lighttpd如何打patch

我是这样打的补丁:
patching steps:
tar xfz lighttpd-1.4.19.tar.gz
cd lighttpd-1.4.19
wget http://blog.quehy.com/doc/lighttpd-1.4.19.mod_mem_cache.patch
(也就是在你安装lighttpd-1.4.19的目录下,下载补丁)

patch -p0 < lighttpd-1.4.19.mod_mem_cache.patch
sh autogen.sh
./configure prefix=/usr/local/lighttpd;
make
make install

OK ls /usr/local/lighttpd/lib/发现出现了mod_mem_cache
