redis

安装

tar -zxvf redis-3.2.5cd redis-3.2.5makemake installmake test

如果碰到安装问题

yum install gcc -y

make test碰到tcl问题

yum install tcl -y

启动

cd /usr/local/bin./redis-server

带配置启动

修改配置文件

启用后台进程

daemonize yes

1.关闭protected-mode模式，注释bind

protected-mode no#bind 127.0.0.1

2.开启protected-mode模式，配置bind及密码

protected-mode yesbind 主机名requirepass nozuonodie

验证

[root@h1 bin]# ./redis-cli -h 10.50.1.4110.50.1.41:6379> get foo(error) NOAUTH Authentication required.10.50.1.41:6379> auth nozuonodieOK10.50.1.41:6379> get foo"bar"10.50.1.41:6379> set foo ljkOK10.50.1.41:6379> get foo"ljk"10.50.1.41:6379> exit

程序验证

@SpringBootApplicationpublic class Application implements CommandLineRunner {    @Autowired    private  StringRedisTemplate stringRedisTemplate;    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }    @Override    public void run(String... strings) throws Exception {        String s = this.stringRedisTemplate.opsForValue().get("foo");        System.out.println(s);    }}打印结果为ljk

对象序列化验证

建立一个对象

public class User implements Serializable {    private static final long serialVersionUID = -892828255550795125L;    private String name;    private Integer age;    public User(String name, Integer age) {        this.name = name;        this.age = age;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }}

对象序列化接口

public class RedisObjectSerializer implements RedisSerializer<Object> {    private Converter<Object, byte[]> serializer = new SerializingConverter();    private Converter<byte[], Object> deserializer = new DeserializingConverter();    private static final byte[] EMPTY_ARRAY = new byte[0];    @Override    public byte[] serialize(Object o) throws SerializationException {        if (null == o) {            return EMPTY_ARRAY;        }        return serializer.convert(o);    }    @Override    public Object deserialize(byte[] bytes) throws SerializationException {        if (this.isEmpty(bytes)) {            return null;        }        return deserializer.convert(bytes);    }    private boolean isEmpty(byte[] data) {        return (data == null || data.length == 0);    }}

验证对象序列化是否成功

@SpringBootApplicationpublic class Application implements CommandLineRunner {//    @Autowired//    private  StringRedisTemplate stringRedisTemplate;    @Autowired    private RedisTemplate<String, User> redisTemplate;    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }    @Override    public void run(String... strings) throws Exception {        User u1 = new User("ljk", 18);        User u2 = new User("hwb", 3);        redisTemplate.opsForValue().set(u1.getName(), u1);        redisTemplate.opsForValue().set(u2.getName(), u2);        Integer age = redisTemplate.opsForValue().get("ljk").getAge();        System.out.println(age);//        String s = this.stringRedisTemplate.opsForValue().get("foo");//        System.out.println(s);    }}
