Managing SSL certificates for MySQL can be somewhat of a pain, especially when setting it up on multiple machines.

I looked around on the web, and didn’t really run into any mentions of how to do this for multiple machines, so I dug into it a bit more.

cd C:\mysql\certs
openssl genrsa 2048 > ca-key.pem
openssl req -new -x509 -nodes -days 3600 -batch -key ca-key.pem > ca-cert.pem
openssl req -newkey rsa:2048 -days 3600 -batch -nodes -keyout server-key.pem >
        server-req.pem
openssl x509 -req -in server-req.pem -days 3600 -CA ca-cert.pem
        -CAkey …
