1. Get a separate account set up for ghost to use

     echo ghost:x:5001:5001::/opt/ghost:/bin/false >> /etc/passwd
     echo ghost::5001: >> /etc/group
    
  2. Exctract the zip file

     unzip ghost-0.3.3.zip -d /opt/ghost
     cd /opt/ghost
     npm install --production
     cp config.example.js config.js
     chown -R ghost:ghost .
    
  3. Tweak config.js as appropriate

  4. Create a manifest with manifold (Here's the one I created. Note the tweak to alter the NODE_ENV):

     <?xml version="1.0"?>
     <!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1">
     <!--
             Created by Manifold
     -->
     <service_bundle type="manifest" name="ghost">
       <service name="site/ghost" type="service" version="1">
         <create_default_instance enabled="false"/>
         <single_instance/>
         <dependency name="network" grouping="require_all" restart_on="error" type="service">
           <service_fmri value="svc:/milestone/network:default"/>
         </dependency>
         <dependency name="filesystem" grouping="require_all" restart_on="error" type="service">
           <service_fmri value="svc:/system/filesystem/local"/>
         </dependency>
         <method_context>
           <method_credential user="ghost" group="ghost"/>
         </method_context>
         <exec_method type="method" name="start" exec="/opt/local/bin/npm start" timeout_seconds="60">
           <method_context>
             <method_environment>
               <envvar name="NODE_ENV" value="production"/>
             </method_environment>
           </method_context>
         </exec_method>
         <exec_method type="method" name="stop" exec=":kill" timeout_seconds="60"/>
         <property_group name="startd" type="framework">
           <propval name="duration" type="astring" value="child"/>
           <propval name="ignore_error" type="astring" value="core,signal"/>
         </property_group>
         <property_group name="application" type="application">
           <propval name="config_file" type="astring" value="/opt/ghost/config.js"/>
         </property_group>
         <stability value="Evolving"/>
         <template>
           <common_name>
             <loctext xml:lang="C">
                         Ghost Blogging Software
                     </loctext>
           </common_name>
         </template>
       </service>
     </service_bundle>
    
  5. Configure nginx to proxy your connections

     server {
         listen       80;
         server_name  blog.shalman.org;
         location / {
             proxy_set_header Host $host;
             proxy_pass http://localhost:2368;
         }
     }
    
  6. Bounce nginx, launch ghost!

     svccfg import /opt/ghost/ghost.xml
     svcadm restart nginx
     svcadm enable ghost
