# personal-servers How I put my very own personal servers online, for free. Details at [the blog post](http://ralsina.me/weblog/posts/the-cheapest-server.html) When adding a new hostname, remember to create a cert for it using `flyctl certs create hostname` Every 90 days the tailscale auth key will expire and you need to set a new one as a secret. * Create the new one at https://login.tailscale.com/admin/settings/keys (MAKE IT REUSABLE) * Configure it using flyctl secrets set TAILSCALE_AUTHKEY={{PASTEKEYHERE}}
