Webplusplus was CIF's development web server running on comparable hardware to While the Webmaster Duties do not require development of Webplusplus, they may still want to work on it.

It appears that Webplusplus was decommissioned when Web1 was migrated from an Apple Xserve G5 to that !@#$ Dell PowerEdge 2850 (and its stupid RAID controller!), though we don't know that for sure. Either way, it no longer exists.

Developing on Webplusplus

Developer Account Setup

All developer accounts should be members of the www-data group in order to modify files in /var/www/ without sudo permissions. They should also be in the sudo group if they need sudo permissions. Give the permissions with the following: adduser USER_NAME www-data and adduser USER_NAME sudo

All developers should ensure that their Git commits will reflect their name and email address. Otherwise commits will not be attributed properly in the Git logs and on GitHub. The --global flag tells it to write to ~/.gitconfig instead of looking for a config file in the local repository.

git config --global user.email "[email protected]"
git config --global user.name "Full Name"

Making Changes Go Live

When work is completed on Webplusplus, it should be tested in Internet Explorer 7+, Firefox, Chrome, Safari, and possibly Opera on OS X and Windows (where applicable) to ensure that the changes are functional cross-browser. Once this has been confirmed, changes should be merged to the develop branch (if working on a branch for the changes to be made, like a responsible person) and then merged into master and pushed to the repository. Be sure to switch back to the develop branch after pushing master!

git checkout master
git merge develop
git push origin master
git checkout develop

Changes will then need to be pulled onto This can be done by running git pull origin master on Web1 from the /var/www/ directory.

Swapping to Production

Swapping Webplusplus to be our production server should be done sparingly and only when web1 needs to go down for significant maintenance or experiences hardware issues. If swapping Webplusplus to production is necessary, follow these steps:

  • Copy the wp-content/uploads/ directory from where WordPress is located on web1 to the equivalent directory on Webplusplus.
  • Ensure that wp-content/plugins/ has the same plugins that are present in that directory on web1.
  • wp-content/themes/cif/theme-config.php: Change the values of THEME_DEBUG and USE_DEBUG_CONSTANTS to be false.
  • panel/panel-config.php: Change the value of PANEL_URL to use the cif.rochester.edu domain instead of the webplusplus subdomain.
  • /etc/apache2/sites-available/default: Change the values of ServerName and the Redirect line to use the cif.rochester.edu domain instead of the webplusplus subdomain.
  • /etc/apache2/sites-available/default-ssl: Change the value of ServerName to use the cif.rochester.edu domain instead of the webplusplus subdomain.
  • /etc/apache2/sites-available/panel: Change all WebAuthReturnURL lines to use the cif.rochester.edu domain instead of the webplusplus subdomain.
  • Import the WordPress database from [[On [web1], run mysqldump -u wordpress -p wordpress > wordpress.sql to dump the database as the wordpress MySQL user. Then move this file to Webplusplus and run mysql -u root -p wordpress < wordpress.sql to import it as the root MySQL user. The database dump should then be deleted.
  • Restart Apache on Webplusplus with service apache2 restart.
  • Give Webplusplus an IP address in the lower half for the time being so that it is visible off campus. Edit /etc/network/interfaces to have Webplusplus pull its new IP address. Finally, update the DNS records in Labmaster to make www alias to Webplusplus and to change the non-web1 entry with web1's IP address (the entry with cif.rochester.edu as its FQDN) to point to Webplusplus.
  • Restart the machine to restart the network interface with reboot.

To switch Webplusplus back to development, revert the changes made in the above steps. Webplusplus's original IP address was ###.###.220.186

After swapping to or from production, some things in WordPress may need to be updated.

  • If the events calendar is not updating correctly, go to Settings → Google Calendar Events and click Refresh on the CIF Events feed. This will reset the events cache.

Swapping to Development

Webplusplus was set up with a database dump from Web1. To have WordPress use links to webplusplus.cif.rochester.edu instead of cif.rochester.edu, the database records will need to be updated. Log into the MySQL console with mysql -u wordpress -p wordpress and run the following:

UPDATE cifpipes_options SET option_value=replace(option_value, 'https://cif.rochester.edu', 'https://webplusplus.cif.rochester.edu') WHERE option_name='home' OR option_name='siteurl';
UPDATE cifpipes_posts SET guid=replace(guid, 'https://cif.rochester.edu','https://webplusplus.cif.rochester.edu');
UPDATE cifpipes_posts SET post_content=replace(post_content, 'https://cif.rochester.edu', 'https://webplusplus.cif.rochester.edu');
UPDATE cifpipes_postmeta SET meta_value=replace(meta_value, 'https://cif.rochester.edu','https://webplusplus.cif.rochester.edu');

Setup

Webplusplus should be set up following the same steps as Web1#Setup, with the exception of these considerations:

Webplusplus Specific Setup

On Webplusplus, the develop branch of the GitHub repo should be used for development. Switch to the develop branch and pull it.

 git checkout -b develop
 git pull origin develop
SASS and Compass will be necessary for compiling the stylesheets. Install them with 
 sudo apt-get install ruby-sass ruby-compass
