apache 2.2.6 nlb to apache tomcat 5.5 on EMC documentum

[Omer Yfhar]

Hello all

I have a big envirument of 5 win2003.

each server hold one apache and 4 apache tomcat instanc.

There are a lot of mess going on becuse no one knew how to impliment them. they are all in the LAN so security isnt an issu.

i saw they are configure to act with proxy + jk

 

in httpd.conf:

 

<Proxy balancer://mycluster>

  BalancerMember ajp://localhost:8009 route=jvm1 retry=5

  BalancerMember ajp://localhost:8109 route=jvm2 retry=5

  BalancerMember ajp://localhost:8209 route=jvm3 retry=5

  BalancerMember ajp://localhost:8309 route=jvm4 retry=5

</Proxy>

 

 

<Location /webtop/>

Proxypass balancer://mycluster/webtop/ stickysession=JSESSIONID|jsessionid

</Location>

 

 

<Location /whoami/>

Proxypass balancer://mycluster/whoami/ stickysession=JSESSIONID|jsessionid

</Location>

 

in server.xml:

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->

    <Connector

port="8100"              maxHttpHeaderSize="8192"

              maxThreads="2000" minSpareThreads="25" maxSpareThreads="75"

              enableLookups="false" redirectPort="8443" acceptCount="1000"

              connectionTimeout="60000" maxKeepAliveRequests="1000" disableUploadTimeout="true" />

    <!-- Note : To disable connection timeouts, set connectionTimeout value

    to 0 -->

 

<!-- Note : To use gzip compression you could set the following properties :

 

  compression="on"

  compressionMinSize="2048"

  noCompressionUserAgents="gozilla, traviata"

  compressableMimeType="text/html,text/xml"

-->

 

    <!-- Define a SSL HTTP/1.1 Connector on port 8443 -->

    <!--

    <Connector port="8443" maxHttpHeaderSize="8192"

              maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

              enableLookups="false" disableUploadTimeout="true"

              acceptCount="100" scheme="https" secure="true"

              clientAuth="false" sslProtocol="TLS" />

    -->

 

    <!-- Define an AJP 1.3 Connector on port 8009 -->

    <Connector port="8009"

              enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

 

    <!-- Define a Proxied HTTP/1.1 Connector on port 8082 -->

    <!-- See proxy documentation for more information about using this. -->

    <!--

    <Connector port="8082"

              maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

              enableLookups="false" acceptCount="100" connectionTimeout="20000"

              proxyPort="80" disableUploadTimeout="true" />

   

 

my Question, what is the best senario to implement apache NLB to serve apache tomcat.

 

thanks

You could just do it with DNS round robin.

 

Have both ips resolve to the one hostname.
