Tomcat -Virtual hosts and Access logging

Some times we may need to run multiple websites on single ip address with the same port number ,for example http( tcp-80 ) port .

If I have 2 websites called  www.example1.com and  www.example2.com pointing to same webserver 10.0.0.10,  then i will configure my tomcat webserver( 10.0.0.10 )following way .

Using vim editor i will  edit /tomcat_directory/conf/server.xml and add seperate  virtual host entries for each domain .

<Host name=”www.example1.com” debug=”0″ appBase=”example1″
unpackWARs=”true” autoDeploy=”true”
xmlValidation=”false” xmlNamespaceAware=”false”>
<Context path=”” docBase=”.”/>
<Logger className=”org.apache.catalina.logger.FileLogger”
directory=”logs” prefix=”localhost_log.” suffix=”.txt”
timestamp=”true”/>
<Valve className=”org.apache.catalina.valves.AccessLogValve” directory=”logs”

prefix=”localhost_access_log.” suffix=”.txt” pattern=”common” resolveHosts=”false”/>

<Host name=”www.example2.com” debug=”0″ appBase=”example2″
unpackWARs=”true” autoDeploy=”true”
xmlValidation=”false” xmlNamespaceAware=”false”>
<Context path=”” docBase=”.”/>
<Logger className=”org.apache.catalina.logger.FileLogger”
directory=”logs” prefix=”localhost_log.” suffix=”.txt”
timestamp=”true”/>
<Valve className=”org.apache.catalina.valves.AccessLogValve” directory=”logs”

prefix=”localhost_access_log.” suffix=”.txt” pattern=”common” resolveHosts=”false”/>

</Host>

</Engine>

</Service>

</Server>

example1 and example2  are root directories  where we  can copy webpages .

<Valve className=”org.apache.catalina.valves.AccessLogValve” directory=”logs”

prefix=”localhost_access_log.” suffix=”.txt” pattern=”common” resolveHosts=”false”/>  ……. this entry will log  website access logs  in /tomcat_directory/logs .
