springcloud Eureka Server Cluster Setup

Create a springboot project pom.xml file as follows

4.0.0

<groupId>com</groupId>
<artifactId>eureka-server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>eureka-server</name>
<description>Demo project for Spring Boot</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3.RELEASE</version>
    <relativePath/>
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        <version>2.0.3.RELEASE</version>
    </dependency>
</dependencies>


<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.0.3.RELEASE</version>
        </plugin>

</build>

On startup class annotate @EnableEurekaServer modify the configuration file as follows

Here peer1 and peer2

Modify the host file, and then add on the line, the equivalent server address

Then to the root directory of the project into cmd execute mvn clean package this time will appear in the target directory of the project a jar

And then proceeds to enter the target directory cmd Run java -jar eureka-server-0.0.1-SNAPASHOT.jar --spring.profiles.active = peer1 then command to open a window, also enter cmd in the target directory, execute command java -jar eureka-server-0.0.1-SNAPASHOT.jar --spring.profiles.active = peer2 this point your browser to localhost: 8760 and localhost: 8761 on it

Then create two springboot project is almost the same, is to visit the port has changed as follows pom.xml

4.0.0

<groupId>com</groupId>
<artifactId>eureka-client</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>eureka-client</name>

Plus @EnableEurekaClient comment on the boot and then configure the following types of documents

Is not the same as the port number and then start two projects, you can find two items are registered to the 8760 and 8761 above, and in the two projects are coupled with this method, after testing easy

Finally, create a boot project to test the pom.xml as follows

4.0.0 com eureka-client-1 0.0.1-SNAPSHOT eureka-client-1 Demo project for Spring Boot

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3.RELEASE</version>

Start classes are as follows

In a new controller

Profiles

And then start the five projects, the browser visit http: // localhost:? 8763 / test name = Joe Smith returned data will be requested address, refresh a few times you will find the requested service is not the same
