本文详细介绍了Redis的安装步骤，包括下载、编译、配置及服务启动过程。同时，提供了基于Dubbo框架的服务发布示例，涵盖服务接口定义、实现、Spring配置及服务启动流程。

一、redis安装

1、redis官网地址：http://redis.io/

2、redis下载：

wget http://download.redis.io/releases/redis-3.0.6.tar.gz

3、redis安装

解压 redis-3.0.6.tar.gz ，并进入解压目录

tar -zxvf redis-3.0.6.tar.gz

cd redis-3.0.6

编译安装。指定redis安装目录为/usr/local/redis

make PREFIX=/usr/local/redis install

mkdir run conf

cp /usr/local/src/redis-3.0.6/redis.conf /usr/local/redis/conf/

编辑配置文件redis.conf

服务自启动的配置

cp /usr/local/src/redis-3.0.6/utils/redis_init_script /etc/rc.d/init.d/redis

注册服务

chkconfig --add redis

以服务方式启动redis

service redis start/stop

将redis所生成命令加入到PATH中

echo "export PATH=/usr/local/redis/bin:$PATH">>/etc/profile

source /etc/profile

测试redis

[root@192 conf]# redis-cli
127.0.0.1:6379> keys *
(empty list or set)

二、dubbo 的demo编写

1、新建一个简单的maven工程，pom文件如下：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.5.3</version>
</dependency>

2、建立服务类

接口文件：

package com.xiaoqiang.dubbotest.demo1.service;
public interface IMyService {

public String hello(String name);
}

服务实现类:

package com.xiaoqiang.dubbotest.demo1.service.impl;
import org.springframework.stereotype.Component;
import com.xiaoqiang.dubbotest.demo1.service.IMyService;
@Component("myServiceImpl")
public class MyServiceImpl implements IMyService {

@Override
    public String hello(String name) {
        return "hello"+name;
    }
}

3、配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">


<context:component-scan base-package="com.xiaoqiang.dubbotest.demo1.service.*" />


<dubbo:application name="ws-demo" />


<dubbo:registry address="redis://192.168.0.108:6379" />


<dubbo:protocol name="dubbo" port="20880" />

<dubbo:service interface="com.xiaoqiang.dubbotest.demo1.service.IMyService" ref="myServiceImpl"/>
</beans>

4、服务启动类

package com.xiaoqiang.dubbotest.demo1.server;
import org.apache.log4j.BasicConfigurator;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ServerBootstrap {

static {

BasicConfigurator.configure();

}

public static void main(String[] args) throws Exception {
    final Object obj = new Object();
        ClassPathXmlApplicationContext cp = new ClassPathXmlApplicationContext(
        new String[] { "com/xiaoqiang/dubbotest/demo1/server/application-service.xml" });
        synchronized (obj) {
            obj.wait();
        }
    }
}
