### 在linux上部署SpringCloudEureka的集群服务端 ###

项目打包

上传实例

启动脚本文件

修改hosts文件

启动eureka 注册中心

### 项目打包 ###

首先做好Eureka联机服务端配置,将maven项目install打成jar包(如eureka-1.0-SNAPSHOT.jar).  
![在这里插入图片描述][20190617142716320.png]

### 上传实例 ###

准备创建两个节点的集群,因此需要准备两个虚拟机,ip分别分192.168.110.129/192.168.110.130  
![在这里插入图片描述][20190617143147432.png]  
将jar包分别上传至这两个虚拟机中.

然后在/usr/local/创建一个eureka 的目录  
将项目的jar 包拷贝到/usr/local/eureka

### 启动脚本文件 ###

在两台虚拟机中都要创建启动脚本文件.

在/usr/local/eureka 目录下输入命令

vim  server.sh

创建启动脚本,内容如下(**注意有两处有中文的地方按实际修改-项目名/配置文件变量名称**)

#!/bin/bash
     
    cd `dirname $0`
     
    CUR_SHELL_DIR=`pwd`
    CUR_SHELL_NAME=`basename ${BASH_SOURCE}`
     
    JAR_NAME="项目名(如eureka-1.0-SNAPSHOT.jar)"
    JAR_PATH=$CUR_SHELL_DIR/$JAR_NAME
     
    #JAVA_MEM_OPTS=" -server -Xms1024m -Xmx1024m -XX:PermSize=128m"
    JAVA_MEM_OPTS=""
     
    SPRING_PROFILES_ACTIV="-Dspring.profiles.active=配置文件变量名称(如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 $1 ];then
        echo_help
        exit 1
    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 1000 | grep $JAR_NAME | awk '{print $2}'`
        if [ -n "$PIDS" ]; then
            echo -e "ERROR: The $JAR_NAME already started and the PID is ${PIDS}."
            exit 1
        fi
     
        echo "Starting the $JAR_NAME..."
     
        # start
        nohup java $JAVA_MEM_OPTS -jar $SPRING_PROFILES_ACTIV $JAR_PATH >> $LOG_PATH 2>&1 &
     
        COUNT=0
        while [ $COUNT -lt 1 ]; do
            sleep 1
            COUNT=`ps  --no-heading -C java -f --width 1000 | grep "$JAR_NAME" | awk '{print $2}' | wc -l`
            if [ $COUNT -gt 0 ]; then
                break
            fi
        done
        PIDS=`ps  --no-heading -C java -f --width 1000 | grep "$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 1000 | grep $JAR_NAME | awk '{print $2}'`
        if [ -z "$PIDS" ]; then
            echo "ERROR:The $JAR_NAME does not started!"
            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
                PID_EXIST=`ps --no-heading -p $PID`
                if [ -n "$PID_EXIST" ]; then
                    COUNT=0
                    break
                fi
            done
        done
     
        echo -e "${JAR_NAME} Stopped and the PID is ${PIDS}."
    else
        echo_help
        exit 1
    fi

赋予server.sh执行权限

chmod -R 755 server.sh

遇到下列报错说明sh编写的不对,打开检查一下即可(建议使用notepadd++的ftp插件复制)

./server.sh: line 88: unexpected EOF while looking for matching ``'
    ./server.sh: line 100: syntax error: unexpected end of file

### 修改hosts文件 ###

在两台虚拟机中都要修改hosts文件

vim /etc/hosts

在hosts文件最后加上

192.168.110.129 eureka1 
    192.168.110.130 eureka2

![在这里插入图片描述][20190617145538665.png]

### 启动eureka 注册中心 ###

在/usr/local/eureka目录下运行

./server.sh start  启动 
    ./server.sh stop  停止

**最后成功运行**
