LINUX命令行 查看memcache运行状态

1、确保memcache是启动的

2、 /etc/rc.d/init.d/memcached start &

3、链接进入telnet localhost 11211
4、stats 命令

这些状态的说明如下：pidmemcache服务器的进程IDuptime服务器已经运行的秒数time服务器当前的unix时间戳versionmemcache版本pointer_size当前操作系统的指针大小（32位系统一般是32bit）rusage_user进程的累计用户时间rusage_system进程的累计系统时间curr_items服务器当前存储的items数量total_items从服务器启动以后存储的items总数量bytes当前服务器存储items占用的字节数curr_connections当前打开着的连接数total_connections从服务器启动以后曾经打开过的连接数connection_structures服务器分配的连接构造数cmd_getget命令（获取）总请求次数cmd_setset命令（保存）总请求次数get_hits总命中次数get_misses总未命中次数evictions为获取空闲内存而删除的items数（分配给memcache的空间用满后需要删除旧的items来得到空间分配给新的items）bytes_read总读取字节数（请求字节数）bytes_written总发送字节数（结果字节数）limit_maxbytes分配给memcache的内存大小（字节）threads当前线程数


5、memcached -u root -vvv  系统初始化trunk列表
