$ wget http://download.redis.io/releases/redis-2.8.17.tar.gz
$ tar xzf redis-2.8.17.tar.gz
$ cd redis-2.8.17
$ make

Run Redis with:

$ src/redis-server

You can interact with Redis using the built-in client:

$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"

Redis 由四个可执行文件:

redis-server: Redis服务器的daemon启动程序
redis-cli: Redis命令行操作工具。当然，你也可以用telnet根据其纯文本协议来操作
redis-benchmark: Redis性能测试工具，测试Redis在你的系统及你的配置下的读写性能
redis-stat: Redis状态检测工具，可以检测Redis当前状态参数及延迟状况

redis只有一个启动参数，就是他的配置文件路径
redis-server /etc/redis.conf

ps:默认复制过去的redis.conf文件的daemonize参数为no，所以redis不会在后台运行，这时要测试，我们需要重新开一个终端。修改为yes则为后台运行redis。另外配置文件中规定了pid文件，log文件和数据文件的地址，如果有需要先修改，默认log信息定向到stdout.

daemonize：是否以后台daemon方式运行
pidfile：pid文件位置
port：监听的端口号
timeout：请求超时时间
loglevel：log信息级别
logfile：log文件位置
databases：开启数据库的数量
save * *：保存快照的频率，第一个*表示多长时间，第三个*表示执行多少次写操作。在一定时间内执行一定数量的写操作时，自动保存快照。可设置多个条件。
rdbcompression：是否使用压缩
dbfilename：数据快照文件名（只是文件名，不包括目录）
dir：数据快照的保存目录（这个是目录）
appendonly：是否开启appendonlylog，开启的话每次写操作会记一条log，这会提高数据抗风险能力，但影响效率。
appendfsync：appendonlylog如何同步到磁盘（三个选项，分别是每次写都强制调用fsync、每秒启用一次fsync、不调用fsync等待系统自己同步）

更改redis.conf daemonize no 为 yes 默认后台启动这样就不用新启一个终端了运行时加上更改后的配置文件名redis.conf

#启动:
[root@iZ2591ffv58Z redis-2.8.17]# src/redis-cli 
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit

[root@iZ2591ffv58Z redis-2.8.17]# src/redis-server redis.conf
#按照redis.conf这个配置文件启动

[root@iZ2591ffv58Z redis-2.8.17]# src/redis-cli
127.0.0.1:6379> 

#关闭redis
[root@iZ2591ffv58Z redis-2.8.17]# src/redis-cli -h 127.0.0.1 -p 6379 shutdown

#ps:查看端口
netstat -tulnp | grep redis

ps:redis-cli --help

[root@iZ2591ffv58Z redis-2.8.17]# src/redis-cli -h
redis-cli 2.8.17

Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]
  -h <hostname>      Server hostname (default: 127.0.0.1).
  -p <port>          Server port (default: 6379).
  -s <socket>        Server socket (overrides hostname and port).
  -a <password>      Password to use when connecting to the server.
  -r <repeat>        Execute specified command N times.
  -i <interval>      When -r is used, waits <interval> seconds per command.
                     It is possible to specify sub-second times like -i 0.1.
  -n <db>            Database number.
  -x                 Read last argument from STDIN.
  -d <delimiter>     Multi-bulk delimiter in for raw formatting (default: \n).
  -c                 Enable cluster mode (follow -ASK and -MOVED redirections).
  --raw              Use raw formatting for replies (default when STDOUT is
                     not a tty).
  --no-raw           Force formatted output even when STDOUT is not a tty.
  --csv              Output in CSV format.
  --latency          Enter a special mode continuously sampling latency.
  --latency-history  Like --latency but tracking latency changes over time.
                     Default time interval is 15 sec. Change it using -i.
  --slave            Simulate a slave showing commands received from the master.
  --rdb <filename>   Transfer an RDB dump from remote server to local file.
  --pipe             Transfer raw Redis protocol from stdin to server.
  --pipe-timeout <n> In --pipe mode, abort with error if after sending all data.
                     no reply is received within <n> seconds.
                     Default timeout: 30. Use 0 to wait forever.
  --bigkeys          Sample Redis keys looking for big keys.
  --scan             List all keys using the SCAN command.
  --pattern <pat>    Useful with --scan to specify a SCAN pattern.
  --intrinsic-latency <sec> Run a test to measure intrinsic system latency.
                     The test will run for the specified amount of seconds.
  --eval <file>      Send an EVAL command using the Lua script at <file>.
  --help             Output this help and exit.
  --version          Output version and exit.

Examples:
  cat /etc/passwd | redis-cli -x set mypasswd
  redis-cli get mypasswd
  redis-cli -r 100 lpush mylist x
  redis-cli -r 100 -i 1 info | grep used_memory_human:
  redis-cli --eval myscript.lua key1 key2 , arg1 arg2 arg3
  redis-cli --scan --pattern '*:12345*'

  (Note: when using --eval the comma separates KEYS[] from ARGV[] items)

When no command is given, redis-cli starts in interactive mode.
Type "help" in interactive mode for information on available commands.

[root@iZ2591ffv58Z redis-2.8.17]# src/redis-cli
127.0.0.1:6379> help
redis-cli 2.8.17
Type: "help @<group>" to get a list of commands in <group>
      "help <command>" for help on <command>
      "help <tab>" to get a list of possible help topics
      "quit" to exit

Complete!
