Solaris SMF: Define File Dependency

Thu, 15 May 2014 00:00:00 +0000

One of the biggest benefits of migrating to the Service Management Framework is that we can introduce dependencies to a services, these dependencies can be other services which is very valuable, however they can also be file based. This can be used in a number of ways, say for example you have some application trees that live on some NFS mounts, in the event that the mount hasn’t been successfully mounted it will still attempt to start the service. However if we make our service dependent on the file, then if the file doesn’t exist it won’t even attempt to start the service.

Solaris SMF: Define Service Execution User

Wed, 14 May 2014 00:00:00 +0000

Frequently we want a service to execute as a non-root user, this is pretty trivial in the context of the Service Management Facility in Solaris. This article will go over exactly what goes into that. The one complexity around that is the environment, if you have environment variables that the user will depend on those, they will need to be setup inside of the SMF. I will not be going into that in this article.

Solaris SMF: Delegate Service Control

Tue, 13 May 2014 00:00:00 +0000

In many of the environments that I deliver to a client we have a concept of an “environment account” this account is the credential set that the environment runs as. Over time and the maturation of the Service Management Facility (SMF) we have been able to simplify this offering and increase its capabilities. Today we are going to talk about allowing the environment user to manage a service controlled by SMF.

Solaris 11: DNS Client Configuration Using Svccfg

Wed, 23 May 2012 00:00:00 +0000

In Solaris 11, alot of configurations are being moved from configuration files into the Service Management Framework. Here we will discuss this change around the DNS client.

View Existing DNS Client Configuration

 bash
 
 
svccfg -s network/dns/client listprop config
config application
config/value_authorization astring solaris.smf.value.name-service.dns.client
config/domain astring test.local
config/nameserver net_address 10.0.0.152

Update Existing DNS Client Configuration

Here we will update our name servers. In this case we are replacing the original with two different addresses.

Solaris 11: Change Hostname Using Svccfg

Tue, 22 May 2012 00:00:00 +0000

When Solaris 11 was released more configurations were moved into the service management framework, and moved out of configuration files, one of these changes was the hostname/nodename.

View Hostname in SMF

This will read back the configuration out of the SMF.

 bash
 
 
svccfg -s system/identity:node listprop config
config application
config/nodename astring solaris11box
config/loopback astring solaris11box

Change Hostname in SMF

We have two separate settings, which need to be updated.
