本文只是记录编译nghttp2所遇到的问题的解决方法，具体步骤请看这里（十分详细）。

1、nghttp2依赖spdylay，安装spdylay后，运行spdycat提示：

spdycat: error while loading shared libraries: libspdylay.so.7: cannot open shared object file: No such file or directory

然后ldd `which spdycat`，会发现缺少运行库libspdylay.so.7

ldd `which spdycat`
	linux-vdso.so.1 =>  (0x00007fffced6e000)
	libssl.so.1.0.0 => /lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007ff963dff000)
	libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007ff963a24000)
	libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 (0x00007ff9636bd000)
	libspdylay.so.7 => not found
	libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007ff9633b9000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007ff9631a2000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007ff962f84000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff962bbf000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007ff9629ba000)
	libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007ff9627a1000)
	liblzma.so.5 => /lib/x86_64-linux-gnu/liblzma.so.5 (0x00007ff96257f000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007ff962278000)
	/lib64/ld-linux-x86-64.so.2 (0x00007ff964066000)

运行find /usr/local -name libspdylay.so

/usr/local/lib/libspdylay.so

创建libspdylay.so的软链接，再次运行spdycat，无错误返回即可

sudo ln -s /usr/local/lib/libspdylay.so /lib/x86_64-linux-gnu/libspdylay.so.7

2、nghttp2同样会遇到缺运行库的错误，同样地ln -s

sudo ln -s /usr/local/lib/libnghttp2.so /lib/x86_64-linux-gnu/libnghttp2.so.5
nghttpx
Usage: nghttpx [OPTIONS]... [<PRIVATE_KEY> <CERT>]
A reverse proxy for HTTP/2, HTTP/1 and SPDY.
01/Apr/2015:00:20:13 +0800 PID14428 [FATAL] shrpx.cc:1999 Too few arguments

至此，编译、安装部分完成。

3、Chrome连接nghttp2 proxy时报spdy错误
“Error code:ERR_SPDY_PROTOCOL_ERROR”,这是Chrome的BUG，只需要把nghttpx协商的优先顺序改为spdy/3.1即可

sudo nghttpx -s -f0.0.0.0,443 -b127.0.0.1,8080 \
/etc/nghttpx/certs/ssl.key /etc/nghttpx/certs/ssl.crt \
--npn-list=spdy/3.1,h2
