安装libevent和memcache
tar zxvf libevent-1.4.13-stable.tar.gz
cd libevent-1.4.13-stable
./configure –prefix=/usr
make
make install
安装memcached，同时需要安装中指定libevent的安装位置
tar zxvf memcached-1.4.4.tar.gz
cd memcached-1.4.4
./configure –with-libevent=/usr
make && make install
安装完成后会把memcached 自动放到 /usr/local/bin/memcached
4、测试是否成功安装memcached
ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 201869 12-14 21:44 /usr/local/bin/memcached
