Server farm management based on plugins
Hi, David:
According to jira https://issues.apache.org/jira/browse/GERONIMO-4284,
there should be a FarmComand.groovy file under
server/trunk/framework/modules/geronimo-commands/src/main/groovy/org/apache/geronimo/commands/FarmCommand.groovy<http://svn.apache.org/viewcvs.cgi//geronimo/server/trunk/framework/modules/geronimo-commands/src/main/groovy/org/apache/geronimo/commands/FarmCommand.groovy/?rev=693703&view=markup>,
which should implement deploy/farm, but from Geronimo 2.2 branch and
server trunk, this file is missing.
And also from doc
http://cwiki.apache.org/GMOxDOC22/plugin-based-farming.html, there should be
a GShell *deploy/farm* command to mange farm.But after i installed plugins
below,
org.apache.geronimo.configs/plugin-farm-datasource/2.2-SNAPSHOT/car<http://localhost:8080/console/portal//Services/Repository/__ac0x3console-base0x2RepositoryViewer%21604305819%7C0/__pm0x3console-base0x2RepositoryViewer%21604305819%7C0_view?res=org.apache.geronimo.configs%2Fplugin-farm-datasource%2F2.2-SNAPSHOT%2Fcar&action=usage&formId=-5661674799437896392>
org.apache.geronimo.configs/plugin-farm-member/2.2-SNAPSHOT/car<http://localhost:8080/console/portal//Services/Repository/__ac0x3console-base0x2RepositoryViewer%21604305819%7C0/__pm0x3console-base0x2RepositoryViewer%21604305819%7C0_view?res=org.apache.geronimo.configs%2Fplugin-farm-member%2F2.2-SNAPSHOT%2Fcar&action=usage&formId=-5661674799437896392>
org.apache.geronimo.configs/plugin-farm/2.2-SNAPSHOT/car<http://localhost:8080/console/portal//Services/Repository/__ac0x3console-base0x2RepositoryViewer%21604305819%7C0/__pm0x3console-base0x2RepositoryViewer%21604305819%7C0_view?res=org.apache.geronimo.configs%2Fplugin-farm%2F2.2-SNAPSHOT%2Fcar&action=usage&formId=-5661674799437896392>
i still can't find out this command via gshell command, just cluster/deploy
and cluster/heartmonitor.Can you give some hints?
And "Server farm management based on plugins" means install plugins to farm
members, but if we want to deploy applications (non-plugin forma) to farm
members, we still follow "Farming using
Deployment<http://cwiki.apache.org/GMOxDOC22/farming-using-deployment.html>"
article:
http://cwiki.apache.org/GMOxDOC22/farming-using-deployment.html, right?
Thanks.

this command turns into farm.removePluginFromPluginList, so this seems
like a bug.

this seems correct to me, a plugin list can exist even if it is not
associated with any clusters

I'd expect this to create records in cluster and pluginlist if they
are missing, and then insert into cluster_pluginlist.

I think you found some bugs :-)
Looking at the groovy ClusterCommand, I'd guess that we need some more
remove commands:
remove --cluster deletes a cluster from the cluster table after
removing any cluster_pluginlist records that refer to the cluster
remove --pluginlist deletes a pluginlist from the pluginlist table
after removing appropriate cluster_pluginlist and pluginlst_plugin
records
remove --pluginartifact deletes a plugin from the plugin table after
removing appropriate pluginlist_plugin records.
Does this make sense to you?
thanks

Re: Server farm management based on plugins
Posted by viola lu <vi...@gmail.com>.
Thanks. David.
I tried this function, and some details to confirm with you:
1.Farm Controller should install plugin-farm, plugin-farm-datasource
plugins , set its DefaultPluginRepository attribute in file
config-substitutions.properties as a share repository accessible by all farm
members.If farm members has no access authority to this share repository,
farm deploy will fail.
2.Every farm member should install plugin-farm-member plugin, set NodeName,
and ServerHostname=[NODE_IP] attributes in file
config-substitutions.properties.If ServerHostname is not set to its
corresponding IP, this farm node will not be added into this farm goup.Also
farm member should add share install plugin repository to its file
plugin-repositories.properties including access username and password like
http\://9.186.10.67
\:8080/plugin/maven-repo/=system\={Simple}rO0ABXNyABlqYXZheC5jcnlwdG8uU2VhbGVkT2JqZWN0PjY9psO3VHACAARbAA1lbmNvZGVkUGFyYW1zdAACW0JbABBlbmNyeXB0ZWRDb250ZW50cQB+AAFMAAlwYXJhbXNBbGd0ABJMamF2YS9sYW5nL1N0cmluZztMAAdzZWFsQWxncQB+AAJ4cHB1cgACW0Ks8xf4BghU4AIAAHhwAAAAEHnh03EmiNu4VTuWH+xZiRBwdAADQUVT
So that access passes.
3.After run cluster/deploy remove -l pluginlist1 -a **/hello/**, this will
remove the plugin from all farm members, but fail to delete the plugin
record from table PLUGINLIST_PLUGIN of PluginFarmDatatabase db on
controller node, this will result in duplicate(redundant) records in db,
and if i run cluster/deploy remove -c cluster1 -l pluginlist1, plugin list
will be removed from table PLUGINLIST_CLUSTER, but pluginlist1 is still kept
in table PLUGINLIST, when add a pluginlist to cluster, both tables are
updated meantime, so seems PluginFarmDatatabase can't keep integrity when
delete.
Thanks.

At some point the "farm" commands were renamed to "cluster". AFAIK
there are no gshell commands related to deployment based clustering
since you set that up with some special repositories in the server
that are then accessed using normal gshell commands.

I think you should first consider which farm technology better suits
your needs, then decide whether to pre-deploy your apps as plugins and
use the plugin based clustering or deploy your apps directly to a
deployment based cluster. I can't think of any good reasons to use
the deployment based cluster, but other people might be able to.
hope this is correct and helps
