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/bashcd `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%..logecho_help()
{echo -e "syntax: sh $CUR_SHELL_NAME start|stop"
}if [ -z $1 ];thenecho_helpexit 1

elseecho_helpexit 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
