Ciao Justin,
Yesterday and today I did other tests on the clustering of Geoserver, I
found two solutions.
1. Tomcat cluster
Using the Tomcat clusterin you can use Geoserver on N nodes without session
replication. Earlier I had configured the N nodes to be distributions and
then I added in web.xml of every single node tag <distributable /> but this
for the problem of Serialization does not allow logging in the user
interface for Geoserver administration .
Commenting on the tag <distributable /> login works. Of course the session
is not replicated on all nodes. But you have HA on the nodes that are part
of the cluster. I Using a script when the configuration change and reloading
on all nodes the configuration.
2. Terracotta cluster
Talking to Simone, he advised "Terracotta Cluster," this application enables
you to build distributed sessions, I did some tests seem to work. The trick
is in the configuration file where you can indicate the classes that doesn't
work session replication.
tc-config.xml
...
<include>
<class-expression>org.acegisecurity.context.SecurityContextImpl</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.providers.anonymous.AnonymousAuthenticationToken</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.providers.AbstractAuthenticationToken</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.ui.WebAuthenticationDetails</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.GrantedAuthorityImpl</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.ui.savedrequest.SavedRequest</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.ui.savedrequest.SavedCookie</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.providers.UsernamePasswordAuthenticationToken</class-expression>
</include>
<include>
<class-expression>org.acegisecurity.userdetails.User</class-expression>
</include>
<include>
<class-expression>org.vfny.geoserver.global.UserContainer</class-expression>
</include>
...
I have tested this on 2 nodes on the same machiene, and the session was
replicated.
At the end of all my tests I would write an article on the Geoserver blog
-> "Geoserver Cluster"
Thanks Justin
