Hi,
Not pretending to invent something truly unique I wanted to post this
code anyway with hope that someone might find it useful.
The end product of our build is a bunch of MSI files and before
pushing them to QA we usually perform basic testing of complete
application at the integration environment. This environment consists
from half a dozen machines which emulate production environment and
allow us to run our automated smoke-test suit.
The remote deployment question was discussed in this conference quite
a few times and the most common suggestion I believe was to use
variations of remote exec which in our case did not provided enough
feedback information if something went wrong. What I opted out for is
to use WMI components from System.Management namespace and couple of
simple C# scripts. WMI objects necessary for the task are supplied with
Windows servers and Windows XP Pro as well so you don't need to look
for third party tools and I included sample script in the email:
<script language="C#">
<references>
<includes name="System.Management.dll"/>
</references>
<imports>
<import name="System.Management"/>
</imports>
<code><![CDATA[
public static void ScriptMain(Project project) {
try {
project.Log(Level.Info, "Target server: {0}",
project.Properties["deploy.remotesvr"]);
ManagementScope scope = new
ManagementScope(project.Properties["deploy.remotesvr"]+"\\root\\cimv2");
scope.Connect();
uninstall(scope, project,
project.Properties["deploy.remotesvr.product"]);
install(scope, project
, project.Properties["deploy.remotesvr.msipath"]
+ project.Properties["msi.name"]
, project.Properties["deploy.remotesvr.targetdir"]);
} catch (Exception ex) {
project.Log(Level.Error, ex.ToString());
throw;
}
}
public static void uninstall(ManagementScope scope, Project
project, string product) {
try {
project.Log(Level.Info, "\nStart removing {0}", product);
SelectQuery query = new SelectQuery("select * from
Win32_Product where name = '" + product + "'");
ManagementObjectSearcher searcher = new
ManagementObjectSearcher(scope, query);
foreach (ManagementObject envVar in searcher.Get())
{
project.Log(Level.Info, "Uninstalling {0}",
envVar["Name"]);
object res = envVar.InvokeMethod("Uninstall", null);
project.Log(Level.Info, "Uninstall result {0}", res);
}
project.Log(Level.Info, "Uninstall completed for " +
product);
} catch (Exception ex) {
project.Log(Level.Warning, ex.ToString());
}
}
static void install(ManagementScope scope, Project project, string
msi, string targetDir) {
try {
project.Log(Level.Info, "\nInstalling " + msi + " \n into "
+ targetDir);
ManagementClass installer = new ManagementClass(scope, new
ManagementPath("Win32_Product"), new ObjectGetOptions());
object[] methodArgs = {msi, "TARGETDIR=" + targetDir,
true};
object res = installer.InvokeMethod("Install", methodArgs);
if ((UInt32)res != 0)
throw new Exception("Install error " + res.ToString());
else
project.Log(Level.Info, "Succesfully installed {0}",
msi);
} catch (Exception ex) {
project.Log(Level.Error, ex.ToString());
}
}
