Tigase8.0 源代码分析：四、集群配置篇

 Tigase8集群配置是很简单的，本文从实验的角度来了解tigase集群配置及启动。

首先你先能保证在机器上能跑单机版本的代码，如果还没有,先移步看前面的博客吧<IDEA 上 Tigase8.0 源代码编译运行>

1、准备工作：内网中至少两台主机：

我就以我本地实验来做参考：

主机A：[192.168.3.2] 主机名[llooper]

主机B：[192.168.3.5] 主机名[shirley-pc]

2、修改 C:WindowsSystem32driversetchosts 文件，配置名字映射使得A.B主机之间互通

192.168.3.5 Shirley-PC
192.168.3.2 llooper

3、修改Tigase的配置文件

A主机：

'admin = [ 'admin@llooper' ]
'cluster-mode' = true
'cluster-nodes' = [ 'llooper' , 'Shirley-PC' ]
'config-type' = 'default'
'default-virtual-host' = 'llooper'
'debug' = [ 'server', 'cluster','eventbus' ]
'cl-comp' {
    'connect-all' = true
}
dataSource {
  'pool-size' = 1
    default () {
        uri = 'jdbc:mysql://A数据源'
    }
}

B主机：

'admin = [ 'admin@Shirley-PC' ]
'cluster-mode' = true
'cluster-nodes' = [ 'llooper' , 'Shirley-PC' ]
'config-type' = 'default'
'default-virtual-host' = 'Shirley-PC'
'debug' = [ 'server', 'cluster','eventbus' ]
'cl-comp' {
    'connect-all' = true
}
dataSource {
  'pool-size' = 1
    default () {
        uri = 'jdbc:mysql://B数据源'
    }
}

 集群相关的配置也就以下三个属性需要注意下：

'cluster-mode' = true  //开启集群模式
'cluster-nodes' = [ 'llooper' , 'Shirley-PC' ] //集群全部的主机域名
'cl-comp' {
    'connect-all' = true  //动态地将不在集群配置中的节点加入到集群中，默认为false
}

4、注意：目前集群user模块数据库必需使用不同的数据源，如果同用一个数据库，不同域下的注册用户都在同一个user模块表中。通过vhost-manager在users表中，查询出UID，再通过vhosts-lists作为key在tig_pairs表中查询库加载<vhost>，如果都同用一个数据源，那么vhost包含所有域。当eventbus组件发出给另一个域的数据包在MessageRouter中查询vhost发现本地包含该域，所以导致数据包又投回来本机处理，从而出现数据包死循环的问题。

<vhost anon="true" tls-required="false" enabled="true" s2s-secret="15b43189-2b23-46ae-9dc6-ab0acdceafe5" hostname="llooper" max-users="0" register="true" domain-filter="ALL"><comps></comps><other></other></vhost>
<vhost anon="true" tls-required="false" enabled="true" s2s-secret="1434ac98-8ba1-41e2-a57e-6559fb94d921" hostname="shirley-pc" max-users="0" register="true" domain-filter="ALL"><comps></comps><other></other></vhost>

5、分别启动 XMPPServer ，成功运行服务！

6、使用PSI 进行测试：连接不同的域进行注册用户，然后进行互加好友，互发消息：

 

 A域和B域的账号互通消息，证明集群消息能相互转发成功！

7、最后，为了方便用户在调试Tigase代码，附上一件我修改过的配置。配置上，组件的线程数量被我修改为1. 为了串行执行，便于从日志中分析流程。

'admins' = [ 'admin@llooper' ]
'cluster-mode' = true
'cluster-nodes' = [ 'llooper' , 'Shirley-PC' ]
'config-type' = 'default'
'default-virtual-host' = 'llooper'
'debug' = [ 'server', 'cluster','eventbus' ]
'cl-comp' {
    'connect-all' = true
}

logging (class: tigase.conf.LoggingBean) {
    debug = [ 'server', 'cluster', 'eventbus' ]

    rootHandlers = [ 'java.util.logging.ConsoleHandler', 'java.util.logging.FileHandler' ]
    rootLevel = CONFIG
    'shutdown-thread-dump' = true
    handlers {
        'java.util.logging.ConsoleHandler' {
            formatter = 'tigase.util.log.LogFormatter'
             level = ALL
        }
        'java.util.logging.FileHandler' {
            append = true
            count = 1
            formatter = 'tigase.util.log.LogFormatter'
            level = ALL
            limit = 10000000
            pattern = 'logs/tigase.log'
        }
    }
 }
