Increase SWAP if have 512 MB or below

$> sudo dd if=/dev/zero of=/swap bs=1M count=1024
$> sudo mkswap /swap
$> sudo swapon /swap
$> nano /etc/fstab
# add the following line
/swap swap swap sw 0 0
# reboot and verify with the "free" command that you now have above 1GB of swap

Install basic packages

$> apt-get install php5-curl php5-gd

# php5-gd is for wordpress thumbnails

For Ruby on Rails servers

Now on its own post http://tech.yipp.ca/ruby/putting-ruby-rails-production-debian-virtualmin/

The post Create a new Debian server with Virtualmin appeared first on Techy Things.

$> sudo dd if=/dev/zero of=/swap bs=1M count=1024
$> sudo mkswap /swap
$> sudo swapon /swap

To make permanent, add this line to /etc/fstab

/swap swap swap sw 0 0

Install Passenger

$> gem install passenger
$> apt-get install apache2-threaded-dev libapr1-dev libaprutil1-dev
$> passenger-install-apache2-module

At the end it will display for you what to add to apache global conf file, in my case :

LoadModule passenger_module /usr/local/lib/ruby/gems/2.1.0/gems/passenger-5.0.30/buildout/apache2/mod_passenger.so
 <IfModule mod_passenger.c>
 PassengerRoot /usr/local/lib/ruby/gems/2.1.0/gems/passenger-5.0.30
 PassengerDefaultRuby /usr/local/bin/ruby
 </IfModule>

Also put something similar to this in the virtual host Apache config :

DocumentRoot /home/cbuy/public_html/public
RailsEnv production
ErrorLog /var/log/virtualmin/community-buy.ca_error_log
CustomLog /var/log/virtualmin/community-buy.ca_access_log combined
ScriptAlias /cgi-bin/ /home/cbuy/cgi-bin/
ScriptAlias /awstats/ /home/cbuy/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /home/cbuy/public_html/public>
allow from all
AllowOverride All
Options FollowSymLinks -MultiViews Indexes
</Directory>

Restart Apache

Troubleshooting

Generic error

Check where you can access the log file with

$> passenger-config --detect-apache2

"We're sorry, but something went wrong."

Edit Apache VirtualHost configuration to run development mode to see the error:

RailsEnv development

Then restart Apache.

"This web application process is being run as user 'nobody' and group 'nogroup' and must be able to access its application root directory"

chown your app dir so that your user can access it. If you use virtualmin that is your domain account user.

Problem: Only accessible on localhost

Solution: RAILS_ENV=production rails server -b 0.0.0.0

Problem

Forbidden

You don't have permission to access / on this server.

Solution

You might have uploaded files as root or such that is not accessible by the Apache/passenger.

chown -R <user>:<user> /home/<user>/public_html

Problem : It doesnt work

Solution

RAILS_ENV=production bundle exec rake assets:precompile

config.serve_static_assets = true

First you select your virtual server, in this example "chatzone.tv", then expend "Services" and select "Configure Website":

Then click on "Document Options", it will bring you to this view:

Then turn on "Generate Multiviews" and don't forget to select "Selected below" !!

Then Restart Apache.

Wow that's such bad UX implementation... but that's another story

Important additional steps if you have HTTPS

Redo the steps above for your SSL endpoint if you want the same to work under https. Select your virtual server, in this example "chatzone.tv", then expend "Services" and select "Configure Website SSL". Then proceed as above!

Troubleshooting

Did you restart Apache? Try rebooting if you don't know how to restart it.

If you are on raw Apache without Virtualmin, just write this in httpd.conf

Options Indexes FollowSymLinks MultiViews ExecCGI
AddType application/x-httpd-php .php

The AddType is important otherwise it won't work, even if you PHP files are currently executing correctly when accessed with the .php extension.

There are two ways to create subdomains. The way I prefer is this:

Click on "Create Virtual Server"

Select "Sub-server" as the type of virtual server on the top links.

In domain name, type the full domain name (without http://) but including the primary domain. For example: node.chatzone.tv

You will then get a new folder as the www root :
/home/chatzone/domains/node.chatzone.tv

Et voilà !

If you want to run node.js on it, read my post about Running Node.js applicaiton with Virtualmin.
