1. Re: Cluster de WildFly não está funcionando
No JBoss EAP 6.1 eu alterava de:
<subsystem xmlns="urn:jboss:domain:web:1.2" default-virtual-server="default-host" native="false">
para:
<subsystem xmlns="urn:jboss:domain:web:1.2" default-virtual-server="default-host" instance-id="${jboss.server.name}" native="false">
Mas agora não tem mais esse subsystem... devo fazer algo relacionado a isso?

2. Re: Cluster de WildFly não está funcionando
Bom dia Adriano.
Você está usando o profile ha ou full-ha em seus server-groups?
Sua aplicação está configurada com <distributable/> ?
Abraços.

3. Re: Cluster de WildFly não está funcionando
Bom dia Eduardo, tudo bem?
Sim..
estou usando o full-ha...
e os dois wars q estou testando estão com <distributable/>.. um war já funcionou comigo num cluster de JBoss EAP e o outro é um exemplo da própria Red Hat..
Tava vendo as alterações no WildFly 8 mas de configuração que eu precise fazer não tem nada... Clustering Changes in WildFly 8
O que mais poderia ser?
Muito obrigado!

4. Re: Cluster de WildFly não está funcionando
Estranho.
Vamos lá:
- Consegue compartilhar os logs?
- O status das instancias /mod_cluster-manager estão ok ?
- Chegou a configurar os parametros no sysctl.conf:
# JBoss
net.core.rmem_max = 83886080
net.core.wmem_max = 83886080
net.core.rmem_default = 65536
net.core.wmem_default = 65536
Abraços.

5. Re: Cluster de WildFly não está funcionando
Opa, muito obrigado pela ajuda!
No mod_cluster_manager está tudo certo... aparecem os servers e as aplicações deployadas...
As aplicações estão funcionando.. só não estão replicando a sessão...
Vou configurar agora o sysctl.conf... isso eu não tinha feito... tem que fazer nos 3 WildFly? vou fazer aqui.. reiniciar as máquinas e testar novamente
Seguem abaixo os logs... se precisar de mais log é só falar...

mas o cluster continua não funcionando...

8. Re: Cluster de WildFly não está funcionando
Estranho mesmo.
As configurações de roteamento dos servidores estão ok? default gateway... etc etc..
Qual versão você está usando 8.2 ou 9.1 CR1?
Tenta fazer um teste com o pacote que o Arun Gupta fez: https://github.com/arun-gupta/wildfly-samples/tree/master/clustering/http
Abraços.

9. Re: Cluster de WildFly não está funcionando
então... tava pensando agora aqui..
minhas máquinas estão na nuvem.. em redes separadas... se o cluster funciona por multicast.. eu tenho que configurar alguma coisa pra elas se enxergarem...
talvez meu problema seja de rede mesmo... como vejo como está e como configuro?
tô usando o 8.2..
tava vendo o vídeo do Arun Gupta agora... vou fazer um teste.. mas acho q é algo de rede mesmo... tenho q configurar os slaves pra ficarem na mesma rede ou algo assim... o que você acha?
obrigadão!!

10. Re: Cluster de WildFly não está funcionando
deve ser isso... achei aqui como configurar uma rede privada no digital ocean... tô fazendo isso...
só não sei como devem ficar os jboss...
não sei se faço a rede pricada só pros slaves... e se altero os IPs deles pra 0.0.0.0...
ou se coloco todo mundo na rede privada e só o apache eu libero pra fora... talvez assim é a melhor forma...

12. Re: Cluster de WildFly não está funcionando
acho q entendi o q tenho que fazer..
tenho q configurar as 4 máquinas (httpd, master, slave1 e slave2) numa rede interna
colocar os -b e os jboss.domain.master.address com o IP interno
fazer o apache ser chamado pelo IP externo e redirecionar para IP interno... aí vai tá todo mundo interno e cluster vai funcionar...
acho q é isso.... ou não hahahah
mas infelizmente tá tarde e não vou conseguir testar agora...
amanhã na palestra vou mostrar na nuvem o load balancer funcionando... e o cluster vou mostrar na minha máquina subindo várias instâncias...
Eduardo, muitíssimo obrigado pela força! Ajudou muito!! Quero agradecer ao Maurício Magnani que me deu uma força via whatsapp e que me enviou um pdf que me fez compreender melhor o cenário como um todo também.
Esse grupo aqui é do caralho!! Obrigadão pessoal!
Vaaaleu!

13. Re: Cluster de WildFly não está funcionando
Opa Adriano.
Brother só uma dica:
Nunca deixe um Application Server exposto direto à internet, deixe somente a porta do front-end liberada (no caso seu Apache) e configure todo o fluxo de comunicação entre front-end e back-end (Apache x WildFly) via rede interna.
Sobre a camada do Application Server:
- Configure os hosts controllers (master/slave) para fazer bind somente na interface de rede interna. (ip interno)
- Verifique se os servidores estão com o mesmo multicast configurado.
- Outra opção:
Utilizar clustering em modo TCP ao inves de usar UDP, porém a configuração é bem chatinha.
Abraços e desculpe a demora no retorno.
Boa sorte na palestra!

14. Re: Cluster de WildFly não está funcionando
opa.. obrigado pela resposta!
sobre não deixar o AppServer exposto eu estou ciente.. esse é um ambiente de testes então fui bem flexível nesse ponto.. mas você está totalmente certo...
mas acho q o problema é mais embaixo.... tava falando com um amigo meu e ele comentou q na Amazon não é permitido broadcast/multicast.... e pesquisando encontrei que o digitalocean também não:
https://www.digitalocean.com/community/questions/ip-multicasting-on-private-networking
Então teria que encontrar outra forma para fazer isso (
