2 解压到你所需要的目录中

 

3 创建redis.conf文件

 

    # 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  

 

 4 在命令行下启动服务

   

启动成功后显示（此窗口会一直滚动，不要关闭，否则redis就停止了）

 

5 设置redis服务客户端

 

之后会显示

 

6 测试

 

window下安装成功

 

二、PHP中使用

1 添加phpredis扩展

 首先，查看所用php编译版本V6/V9 在phpinfo()中查看

 

 

2 下载扩展 地址：https://github.com/nicolasff/phpredis/downloads（注意所支持的php版本）

 

3 将下载的php_redis.dll放在php扩展目录中（ext），并修改配置文件php.ini（添加extension=php_redis.dll）

 

4 重新启动服务，查看phpinfo(),下面表示成功；

 

 

5 用PHP测试

$redis = new Redis();  
$redis->connect("192.168.138.2","6379");  //php客户端设置的ip及端口  
//存储一个 值  
$redis->set("say","Hello World");  
echo $redis->get("say");     //应输出Hello World  
  
//存储多个值  
$array = array('first_key'=>'first_val',  
          'second_key'=>'second_val',  
          'third_key'=>'third_val');  
$array_get = array('first_key','second_key','third_key');  
$redis->mset($array);  
var_dump($redis->mget($array_get));
