David,
Here are notes on running under Tomcat 6...
First, untar Tomcat somewhere.
Now you can run tomcat either directly from the binary directories, or
relocate the CATALINA_BASE and run it elsewhere sharing the binaries
(good for multiple instances).
If running Tomcat, as-is out of the binary directories:
- modify ./conf/server.xml to adjust any ports otherwise run on
default 8080 with shutdown port 8005
- copy the solr*.war file to ./webapps while renaming to solr.war if
it isn't already called that in your build.
- create a startup script that looks something like the following:
export JAVA_OPTS="$JAVA_OPTS
-Dsolr.solr.home=/place/where/my/solr/conf/dir/is
-Dsolr.data.dir=/place/where/my/index/dir/is -Xms256m -Xmx800m"
exec ./tomcat-current/bin/startup.sh
Adjusting the memory settings how you like, and set solr.solr.home to
the folder containing your conf directory (but not directly to the
conf directory, it should be one level up). The solr.data.dir will
point to a directory that will contain the index directory (but not
the index directory itself, it should be one level up).
So for a tree that looks like:
/search
./conf (copy all Solr config files here including XSL
directories or link to those)
./index (omit this directory and let Solr create it for you, or
copy in a valid index to this directory)
You can run Tomcat with:
export JAVA_OPTS="$JAVA_OPTS -Dsolr.solr.home=/search
-Dsolr.data.dir=/search -Xms256m -Xmx800m"
exec ./tomcat-current/bin/startup.sh
If you wish to run Tomcat outside of the binary directory, and
possibly multiple instances, use a structure such as:
/search
shared
solr
conf (copy solr/conf for your configuration here)
instance1
solr
conf -> ../../../shared/solr/conf
index
tomcat
conf (contents copied from tomcat/conf)
logs (empty initially)
temp (empty initially)
webapps (only include solr.war and other files from
tomcat/webapps that you wish to keep)
work (empty initially)
For this, your Tomcat startup would be:
export JAVA_OPTS="$JAVA_OPTS -Dsolr.solr.home=/search/instance1/solr
-Dsolr.data.dir=/search/instance1/solr -Xms256m -Xmx1000m"
export CATALINA_BASE=/search/instance/tomcat
exec ./tomcat-current/bin/startup.sh
A few tricks to keep in mind:
Use symbolic links to share things, for example if you have a file in
your tomcat config that will be identical to the base installed
tomcat's version and same for all instances, just link to it rather
than copying it. The same for the webapps directory, don't copy if
you can link.
