Upgrade your key server

Periodically, you may need to update your key server when using Cloudflare's Keyless SSL.

To upgrade your key server:

1. Back up the contents of /etc/keyless.
2. Update your OS’ package listings, for example, apt-get update or yum update.
3. Upgrade the gokeyless server:
4. Debian/Ubuntu: apt-get upgrade gokeyless
5. RHEL/CentOS: yum install gokeyless
6. Restart the keyless instance:
7. systemd: service gokeyless restart
8. upstart/sysvinit: /etc/init.d/gokeyless restart
9. Confirm that HTTPS connections are working as expected.

Warning

If you are running a high availability configuration, upgrade one server at a time as new TLS connections will fail to terminate at Cloudflare's global network without a functioning key server.
