问题描述

请问：用java代码调用memcached的启动，为何memcached没有反应？谢谢！

解决方案

你的命令不正确，使用

String cmdStr = "F:/memcached_en32or64/x64/memcached.exe –d start";

具体命令如下：

C:memcached>memcached.exe -h
memcached 1.2.6
-p TCP port number to listen on (default: 11211)
-U UDP port number to listen on (default: 0, off)
-s unix socket path to listen on (disables network support)
-a access mask for unix socket, in octal (default 0700)
-l interface to listen on, default is INDRR_ANY
-d start tell memcached to start
-d restart tell running memcached to do a graceful restart
-d stop|shutdown tell running memcached to shutdown
-d install install memcached service
-d uninstall uninstall memcached service
-r maximize core file limit
-u assume identity of (only when run as root)
-m max memory to use for items in megabytes, default is 64 MB
-M return error on memory exhausted (rather than removing items)
-c max simultaneous connections, default is 1024
-k lock down all paged memory. Note that there is a
limit on how much memory you may lock. Trying to
allocate more than that would fail, so be sure you
set the limit correctly for the user you started
the daemon with (not for -u user;
under sh this is done with 'ulimit -S -l NUM_KB').
-v verbose (print errors/warnings while in event loop)
-vv very verbose (also print client commands/reponses)
-h print this help and exit
-i print memcached and libevent license
-b run a managed instanced (mnemonic: buckets)
-P save PID in , only used with -d option
-f chunk size growth factor, default 1.25
-n minimum space allocated for key+value+flags, default 48

解决方案二：

先命令行执行，看能否启动，证明mc安装好了。
其次就是看你的就Java中执行返回的结果是否有错误码，然后再分析对应原因。

解决方案三：

没有关于memcached账户的配置文件加载啊
