  287. 使用vi命令编辑redis.conf文件，将其中的配置参数"daemonize no"修改成"daemonize yes"，表示开启redis服务器的后台启动模式：
  288. [root@hadoop03 bin]# vi redis.conf
  289. # Redis configuration file example
  290.  
  291. # Note on units: when memory size is needed, it is possible to specify
  292. # it in the usual form of 1k 5GB 4M and so forth:
  293. #
  294. # 1k => 1000 bytes
  295. # 1kb => 1024 bytes
  296. # 1m => 1000000 bytes
  297. # 1mb => 1024*1024 bytes
  298. # 1g => 1000000000 bytes
  299. # 1gb => 1024*1024*1024 bytes
  300. #
  301. # units are case insensitive so 1GB 1Gb 1gB are all the same.

  333. 使用redis-server命令后面跟上redis.conf配置文件，就可以以后台模式启动redis服务器：
  334. [root@hadoop03 bin]# ./redis-server redis.conf 
  335.  
  336. 查看redis的进程，说明redis服务器已经成功启动，其默认的端口号为6379：
  337. [root@hadoop03 bin]# ps aux|grep redis
  338. root       4251  0.1  0.3 137448  7544 ?        Ssl  04:58   0:09 bin/redis-server *:6379
  339. root       7275  0.0  0.0 103308   852 pts/1    S+   06:27   0:00 grep redis
  340. [root@hadoop03 bin]# 
  341.  
  342. 启动redis的客户端：
  343. [root@hadoop03 bin]# ./redis-cli 
  344.  
  345. 下面是redis的一些常用命令：
  346. 127.0.0.1:6379> ping
  347. PONG
  348. 127.0.0.1:6379> set a 10
  349. OK
  350. 127.0.0.1:6379> get a
  351. ""
  352. 127.0.0.1:6379> keys *
  353. 1) "a"
  354.  
  355. 让a加1的命令是incr：
  356. 127.0.0.1:6379> incr a
  357. (integer) 11
  358.  
  359. 让a减1的命令是decr：
  360. 127.0.0.1:6379> decr a
  361. (integer) 10
  362. 127.0.0.1:6379> del a
  363. (integer) 1
  364. 127.0.0.1:6379> keys *
  365. (empty list or set)
  366. 127.0.0.1:6379>
  367. [root@hadoop03 bin]# 
  368.  
  369. 然后是redis的常用数据类型是String,Hash,List,Set,SortedSet（其中的List和SortedSet比较耗费性能，因为它们要排序，
  370. 我们比较常用的数据类型是String和Hash，因为它们都是key-value类型的）。

  422. 修改两个地方，一个把端口号"port 6379"改为"port 7001"（为了搭建redis集群，
  423. 我们需要创建6个redis实例，这6个redis实例的端口分别为7001~7006）；
  424. 还要修改一个地方，把配置文件中"# cluster-enabled yes"的注释打开，也就是把前面的"#"去掉，表示开启redis的集群模式：（由于这个redis.conf配置文件的内容非常多，在修改某项配置的时候，如果你不熟悉vi的常用命令，就会很麻烦。这里说一下如何在vi命令下查找指定的配置项，首先使用"vi redis.conf"命令进入配置文件内部，此时先不要进入编辑模式，我们以修改"# cluster-enabled yes"为例来进行说明，首先按"/"键可以进入查找模式，输入"cluster"关键字，然后按回车或者按小写的"n"键，可以向下查找该关键字，按大写的"N"键可以向上查找，等找到之后，按键盘左上角的"ESC"键可以退出查找模式，然后再按"i"键进入到文本编辑模式，这样就可以修改文件内容了。修改完，再按"ESC"键退出编辑模式，最后输入":wq"保存退出即可）

  634. 这里在使用set命令的时候，发现报了一个错误，说集群宕机了。
  635. 但是有人说在使用"./redis-trib.rb"脚本创建集群的时候不能使用hostname，只能使用ip地址。
  636. 而我们上面再创建redis集群的时候使用了hostname，并且还报了如下错误（一开始没仔细看，意味redis集群创建成功了，晕死！）：
  637. "ERR Invalid node address specified: hadoop03:7001"
  638. 所以这里只能把6个redis实例都删除，重新创建。
  639. 然后在使用"./redis-trib.rb"脚本创建redis集群的时候，使用ip地址，而不再使用hostname了。

  649. 然后重新创建6个redis实例，并记得修改各自的redis.conf配置文件，创建的过程这里就不赘述了。
  650. 创建好6个redis实例之后，启动6个redis服务器。然后使用如下命令创建redis机器：
  651.  
  652. 注意，在创建redis集群的时候，一定要先将6个redis实例都启动起来，否则会报如下错误：
  653. "[ERR] Sorry, can't connect to node localhost:7001"
  654. 所以我们先使用自己编写的一个批量启动6个redis实例的脚本"start-all.sh"来启动：
  655. [root@hadoop03 redis-cluster]# ./start-all.sh 
  656.  
  657. 下面开始使用redis-trib.rb脚本来创建redis集群，注意这里我们不要使用hostname，而要使用ip地址，否则创建不成功：

  713. 到这里，看到"[OK] All 16384 slots covered."的日志，说明我们的redis集群终于创建成功了。
  714. 下面我们开始连接redis集群，这里只要使用任意一个redis客户端连接到redis集群中的任意一个redis节点都可以。
  715. 注意这里连接的时候一定要指定"-c"这个参数，它表示集群。
  716. 我们这里就使用redis01下面的redis-cli通过连接7002端口的redis节点进入redis集群：
  717. [root@hadoop03 redis-cluster]# redis01/redis-cli -h 192.168.71.13 -p 7002
