Vertx集群配置

vertx集群配置

1. pom文件中引入vertx-hazelcast jar

<dependency>
    <groupId>io.vertxgroupId>
    <artifactId>vertx-hazelcastartifactId>
    <version>${vertx-version}version>
dependency>

目前是3.3.3版本

2. resources内加入hazelcast的配置文件cluster.xml

默认vertx会去找vertx-hazelcast.jar内的default-cluster.xml

如果需要自定义配置文件，需要将其放在classpath下，并且命名为cluster.xml，即打成fat包后在主目录下面。

eclipse的java项目只需将default-cluster.xml文件copy一份到resources目录内，并修改名字为cluster.xml，打包的时候就会打到classpath的主目录下。

3. cluster.xml配置

hazelcast的集群有3种方式

1. 广播multicast模式

<multicast enabled="true">
  <multicast-group>224.2.2.3multicast-group>
  <multicast-port>54327multicast-port>
multicast>

如果为true，同一个网段内的vertx实例会自动发现，并集群
2. ip地址tcp-ip模式

<tcp-ip enabled="true">
  <interface>192.168.1.28interface>
  <interface>192.168.1.27interface>
  <interface>192.168.1.26interface>
tcp-ip>

需要把要集群的ip地址列在这里
3. aws亚马逊云集群模式

<aws enabled="false">
  <access-key>my-access-keyaccess-key>
  <secret-key>my-secret-keysecret-key>
  
  <region>us-west-1region>
  
  <host-header>ec2.amazonaws.comhost-header>
  
  <security-group-name>hazelcast-sgsecurity-group-name>
  <tag-key>typetag-key>
  <tag-value>hz-nodestag-value>
aws>

一般采用第二种ip地址tcp-ip模式，将其它模式置为false。整体的cluster.xml文件：

<hazelcast xsi:schemaLocation="http://www.hazelcast.com/schema/config hazelcast-config-3.2.xsd"
           xmlns="http://www.hazelcast.com/schema/config"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

4. 集群方式运行fat.jar包

java -jar F:\work\i5xwxpro\target\i5xwxpro.jar -cluster

分别在对应的服务器上执行命令即可。

-cluster即是代表集群方式启动

5. nginx负载均衡

    upstream web{
        server 192.168.1.28:8080;
        server 192.168.1.27:8080;
        server 192.168.1.26:8080;
    }

nginx将请求负载到不同的vertx服务器即可
