Re: [users@httpd] Apache HTTP2 and benchmarking with h2load

Max Meyer Thu, 25 Aug 2016 09:21:52 -0700

The webserver is Ubuntu 14.04

I used the ppa from Ondřej Surý for the apache installation.


https://launchpad.net/~ondrej/+archive/ubuntu/apache2

The client is Linux Mint 17.3 (which is basically Ubuntu 14.04).

For h2load I built nghttp2 from source:

git clone https://github.com/tatsuhiro-t/nghttp2.git
cd nghttp2
autoreconf -i
automake
autoconf
./configure
make
sudo make install

For testing purposes I just built nghttp2 on the server (the same way Idid on the client), started h2load and here it works without fallingback to http/1.1

Ok, both clients do not provide the server name via the TLS SNI extension. That 
is strange. How did you get the server/h2load installed on your Ubuntu? Default 
Ubuntu comes without mod_http2 AFAIK...(and which Ubuntu is it?) Thanks!

I created a new certificate, now the cert name matches but h2load still falls 
back to HTTP/1.1

Here is the error.log after apache restart
