1.
I unzip geoserver in tomcat dir.
orkun@anonymised.com:/usr/local/tomcat/webapps$ ls
docs examples geoserver host-manager manager ROOT
2. I startup geoserver.
3. in my browser. I hit. http://localhost:8080/geoserver/
but I received this error message.
HTTP Status 404 - /geoserver/
description The requested resource (/geoserver/) is not available.
What might the possible reasons of this ?
You have to look into the tomcat logs. On Ubuntu platforms
for example the issue is related to the very strict security
restrictions that Tomcat package ships with (unlike the standard
apache download, which on the contrary has none).
