windows下redis的安裝配置和php擴充使用phpredis

1、 首先安裝先下載redis資料庫

下載地址： http://code.google.com/p/servicestack/wiki/RedisWindowsDownload

目前是2.02版本，也可以到我的115網盤下載： http://115.com/lb/5lbf215

2、解壓安裝檔案。得到以下目錄

redis-server.exe：服務程式

redis-check-dump.exe：本機資料庫檢查

redis-check-aof.exe：更新日誌檢查

redis-benchmark.exe：效能測試，用以類比同時由N個用戶端發送M個 SETs/GETs 查詢 (類似於 Apache 的ab 工具).

redis.conf　　　　設定檔

3、啟動Redis服務（conf檔案指定設定檔，若不指定則預設）：

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

4、 啟動cmd視窗要一直開著，關閉後則Redis服務關閉。

這時服務開啟著，另外開一個視窗進行，設定用戶端：

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

然後可以開始玩了：

　
二、php5.4 串連使用redis ,

1、先下載 phpredis.dll擴充包。下載地址: https://github.com/nicolasff/phpredis/downloads

用phpinfo 查看到時TS vc9。那麼下載的版本就對應好

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

2、解壓縮之後得到兩個檔案，分別將兩個檔案複製到php 目錄的 ext目錄下。

3、修改php.ini檔案。加入extension 擴充

extension=php_igbinary.dll
extension=php_redis.dll

4、 重啟apache ，查看phpinfo 介面。如下則表示安裝成功
　　

　　5、phpredis hellow word　 開始你的redis使用

connect("192.168.60.6","6379"); //串連redis伺服器     $redis->set("test","Hello World");      //set字串值     echo $redis->get("test");               //擷取值?>

感謝網友分享。

1. Redis預設不是以守護進程的方式運行，可以通過該配置項修改，使用yes啟用守護進程

daemonize no

2. 當Redis以守護進程方式運行時，Redis預設會把pid寫入/var/run/redis.pid檔案，可以通過pidfile指定

pidfile /var/run/redis.pid

3. 指定Redis監聽連接埠，預設連接埠為6379，作者在自己的一篇博文中解釋了為什麼選用6379作為預設連接埠，因為6379在手機按鍵上MERZ對應的號碼，而MERZ取自意大利歌女Alessia Merz的名字

port 6379

4. 綁定的主機地址

bind 127.0.0.1

5.當 用戶端閑置多長時間後關閉串連，如果指定為0，表示關閉該功能

timeout 300

6. 指定日誌記錄層級，Redis總共支援四個層級：debug、verbose、notice、warning，預設為verbose

loglevel verbose

7. 日誌記錄方式，預設為標準輸出，如果配置Redis為守護進程方式運行，而這裡又配置為日誌記錄方式為標準輸出，則日誌將會發送給/dev/null

logfile stdout

8. 設定資料庫的數量，預設資料庫為0，可以使用SELECT 命令在串連上指定資料庫id

databases 16

9. 指定在多長時間內，有多少次更新操作，就將資料同步到資料檔案，可以多個條件配合

save

Redis預設設定檔中提供了三個條件：

save 900 1

save 300 10

save 60 10000

分別表示900秒（15分鐘）內有1個更改，300秒（5分鐘）內有10個更改以及60秒內有10000個更改。

10. 指定儲存至本機資料庫時是否壓縮資料，預設為yes，Redis採用LZF壓縮，如果為了節省CPU時間，可以關閉該選項，但會導致資料庫檔案變的巨大

rdbcompression yes

11. 指定本機資料庫檔案名稱，預設值為dump.rdb

dbfilename dump.rdb

12. 指定本機資料庫存放目錄

dir ./

13. 設定當本機為slav服務時，設定master服務的IP地址及連接埠，在Redis啟動時，它會自動從master進行資料同步

slaveof

14. 當master服務設定了密碼保護時，slav服務串連master的密碼

masterauth

15. 設定Redis串連密碼，如果配置了串連密碼，用戶端在串連Redis時需要通過AUTH 命令提供密碼，預設關閉

requirepass foobared

16. 設定同一時間最大用戶端串連數，預設無限制，Redis可以同時開啟的用戶端串連數為Redis進程可以開啟的最大檔案描述符數，如果設定 maxclients 0，表示不作限制。當用戶端串連數到達限制時，Redis會關閉新的串連並向用戶端返回max number of clients reached錯誤資訊

maxclients 128

17. 指定Redis最大記憶體限制，Redis在啟動時會把資料載入到記憶體中，達到最大記憶體後，Redis會先嘗試清除已到期或即將到期的Key，當此方法處理 後，仍然到達最大記憶體設定，將無法再進行寫入操作，但仍然可以進行讀取操作。Redis新的vm機制，會把Key存放記憶體，Value會存放在swap區

maxmemory

18. 指定是否在每次更新操作後進行日誌記錄，Redis在預設情況下是非同步把資料寫入磁碟，如果不開啟，可能會在斷電時導致一段時間內的資料丟失。因為 redis本身同步資料檔案是按上面save條件來同步的，所以有的資料會在一段時間內只存在於記憶體中。預設為no

appendonly no

19. 指定更新記錄檔名，預設為appendonly.aof

appendfilename appendonly.aof

20. 指定更新日誌條件，共有3個可選值：
no：表示等作業系統進行資料緩衝同步到磁碟（快）
always：表示每次更新操作後手動調用fsync()將資料寫到磁碟（慢，安全）
everysec：表示每秒同步一次（折衷，預設值）

appendfsync everysec

21. 指定是否啟用虛擬記憶體機制，預設值為no，簡單的介紹一下，VM機制將資料分頁存放，由Redis將訪問量較少的頁即冷資料swap到磁碟上，訪問多的頁面由磁碟自動換出到記憶體中（在後面的文章我會仔細分析Redis的VM機制）

vm-enabled no

22. 虛擬記憶體檔案路徑，預設值為/tmp/redis.swap，不可多個Redis執行個體共用

vm-swap-file /tmp/redis.swap

23. 將所有大於vm-max-memory的資料存入虛擬記憶體,無論vm-max-memory設定多小,所有索引資料都是記憶體儲存的(Redis的索引資料 就是keys),也就是說,當vm-max-memory設定為0的時候,其實是所有value都存在於磁碟。預設值為0

vm-max-memory 0

24. Redis swap檔案分成了很多的page，一個對象可以儲存在多個page上面，但一個page上不能被多個對象共用，vm-page-size是要根據儲存的 資料大小來設定的，作者建議如果儲存很多小對象，page大小最好設定為32或者64bytes；如果儲存很大大對象，則可以使用更大的page，如果不 確定，就使用預設值

vm-page-size 32

25. 設定swap檔案中的page數量，由於頁表（一種表示頁面空閑或使用的bitmap）是在放在記憶體中的，，在磁碟上每8個pages將消耗1byte的記憶體。

vm-pages 134217728

26. 設定訪問swap檔案的線程數,最好不要超過機器的核心數,如果設定為0,那麼所有對swap檔案的操作都是串列的，可能會造成比較長時間的延遲。預設值為4

vm-max-threads 4

27. 設定在向用戶端應答時，是否把較小的包合并為一個包發送，預設為開啟

glueoutputbuf yes

28. 指定在超過一定的數量或者最大的元素超過某一臨界值時，採用一種特殊的雜湊演算法

hash-max-zipmap-entries 64

hash-max-zipmap-value 512

29. 指定是否啟用重設雜湊，預設為開啟（後面在介紹Redis的雜湊演算法時具體介紹）

activerehashing yes

30. 指定包含其它的設定檔，可以在同一主機上多個Redis執行個體之間使用同一份設定檔，而同時各個執行個體又擁有自己的特定設定檔

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.

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  # 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 ################################## SECURITY #################################### Require clients to issue AUTH  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 ############################## 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

後期更新redis 一些詳細操作。謝謝。
