memcached make: *** No targets specified and no makefile found. Stop.

其实是因为在安装libevent时增加了版本号导致的，所以注意在安装libevent时不要增加版本号

1.rpm -qa|grep libevent
查看系统是否带有该安装软件，如果有执行命令:

rpm -e libevent-1.4.13-4.el6.i686 --nodeps（由于系统自带的版本旧，忽略依赖删除）

2. 安装libevent命令： (https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz)
tar zxvf libevent-2.0.21-stable.tar.gz
 cd libevent-2.0.21-stable
 ./configure --prefix=/usr
make
make install
至此libevent安装完毕

在 php-memcached官网发现有最新的版本3.0.3 stable版本，安装几次没有成功，总提示

php的扩展memcache，不支持cas，所以我们要装memcached扩展，memcached扩展是基于libmemcached，所以要先安装libmemcached

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
tar zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure --prefix=/usr/local/libmemcached --with-memcached
make
make install

checking for libevent directory... configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/

If it's already installed, specify its path using --with-libevent=/dir/

提示需要libevent，需要指明libevent的安装目录

memcached 依赖于 libevent 库,因此我们需要先安装 libevent.，ibevent和memcached的下载路径
