Problema do Tomcat Cluster Farm Deployer

Eu configurei o cluster apache-tomcat com mod_jk no servidor ubuntu. Eu tenho alguns problemas com FarmDeployer , que implanta arquivos de guerra para outros servidores da web no cluster e tenho algumas esperanças de que funcione como eu postei e tenho FarmDeployer trabalhando aqui .

O implantador de guerra funciona perfeitamente com a configuração abaixo do post, mas não funciona com confiança, pois às vezes dá erro 404 ao acessar a página:

 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

    <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
        <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                  address="192.168.1.4"
                  port="4000"
                  selectorTimeout="100"
                  maxThreads="6"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor">
                <Member className="org.apache.catalina.tribes.membership.StaticMember"
                      port="4000"
                      securePort="-1"
                      host="192.168.1.2"
                      domain="staging-cluster"
                      uniqueId="{0,1,2,3,4,5,6,7,8,9}"/>
            </Interceptor>
        </Channel>
        <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
            tempDir="/usr/share/tomcat/temp/"
            deployDir="/usr/share/tomcat/webapps/"
            watchDir="/usr/share/tomcat/watch/"
            watchEnabled="true"/>
    </Cluster>
  </Host>

A seguir, a configuração (de documentos do cluster do tomcat) que funciona perfeitamente para armazenamento em cluster HA e LB. But it fails in Farm Deployer e não há nenhum rastreio nos logs que explica porque o implantador do farm não está funcionando.

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

  <Manager className="org.apache.catalina.ha.session.DeltaManager" 

          expireSessionsOnShutdown="false"

          notifyListenersOnReplication="true"/>



  <Channel className="org.apache.catalina.tribes.group.GroupChannel">

    <Membership className="org.apache.catalina.tribes.membership.McastService" 

          address="228.0.0.4" 

          port="45564" frequency="500" 

          dropTime="3000"/>

    <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">

    </Sender>

    <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" 

           address="auto" port="4000" autoBind="100"

           selectorTimeout="5000" maxThreads="6"/>

    <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>

    <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>

  </Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>

<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

</Cluster>


<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
            tempDir="/usr/share/tomcat/temp/"
            deployDir="/usr/share/tomcat/webapps/"
            watchDir="/usr/share/tomcat/watch/"
            watchEnabled="true"/>


</Host>

Alguém tem alguma ideia ou qualquer configuração de trabalho sobre como fazer com que o implantador de farm funcione perfeitamente com o HA & Configuração LB?.

Obrigado!

Atualização: 1

Eu configurei com 3 nós conforme sua configuração e não consegui acessar o site com o nome de domínio (aponte para LB) e ele está dando a página tomcat ROOT mas com o ip/myapp que está renderizando.

O arquivo war myapp.war é implementado em todos os servidores, mas não é extraído em outros dois nós além do nó do gerenciador (servidor da web do implementador).

faz login em outros dois servidores da web :

Atualização: 2 para EDIT

ifconfig listou a entrada abaixo para eth0 em todos os servidores da web

UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1

Executou o comando abaixo em todos os servidores da web

route add -host 228.0.0.4 dev eth0

ping to 228.0.0.4 não funcionou em nenhum sistema

lsof -i: 4000 listado semelhante ao que está listado para você (não foi possível colar aqui como caracteres excedidos para esta postagem) no servidor da web do distribuidor (também em outros servidores):

MELHORIA : Felizmente usei a configuração Multicast alterando auto para ip em Receiver e vi myapp.war em outro servidor da web quando coloquei o arquivo war no diretório watch no servidor web do deployer. O problema é que war está apenas extraindo no servidor web do deployer (criando um direcotry), mas não em outros servidores.

How do I update for 3 web servers?

Faça o mesmo que ao fazer com 2 nós.

No nó de implantação, adicione mais um membro em StaticMembershipInterceptor :

<Member className="org.apache.catalina.tribes.membership.StaticMember"
                          port="4002"
                          securePort="-1"
                          host="192.168.5.208"
                          domain="staging-cluster"
                          uniqueId="{0,1,2,3,4,5,6,7,8,9}"/>

No nó 3, crie um cluster como o seguinte:

        <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
            <Channel className="org.apache.catalina.tribes.group.GroupChannel">
                <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="192.168.5.208"
                      port="4002"
                      selectorTimeout="100"
                      maxThreads="6"/>
            </Channel>
            <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                tempDir="/opt/tomcat6/tempdir/"
                deployDir="/opt/tomcat6/webapps/"
                watchDir="/opt/tomcat6/watchdir/"
                watchEnabled="false"/>
        </Cluster>

E copie um arquivo * .war para o diretório watchdir no nó de implantação. As linhas abaixo aparecerão em catalina.out :

Verifique a pasta webapps no nó 3:

-rw-r--r--  1 root    root    19962865 Aug 17 14:08 cas.war
...

e o catalina.out :

INFO: Deploying web application archive cas.war

EDITAR

Invalid or unreadable WAR file : invalid CEN header (bad signature)

Parece que o arquivo WAR está corrompido ao implantar em dois outros nós. Quantas vezes isso acontece?

Isn't it possible making FarmDeployer work with multicast from tomcat cluster docs which works perfectly for me apart from FarmDeployer?

Eu percebi isso! O motivo é que você não adicionou uma rota multicast para sua interface de rede, portanto, a mensagem do cluster não pode ser enviada / recebida entre nós do Tomcat:

lsof -i :4000
COMMAND  PID   USER   FD   TYPE    DEVICE SIZE NODE NAME
java    9968 tomcat   37u  IPv6 121232775       TCP localhost:terabase (LISTEN)

Siga as etapas abaixo:

Certifique-se de que sua interface de rede esteja ativada para multicast:

UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1
Adicione uma rota multicast:

route add -host 228.0.0.4 dev bond1

(você deve alterar bond1 para a interface de rede que recebe a mensagem de cluster)

O teste com ping -c 4 228.0.0.4 não funcionou para mim. Então, eu baixei ferramenta de teste de multicast , executei e vi a resposta abaixo:

./bin/multicast-test.sh -local 192.168.5.149 -group 228.0.0.4:45564

Ou você pode verificar com lsof , netstat , ...

lsof -i :4000
COMMAND   PID   USER   FD   TYPE    DEVICE SIZE NODE NAME
java    11084 tomcat   37u  IPv6 121236631       TCP localhost:terabase (LISTEN)
java    11084 tomcat   59u  IPv6 121236830       TCP localhost:terabase->192.168.5.199:43519 (ESTABLISHED)
java    11084 tomcat   66u  IPv6 121236835       TCP localhost:55538->192.168.5.199:terabase (ESTABLISHED)
java    11084 tomcat   67u  IPv6 121236836       TCP localhost:55539->192.168.5.199:terabase (ESTABLISHED)

Você está pronto para configurar o cluster do Tomcat com multicast.

Ative a configuração de armazenamento em cluster igual à mencionada no documento, mas altere <Receiver endereço de "auto" para a interface especificada:

<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="192.168.5.149"
                      port="4000"
                      autoBind="100"
                      selectorTimeout="5000"
                      maxThreads="6"/>

Faça o mesmo para todos os nós no cluster para ver se funciona.

EDIT 2

IMPROVEMENT: I happily Used the Multicast configuration changing auto to ip in Receiver and I saw myapp.war on another web server when I placed the war file in watch directory on deployer web server. The Problem is, war is only extracting on the deployer web server(creating a direcotry) but not on other servers.

Isso significa que a conexão entre o nó de implantação e os outros nós é estabelecida. Você ainda recebeu o mesmo erro "Arquivo WAR inválido ou ilegível: cabeçalho CEN inválido (assinatura incorreta)" ? Everytime?

java.util.zip.ZipException: invalid END header (bad central directory offset)

De acordo com o bug 45851 , você deve atualizar sua versão do Tomcat (pelo menos 6.0. 19) e tente novamente. Estou usando a versão 6.0.29 e, como você pode ver, funciona bem.

It's needing tomcat restart on other web servers then it copies and extracts and the site is available with other-web-severs-ip/myapp but not with domain name(404 error). Where do you point the site domain name, I pointed the site domain name in the DNS to LB and created a virtual host in all the tomcat web servers with same domain name

Não . Parece que você não limpou completamente. Não há necessidade de criar host virtual em todos os nós do Tomcat.

Supondo que você tenha o servidor HTTP Apache e o Tomcat no nó 1, com o IP 192.168.1.101. Dois outros nós do Tomcat em 1.102, 1.103. jvmRoute correspondentes são: tomcat1, tomcat2, tomcat3.

O mod_jk.conf no servidor HTTP Apache:

LoadModule          jk_module modules/mod_jk.so

JkWorkersFile       /etc/httpd/conf/workers.properties
JkShmFile           /var/log/httpd/jk.shm

JkLogFile           /var/log/httpd/mod_jk.log
JkLogLevel          info
JkLogStampFormat    "[%a %b %d %H:%M:%S %Y] "

JkMount /myapp/*    cluster

O workers.properties é algo assim:

worker.list = cluster

worker.tomcat1.port=8009        
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1

worker.tomcat2.port=8009        
worker.tomcat2.host=192.168.1.102
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1

worker.tomcat3.port=8009        
worker.tomcat3.host=192.168.1.103
worker.tomcat3.type=ajp13
worker.tomcat3.lbfactor=1

worker.cluster.type=lb
worker.cluster.balance_workers=tomcat1,tomcat2,tomcat3
worker.cluster.sticky_session=1

Tente novamente.
