标签：idle turn ras cee i/o director tin hive sage 1、 首先安装先下载redis数据库 目前是2.02版本，也可以到我的115网盘下载： http://115.com/lb/5lbf215 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.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： 用phpinfo 查看到时TS vc9。那么下载的版本就对应好 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 5、phpredis hellow word 开始你的redis使用 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 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 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： 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 windows下redis的安装配置和php扩展使用phpredis 标签：idle turn ras cee i/o director tin hive sage 原文地址：http://www.cnblogs.com/endv/p/7749246.html

2、解压安装文件。得到以下目录
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
ts版 phpredis_5.4_vc9_ts.7z nts版 phpredis_5.4_vc9_nts.7z
extension=php_redis.dll
4、 重启apache ，查看phpinfo 界面。如下则表示安装成功
$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
?>

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）
# 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 6379
port 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 is a number between 0 and ‘databases‘-1
databases 16################################ SNAPSHOTTING ################################### Save the DB on disk:## save ## 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 # 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 # 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
