Cluster Edition Eureka Server build

Each node in the cluster registry Eureka Server are equal, each node can act as a service, to vote between the service node by sending a heartbeat.

The project relies eurekaServer modify the stand-alone version of the content.

1. Create a new file application-eurekaserver1.properties

spring.application.name=eureka-server
server.port=8761

# Define named Eureka Server instances in the registration center. We recommend using the suffix defined in the configuration file.
eureka.instance.hostname=eurekaserver1
# Cluster configuration information other Eureka Server nodes. To configure a plurality of nodes, using a comma ',' a plurality of split node information.
# Node information format is: http: // address: port / eureka /. You can use the address IP, domain name, host name is defined.
# Using HTTP Basic syntax, provide a user name and password authentication security required for use.
# Syntax is: http: // username: password @ address: port / eureka /
eureka.client.serviceUrl.defaultZone=http://eurekaserver2:8761/eureka/

application-eurekaserver2.properties

spring.application.name=eureka-server
server.port=8761

# Define named Eureka Server instances in the registration center. We recommend using the suffix defined in the configuration file.
eureka.instance.hostname=eurekaserver1
# Cluster configuration information other Eureka Server nodes. To configure a plurality of nodes, using a comma ',' a plurality of split node information.
# Node information format is: http: // address: port / eureka /. You can use the address IP, domain name, host name is defined.
# Using HTTP Basic syntax, provide a user name and password authentication security required for use.
# Syntax is: http: // username: password @ address: port / eureka /
eureka.client.serviceUrl.defaultZone=http://eurekaserver2:8761/eureka/

2. Modify the host name, vi / etc / hosts

192.168.186.115 eurekaserver1
192.168.186.116 eurekaserver2

3. Use Maven install packaged jar, the target directory project, the two are uploaded to the server

4. In the same directory jar package upload new file, vi eurekaserver.sh, modifying the corresponding parameter

#!/bin/bash
 
cd `dirname $0`

#SPRING_PROFILES_ACTIV = "" 
LOG_DIR = $ CUR_SHELL_DIR / logs
LOG_PATH=$LOG_DIR/${JAR_NAME%..log

    while [ $COUNT -lt 1 ]; do

        COUNT=`ps  --no-heading -C java -f --width 1000 | grep "$JAR_NAME" | awk '{print $2}' | wc -l`
        if [ $COUNT -gt 0 ]; then
            break
        fi
    done

        exit 1
    fi
 
    echo -e "Stopping the $JAR_NAME..."
 
    for PID in $PIDS; do
        kill $PID > /dev/null 2>&1
    done
 
    COUNT=0
    while [ $COUNT -lt 1 ]; do
        sleep 1
        COUNT=1
        for PID in $PIDS ; do

            if [ -n "$PID_EXIST" ]; then
                COUNT=0
                break
            fi
        done
    done
 
    echo -e "${JAR_NAME} Stopped and the PID is ${PIDS}."
else
    echo_help
    exit 1
