Memcached服务安装

简介：
Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提高动态、数据库驱动网站的速度。Memcached基于一个存储键/值对的hashmap。其守护进程（daemon ）是用C写的，但是客户端可以用任何语言来编写，并通过memcached协议与守护进程通信。
特点：
memcached作为高速运行的分布式缓存服务器，具有以下的特点。
· 协议简单
· 基于libevent的事件处理
· 内置内存存储方式
· memcached不互相通信的分布式

具体实验：
实验环境：两台CentOS7.3系统完成（一台Memcached服务器，一台基于LAMP架构进行的Memcached API客户端）

Memcached服务器     IP：192.168.120.128
Memcached API客户端  IP：192.168.120.135

Nagios监控Memcached服务

说到Memcached服务,其实作为运维人员用的还是很多的: 1.在做LB的时候,为了保证同一台机器的请求的session信息防止丢失,我们用Memcached对session做分布式存储. 2.做mysql缓存的时候,我们常常吧mysql查询的结果缓存到Memcached中,这样能够较少php程序与mysql的交互,也能大大减轻数据库的压力. 从以上来看,Memcached其实也是蛮重要的,那么我们更有必要对其进行时刻的监控,接下来引入正题 Nagios监控Memcached服务是否正常运行.

Memcached的安装与使用

Windows下的Memcache安装 1. 下载memcache的windows稳定版,解压放某个盘下面,比如在c:\memcached 2. 在终端(也即cmd命令界面)下输入 c:\memcached\memcached.exe -d install            --安装memcached成为服务,这样才能正常运行,否则运行失败! 3. 再输入: c:\memcached\memcached.exe -d start    --启动memcached的. 以后memcached将
