# Consul TLS Cert Create
|
|
|
|
Command: `consul tls cert create`
|
|
|
|
The `tls cert create` command is used to create certificates for your Consul TLS
|
|
setup.
|
|
|
|
## Examples
|
|
|
|
Create a certificate for servers:
|
|
|
|
```shell-session
|
|
$ consul tls cert create -server
|
|
==> WARNING: Server Certificates grants authority to become a
|
|
server and access all state in the cluster including root keys
|
|
and all ACL tokens. Do not distribute them to production hosts
|
|
that are not server nodes. Store them as securely as CA keys.
|
|
==> Using consul-ca.pem and consul-ca-key.pem
|
|
==> Saved dc1-server-consul-0.pem
|
|
==> Saved dc1-server-consul-0-key.pem
|
|
```
|
|
|
|
Create a certificate for clients:
|
|
|
|
```shell-session
|
|
$ consul tls cert create -client
|
|
==> Using consul-ca.pem and consul-ca-key.pem
|
|
==> Saved consul-client-0.pem
|
|
==> Saved consul-client-0-key.pem
|
|
```
|
|
|
|
Create a certificate for cli:
|
|
|
|
```shell-session
|
|
$ consul tls cert create -cli
|
|
==> Using consul-ca.pem and consul-ca-key.pem
|
|
==> Saved consul-cli-0.pem
|
|
==> Saved consul-cli-0-key.pem
|
|
```
|
|
|
