# Spring cloud server 单机集群配置 #

以下按部署两套server为例进行配置；  
首先要在本机上修改/etc/hosts文件，添加两个hostname配置；  
如

> 10.3.3.132 server1  
> 10.3.3.132 server2

下面会用到这两个配置

## server1的application.properties配置 ##

请注意以下两处的配置：  
这里配置是的另一个server实例的地址

> eureka.client.serviceUrl.defaultZone=[http://dmcpxy:dmcpxy@server2:18761/eureka/][http_dmcpxy_dmcpxy_server2_18761_eureka]

这里配置的是当前实例使用的hostname，当在单机上部署服务注册中心集群时，这里不能使用$\{spring.cloud.client.ipAddress\}，否则会有冲突。而是要指定具体的一个不能重复的名字，如：

> eureka.instance.hostname=server1

#for spring cloud server
    spring.application.name=dmcpxy-cloud-server
    server.port=18761
    server.address=0.0.0.0
    eureka.client.serviceUrl.defaultZone=http://test:test@server2:18762/eureka/
    
    eureka.instance.prefer-ip-address=true
    
    eureka.server.enable-self-preservation=true
    eureka.server.eviction-interval-timer-in-ms=30000
    
    eureka.instance.lease-expiration-duration-in-seconds=30
    
    
    eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port}
    eureka.instance.hostname=server1
    
    
    security.basic.enabled=true
    security.user.name=test
    security.user.password=test
    
    eureka.client.registerWithEureka=false
    eureka.client.fetchRegistry=false
    ########################################################
    endpoints.shutdown.enabled=true
    endpoints.shutdown.sensitive=false
    endpoints.shutdown.path=/admin/shutdown
    management.security.enabled=false
    management.port=15151
    management.address=127.0.0.1
    ########################################################

## server2的application.properties配置 ##

#for spring cloud server
    spring.application.name=dmcpxy-cloud-server
    server.port=18762
    server.address=0.0.0.0
    eureka.client.serviceUrl.defaultZone=http://test:test@server1:18761/eureka/
    
    eureka.instance.prefer-ip-address=true
    
    eureka.server.enable-self-preservation=true
    eureka.server.eviction-interval-timer-in-ms=30000
    
    eureka.instance.lease-expiration-duration-in-seconds=30
    
    
    eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port}
    eureka.instance.hostname=server2
    
    
    security.basic.enabled=true
    security.user.name=test
    security.user.password=test
    
    eureka.client.registerWithEureka=false
    eureka.client.fetchRegistry=false
    ########################################################
