Add warning note about possible high CPU load problem, per http://blogs.sun.com/mandy/entry/lighttpd_smf_troubles


Running lighttpd on Solaris Service Management Facility (SMF)

If you want to use native Solaris management facility (SMF), you have to create two files describing lighttpd service:

Manifest file: /var/svc/manifest/network/lighttpd.xml

Making use of this

Import

Now import the file into SMF database:


#!ShellExample
# svccfg -v import /var/svc/manifest/network/lighttpd.xml

Enable


#!ShellExample
# svcadm enable network/lighttpd

Check


#!ShellExample
# svcs -l network/lighttpd
fmri         svc:/network/lighttpd:lighttpd
name         Lighttpd HTTP server
enabled      true
state        online
next_state   none
state_time   Sun Sep 25 14:21:49 2005
logfile      /var/svc/log/network-lighttpd:lighttpd.log
restarter    svc:/system/svc/restarter:default
contract_id  143
dependency   require_all/error svc:/network/loopback:default (online)
dependency   optional_all/error svc:/network/physical:default (online)
dependency   require_all/error svc:/milestone/multi-user-server:default (online)

Of course it is simple example of such a service, if you have better one, please cut and paste it here.

Caution!

If you experience high CPU load after enabling this service, you might want to read the Lighttpd SMF troubles blog entry. It advises to NOT have SMF set the username/groupname and instead use the server.username and server.groupname settings in the configuration file. To do so, the following section should be replaced in the lighttpd.xml file:


#!text/xml
                <!-- restrict privileges and run as user webservd -->
                <method_context>
                       <method_credential
                                user='webservd' group='webservd'
                                privileges='basic,!proc_session,!proc_info,!file_link_any,net_privaddr' />
                </method_context>

Replace that with:


#!text/xml
                <method_context/>
