系统：centos6.4
redis下载：http://www.redis.cn/download.html
redis安装步骤：
上传源码包到/lamp
解压：tar -zxvf redis.tar.gz
cd redis
make //编译源码，初装的linux系统到这一步可能会报以下错误
    CC adlist.o
/bin/sh: cc: command not found
就需要装gcc
yum install gcc
安装完后需要删除redis文件，重新解压，因为在原文件make还是会报相同的错误
rm zxvf redis
解压：tar -zxvf redis.tar.gz
cd redis
make //编译源码
cd src
make install //安装程序
为了便于管理可以将redis.conf redis-server redis-cli 这3个放入/usr/local/redis/目录下
最后进入redis.conf
修改 daemonize no 为daemonize yes #后台运行
到此redis 安装完成

6． 启动redis

a) $ cd /usr/local/bin

b) ./redis-server /etc/redis.conf

7． 检查是否启动成功

a) $ ps -ef | grep redis

关闭防火墙  systemctl stop firewalld.service 

3.   简单的Redis测试程序

    读者可以自行创建Eclipse项目，引入jedis的客户端包，测试程序如下：

    

public class RedisTest {

    private Jedis jedis = null;
    private String key1 = "key1";
    private String key2 = "key2";

    public RedisTest() {
        jedis = new Jedis("localhost");
    }

    public static void main(String[] args) {
        RedisTest redisTest = new RedisTest();
        redisTest.isReachable();
        redisTest.testData();
        redisTest.delData();
        redisTest.testExpire();
    }

    public boolean isReachable() {
        boolean isReached = true;
        try {
            jedis.connect();
            jedis.ping();
            // jedis.quit();
        } catch (JedisConnectionException e) {
            e.printStackTrace();
            isReached = false;
        }

        System.out
                .println("The current Redis Server is Reachable:" + isReached);
        return isReached;
    }

    public void testData() {
        jedis.set("key1", "data1");

        System.out.println("Check status of data existing:"
                + jedis.exists(key1));
        System.out.println("Get Data key1:" + jedis.get("key1"));

        long s = jedis.sadd(key2, "data2");
        System.out.println("Add key2 Data:" + jedis.scard(key2)
                + " with status " + s);
    }

    public void delData() {
        long count = jedis.del(key1);

        System.out.println("Get Data Key1 after it is deleted:"
                + jedis.get(key1));
    }

    public void testExpire() {
        long count = jedis.expire(key2, 5);

        try {
            Thread.currentThread().sleep(6000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        if (jedis.exists(key2)) {
            System.out
                    .println("Get Key2 in Expire Action:" + jedis.scard(key2));
        } else {
            System.out.println("Key2 is expired with value:"
                    + jedis.scard(key2));
        }
    }

}
