CentOS 6.2 安装memcached

yum 安装(memcached可能不是最新的)
1. 打开终端，切换到root用户
2. 安装libevent 
     yum install libevent

3. 安装memcached
     yum install memcached

memcached源代码安装：
1. 下载软件

      memcached最新版 (http://memcached.googlecode.com/files/memcached-1.4.13.tar.gz)

      libevent（memcached依赖libvent）最新稳定版 (http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.18-stable.tar.gz)

      并将它们copy到/tmp

2. 安装

    2.1 打开终端，切换到root用户，先安装libevent(memcached依赖libevent）
          cd /tmp
          tar -zxvf libevent-2.0.18-stable.tar.gz
          cd libevent-2.0.18-stable
          ./configure –prefix=/usr
          make
          make install

          检查libevent是否安装成功（ls -al /usr/lib|grep libevent）

     2.2 安装memcached，需要指定libevent的安装位置.
          cd /tmp
          tar -zxvf memcached-1.4.13.tar.gz
          cd memcached-1.4.13
          ./configure --with-libevent=/usr --prefix=/usr/local/bin/memcached
          make
          make install
         
          测试是否成功安装memcached：
          ls -al /usr/local/bin/mem*

启动Memcache的服务器
    1.  /usr/local/bin/memcached/bin/memcached -d -m 10 -u jmbkeyes -c 256 -p 11211 -P /tmp/memcached.pid
            -d选项是启动一个守护进程，
            -m是分配给Memcache使用的内存数量，单位是MB，这里是10MB，
        　 -u是运行Memcache的用户，这里是root，
　　     -l是监听的服务器IP地址，
　　     -p是设置Memcache监听的端口，这里设置11211，最好是1024以上的端口，
　　     -c选项是最大运行的并发连接数，默认是1024，这里设置256，按照服务器的负载量来设定，
　 　    -P是设置保存Memcache的pid文件，现保存在 /tmp/memcached.pid，
     2.  结束Memcache进程，执行：
            kill `cat /tmp/memcached.pid`
测试Memcached
     telnet 127.0.0.1 11211
        Trying 127.0.0.1...
        Connected to 127.0.0.1.
        Escape character is '^]'.
        set key1 0 60 4
        testing
        STORED
        set key1
        VALUE key1 0 4
        testing
        END
