安裝redis，使用一種你熟悉的高階語言（例如ruby，python等）在redis裡建立資料併成功訪問作為測試

    [

[email protected] redis-2.8.4]# make

    zmalloc.o: In function `zmalloc_used_memory':
    /var/lib/tcommsvr/redis-2.8.0-rc4/src/zmalloc.c:223: undefined reference to `__sync_add_and_fetch_4'
    collect2: ld returned 1 exit status
    make[1]: *** [redis-server] Error 1
    make[1]: Leaving directory `/var/lib/tcommsvr/redis-2.8.0-rc4/src'
    make: *** [all] Error 2

    產生原因：

    linux為32位版本。
    檢視方式：getconf LONG_BIT


    解決辦法：

    執行make命令時加引數：make CFLAGS="-march=i686"

    make CFLAGS="-march=i686"

2.啟動：

    [[email protected] src]# ./redis-server --port 9999
    [15894] 15 Jan 16:20:23.114 * Max number of open files set to 10032
    [15894] 15 Jan 16:20:23.117 # Warning: 32 bit instance detected but no memory limit set. Setting 3 GB maxmemory limit with 'noeviction' policy now.
    ...

3.測試連線

    [[email protected] redis-2.8.4]# telnet localhost  9999
    Trying 127.0.0.1...
    Connected to localhost.localdomain (127.0.0.1).
    Escape character is '^]'.
    get a^H
    $-1
    set a
    -ERR wrong number of arguments for 'set' command
    set hpp 4
    +OK
    set hoge 4
    +OK
    abcd
    -ERR unknown command 'abcd'
    set hoge 4
    +OK
    get hoge
    $1
    4
    setex foo 5 3
    +OK
    get foo
    $-1
    get foo
    $-1
    setex foo 5 10
    +OK

4.安裝Python    

4.1．下載原始碼
        http://www.python.org/ftp/python/2.5.2/Python-2.5.2.tar.bz2

4.2．  安裝 Python

       $ tar –jxvf Python-2.7.6.tgz
       $ cd Python-2.7.6
        ./configure
        make
        make install

4.3 測試開啟python

    [[email protected] redis-2.7.2]# python
    Python 2.7.6 (default, Jan 16 2014, 17:54:06)
    [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import redis
    >>> r= redis.StrictRedis(host='localhost',port=6379,db=0)
    >>> r.set('foo','bar')




4.4 啟動redis

    [[email protected] /]# cd /download/redis-2.8.4/
    [[email protected] redis-2.8.4]# vi redis.conf
    [[email protected] redis-2.8.4]# src/redis-server redis.conf
    [28781] 17 Jan 09:50:40.200 * Max number of open files set to 10032
    [28781] 17 Jan 09:50:40.203 # Warning: 32 bit instance detected but no memory limit set. Setting 3 GB maxmemory limit with 'noeviction' policy now.

    [28781] 17 Jan 09:50:40.205 # Server started, Redis version 2.8.4
    [28781] 17 Jan 09:50:40.205 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
    [28781] 17 Jan 09:50:40.206 * The server is now ready to accept connections on port 6379



4.5 使用python 連線redis


    [[email protected] opt]# python
    Python 2.7.6 (default, Jan 16 2014, 17:54:06)
    [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import redis
    >>> redisClient=redis.StrictRedis(host='127.0.0.1',port=6379,db=0)
    >>> redisClient.set('test_redis','Hello Python')
    True
    >>> value=redisClient.get('test_redis')
    >>> print value
    Hello Python
    >>> redisClient.delete('test_redis')
    True
    >>> value=redisClient.get('test_redis')
    >>> print value
    None
    >>>

4.6 4.測試例項：
    4.6 4.1.把文字資料匯入到redis
    [[email protected] backup]# cat test_data.txt
    wolys # wolysopen111 # [email protected]
    coralshanshan # 601601601 # [email protected]

    leochenlei # leichenlei # [email protected]
    z370433835 # lkp145566 # [email protected]


    4.6 4.2.建立命令指令碼

    [[email protected] backup]# vi imp_redis.py
    [[email protected] backup]# cat imp_redis.py
    import redis
    import re
    pool = redis.ConnectionPool(host='127.0.0.1', port=6379)
    r = redis.Redis(connection_pool=pool)
    pipe = r.pipeline()
    p=re.compile(r'(.*)\s#\s(.*)\s#\s(.*)');
    pipe = r.pipeline()
    f = open("/opt/backup/test_data.txt")
    matchs=p.findall(f.read())
    for user in matchs:
       key='users_%s' %user[0].strip()
       pipe.hset(key,'pwd',user[1].strip()).hset(key,'email',user[2].strip())
    pipe.execute()
    f.close()

    4.6 4.3.執行指令碼

    [[email protected] backup]# python imp_redis.py

4.6 4.4.檢視匯入資料

    -bash: redis-cli: command not found
    [[email protected] src]# ./redis-cli
    127.0.0.1:6379> keys *
     1) "users_simulategirl"
