After thinking a bit about my server configuration I realized that using a reverse proxy kinda eliminates the pupose of using gatling in the first place -.-‘


So I set out to install gatling with ssl enabled.

After searching for a bit I found this message here. The important part is this:

This is how I did it:

./config --prefix=/opt/diet no-dso
make CC="diet -Os gcc -pipe -nostdinc"

make install will then install to /opt/diet/lib, which is on my box a symlink to /opt/diet/lib-i386.

After another

make install

I tried compiling tlsgatling again just to realize that I still hat the openssl-devel package installed. So after uninstalling that and symlinking

ln -s /opt/diet/lib/libcrypto.a /lib64/.
ln -s /opt/diet/lib/libssl.a /lib64/.
ln -s /opt/diet/include/openssl/ /usr/local/include/.

Compiling worked fine. Finally I have a working tlsgatling

NOTE I don’t reccommend doing the above symlinks… I think that may break something ツ

Finally I moved tlsgatling to /opt/diet/bin


For my certificate I used letsencrypt. The HowTo tells me I need to do the following:

./letsencrypt-auto certonly --standalone -d -d

Which didn’t work… I first needed to shutdown my webserver than I needed to disable my special firewall rules. Or to be more specific I needed to add some rules to my firewall

firewall-cmd --add-rule=http --zone=public
firewall-cmd --add-rule=https --zone=public
firewall-cmd --add-rule=http --permanent --zone=public
firewall-cmd --add-rule=https --permanent --zone=public

(not sure if http is needed but I didn’t care)

After running the letsencrypt command again I had my certificate. If I want to use it I need to concatenate the privkey.pem and cert.pem files

cat /etc/letsencrypt/live/ /etc/letsencrypt/live/ >server.pem

This file needs to be moved to /var/www and need to be change to world unreadable

chmod o-r server.pem

I modified my gatling.service file to the following:

Now i can run

systemctl daemon-reload && systemctl start gatling.service

and have a running ssl enabled webserver
