下載最新穩定版本redis源碼包：
liang@bogon:~/redis3$ wget http://download.redis.io/releases/redis-3.0.5.tar.gz
liang@bogon:~/redis3$ ls
編譯安裝redis：
下載成功，解壓redis源碼包
liang@bogon:~/redis3$ tar zxvf redis-3.0.5.tar.gz
liang@bogon:~/redis3/redis-3.0.5$ ls 解壓縮後，進入redis源碼目錄
liang@bogon:~/redis3$ cd redis-3.0.5/
liang@bogon:~/redis3/redis-3.0.5$ ls
liang@bogon:~/redis3/redis-3.0.5$ make
liang@bogon:~/redis3/redis-3.0.5$ sudo make install liang@bogon:~/redis3/redis-3.0.5$ make test 出錯提示：
You need tcl 8.5 or newer in order to run the Redis test
Makefile:211: recipe for target 'test' failed
make[1]: *** [test] Error 1
make[1]: Leaving directory '/home/liang/redis3/redis-3.0.5/src'
Makefile:6: recipe for target 'test' failed
make: *** [test] Error 2安裝tcl 8.5支持redis
liang@bogon:~/redis3/redis-3.0.5$ sudo apt-get install tcl再次測試redis安裝是否成功
liang@bogon:~/redis3/redis-3.0.5$ make test 不再提示需要依賴，redis可以正常運行了
redis的配置文件在redis-3.0.5目錄下的redis.conf，不指定配置文件redis使用默認配置
在配置文件可以設置port、pidfile、daemonize、bind等等配置項
測試redis功能：
啓動redis服務器 liang@bogon:~/redis3/redis-3.0.5$ src/redis-server啓動redis命令行
liang@bogon:~/redis3/redis-3.0.5$ redis-cli設置一個鍵值
127.0.0.1:6379> set joy yes查詢鍵值joy的值是否爲yes
127.0.0.1:6379> get joy2、C客戶端連接redis
下載redis客戶端C語言源碼包：
安裝github下載工具
liang@bogon:~$ sudo apt-get install git從github下載C客戶端源碼包
liang@bogon:~$ git clone https://www.github.com/redis/hiredis編譯安裝redis客戶端：
下載後進入，hredis目錄
liang@bogon:~$ cd hiredis/
liang@bogon:~/hiredis$ make
liang@bogon:~/hiredis$ sudo make install
拷貝庫文件到系統默認的庫目錄
liang@bogon:~/hiredis$ sudo cp libhiredis.so /usr/lib重新加載庫
sudo idconfig進入examples目錄
liang@bogon:~/hiredis$ cd examples/編譯生成一個客戶端
liang@bogon:~/hiredis/examples$ gcc example.c -o example -lhiredis若提示一些如read.h等頭文件error，進入hiredis，執行下面命令，重新編譯
liang@bogon:~/hiredis$ sudo cp *.h /usr/include/測試redis客戶端功能：
運行example
liang@bogon:~/hiredis/examples$ ./example
出現下面結果，即C客戶端操作redis成功
PING: PONG
SET: OK
SET (binary API): OK
GET foo: hello world
INCR counter: 1
INCR counter: 2
0) element-9
1) element-8
2) element-7
3) element-6
4) element-5
5) element-4
6) element-3
7) element-2
8) element-1
9) element-0然後就可以開始真正的用C編寫操作redis數據庫了,最後附上example.c源碼，在hiredis目錄也有

#include <stdlib.h>
#include <string.h>
#include <hiredis.h>
