Use HAProxy 1.5 to create an SSL reverse proxy

If you're working from an existing install, you will likely need to remove HAProxy 1.4 before continuing. Be sure to take a backup of /etc/haproxy/haproxy.cfg!

yum erase haproxy

We are going to build HAProxy from a source rpm, so we need to install a few things:

yum install @development openssl-devel pcre-static pcre-devel

Then we download a source rpm to build from:

curl -O

Then we build the rpm:

rpmbuild --rebuild haproxy-1.5-dev14.src.rpm

Then we install the rpm we just built:

rpm -Uvh rpmbuild/RPMS/x86_64/haproxy-1.5-dev14.x86_64.rpm

Let's move the original config back in place:

mv /etc/haproxy/haproxy.cfg.rpmsave /etc/haproxy/haproxy.cfg

Let's make a directory for the cert/s:

mkdir -p /etc/haproxy/certs

Put your pem cert/key into the certs folder:

mv certificate.pem /etc/haproxy/certs

Add the following to the /etc/haproxy/haproxy.cfg config:

frontend whapps-ssl-in
    bind *:8443 ssl crt /etc/haproxy/certs/certificate.pem
    default_backend whapps
backend whapps
    balance roundrobin
    server localhost check

Restart HAProxy and enjoy!


Update the /var/www/html/config/config.js for the new https: and port

You may need to update the endpoint entries for existing users to point to the new https: and port, you can see how to do that here:

Manually Editing Database Documents#


If you have an existing cert, ca-bundle and key, here's how you can make the pem:

cat certificate.crt ca-bundle.crt private.key > certificate.pem

Hopefully it's obvious that the paths, and host names need to be updated for your environment.
