使用命令行链接并查看memcached数据

首先链接memcached

telnet 127.0.0.0 11211

而后列出全部items

stats items

结果以下

STAT items:5:number 3

STAT items:5:number_hot 0

STAT items:5:number_warm 0

STAT items:5:number_cold 3

STAT items:5:age_hot 0

STAT items:5:age_warm 0

STAT items:5:age 81407

STAT items:5:mem_requested 720

STAT items:5:evicted 0

STAT items:5:evicted_nonzero 0

STAT items:5:evicted_time 0

STAT items:5:outofmemory 0

STAT items:5:tailrepairs 0

STAT items:5:reclaimed 5

STAT items:5:expired_unfetched 4

STAT items:5:evicted_unfetched 0

STAT items:5:evicted_active 0

STAT items:5:crawler_reclaimed 1

STAT items:5:crawler_items_checked 170

STAT items:5:lrutail_reflocked 16

STAT items:5:moves_to_cold 29

STAT items:5:moves_to_warm 20

STAT items:5:moves_within_lru 25

STAT items:5:direct_reclaims 0

STAT items:5:hits_to_hot 0

STAT items:5:hits_to_warm 25

STAT items:5:hits_to_cold 24

STAT items:5:hits_to_temp 0

STAT items:15:number 1

STAT items:15:number_hot 0

STAT items:15:number_warm 0

STAT items:15:number_cold 1

STAT items:15:age_hot 0

STAT items:15:age_warm 0

STAT items:15:age 30

STAT items:15:mem_requested 1950

STAT items:15:evicted 0

STAT items:15:evicted_nonzero 0

STAT items:15:evicted_time 0

STAT items:15:outofmemory 0

STAT items:15:tailrepairs 0

STAT items:15:reclaimed 10

STAT items:15:expired_unfetched 0

STAT items:15:evicted_unfetched 0

STAT items:15:evicted_active 0

STAT items:15:crawler_reclaimed 0

STAT items:15:crawler_items_checked 6

STAT items:15:lrutail_reflocked 128

STAT items:15:moves_to_cold 185

STAT items:15:moves_to_warm 174

STAT items:15:moves_within_lru 0

STAT items:15:direct_reclaims 0

STAT items:15:hits_to_hot 1

STAT items:15:hits_to_warm 0

STAT items:15:hits_to_cold 184

STAT items:15:hits_to_temp 0

而后经过itemid获取item下的全部key

例如获取itemid为5的全部key(5是id，0是获取全部)

stat cachedump 5 0

结果：

ITEM 02a576f1b8416724f119693470f713b9 [145 b; 1571811395 s] ITEM 0180882b03dc215c916481cfd46ffe71 [145 b; 1571801564 s] ITEM 6c2f83523dc06bb029bb2981940d5a40 [145 b; 1571730004 s]

最后经过get命令获取指定key的数据

get 02a576f1b8416724f119693470f713b9

经过该命令就能够获取到指定key的数据了
