Complete! （二）启动redis:

[plain] 
[root@localhost etc]# redis-server /etc/redis.conf 
[root@localhost etc]# ps -ef | grep redis 
root     17699     1  0 12:05 ?        00:00:00 redis-server /etc/redis.conf 
root     17762 17615  0 12:49 pts/1    00:00:00 grep redis 

[root@localhost etc]# redis-server /etc/redis.conf
[root@localhost etc]# ps -ef | grep redis
root     17699     1  0 12:05 ?        00:00:00 redis-server /etc/redis.conf
root     17762 17615  0 12:49 pts/1    00:00:00 grep redis （三）用telnet连接并测试：

[plain] 
[root@localhost etc]# telnet localhost 6379 
Trying 127.0.0.1... 
Connected to localhost.localdomain (127.0.0.1). 
Escape character is '^]'. 
set key1 4 
+OK 
get key1 
$1 
4 
set key2 hello 
+OK 
get key2 
$5 
hello 
quit 
+OK 
Connection closed by foreign host. 

[root@localhost etc]# telnet localhost 6379

set key1 4
+OK
get key1

set key2 hello
+OK
get key2
$5

>>> import redis 
>>> r = redis.Redis(host='127.0.0.1', port=6379, db=0) 
>>> r.set('name', 'zhangshan') 
True 
>>> r.get('name') 
'zhangshan' 
>>> r.set('age', 22) 
True 
>>> r.get('age') 
'22' 
>>> r.dbsize() 
5L 
>>> r.flushdb() 
True 
>>> r.get('name') 
>>> r.dbsize() 
0L
