    cd memcached-2.2.0
    /usr/local/php/bin/phpize
    ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcached --with-libmemcached-dir=/usr/local/libmemcached

#
    /etc/init.d/php-fpm restart
    rm -rf phpredis-develop/ && sleep 1

    if [ ! -e "$ext_dir/memcached.so" ];then
        echo -e "\033[31merror! can't install memcached.so! \033[0m"
        exit 1
