1.网址:http://code.google.com/p/memcache-top/ 下载程序,放到linux下
2.如果执行perl memcache-top-v0.6 --instances=127.0.0.1:11212,127.0.0.1:11211 出现如下错误:
Can't locate Time/HiRes.pm in @INC

Can't locate CPAN.pm in @INC (解决办法:http://bbs.chinaunix.net/thread-1290287-1-1.html) OK
需要安装的软件:Time-HiRes-1.9725 Test-Harness-3.26 Test-Simple-0.98 CPAN-1.9402
安装方法:解压后,进入目录执行如下命令:
perl Makefile.PL

make install
http://search.cpan.org/ 查找下载所需软件
perl /root/soft/memcache-top-v0.6 --instances=218.245.5.77 --port 20130
执行后,显示:
