman ● Early 1980s ● GNU: GNU's Not Unix! ● Almost made a kernel ● The GPL ● Free as in speech, not free as in beer. ● Free to do whatever you want as long as that doesn't restrict someone else doing the same. (eg; Red Hat)
- 8. Linus Torvalds ● 1991, doing a masters in Computer Science at Helsinki. ● MINIX but better license. ● The Linux Kernel.
- 9. LAMP Hello World ● You've got a server out there somewhere. ● SSH and SSH keys. ● `ssh [email protected]' ● `aptitude update' Compare with Windows ● `aptitude install apache2 mysql5-server php5 apache2-mod-php php5-mysql' ● `curl localhost' “It Works!”
- 10. Apache's Vhosts Quick way in a local environment: Just Proper way in production environment: Lots shive loads of definitions in the same of files that you can individually turn on and off. file. `nano /etc/apache2/sites-available/website' `nano /etc/apache2/conf.d/vhosts' NameVirtualHost *:80 <VirtualHost *:80> <VirtualHost *:80> ServerName myserver.com ServerName myserver.com DocumentRoot /var/www/website DocumentRoot /var/www/website </VirtualHost> </VirtualHost> `sudo a2ensite website' Creates a symbolic link from; `sudo service apache2 restart' /etc/apache2/sites-enabled/website `sudo service apache2 restart'
- 11. Uploading your project without FTP! ● `scp -r myproject/* [email protected]:/var/www/website' ● `rsync -rv myproject/* [email protected]:/var/www/website' ● `git push'
