To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

使用redis-cli登錄Redis客戶端

[root@master bin]# ./redis-cli 
127.0.0.1:6379> 

1、查看Redis中所有的key。

127.0.0.1:6379> keys *
1) "person"

2、清除所有的key。

127.0.0.1:6379> flushall
OK
127.0.0.1:6379> keys *
(empty list or set)

3、設置一個key值

127.0.0.1:6379> set str test
OK

4、查看一個key的值

127.0.0.1:6379> get str
"test"
