SpringCloud的入门学习之Netflix-eureka（Eureka的集群版搭建）

1、Eureka单机版的话，可能会出现单点故障，所以要保障Eureka的高可用，那么可以进行搭建Eureka的集群版。

　　高可用的Eureka的注册中心，将注册中心服务部署到多台物理节点上，形成一个集群，集群之间的多个节点需要相互通信的。那么如何搭建集群版的Eureka呢，每个实例都需要加载自己的配置文件，根据配置文件配置的信息与其他节点进行通信，使用springboot的多配置文件可以实现每个实例加载自己的配置文件。每个实例加载自己的配置文件的时候可以拿到其他节点的信息，这个时候每个节点就串联起来了。

2、使用springboot的多环境配置，来搭建Eureka的高可用集群式部署。由于使用的是maven构建的springboot项目，所以首先引入pom.xml配置文件，这里需要注意的是springboot的版本、springcloud的版本对应，不然会出现一个版本不对应错误，稍后可以贴一下错误。我使用的springboot版本是2.2.0的，springcloud版本是Hoxton.RC1。

在搭建Eureka集群时，需要添加多个配置文件，并且使用 SpringBoot 的多环境配置方式。集群中需要多少节点就添加多少个配置文件。修改配置文件application-eureka1.properties。内容如下所示：

 # 配置项目名称
 spring.application.name=springcloud-eureka-server-ha

 # 配置端口号
 spring.port=

 # 是否将自己注册到 Eureka-Server 中，默认的为 true。eureka集群版可以加也可以不加此配置的。
 # 集群版的时候，可以注册到其他节点，但是单机版不能注册到自己的。
 eureka.client.registerWithEureka=false

 # 是否从 Eureka-Server 中获取服务注册信息，默认为 true。eureka集群版可以加也可以不加此配置的。
 eureka.client.fetchRegistry=false

 # 设置 eureka 实例名称，与配置文件的变量为主。
 # 在搭建 Eureka 集群时，需要添加多个配置文件，并且使用 SpringBoot 的多环境配置方式。
 # 集群中需要多少节点就添加多少个配置文件。
 eureka.instance.hostname=eureka1

 #设置服务注册中心地址，指向另一个注册中心。
 eureka.client.serviceUrl.defaultZone=http://eureka2:/eureka/

配置application-eureka2.properties配置文件，内容如下所示：

 # 配置项目名称
 spring.application.name=springcloud-eureka-server-ha

 # 配置端口号
 spring.port=

 # 是否将自己注册到 Eureka-Server 中，默认的为 true。eureka集群版可以加也可以不加此配置的。
 eureka.client.registerWithEureka=false

 # 是否从 Eureka-Server 中获取服务注册信息，默认为 true。eureka集群版可以加也可以不加此配置的。
 eureka.client.fetchRegistry=false

 #设置 eureka 实例名称，与配置文件的变量为主 。
 eureka.instance.hostname=eureka2

 #设置服务注册中心地址，指向另一个注册中心。
 eureka.client.serviceUrl.defaultZone=http://eureka1:8761/eureka/

配置日志管理，logback 日志配置文件。你可以选择使用配置文件或者使用配置的方式，内容如下所示：

 <?xml version="1.0" encoding="UTF-8" ?>
 <configuration>
     <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径 -->
     <property name="LOG_HOME" value="${catalina.base}/logs/" />
     <!-- 控制台输出 -->
     <appender name="Stdout"
         class="ch.qos.logback.core.ConsoleAppender">
         <!-- 日志输出编码 -->
         <layout class="ch.qos.logback.classic.PatternLayout">
             <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
             <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{} -
                 %msg%n
             </pattern>
         </layout>
     </appender>
     <!-- 按照每天生成日志文件 -->
     <appender name="RollingFile"
         class="ch.qos.logback.core.rolling.RollingFileAppender">
         <rollingPolicy
             class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
             <!--日志文件输出的文件名 -->
             <FileNamePattern>${LOG_HOME}/server.%d{yyyy-MM-dd}.log
             </FileNamePattern>
             <MaxHistory></MaxHistory>
         </rollingPolicy>
         <layout class="ch.qos.logback.classic.PatternLayout">
             <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
             <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{} -
                 %msg%n
             </pattern>
         </layout>
         <!--日志文件最大的大小 -->
         <triggeringPolicy
             class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
             <MaxFileSize>10MB</MaxFileSize>
         </triggeringPolicy>
     </appender>

     <!-- 日志输出级别 -->
     <root level="DEBUG">
         <appender-ref ref="Stdout" />
         <appender-ref ref="RollingFile" />
     </root>

 </configuration>

3、Eureka的集群部署，需要的部署环境是安装jdk1.8，需要配置好环境变量哦，不需要安装tomcat，因为使用的springboot开发的，其内置了tomcat，将打好的jar包传到服务器使用命令就可以运行了。由于使用的maven构建的项目，所以这里将使用maven install进行项目的打包。

注意：需要关闭自己的防火墙哈，或者开发你指定的端口号，我这里为了方便直接关闭防火墙了。

如果打包部署，遇到如下所示错误，可以按照此解决方法进行问题的解决。

 [WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

鼠标右击项目，properties，找到maven------>删除pom.xml，Apply即可，如下图。

上面操作完毕，如果你再次maven install还是失败的话，就update project，再次maven install应该就可以了。打包的项目如下所示。

将打好包的项目传到服务器上面，进行部署测试。如下所示：

在/usr/local/创建一个eureka 的目录，将项目的jar包拷贝到/usr/local/eureka。

 [root@slaver4 package]# ls
 elasticsearch-5.4..tar.gz           haproxy-1.6..tar.gz      node-v8.16.2-linux-x64.tar.xz               rabbitmq-server-3.6.-.noarch.rpm
 erlang-18.3-.el7.centos.x86_64.rpm  keepalived-1.2..tar.gz  phantomjs-2.1.-linux-x86_64.tar.bz2        socat-1.7.3.2-1.1.el7.x86_64.rpm
 es-sql-site-standalone.zip           master.zip                rabbitmq_delayed_message_exchange-0.0..ez  springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar
 [root@slaver4 package]# cd /usr/local/
 [root@slaver4 local]# ls
 bin  etc  games  include  lib  lib64  libexec  nginx  package  sbin  share  soft  src
 [root@slaver4 local]# mkdir eureka
 [root@slaver4 local]# cd eureka/
 [root@slaver4 eureka]# ls
 [root@slaver4 eureka]# cp /home/hadoop/package/springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar .
 [root@slaver4 eureka]# ls
 springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar
 [root@slaver4 eureka]#

你可以使用启动脚本文件进行项目的启动，vim server.sh，我使用的如下所示：

 #!/bin/bash

 cd `dirname $`

 CUR_SHELL_DIR=`pwd`
 CUR_SHELL_NAME=`basename ${BASH_SOURCE}`

 # 修改点1，修改成自己的项目名称。
 JAR_NAME="springcloud-eureka-server-ha-0.0.1-SNAPSHOT.jar"
 JAR_PATH=$CUR_SHELL_DIR/$JAR_NAME

 #JAVA_MEM_OPTS=" -server -Xms1024m -Xmx1024m -XX:PermSize=128m"
 JAVA_MEM_OPTS=""

 # 修改点2，修改成自己的配置文件变量名称。
 SPRING_PROFILES_ACTIV="-Dspring.profiles.active=eureka1"
 #SPRING_PROFILES_ACTIV=""
 LOG_DIR=$CUR_SHELL_DIR/logs
 LOG_PATH=$LOG_DIR/${JAR_NAME%..log

 echo_help()
 {
     echo -e "syntax: sh $CUR_SHELL_NAME start|stop"
 }

 if [ -z $ ];then
     echo_help
     exit
 fi

 if [ ! -d "$LOG_DIR" ];then
     mkdir "$LOG_DIR"
 fi

 if [ ! -f "$LOG_PATH" ];then
     touch "$LOG_DIR"
 fi

 if [ "$1" == "start" ];then

     # check server
     PIDS=`ps --no-heading -C java -f --width  | grep $JAR_NAME | awk '{print $2}'`
     if [ -n "$PIDS" ]; then
         echo -e "ERROR: The $JAR_NAME already started and the PID is ${PIDS}."
         exit
     fi

     echo "Starting the $JAR_NAME..."

     # start
     nohup java $JAVA_MEM_OPTS -jar $SPRING_PROFILES_ACTIV $JAR_PATH >> $LOG_PATH >& &

     COUNT=
     while [ $COUNT -lt  ]; do
         sleep
         COUNT=`ps  --no-heading -C java -f --width  | grep "$JAR_NAME" | awk '{print $2}' | wc -l`
         if [ $COUNT -gt  ]; then
             break
         fi
     done
     PIDS=`ps  --no-heading -C java -f --width  | grep "$JAR_NAME" | awk '{print $2}'`
     echo "${JAR_NAME} Started and the PID is ${PIDS}."
     echo "You can check the log file in ${LOG_PATH} for details."

 elif [ "$1" == "stop" ];then

     PIDS=`ps --no-heading -C java -f --width  | grep $JAR_NAME | awk '{print $2}'`
     if [ -z "$PIDS" ]; then
         echo "ERROR:The $JAR_NAME does not started!"
         exit
     fi

     echo -e "Stopping the $JAR_NAME..."

     for PID in $PIDS; do
         kill $PID > /dev/null >&
     done

     COUNT=
     while [ $COUNT -lt  ]; do
         sleep
         COUNT=
         for PID in $PIDS ; do
             PID_EXIST=`ps --no-heading -p $PID`
             if [ -n "$PID_EXIST" ]; then
                 COUNT=
                 break
             fi
         done
     done

     echo -e "${JAR_NAME} Stopped and the PID is ${PIDS}."
 else
     echo_help
     exit
 fi

配置好如上所示脚本内容，记得将执行权限给server.sh启动脚本。

 [root@slaver4 eureka]# chmod -R  server.sh
 [root@slaver4 eureka]# ll
 total
 -rwxr-xr-x.  root root      Nov  : server.sh
 -rw-r--r--.  root root  Nov  : springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar
 [root@slaver4 eureka]#

在第二台服务器上面，同样的操作搞一遍。这里就不进行演示了。

然后修改linux的host文件，由于项目里面是通过eureka.client.serviceUrl.defaultZone=http://eureka1:8761/eureka/来访问的，所以要对配置文件进行修改。如下所示：

注意：如果是两台或者多台机器的时候，由于eureka1需要访问eureka2，所以需要将eureka2对应的ip也要加进来的哦。同理，服务器1和服务器2都需要配置的。

 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::         localhost localhost.localdomain localhost6 localhost6.localdomain6

 192.168.110.133 eureka1
 192.168.110.134 eureka2

启动2个服务器的eureka注册中心，这里就演示一个了，停止是./server.sh stop，如下所示：

 [root@slaver4 eureka]# ./server.sh start
 Starting the springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar...
 springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar Started and the PID is .
 You can check the log file in /usr/local/eureka/logs/springcloud-eureka-server-ha-0.0.-SNAPSHOT.jar for details.
 [root@slaver4 eureka]#

通过浏览器访问注册中心的管理页面。你可以访问任意一台机器的。如下所示：

Eureka1机器访问如下所示：http://192.168.110.133:8761/

Eureka2机器访问如下所示：http://192.168.110.134:8761/

上图的红色报错，这里先不进行处理了。翻译如下所示：

如果如下两个配置不加的话，访问界面如下所示：

 # 是否将自己注册到 Eureka-Server 中，默认的为 true。eureka集群版可以加也可以不加此配置的。
 # 集群版的时候，可以注册到其他节点，但是单机版不能注册到自己的。
 eureka.client.registerWithEureka=false

 # 是否从 Eureka-Server 中获取服务注册信息，默认为 true。eureka集群版可以加也可以不加此配置的。
 eureka.client.fetchRegistry=false

Eureka1机器访问如下所示：http://192.168.110.133:8761/

Eureka2机器访问如下所示：http://192.168.110.133:8762/
