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).

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

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 

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
