linux memcached查看和清理
1.一种telnet localhost 200001 #登陆
stats #查看状态
flush_all #清理
quit #退出
2.又学到一个：
echo 'flush_all' | nc localhost 200001
3.
1、数据存储（假设key为test,value为12345）
printf "set test 0 0 5\r\n12345\r\n" | nc 127.0.0.1 200001
STORED
2、数据取回（假设key为test）
printf "get test\r\n" | nc 127.0.0.1 200001
VALUE test 0 5
12345
END
3、数值增加1（假设key为test,并且value为正整数）
printf "incr test 1\r\n" | nc 127.0.0.1 200001
12346
4、数值减少3（假设key为test,并且value为正整数）
printf "decr test 3\r\n" | nc 127.0.0.1 200001
12343
5、数据删除（假设key为test）
printf "delete test\r\n" | nc 127.0.0.1 11211
DELETED
6、查看Memcached状态
printf "stats\r\n" | nc 127.0.0.1 200001
STAT pid 3025
STAT uptime 4120500
STAT time 1228021767
STAT version 1.2.6
STAT pointer_size 32
STAT rusage_user 433.463103
STAT rusage_system 1224.515845
STAT curr_items 1132460
STAT total_items 8980260
STAT bytes 1895325386
STAT curr_connections 252
STAT total_connections 547850
STAT connection_structures 1189
STAT cmd_get 13619685
STAT cmd_set 8980260
STAT get_hits 6851607
STAT get_misses 6768078
STAT evictions 0
STAT bytes_read 160396238246
STAT bytes_written 260080686529
STAT limit_maxbytes 2147483648
STAT threads 1
END
7、模拟top命令,查看Memcached状态：
printf "stats\r\n" | nc 127.0.0.1 200001
或者
watch "echo stats | nc 127.0.0.1 200001"
