46.3. redis-cli - Command-line client to redis-server

46.3.1. MONITOR

$ redis-cli monitor			
			

46.3.2. save/bgsave/lastsave

save/bgsave 保存持久化将数据,lastsave 查看相关信息

			
redis 127.0.0.1:6379> save
OK
redis 127.0.0.1:6379> bgsave
Background saving started
redis 127.0.0.1:6379> lastsave
(integer) 1373335757
			
			

46.3.3. Pub/Sub 订阅与发布

redis 提供基本的MQ 功能,下面我们做一个演示

开启第一个终端窗口,订阅first second

$ redis-cli
redis 127.0.0.1:6379> SUBSCRIBE first second
Reading messages... (press Ctrl-C to quit)
1) "subscribe"
2) "first"
3) (integer) 1
1) "subscribe"
2) "second"
3) (integer) 2
			

开启第二个终端窗口,分别发送first second

$ redis-cli
redis 127.0.0.1:6379>  PUBLISH second Hello
(integer) 1
redis 127.0.0.1:6379>  PUBLISH first Helloworld!!!
(integer) 1
redis 127.0.0.1:6379> quit
			

现在切换到第一个终端窗口,应该能够看到发送过来的字符串

$ redis-cli
redis 127.0.0.1:6379> SUBSCRIBE first second
Reading messages... (press Ctrl-C to quit)
1) "subscribe"
2) "first"
3) (integer) 1
1) "subscribe"
2) "second"
3) (integer) 2

1) "message"
2) "second"
3) "Hello"

1) "message"
2) "first"
3) "Helloworld!!!"
