2. Developing and Deploying These lab VMs will be going away after the semester ends These lab VMs will be going away after the semester ends How will you deploy the site? How will you deploy the site? How will you save the source code so that you or others can work on it later? How will you save the source code so that you or others can work on it later?

3. Site Maintenance Your web site is up and running, and people are using it Your web site is up and running, and people are using it You want to change a page You want to change a page You edit the page.tpl.php file. Syntax error! Site goes down! You edit the page.tpl.php file. Syntax error! Site goes down! You can't remember how to fix it. Site stays down! You can't remember how to fix it. Site stays down! You have two people editing the same file. Site down! Work lost! You have two people editing the same file. Site down! Work lost! What to do? What to do?

4. Development Strategies You will need live and development sites You will need live and development sites Devel site on your own VM Devel site on your own VM Deploy site on calvincs.com Deploy site on calvincs.com Live site on client’s dreamhost account Live site on client’s dreamhost account Ideally: one-button deployment Ideally: one-button deployment

5. Deployment Deployment means uploading your site (www directory, databases) to a host Deployment means uploading your site (www directory, databases) to a host Host must support PHP, MySQL, etc. Host must support PHP, MySQL, etc. Next lab: deployment on dreamhost (calvincs.com). Other hosts – same idea, different details Next lab: deployment on dreamhost (calvincs.com). Other hosts – same idea, different details Load your database onto their server Load your database onto their server Use FTP to load your /var/www/ directory onto their server Use FTP to load your /var/www/ directory onto their server Adjust configuration… Adjust configuration… Point your domain name to the new host Point your domain name to the new host Turn on caching Turn on caching Test Test Deploying your term project… Deploying your term project…

6. Deploying to Dreamhost Upload your database Upload your database Create a database on host Create a database on host Export development Drupal database with mysqldump Export development Drupal database with mysqldump Import your database into Dreamhost server Import your database into Dreamhost server Upload your Web directory Upload your Web directory Zip your /var/www directory Zip your /var/www directory Copy to dreamhost server Copy to dreamhost server Unzip in appropriate directory Unzip in appropriate directory Modify settings as needed Modify settings as needed settings.php – for logging in to the 1and1 database settings.php – for logging in to the 1and1 database.htaccess – for finding your files.htaccess – for finding your files

7. Revision Control: the problem… Have you ever lost work while writing a term paper? Have you ever lost work while writing a term paper? How do you collaborate on writing projects? How do you collaborate on writing projects? Have you ever made changes to a computer program that caused it to stop working? Have you ever made changes to a computer program that caused it to stop working? How would you collaborate on a development project like a website? How would you collaborate on a development project like a website? What if you have two versions of your website and need to manage merges and synchronization? What if you have two versions of your website and need to manage merges and synchronization?

8. Revision Control Revision control (or source control or version control) systems help you Revision control (or source control or version control) systems help you maintain old and new versions of code maintain old and new versions of code view and reconcile difference between versions view and reconcile difference between versions check out and check in code check out and check in code keep track of every change: who, why? keep track of every change: who, why? revert to previous versions of your code revert to previous versions of your code

9. Revision Control Systems Popular revision control systems Popular revision control systems CVS CVS old, stable old, stable used by Drupal, sourceforge used by Drupal, sourceforge Subversion (SVN) Subversion (SVN) newer, quite popular newer, quite popular Install on your own PC! Install on your own PC! Git Git Newest, maybe becoming most popular? Newest, maybe becoming most popular? Many others… Many others…
