Re: multiple las servers and apache virtual hosts

[Lynn deWitt <ldewitt@xxxxxxxxxxxxx>]

Hi Phil,
   I have about 9 LAS's running on two tomcat servers, and setting up a 
new one can be confusing.  I think the key point is that even though 
the LAS's are all in separate directories, the web interface files that 
are actually used all end up in the directory structure of the first 
LAS that that you set up that uses the tomcat server you're wanting to 
connect to.  I just set up a new LAS the other day so right now it's 
clear in my mind what happens - I'll try to outline it clearly:

Let's use your LAS A and LAS B example.  Let's say you have LAS A all 
set up and running under the default tomcat ports and it works fine, 
and now you want to set up LAS B using the same tomcat server as LAS A.

You have two directories where the LAS files were untarred into:    
/usr/local/las_A and /usr/local/las_B

Before configuring LAS B, you need to edit the file 
/usr/local/las_B/configure.pl to change the following line:

________
# Home of TOMCAT server

my $JAKARTA_HOME = "/usr/local/las_A/las_servlet/jakarta";
________

note that the JAKARTA_HOME for las_B needs to be in the las_A directory 
structure

cd to /usr/local/las_B and run configure.pl.   When it asks for the 
Tomcat ports, use the default or whatever you entered when you set up 
LAS A.

After running configure.pl, look in 
/usr/local/las_A/las_servlet/jakarta/webapps

You will now see directories and *.war files for both LAS's:

las_A.war
las_A (directory)
las_B.war
las_B (directory)

After configuring your apache server as directed by the configure 
script, you should now be able to access LAS_B using the same tomcat 
port as LAS_A  (ie http://.......:8080/las_B/servlets/dataset

Let me know if it still doesn't work.  Lynn
