# tar -xzf libevent-1.1a.tar.gz
# cd libevent-1.1a
# ./configure --prefix=/usr
# make
# make install

/usr/bin/memcached -d -m 256 -l 192.168.1.1 -p 11211 -u www


/usr/bin/memcached -d -m 128 -p 11211 -u www


参数解释：

-d 以守护程序（daemon）方式运行 memcached；
-m 设置 memcached 可以使用的内存大小，单位为 M；
-l 设置监听的 IP 地址，如果是本机的话，通常可以不设置此参数；
-p 设置监听的端口，默认为 11211，所以也可以不设置此参数；
-u 指定用户，如果当前为 root 的话，需要使用此参数指定用户
