+
+## 四、本地docker部署
+
+### 1. 安装docker、docker-compose
+
+1.1 准备一台云服务器
+* 【阿里云】云服务器2核2G，新老用户同享，99元/年，续费同价！【 [立即购买](https://www.aliyun.com/benefit?scm=20140722.M_10244282._.V_1&source=5176.11533457&userCode=qya11txb )】
+* 【腾讯云】云服务器2核2G，新老用户同享，99元/年，续费同价！【 [立即购买](https://cloud.tencent.com/act/cps/redirect?redirect=6094&cps_key=b3ef73330335d7a6efa4a4bbeeb6b2c9&from=console)】
+  
+
+1.2 安装docker    
+https://docs.docker.com/engine/install/
+选择对应的操作系统，按照官方文档执行命令即可
+
+
+### 2. 下载docker-compose.yaml文件
+
+[docker-compose.yaml下载](https://gitee.com/certd/certd/raw/v2/docker/run/docker-compose.yaml)
+
+```bash
+mkdir certd
+cd certd
+# wget下载docker-compose.yaml文件
+wget https://raw.githubusercontent.com/certd/certd/v2/docker/run/docker-compose.yaml
+# 或者使用gitee地址
+wget https://gitee.com/certd/certd/raw/v2/docker/run/docker-compose.yaml
+
+# 根据需要修改里面的配置
+# 1.修改镜像版本号【可选】
+# 2.配置数据保存路径【可选】
+# 3.配置certd_auth_jwt_secret【必须】
+vi docker-compose.yaml
+
+
+```
+> 镜像版本号与release版本号同步：    
+https://github.com/certd/certd/releases
+
+
+### 3. 运行
+```bash
+# 如果docker compose是插件化安装
+export CERTD_VERSION=latest
+docker compose up -d
+```
+如果提示 没有compose命令,请安装docker-compose   
+https://docs.docker.com/compose/install/linux/
+
+
+
+### 4. 访问
+
+http://your_server_ip:7001 
+默认账号密码：admin/123456 
+记得修改密码
+
+
+### 5. 升级
+
+* 修改版本号，重新运行 `docker compose up -d` 即可
+* 数据存在`/data/certd`目录下，不用担心数据丢失
+
+
+
+## 五、一些说明
 * 本项目ssl证书提供商为letencrypt
 * 申请过程遵循acme协议
-* 需要验证域名所有权，一般有两种方式（目前本项目仅支持dns-01）      
-  * http-01： 在网站根目录下放置一份txt文件     
-  * dns-01： 需要给域名添加txt解析记录，泛域名只能用这种方式   
+* 需要验证域名所有权，一般有两种方式（目前本项目仅支持dns-01）
+  * http-01： 在网站根目录下放置一份txt文件
+  * dns-01： 需要给域名添加txt解析记录，通配符域名只能用这种方式
 * 证书续期：
  * 实际上acme并没有续期概念。
  * 我们所说的续期，其实就是按照全套流程重新申请一份新证书。
 * 免费证书过期时间90天，以后可能还会缩短，所以自动化部署必不可少
+* 设置每天自动运行，当证书过期前20天，会自动重新申请证书并部署
+
+## 六、不同平台的设置说明

-## 快速开始
-本案例演示，如何配置自动申请证书，并部署到阿里云CDN，然后快要到期前自动更新证书并重新部署    
-
-
-1. 环境准备   
-安装[nodejs](https://nodejs.org/zh-cn/)
-
-
-2. 生成node项目
-
-  通过ui生成： https://certd.docmirror.cn/
-  
-开始生成证书，先填写域名，支持将多个域名打到一个证书上
-![](./doc/step1.png)
-
-配置证书详细信息
-![](./doc/step2.png)
-
-配置证书部署流程
-![](./doc/step3.png)
-
-配置好之后，点击导出按钮，导出一个node项目包
-
-4. 运行    
-将导出的压缩包解压，然后执行如下命令，即可开始申请证书并部署
+## 七、问题处理
+### 7.1 忘记管理员密码   
+解决方法如下：
+1. 修改docker-compose.yaml文件，将环境变量`certd_system_resetAdminPassword`改为`true`
+```yaml
+services:
+  certd:
+    environment: # 环境变量
+      - certd_system_resetAdminPassword=false
 ```
-npm install
-npm run certd
+2. 重启容器
+```shell
+docker compose up -d
+docker logs -f --tail 500 certd
+# 观察日志，当日志中输出“重置1号管理员用户的密码完成”，即可操作下一步
 ```
-5. 执行效果
-生成的证书默认会存储在 `${home}/.certd/${email}/certs/${domain}/current`目录下 
+3. 修改docker-compose.yaml，将`certd_system_resetAdminPassword`改回`false`
+4. 再次重启容器
+```shell
+docker compose up -d

-6. 证书续期    
-实际上没有证书续期的概念，只有重新生成一份新的证书，然后重新部署证书    
-所以每天定时运行即可，当证书过期日前20天时，会重新申请新的证书，然后执行部署任务。     
+5. 使用admin/123456登录系统，请及时修改管理员密码

-7. 其他说明    
-证书的部署任务执行后会记录执行结果，已经成功过的不会重复执行     
-所以当你临时需要将证书部署到其他地方时，直接追加部署任务，然后再次运行即可
-
-## CI/DI集成与自动续期重新部署
-集成前，将以上导出的node项目提交到内网git仓库，或者私有git仓库（由于包含敏感信息，不要提交到公开git仓库）
-
-### jenkins任务
-1. 创建任务     
-选择构建自由风格的任务     
-
-2. 配置git    
-配置cert-run的git地址     
-
-3. 构建触发器    
-配置 `H 3 * * *` ，每天凌晨3点-4点执行一次
-
-4. 构建环境    
-勾选 `Provide Node & npm bin/ folder to PATH`，提供nodejs运行环境     
-如果没有此选项，需要jenkins安装`nodejs`插件
-
-5. 构建    
-执行shell
-```
-npm install --production   #执行过一次之后，就可以注释掉，加快执行速度
-npm run post
-```
-6. 构建后操作     
-邮件通知   
-配置你的邮箱地址，可以在执行失败时收到邮件通知。

 # Changelog

-## Important upgrade notice
+## v5.3.1 (2024-05-22)

-On September 15, 2022, Let's Encrypt will stop accepting Certificate Signing Requests signed using the obsolete SHA-1 hash. This change affects all `acme-client` versions lower than `3.3.2` and `4.2.4`. Please upgrade ASAP to ensure that your certificates can still be issued following this date.
+* `fixed` Allow `client.auto()` being called with an empty CSR common name
+* `fixed` Bug when calling `updateAccountKey()` with external account binding

-A more detailed explanation can be found [at the Let's Encrypt forums](https://community.letsencrypt.org/t/rejecting-sha-1-csrs-and-validation-using-tls-1-0-1-1-urls/175144).
+## v5.3.0 (2024-02-05)
+
+* `added` Support and tests for satisfying `tls-alpn-01` challenges
+* `changed` Replace `jsrsasign` with `@peculiar/x509` for certificate and CSR generation and parsing
+* `changed` Method `getChallengeKeyAuthorization()` now returns `$token.$thumbprint` when called with a `tls-alpn-01` challenge
+    * Previously returned base64url encoded SHA256 digest of `$token.$thumbprint` erroneously
+    * This change is not considered breaking since the previous behavior was incorrect
+
+## v5.2.0 (2024-01-22)
+
+* `fixed` Allow self-signed or invalid certs when validating `http-01` challenges that redirect to HTTPS - [#65](https://github.com/publishlab/node-acme-client/issues/65)
+* `fixed` Wait for all challenge promises to settle before rejecting `client.auto()` - [#75](https://github.com/publishlab/node-acme-client/issues/75)
+
+## v5.1.0 (2024-01-20)

-On September 15, 2022, Let's Encrypt will stop accepting Certificate Signing Requests signed using the obsolete SHA-1 hash. This change affects all `acme-client` versions lower than `3.3.2` and `4.2.4`. Please upgrade ASAP to ensure that your certificates can still be issued following this date.

 });
 ```

-
 ### Legacy `.forge` interface

 The legacy `node-forge` crypto interface is still available for backward compatibility, however this interface is now considered deprecated and will be removed in a future major version of `acme-client`.

 You should consider migrating to the new `.crypto` API at your earliest convenience. More details can be found in the [acme-client v5 upgrade guide](docs/upgrade-v5.md).

 ## Auto mode

 For convenience an `auto()` method is included in the client that takes a single config object. This method will handle the entire process of getting a certificate for one or multiple domains.

-
 ### Challenge priority

 When ordering a certificate using auto mode, `acme-client` uses a priority list when selecting challenges to respond to. Its default value is `['http-01', 'dns-01']` which translates to "use `http-01` if any challenges exist, otherwise fall back to `dns-01`".

-While most challenges can be validated using the method of your choosing, please note that __wildcard certificates can only be validated through `dns-01`__. More information regarding Let's Encrypt challenge types [can be found here](https://letsencrypt.org/docs/challenge-types/).

 First off this release drops support for Node LTS v10, v12 and v14, and the reason for that is a new native crypto interface - more on that below. Since Node v14 is still currently in maintenance mode, `acme-client` v4 will continue to receive security updates and bugfixes until (at least) Node v14 reaches its end-of-line.

 ## New native crypto interface

-A new crypto interface has been introduced with v5, which you can find under `acme.crypto`. It uses native Node.js cryptography APIs to generate private keys, JSON Web Keys and signatures, and finally enables support for ECC/ECDSA (P-256, P384 and P521), both for account private keys and certificates. The [jsrsasign](https://www.npmjs.com/package/jsrsasign) module is used to handle generation and parsing of Certificate Signing Requests.

+These examples should not be used as is for any production environment, as they are just proof of concepts meant for testing and to get you started. The examples are naively written and purposefully avoids important topics since they will be specific to your application and how you choose to use `acme-client`, like for example:
+
+1. **Concurrency control**
+    * If implementing on-demand certificate generation
+    * What happens when multiple requests hit your domain at the same time?
+    * Ensure your application does not place multiple cert orders for the same domain at the same time by implementing some sort of exclusive lock
+2. **Domain allow lists**
+    * If implementing on-demand certificate generation
+    * What happens when someone manipulates the `ServerName` or `Host` header to your service?
+    * Ensure your application is unable to place certificate orders for domains you do not intend, as this can quickly rate limit your account and cause a DoS
+3. **Clustering**
+    * If using `acme-client` across a cluster of servers
+    * Ensure challenge responses are known to all servers in your cluster, perhaps using a database or shared storage
+4. **Certificate and key storage**
+    * Where and how should the account key be stored and read?
+    * Where and how should certificates and cert keys be stored and read?
+    * How and when should they be renewed?

+# dns-01
+
+The greatest benefit of `dns-01` is that it is the only challenge type that can be used to issue ACME wildcard certificates, however it also has a few downsides. Your DNS provider needs to offer some sort of API you can use to automate adding and removing the required `TXT` DNS records. Additionally, solving DNS challenges will be much slower than the other challenge types because of DNS propagation delays.
+
+## How it works
+
+When solving `dns-01` challenges, you prove ownership of a domain by serving a specific payload within a specific DNS `TXT` record from the domains authoritative nameservers. The ACME authority provides the client with a token that, along with a thumbprint of your account key, is used to generate a `base64url` encoded `SHA256` digest. This payload is then placed as a `TXT` record under DNS name `_acme-challenge.$YOUR_DOMAIN`.
+
+Once the order is finalized, the ACME authority will lookup your domains DNS record to verify that the payload is correct. `CNAME` and `NS` records are followed, should you wish to delegate challenge response to another DNS zone or record.
+
+## Pros and cons
+
+* Only challenge type that can be used to issue wildcard certificates
+* Your DNS provider needs to supply an API that can be used
+* DNS propagation time may be slow
+* Useful in instances where both port 80 and 443 are unavailable

+When solving `http-01` challenges, you prove ownership of a domain name by serving a specific payload from a specific URL. The ACME authority provides the client with a token that is used to generate the URL and file contents. The file must exist at `http://$YOUR_DOMAIN/.well-known/acme-challenge/$TOKEN` and contain the token and a thumbprint of your account key.
+
+Once the order is finalized, the ACME authority will verify that the URL responds with the correct payload by sending HTTP requests before the challenge is valid. HTTP redirects are followed, and Let's Encrypt allows redirecting to HTTPS although this diverges from the ACME spec.
+
+## Pros and cons
+
+* Challenge must be satisfied using port 80 (HTTP)
+* The simplest challenge type to implement
+* Can not be used to issue wildcard certificates
+* If using multiple web servers, all of them need to respond with the correct token

+# tls-alpn-01
+
+Responding to `tls-alpn-01` challenges using Node.js is a bit more involved than the other two challenge types, and requires a proxy (f.ex. [Nginx](https://nginx.org) or [HAProxy](https://www.haproxy.org)) in front of the Node.js service. The reason for this is that `tls-alpn-01` is solved by responding to the ACME challenge using self-signed certificates with an ALPN extension containing the challenge response.
+
+Since we don't want users of our application to be served with these self-signed certificates, we need to split the HTTPS traffic into two different Node.js backends - one that only serves ALPN certificates for challenge responses, and the other for actual end-user traffic that serves certificates retrieved from the ACME provider. As far as I *(library author)* know, routing HTTPS traffic based on ALPN protocol can not be done purely using Node.js.
+
+The end result should look something like this:
+
+```text
+Nginx or HAProxy (0.0.0.0:443)
+    *inspect requests SSL ALPN protocol*
+        If ALPN == acme-tls/1
+            -> Node.js ALPN responder (127.0.0.1:4444)
+        Else
+            -> Node.js HTTPS server (127.0.0.1:4443)
+```
+
+Example proxy configuration:
+
+* [haproxy.cfg](haproxy.cfg) *(requires HAProxy >= v1.9.1)*
+* [nginx.conf](nginx.conf) *(requires [ngx_stream_ssl_preread_module](https://nginx.org/en/docs/stream/ngx_stream_ssl_preread_module.html))*
+
+Big thanks to [acme.sh](https://github.com/acmesh-official/acme.sh) and [dehydrated](https://github.com/dehydrated-io/dehydrated) for doing the legwork and providing Nginx and HAProxy config examples.
+
+## How it works
+
+When solving `tls-alpn-01` challenges, you prove ownership of a domain name by serving a specially crafted certificate over HTTPS. The ACME authority provides the client with a token that is placed into the certificates `id-pe-acmeIdentifier` extension along with a thumbprint of your account key.
+
+Once the order is finalized, the ACME authority will verify by sending HTTPS requests to your domain with the `acme-tls/1` ALPN protocol, indicating to the server that it should serve the challenge response certificate. If the `id-pe-acmeIdentifier` extension contains the correct payload, the challenge is valid.
+
+## Pros and cons
+
+* Challenge must be satisfied using port 443 (HTTPS)
+* Useful in instances where port 80 is unavailable
+* Can not be used to issue wildcard certificates
+* More complex than `http-01`, can not be solved purely using Node.js
+* If using multiple web servers, all of them need to respond with the correct certificate
