Linux for web developersDev 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.
Computing Eden ● 1960s America, UNIX, C, ARPANET ● MIT, Bell Labs. ● Dennis Ritchie, Brian Kernighan, Ken Thompson.
The UNIX Way“Write programs that do one thing and do it well.Write programs to work together. Write programsto handle text streams, because that is a universal interface.”● The human dimension.● Command Line Interface - CLI.● Analogy to modern web standards; REST, W3C, etc.
Richard Stallman ● Early 1980s ● GNU: GNUs 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 doesnt restrict someone else doing the same. (eg; Red Hat)
Linus Torvalds ● 1991, doing a masters in Computer Science at Helsinki. ● MINIX but better license. ● The Linux Kernel.
LAMP Hello World● Youve got a server out there somewhere.● SSH and SSH keys.● `ssh email@example.com● `aptitude update Compare with Windows● `aptitude install apache2 mysql5-server php5 apache2-mod-php php5-mysql● `curl localhost “It Works!”
Apaches VhostsQuick way in a local environment: Just Proper way in production environment: Lotsshive 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
Uploading your project without FTP!● `scp -r myproject/* firstname.lastname@example.org:/var/www/website● `rsync -rv myproject/* email@example.com:/var/www/website● `git push
