1、 首先安装先下载redis数据库
   
  下载地址: http://code.google.com/p/servicestack/wiki/RedisWindowsDownload

  目前是2.02版本,也可以到我的115网盘下载: http://115.com/lb/5lbf215



2、解压安装文件。得到以下目录

   

   redis-server.exe:服务程序

   redis-check-dump.exe:本地数据库检查

   redis-check-aof.exe:更新日志检查

   redis-benchmark.exe:性能测试,用以模拟同时由N个客户端发送M个 SETs/GETs 查询 (类似于 Apache 的ab 工具).

   redis.conf    配置文件

   

  3、启动Redis服务(conf文件指定配置文件,若不指定则默认):

    D:\redis-2.0.2>redis-server.exe redis.conf

    

  4、  启动cmd窗口要一直开着,关闭后则Redis服务关闭。

       这时服务开启着,另外开一个窗口进行,设置客户端:

        D:\redis-2.0.2>redis-cli.exe -h 202.117.16.133 -p 6379

        然后可以开始玩了:
     
        

 

  
二、php5.4   连接使用redis  ,

      1、先下载 phpredis.dll扩展包。下载地址:  https://github.com/nicolasff/phpredis/downloads

       

       用phpinfo 查看到时TS vc9。那么下载的版本就对应好  

      ts版 phpredis_5.4_vc9_ts.7z                         nts版  phpredis_5.4_vc9_nts.7z     

     2、解压缩之后得到两个文件,分别将两个文件复制到php 目录的 ext目录下。

     

     3、修改php.ini文件。加入extension 扩展 

         extension=php_igbinary.dll
         extension=php_redis.dll

      4、 重启apache ,查看phpinfo 界面。如下则表示安装成功
   
        

     

  5、phpredis   hellow word    开始你的redis使用

       

<?php     $redis = new Redis();                   //redis对象     $redis->connect("192.168.60.6","6379"); //连接redis服务器     $redis->set("test","Hello World");      //set字符串值     echo $redis->get("test");               //获取值?>

redis 配置文件详细说明,以下摘至 http://www.cnblogs.com/wenanry/archive/2012/02/26/2368398.html

感谢网友分享。

1. Redis默认不是以守护进程的方式运行,可以通过该配置项修改,使用yes启用守护进程

daemonize no

2. 当Redis以守护进程方式运行时,Redis默认会把pid写入/var/run/redis.pid文件,可以通过pidfile指定

pidfile /var/run/redis.pid

3. 指定Redis监听端口,默认端口为6379,作者在自己的一篇博文中解释了为什么选用6379作为默认端口,因为6379在手机按键上MERZ对应的号码,而MERZ取自意大利歌女Alessia Merz的名字

port 6379

4. 绑定的主机地址

bind 127.0.0.1

5.当 客户端闲置多长时间后关闭连接,如果指定为0,表示关闭该功能

timeout 300

6. 指定日志记录级别,Redis总共支持四个级别:debug、verbose、notice、warning,默认为verbose

loglevel verbose

7. 日志记录方式,默认为标准输出,如果配置Redis为守护进程方式运行,而这里又配置为日志记录方式为标准输出,则日志将会发送给/dev/null

logfile stdout

8. 设置数据库的数量,默认数据库为0,可以使用SELECT 命令在连接上指定数据库id

databases 16

9. 指定在多长时间内,有多少次更新操作,就将数据同步到数据文件,可以多个条件配合

save

Redis默认配置文件中提供了三个条件:

save 900 1

save 300 10

save 60 10000

分别表示900秒(15分钟)内有1个更改,300秒(5分钟)内有10个更改以及60秒内有10000个更改。

10. 指定存储至本地数据库时是否压缩数据,默认为yes,Redis采用LZF压缩,如果为了节省CPU时间,可以关闭该选项,但会导致数据库文件变的巨大

rdbcompression yes

11. 指定本地数据库文件名,默认值为dump.rdb

dbfilename dump.rdb

12. 指定本地数据库存放目录

dir ./

13. 设置当本机为slav服务时,设置master服务的IP地址及端口,在Redis启动时,它会自动从master进行数据同步

slaveof

14. 当master服务设置了密码保护时,slav服务连接master的密码

masterauth

15. 设置Redis连接密码,如果配置了连接密码,客户端在连接Redis时需要通过AUTH 命令提供密码,默认关闭

requirepass foobared

16. 设置同一时间最大客户端连接数,默认无限制,Redis可以同时打开的客户端连接数为Redis进程可以打开的最大文件描述符数,如果设置 maxclients 0,表示不作限制。当客户端连接数到达限制时,Redis会关闭新的连接并向客户端返回max number of clients reached错误信息

maxclients 128

17. 指定Redis最大内存限制,Redis在启动时会把数据加载到内存中,达到最大内存后,Redis会先尝试清除已到期或即将到期的Key,当此方法处理 后,仍然到达最大内存设置,将无法再进行写入操作,但仍然可以进行读取操作。Redis新的vm机制,会把Key存放内存,Value会存放在swap区

maxmemory

18. 指定是否在每次更新操作后进行日志记录,Redis在默认情况下是异步的把数据写入磁盘,如果不开启,可能会在断电时导致一段时间内的数据丢失。因为 redis本身同步数据文件是按上面save条件来同步的,所以有的数据会在一段时间内只存在于内存中。默认为no

appendonly no

19. 指定更新日志文件名,默认为appendonly.aof

appendfilename appendonly.aof

20. 指定更新日志条件,共有3个可选值:
no:表示等操作系统进行数据缓存同步到磁盘(快)
always:表示每次更新操作后手动调用fsync()将数据写到磁盘(慢,安全)
everysec:表示每秒同步一次(折衷,默认值)

appendfsync everysec

21. 指定是否启用虚拟内存机制,默认值为no,简单的介绍一下,VM机制将数据分页存放,由Redis将访问量较少的页即冷数据swap到磁盘上,访问多的页面由磁盘自动换出到内存中(在后面的文章我会仔细分析Redis的VM机制)

vm-enabled no

22. 虚拟内存文件路径,默认值为/tmp/redis.swap,不可多个Redis实例共享

vm-swap-file /tmp/redis.swap

23. 将所有大于vm-max-memory的数据存入虚拟内存,无论vm-max-memory设置多小,所有索引数据都是内存存储的(Redis的索引数据 就是keys),也就是说,当vm-max-memory设置为0的时候,其实是所有value都存在于磁盘。默认值为0

vm-max-memory 0

24. Redis swap文件分成了很多的page,一个对象可以保存在多个page上面,但一个page上不能被多个对象共享,vm-page-size是要根据存储的 数据大小来设定的,作者建议如果存储很多小对象,page大小最好设置为32或者64bytes;如果存储很大大对象,则可以使用更大的page,如果不 确定,就使用默认值

vm-page-size 32

25. 设置swap文件中的page数量,由于页表(一种表示页面空闲或使用的bitmap)是在放在内存中的,,在磁盘上每8个pages将消耗1byte的内存。

vm-pages 134217728

26. 设置访问swap文件的线程数,最好不要超过机器的核数,如果设置为0,那么所有对swap文件的操作都是串行的,可能会造成比较长时间的延迟。默认值为4

vm-max-threads 4

27. 设置在向客户端应答时,是否把较小的包合并为一个包发送,默认为开启

glueoutputbuf yes

28. 指定在超过一定的数量或者最大的元素超过某一临界值时,采用一种特殊的哈希算法

hash-max-zipmap-entries 64

hash-max-zipmap-value 512

29. 指定是否激活重置哈希,默认为开启(后面在介绍Redis的哈希算法时具体介绍)

activerehashing yes

30. 指定包含其它的配置文件,可以在同一主机上多个Redis实例之间使用同一份配置文件,而同时各个实例又拥有自己的特定配置文件

include /path/to/local.conf

# Redis configuration file example# Note on units: when memory size is needed, it is possible to specifiy# it in the usual form of 1k 5GB 4M and so forth:## 1k => 1000 bytes# 1kb => 1024 bytes# 1m => 1000000 bytes# 1mb => 1024*1024 bytes# 1g => 1000000000 bytes# 1gb => 1024*1024*1024 bytes## units are case insensitive so 1GB 1Gb 1gB are all the same.# By default Redis does not run as a daemon. Use 'yes' if you need it.# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.daemonize yes# When running daemonized, Redis writes a pid file in /var/run/redis.pid by# default. You can specify a custom pid file location here.pidfile /usr/local/redis/run/redis.pid# Accept connections on the specified port, default is 6379port 6379# If you want you can bind a single interface, if the bind option is not# specified all the interfaces will listen for incoming connections.##bind 192.168.20.12# Close the connection after a client is idle for N seconds (0 to disable)timeout 300# Set server verbosity to 'debug'# it can be one of:# debug (a lot of information, useful for development/testing)# verbose (many rarely useful info, but not a mess like the debug level)# notice (moderately verbose, what you want in production probably)# warning (only very important / critical messages are logged)loglevel verbose# Specify the log file name. Also 'stdout' can be used to force# Redis to log on the standard output. Note that if you use standard# output for logging but daemonize, logs will be sent to /dev/null#logfile stdoutlogfile ./logs/redis.log# Set the number of databases. The default database is DB 0, you can select# a different one on a per-connection basis using SELECT <dbid> where# dbid is a number between 0 and 'databases'-1databases 16################################ SNAPSHOTTING  ################################### Save the DB on disk:##   save <seconds> <changes>##   Will save the DB if both the given number of seconds and the given#   number of write operations against the DB occurred.##   In the example below the behaviour will be to save:#   after 900 sec (15 min) if at least 1 key changed#   after 300 sec (5 min) if at least 10 keys changed#   after 60 sec if at least 10000 keys changed##   Note: you can disable saving at all commenting all the "save" lines.save 900 1save 300 10save 60 10000# Compress string objects using LZF when dump .rdb databases?# For default that's set to 'yes' as it's almost always a win.# If you want to save some CPU in the saving child set it to 'no' but# the dataset will likely be bigger if you have compressible values or keys.rdbcompression yes# The filename where to dump the DBdbfilename dump.rdb# The working directory.## The DB will be written inside this directory, with the filename specified# above using the 'dbfilename' configuration directive.## Also the Append Only File will be created inside this directory.## Note that you must specify a directory here, not a file name.dir ./data/################################# REPLICATION ################################## Master-Slave replication. Use slaveof to make a Redis instance a copy of# another Redis server. Note that the configuration is local to the slave# so for example it is possible to configure the slave to save the DB with a# different interval, or to listen to another port, and so on.## slaveof <masterip> <masterport># If the master is password protected (using the "requirepass" configuration# directive below) it is possible to tell the slave to authenticate before# starting the replication synchronization process, otherwise the master will# refuse the slave request.## masterauth <master-password>################################## SECURITY #################################### Require clients to issue AUTH <PASSWORD> before processing any other# commands.  This might be useful in environments in which you do not trust# others with access to the host running redis-server.## This should stay commented out for backward compatibility and because most# people do not need auth (e.g. they run their own servers).## Warning: since Redis is pretty fast an outside user can try up to# 150k passwords per second against a good box. This means that you should# use a very strong password otherwise it will be very easy to break.## requirepass foobared################################### LIMITS ##################################### Set the max number of connected clients at the same time. By default there# is no limit, and it's up to the number of file descriptors the Redis process# is able to open. The special value '0' means no limits.# Once the limit is reached Redis will close all the new connections sending# an error 'max number of clients reached'.## maxclients 128# Don't use more memory than the specified amount of bytes.# When the memory limit is reached Redis will try to remove keys with an# EXPIRE set. It will try to start freeing keys that are going to expire# in little time and preserve keys with a longer time to live.# Redis will also try to remove objects from free lists if possible.## If all this fails, Redis will start to reply with errors to commands# that will use more memory, like SET, LPUSH, and so on, and will continue# to reply to most read-only commands like GET.## WARNING: maxmemory can be a good idea mainly if you want to use Redis as a# 'state' server or cache, not as a real DB. When Redis is used as a real# database the memory usage will grow over the weeks, it will be obvious if# it is going to use too much memory in the long run, and you'll have the time# to upgrade. With maxmemory after the limit is reached you'll start to get# errors for write operations, and this may even lead to DB inconsistency.## maxmemory <bytes>############################## APPEND ONLY MODE ################################ By default Redis asynchronously dumps the dataset on disk. If you can live# with the idea that the latest records will be lost if something like a crash# happens this is the preferred way to run Redis. If instead you care a lot# about your data and don't want to that a single record can get lost you should# enable the append only mode: when this mode is enabled Redis will append# every write operation received in the file appendonly.aof. This file will# be read on startup in order to rebuild the full dataset in memory.## Note that you can have both the async dumps and the append only file if you# like (you have to comment the "save" statements above to disable the dumps).# Still if append only mode is enabled Redis will load the data from the# log file at startup ignoring the dump.rdb file.## IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append# log file in background when it gets too big.appendonly yes# The name of the append only file (default: "appendonly.aof")appendfilename appendonly.aof# The fsync() call tells the Operating System to actually write data on disk# instead to wait for more data in the output buffer. Some OS will really flush# data on disk, some other OS will just try to do it ASAP.## Redis supports three different modes:## no: don't fsync, just let the OS flush the data when it wants. Faster.# always: fsync after every write to the append only log . Slow, Safest.# everysec: fsync only if one second passed since the last fsync. Compromise.## The default is "everysec" that's usually the right compromise between# speed and data safety. It's up to you to understand if you can relax this to# "no" that will will let the operating system flush the output buffer when# it wants, for better performances (but if you can live with the idea of# some data loss consider the default persistence mode that's snapshotting),# or on the contrary, use "always" that's very slow but a bit safer than# everysec.## If unsure, use "everysec".# appendfsync alwaysappendfsync everysec# appendfsync no################################ VIRTUAL MEMORY ################################ Virtual Memory allows Redis to work with datasets bigger than the actual# amount of RAM needed to hold the whole dataset in memory.# In order to do so very used keys are taken in memory while the other keys# are swapped into a swap file, similarly to what operating systems do# with memory pages.## To enable VM just set 'vm-enabled' to yes, and set the following three# VM parameters accordingly to your needs.vm-enabled no# vm-enabled yes# This is the path of the Redis swap file. As you can guess, swap files# can't be shared by different Redis instances, so make sure to use a swap# file for every redis process you are running. Redis will complain if the# swap file is already in use.## The best kind of storage for the Redis swap file (that's accessed at random)# is a Solid State Disk (SSD).## *** WARNING *** if you are using a shared hosting the default of putting# the swap file under /tmp is not secure. Create a dir with access granted# only to Redis user and configure Redis to create the swap file there.vm-swap-file /tmp/redis.swap# vm-max-memory configures the VM to use at max the specified amount of# RAM. Everything that deos not fit will be swapped on disk *if* possible, that# is, if there is still enough contiguous space in the swap file.## With vm-max-memory 0 the system will swap everything it can. Not a good# default, just specify the max amount of RAM you can in bytes, but it's# better to leave some margin. For instance specify an amount of RAM# that's more or less between 60 and 80% of your free RAM.vm-max-memory 0# Redis swap files is split into pages. An object can be saved using multiple# contiguous pages, but pages can't be shared between different objects.# So if your page is too big, small objects swapped out on disk will waste# a lot of space. If you page is too small, there is less space in the swap# file (assuming you configured the same number of total swap file pages).## If you use a lot of small objects, use a page size of 64 or 32 bytes.# If you use a lot of big objects, use a bigger page size.# If unsure, use the default :)vm-page-size 32# Number of total memory pages in the swap file.# Given that the page table (a bitmap of free/used pages) is taken in memory,# every 8 pages on disk will consume 1 byte of RAM.## The total swap size is vm-page-size * vm-pages## With the default of 32-bytes memory pages and 134217728 pages Redis will# use a 4 GB swap file, that will use 16 MB of RAM for the page table.## It's better to use the smallest acceptable value for your application,# but the default is large in order to work in most conditions.vm-pages 134217728# Max number of VM I/O threads running at the same time.# This threads are used to read/write data from/to swap file, since they# also encode and decode objects from disk to memory or the reverse, a bigger# number of threads can help with big objects even if they can't help with# I/O itself as the physical device may not be able to couple with many# reads/writes operations at the same time.## The special value of 0 turn off threaded I/O and enables the blocking# Virtual Memory implementation.vm-max-threads 4############################### ADVANCED CONFIG ################################ Glue small output buffers together in order to send small replies in a# single TCP packet. Uses a bit more CPU but most of the times it is a win# in terms of number of queries per second. Use 'yes' if unsure.glueoutputbuf yes# Hashes are encoded in a special way (much more memory efficient) when they# have at max a given numer of elements, and the biggest element does not# exceed a given threshold. You can configure this limits with the following# configuration directives.hash-max-zipmap-entries 64hash-max-zipmap-value 512# Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in# order to help rehashing the main Redis hash table (the one mapping top-level# keys to values). The hash table implementation redis uses (see dict.c)# performs a lazy rehashing: the more operation you run into an hash table# that is rhashing, the more rehashing "steps" are performed, so if the# server is idle the rehashing is never complete and some more memory is used# by the hash table.## The default is to use this millisecond 10 times every second in order to# active rehashing the main dictionaries, freeing memory when possible.## If unsure:# use "activerehashing no" if you have hard latency requirements and it is# not a good thing in your environment that Redis can reply form time to time# to queries with 2 milliseconds delay.## use "activerehashing yes" if you don't have such hard requirements but# want to free memory asap when possible.activerehashing yes################################## INCLUDES #################################### Include one or more other config files here.  This is useful if you# have a standard template that goes to all redis server but also need# to customize a few per-server settings.  Include files can include# other files, so use this wisely.## include /path/to/local.conf# include /path/to/other.conf
