Redis 事務
例子1：
multi
OK
set book-name "java sixiang"
QUEUED
get book-name
QUEUED
sadd tag "java" "c++" "phchy" "php"
QUEUED
smembers tag
QUEUED
exec
1) OK
2) "java sixiang"
3) (integer) 4
4) 1) "java"
2) "phchy"
3) "php"
4) "c++"

例子2：
multi
OK
set a aaa
QUEUED
set b bbb
QUEUED
set c ccc
QUEUED
exec
1) OK
2) OK
3) OK
如果在 set b bbb 處失敗，set a 已成功不會回滾，set c 還會繼續執行。

Redis 指令碼

EVAL script numkeys key [key ...] arg [arg ...]
script 指令碼
numkeys數目
key key的值
arg 引數的值
EVAL "return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}" 2 key1 key2 first second
1) "key1"
2) "key2"
3) "first"
4) "second"

Redis 連線

AUTH "password"

PING
PONG

Redis 伺服器
INFO

Redis 安全

127.0.0.1:6379> CONFIG get requirepass
1) "requirepass"
2) ""
假如沒設定密碼執行auth foobared（密碼）
的話就會報
(error) ERR Client sent AUTH, but no password is set

預設情況下 requirepass 引數是空的，這就意味著你無需通過密碼驗證就可以連線到 redis 服務。
你可以通過以下命令來修改該引數：
127.0.0.1:6379> CONFIG set requirepass "runoob"
OK
127.0.0.1:6379> CONFIG get requirepass
1) "requirepass"
2) "runoob"

連線到 redis 服務
http://www.runoob.com/redis/redis-java.html
import redis.clients.jedis.Jedis;

public class RedisJava {
public static void main(String[] args) {
//連線本地的 Redis 服務
Jedis jedis = new Jedis("localhost");
System.out.println("連線成功");
//檢視服務是否執行
System.out.println("服務正在執行: "+jedis.ping());
}
}
