586. 第三步：启动进程
     
587. #redis-server /etc/redis.conf
     
588. 查看进程有没有成功启动
     
589. #ps -ef | grep redis
       p" z" X; n2 q& E
590. 测试输入一个键值
     " r$ z; p& y2 F
591. #redis-cli set test "testredis"
     / }  {+ H2 z+ u
592. 获取键值
     
593. #redis-cli get test
     / v& _, z) u  z2 E8 o0 R- F
594. 
     
595. 
     
596. 第四步:关闭redis  (这个是更改配置文件后 正常的重启方式  不重新加载redis配置跳过)
     
597. # redis-cli shutdown      //关闭所有   
     
598. 关闭某个端口上的redis   
     4 s, I+ K3 Q! ?6 |  X+ B
599. # redis-cli -p 6397 shutdown  //关闭6397端口的redis  
     5 ]7 C8 d7 a5 A2 T
600. 说明：关闭以后缓存数据会自动dump到硬盘上，硬盘地址见redis.conf中的dbfilename  dump.rdb

602. 
     
603. 第5步:php扩展安装
     / m  K$ k- k5 `
604. phpredis PHP扩展下载地址
     
605. https://github.com/nicolasff/phpredis/tree/2.2.2
     " x6 t1 L9 k! x3 {" i6 R) Y- k
606. 选择最新版本下载zip
     
607. 
     & @" e  v  h4 `* e; H+ R
608. 然后自己上传zip  用unzip解压到当前目录 unzip 文件名
     
609. 
     4 a# K  @0 y& Y6 T+ f8 {
610. # cd owlient-phpredis-90ecd17/   #打开解压后的文件夹里面  这个解压后的目录 要是不知道 可以输入 "dir" 查看
     : `% h6 B! e1 u3 R; j$ q* Y5 e5 R2 x
611. # /www/nginx_php-5.2.17/bin
     
612. # ./configure --with-php-config=/www/nginx_php-5.2.17/bin/php-config
     
613. #make
     
614. #make install   #记录产生的redis.so路径
     / r, P! Z' p; q+ r
615. 
     
616. 修改php.ini文件
     
617. 在php.ini中添加如下一行：
     7 \; @- S6 R7 O: i: S+ _. O
618. extension=/?/redis.so  #是刚刚记录的产生redis.so的路 写在 ?那
     
619. 重启 使之生效：
     ; E7 e) \+ r, F9 L( e6 @2 p; s
620. /usr/local/php/sbin/php-fpm reload
     
621. /usr/local/nginx/sbin/nginx -s reload
     1 m5 v+ {* w3 @; }0 I: }: @. N
622. 
     6 H" M7 D' s! n+ t5 d+ O1 C7 A
623. 将 Redis 作为 Linux 服务随机启动
     
624. vi /etc/rc.local, 加入代码：
     6 J" ^$ d% C2 I8 e: a4 J' C7 f5 x, K( q
625. /root/redis-2.6.10/src/redis-serve  #路径看情况修改
     2 f7 o7 f/ _8 z- B7 m# N- X3 `
626. 
     
627. redis-cli -h localhost -p 6379 info  #命令要在redis目录下面执行
     
628. 提供host为localhost，端口为6379，redis服务的统计信息
     
629. 
     
630. 
     $ l, y( z) F5 R  X5 q' m0 P
631. 就这样你的web服务器就支持redis了 记得要在 给dz 的配置文件 加上12.0.0.1哦
     3 B9 T/ N2 m- U. y7 I
632. dz配置文件在 config目录下面的 config_global.php
     - G* x3 |* l  y6 l7 _% W
633. $_config['memory']['redis']['server'] = '127.0.0.1';
     
634. $_config['memory']['redis']['port'] = 6379;
     
635. $_config['memory']['redis']['pconnect'] = 1;
     ; M7 Q# m# @% c( L; Y2 q" o
636. $_config['memory']['redis']['timeout'] = '0';
     
637. $_config['memory']['redis']['serializer'] = 1;
