  • redis安装

    windows环境下安装:

    1:首先下载redis:redis-2.0.2.zip (32 bit),解压。
    从下面地址下:http://code.google.com/p/servicestack/wiki/RedisWindowsDownload,看到下面有redis-2.0.2.zip (32 bit),就是他了,下载完成后,解压到D: edis-2.0.2.
    2:创建redis.conf文件:
    这是一个配置文件,指定了redis的监听端口,timeout等。如下面有:port 6379。
    把下面内容COPY到一新建文件中,取名redis.conf,再保存到redis-2.0.2目录下:


    # Redis configuration file example

    # 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 no

    # When run as a daemon, Redis write a pid file in /var/run/redis.pid by default.
    # You can specify a custom pid file location here.
    pidfile /var/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 connections.
    #
    # bind 127.0.0.1

    # 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)
    # notice (moderately verbose, what you want in production probably)
    # warning (only very important / critical messages are logged)
    loglevel debug

    # Specify the log file name. Also 'stdout' can be used to force
    # the demon 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 stdout

    # 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'-1
    databases 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
    save 900 1
    save 300 10
    save 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 DB
    dbfilename dump.rdb

    # For default save/load DB in/from the working directory
    # Note that you must specify a directory not a file name.
    dir ./

    ################################# 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).
    #
    # 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 limts.
    # 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.log. 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.
    #
    # The name of the append only file is "appendonly.log"
    #
    # IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append
    # log file in background when it gets too big.

    appendonly no

    # 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 "always" that's the safer of the options. It's up to you to
    # understand if you can relax this to "everysec" that will fsync every second
    # or to "no" that will let the operating system flush the output buffer when
    # it want, for better performances (but if you can live with the idea of
    # some data loss consider the default persistence mode that's snapshotting).

    appendfsync always
    # appendfsync everysec
    # appendfsync no

    ############################### 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

    # Use object sharing. Can save a lot of memory if you have many common
    # string in your dataset, but performs lookups against the shared objects
    # pool so it uses more CPU and can be a bit slower. Usually it's a good
    # idea.
    #
    # When object sharing is enabled (shareobjects yes) you can use
    # shareobjectspoolsize to control the size of the pool used in order to try
    # object sharing. A bigger pool size will lead to better sharing capabilities.
    # In general you want this value to be at least the double of the number of
    # very common strings you have in your dataset.
    #
    # WARNING: object sharing is experimental, don't enable this feature
    # in production before of Redis 1.0-stable. Still please try this feature in
    # your development environment so that we can test it better.
    # shareobjects no
    # shareobjectspoolsize 1024

    3:在cmd下面执行以下命令,指定它使用我们的redis.conf,同时也是启动,把redis运行起来,这里指定用redis.conf的配置运行服务
    D: edis-2.0.2>redis-server.exe redis.conf

    4:开一新DOS窗口cmd.执行以下命令,这是Redis的客户端程序:
    redis-cli.exe -h 127.0.0.1 -p 6379
    127.0.0.1是我本机IP地址,端口6379就是上面配置文件中指定的监听端口
    执行完成后,应该能看到redis启动了,这时在第一个cmd窗口可以看到连接信息。
    执行一条保存key value操作
    set mystock 300156
    再查询一下
    get mystock
