## TiProxy

When using TiProxy in front of a set of TiDB servers you also need to configure TLS for it.

Depending on the `TiProxyCertLayout` a different certificate layout is chosen:

- not set: This is the legacy layout.
- `v1`: This is version one of the layout. This is recommended.

There are TLS settings for these components of TiProxy:

- `security.cluster-tls`: used to interface with other hosts in the cluster both as server and client (mTLS).
- `security.server-tls`: used for serving MySQL protocol access on port 6000.
- `security.sql-tls`: used to access TiDB as a client.
- `security.server-http-tls` used to serve HTTP services on port 3080.

See also [the security section of the configuration](https://docs.pingcap.com/tidb/stable/tiproxy-configuration/#security).

TiProxy will try to use the TLS secret from TiDB for client/server connections by default. If you do this make sure these certificates also contain the hostname of the TiProxy hosts.

Other settings that influence this:

- `tlsCluster.enabled`
- `tlsClient.enabled`

The certificates can be generated with cfssl or cert-manager.
