redis的数据类型:

[ ~/redis-2.0.0]$ ./redis-cli -h

usage: redis-cli [-h host] [-p port] [-a authpw] [-r repeat_times] [-n db_num] [-i] cmd arg1 arg2
arg3 ... argN

usage: echo "argN" | redis-cli -c [-h host] [-p port] [-a authpw] [-r repeat_times] [-n db_num] cmd

Redis根据5种不同的数据类型来操作数据对象:

操作String类型的值:

Command Parameters Description

SETNX key value Set a key to a string value if the key does not exist

SETEX key time value Set+Expire combo command

MSET key1 value1 key2 value2 ... keyN valueN Set multiple keys to multiple
values in a single atomic operation

MSETNX key1 value1 key2 value2 ... keyN valueN Set multiple keys to multiple
values in a single atomic operation if none of the keys already exist

INCR key Increment the integer value of key

INCRBY key integer Increment the integer value of key by integer

DECR key Decrement the integer value of key

Redis的master/slave复制:

Redis的master/slave数据复制方式可以是一主一从或者是一主多从的方式,Redis在
master是非阻塞模式,也就是说在slave执行数据同步的时候,master是可以接受客户端的
请求的,并不影响同步数据的一致性,然而在slave端是阻塞模式的,slave在同步master
数据时,并不能够响应客户端的查询

Redis的master/slave模式下,master提供数据读写服务,而slave只提供读服务

Redis的master/slave的配置方式是在slave主机的Redis目录下的redis.conf配置文件中
添加:

slaveof master_ip master_port

例如:

我们配置我们的slave为:redis-slave.conf

daemonize yes

pidfile redis-slave.pid

port 6380

timeout 300

loglevel verbose

logfile stdout

databases 16

save 900 1

save 300 10

save 60 10000

rdbcompression yes

dbfilename dump-slave.rdb

dir /home/falcon/redis-2.0.0/

slaveof 127.0.0.1 6379

appendonly no

Redis可以做一主一从,也可以做一主多从,更可以做一主一从,在从下面挂从,大家
可以根据需求做这样的试验
