Dubbo高级篇_03_Redis的安装与使用

IP:192.168.1.121

环境:CentOS6.6

Redis版本:redis-3.0

安装目录:/usr/local/redis

1.编译和安装所需的包:



2.上传redis3安装包，解压



创建安装目录

[root@yxq src]# mkdir /usr/local/redis

解压



3.安装

(使用PREFIX指定安装目录):



安装完成后，可以看到/usr/local/redis 目录下有一个 bin 目录，bin 目录里就是 redis 的命令脚本：



4.将 Redis 配置成服务：

Redis 的启动脚本为：/usr/local/src/redis3.0/utils/redis_init_script

将启动脚本复制到/etc/rc.d/init.d/目录下，并命名为 redis



编辑/etc/rc.d/init.d/redis，修改相应配置，使之能注册成为服务：



配置文件设置：

创建 redis 配置文件目录



以上配置操作完成后，便可将 Redis 注册成为服务：



防火墙中打开对应的端口



修改 redis 配置文件设置：

将daemonize no 改为> daemonize yes，改为yes作为后台进程使用，

pidfile /var/run/redis.pid 改为> pidfile /var/run/redis_6379.pid

设置为no，pid文件是不会生成,stop等命令就不会生效,/etc/rc.d/init.d

会报如下错误:

/var/run/redis_6379.pid does not exist, process is not running

启动 Redis 服务



将 Redis 添加到环境变量中：



停止服务



默认情况下，Redis开启安全认证，可以通过/usr/local/redis/conf/6379.conf的requirepass指定一个验证密码



使用RedisDesktopManager登录管理

不输入验证密码



输入验证密码，测试连接



客户端使用console



Jedis的使用

public class RedisTest {
private static final Log log = LogFactory.getLog(RedisTest.class);

public static void main(String[] args) {

Jedis jedis = new Jedis("192.168.1.121");
jedis.auth("yxq123456");
String key = "redis";
String value = "";

jedis.del(key); // 删数据

jedis.set(key, "YiXiaoqun"); // 存数据
value = jedis.get(key); // 取数据
log.info(key + "=" + value);

jedis.set(key, "YiXiaoqun2"); // 存数据
value = jedis.get(key); // 取数据
log.info(key + "=" + value);

//jedis.del(key); // 删数据
//value = jedis.get(key); // 取数据
//log.info(key + "=" + value);
}
}

Jedis连接池的使用,这里设置redis不使用密码验证
