一、事务
1、开启事务 multi
2、提交事务 exec
3、取消事务 discard
127.0.0.1:6379> multi OK 127.0.0.1:6379> set name devil QUEUED 127.0.0.1:6379> set age 26 QUEUED 127.0.0.1:6379> exec 1) OK 2) OK 127.0.0.1:6379> get sex "2" 127.0.0.1:6379> get age "26" 127.0.0.1:6379> 127.0.0.1:6379> multi OK 127.0.0.1:6379> set a 100 QUEUED 127.0.0.1:6379> del age QUEUED 127.0.0.1:6379> discard OK 127.0.0.1:6379> get age "26" 127.0.0.1:6379> get a (nil) 127.0.0.1:6379>
二、乐观锁
client-1 开启watch,并在事务中修改name
127.0.0.1:6379> get name "mogui" 127.0.0.1:6379> watch name OK 127.0.0.1:6379> multi OK 127.0.0.1:6379> set name devil QUEUED 127.0.0.1:6379> exec (nil)
client-2 修改name
127.0.0.1:6379> get name "mogui" 127.0.0.1:6379> get name "mogui" 127.0.0.1:6379> set name gong OK 127.0.0.1:6379> get name "gong"
client-1 执行exec
127.0.0.1:6379> exec (nil) 127.0.0.1:6379> get name "gong"
三、发布及订阅消息
client-1 订阅devil频道
127.0.0.1:6379> subscribe devil Reading messages... (press Ctrl-C to quit) 1) "subscribe" 2) "devil" 3) (integer) 1
client-2 发布频道devil消息
127.0.0.1:6379> publish devil hello (integer) 1
client-1 订阅频道接收到的消息
1) "message" 2) "devil" 3) "hello"
