# An ACME Shell script: acme.sh
|
|
- An ACME protocol client written purely in Shell (Unix shell) language.
|
|
- Fully ACME protocol implementation.
|
|
- Simple, powerful and very easy to use. You only need 3 minutes to learn.
|
|
- Bash, dash and sh compatible.
|
|
- Simplest shell script for Let's Encrypt free certificate client.
|
|
- Purely written in Shell with no dependencies on python or Let's Encrypt official client.
|
|
- Just one script, to issue, renew and install your certificates automatically.
|
|
- DOES NOT require `root/sudoer` access.
|
|
|
|
It's probably the `easiest&smallest&smartest` shell script to automatically issue & renew the free certificates from Let's Encrypt.

# Upgrade from 1.x to 2.x
|
|
|
|
You can simply uninstall 1.x and re-install 2.x.
|
|
2.x is 100% compatible to 1.x. You will feel right at home as if nothing has changed.
|
|
|
|
# le.sh renamed to acme.sh NOW!
|
|
|
|
All configurations are 100% compatible between `le.sh` and `acme.sh`. You just need to uninstall `le.sh` and re-install `acme.sh` again.
|
|
Nothing will be broken during the process.

# How to install
|
|
|
|
### 1. Install online:
|
|
|
|
Check this project: https://github.com/Neilpang/get.acme.sh
|
|
|
|
```bash
|
|
curl https://get.acme.sh | sh
|
|
|
|
```
|
|
|
|
Or:
|
|
|
|
```bash
|
|
wget -O - https://get.acme.sh | sh
|
|
|
|
```
|
|
|
|
|
|
### 2. Or, Install from git:
|
|
|
|
Clone this project:
|
|
|
|
```bash
|
|
git clone https://github.com/Neilpang/acme.sh.git
|
|
cd ./acme.sh
|
|
./acme.sh --install
|
|
```
|
|
|
|
You `don't have to be root` then, although `it is recommended`.
|
|
|
|
Advanced Installation: https://github.com/Neilpang/acme.sh/wiki/How-to-install
|
|
|
|
The installer will perform 3 actions:
|
|
|
|
1. Create and copy `acme.sh` to your home dir (`$HOME`): `~/.acme.sh/`.
|
|
All certs will be placed in this folder.
|
|
2. Create alias for: `acme.sh=~/.acme.sh/acme.sh`.
|
|
3. Create everyday cron job to check and renew the cert if needed.
|
|
|
|
Cron entry example:
|
|
|
|
```bash
|
|
0 0 * * * "/home/user/.acme.sh"/acme.sh --cron --home "/home/user/.acme.sh" > /dev/null
|
|
```
|
|
|
|
After the installation, you must close current terminal and reopen again to make the alias take effect.
|
|
|
|
Ok, you are ready to issue cert now.
|
|
Show help message:
|
|
|
|
```
|
|
|
|
root@v1:~# acme.sh -h
|
|
|
|
```
|
|
|
|
# Just issue a cert:
|
|
|
|
**Example 1:** Single domain.
|
|
|
|
```bash
|
|
acme.sh --issue -d aa.com -w /home/wwwroot/aa.com
|
|
```
|
|
|
|
**Example 2:** Multiple domains in the same cert.
|
|
|
|
```bash
|
|
acme.sh --issue -d aa.com -d www.aa.com -d cp.aa.com -w /home/wwwroot/aa.com
|
|
```
|
|
|
|
The parameter `/home/wwwroot/aa.com` is the web root folder. You **MUST** have `write access` to this folder.
|
|
|
|
Second argument **"aa.com"** is the main domain you want to issue cert for.
|
|
You must have at least a domain there.
|
|
|
|
You must point and bind all the domains to the same webroot dir: `/home/wwwroot/aa.com`.
|
|
|
|
Generate/issued certs will be placed in `~/.acme.sh/aa.com/`
|
|
|
|
The issued cert will be renewed every 80 days automatically.
|
|
|
|
More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
|
|
|
|
|
|
# Install issued cert to apache/nginx etc.
|
|
|
|
After you issue a cert, you probably want to install the cert with your nginx/apache or other servers you may be using.
|
|
|
|
```bash
|
|
acme.sh --installcert -d aa.com \
|
|
--certpath /path/to/certfile/in/apache/nginx \
|
|
--keypath /path/to/keyfile/in/apache/nginx \
|
|
--capath /path/to/ca/certfile/apache/nginx \
|
|
--fullchainpath path/to/fullchain/certfile/apache/nginx \
|
|
--reloadcmd "service apache2|nginx reload"
|
|
```
|
|
|
|
Only the domain is required, all the other parameters are optional.
|
|
|
|
Install the issued cert/key to the production apache or nginx path.
|
|
|
|
The cert will be `renewed every 80 days by default` (which is configurable). Once the cert is renewed, the apache/nginx will be automatically reloaded by the command: `service apache2 reload` or `service nginx reload`.
|
|
|
|
# Use Standalone server to issue cert
|
|
|
|
**(requires you be root/sudoer, or you have permission to listen tcp 80 port)**
|
|
|
|
The tcp `80` port **MUST** be free to listen, otherwise you will be prompted to free the `80` port and try again.
|
|
|
|
```bash
|
|
acme.sh --issue --standalone -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 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)**
|
|
|
|
If you are running a web server, apache or nginx, it is recommended to use the `Webroot mode`.
|
|
|
|
Particularly, if you are running an apache server, you should use apache mode instead. This mode doesn't write any files to your web root folder.
|
|
|
|
Just set string "apache" as the second argument, it will force use of apache plugin automatically.
|
|
|
|
```
|
|
acme.sh --issue --apache -d aa.com -d www.aa.com -d user.aa.com
|
|
```
|
|
|
|
More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
|
|
|
|
# Use DNS mode:
|
|
|
|
Support the `dns-01` challenge.
|
|
|
|
```bash
|
|
acme.sh --issue --dns -d aa.com -d www.aa.com -d user.aa.com
|
|
```
|
|
|
|
You should get the output like below:
|
|
|
|
```
|
|
Add the following txt record:
|
|
Domain:_acme-challenge.aa.com
|
|
Txt value:9ihDbjYfTExAYeDs4DBUeuTo18KBzwvTEjUnSwd32-c
|
|
|
|
Add the following txt record:
|
|
Domain:_acme-challenge.www.aa.com
|
|
Txt value:9ihDbjxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
|
|
|
|
Please add those txt records to the domains. Waiting for the dns to take effect.
|
|
|
|
```
|
|
|
|
Then just rerun with `renew` argument:
|
|
|
|
```bash
|
|
acme.sh --renew -d aa.com
|
|
```
|
|
|
|
Ok, it's finished.
|
|
|
|
# Automatic DNS API integration
|
|
|
|
If your DNS provider supports API access, we can use API to automatically issue the certs.
|
|
|
|
You don't have do anything manually!
|
|
|
|
### Currently acme.sh supports:
|
|
|
|
1. Cloudflare.com API
|
|
2. Dnspod.cn API
|
|
3. Cloudxns.com API
|
|
4. AWS Route 53, see: https://github.com/Neilpang/acme.sh/issues/65
|
|
5. lexicon dns api: https://github.com/Neilpang/acme.sh/wiki/How-to-use-lexicon-dns-api
|
|
(DigitalOcean, DNSimple, DnsMadeEasy, DNSPark, EasyDNS, Namesilo, NS1, PointHQ, Rage4 and Vultr etc.)
|
|
|
|
##### More APIs are coming soon...
|
|
|
|
If your DNS provider is not on the supported list above, you can write your own script API easily. If you do please consider submitting a [Pull Request](https://github.com/Neilpang/acme.sh/pulls) and contribute to the project.

# Issue ECC certificate:
|
|
|
|
`Let's Encrypt` now can issue **ECDSA** certificates.
|
|
|
|
And we also support it.
|
|
|
|
Just set the `length` parameter with a prefix `ec-`.
|
|
|
|
For example:
|
|
|
|
### Single domain ECC cerfiticate:
|
|
|
|
```bash
|
|
acme.sh --issue -w /home/wwwroot/aa.com -d aa.com --keylength ec-256
|
|
```
|
|
|
|
SAN multi domain ECC certificate:
|
|
|
|
```bash
|
|
acme.sh --issue -w /home/wwwroot/aa.com -d aa.com -d www.aa.com --keylength ec-256
|
|
```
|
|
|
|
Please look at the last parameter above.
|
|
|
|
Valid values are:
|
|
|
|
1. **ec-256 (prime256v1, "ECDSA P-256")**
|
|
2. **ec-384 (secp384r1, "ECDSA P-384")**
|
|
3. **ec-521 (secp521r1, "ECDSA P-521", which is not supported by Let's Encrypt yet.)**
|
|
|
|
# Under the Hood
|
|
|
|
Speak ACME language using shell, directly to "Let's Encrypt".
