  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 5rn12345rn“ | nc 127.0.0.1 200001

  STORED

  2、数据取回(假设key为test)

  printf “get testrn“ | 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 1rn“ | 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 3rn“ | nc 127.0.0.1 200001

  12343

  5、数据删除(假设key为test)

  printf “delete testrn“ | nc 127.0.0.1 11211

  DELETED

  6、查看Memcached状态

  printf “statsrn“ | 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 “statsrn“ | nc 127.0.0.1 200001

  或者

  watch “echo stats | nc 127.0.0.1 200001“
