# Use Standalone tls server to issue cert
**(requires you be root/sudoer, or you have permission to listen tcp 443 port)**
acme.sh supports `tls-sni-01` validation.
The tcp `443` port **MUST** be free to listen, otherwise you will be prompted to free the `443` port and try again.
```bash
acme.sh --issue --tls -d aa.com -d www.aa.com -d cp.aa.com
```
More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
# Use Apache mode
**(requires you be root/sudoer, since it is required to interact with apache server)**
