HAPROXY

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 http://dagobah.ftphosting.net/yum/SRPMS/haproxy-1.5-dev14.src.rpm

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 host.domain.com:8000 check

Restart HAProxy and enjoy!

Cleanup:

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

Notes:

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.
