github:https://github.com/acmesh-official/acme.sh
概述
一个纯粹用Shell（Unix shell）语言编写的ACME协议客户端。
完整的ACME协议实施。 支持ACME v1和ACME v2 支持ACME v2通配符证书
简单，功能强大且易于使用。你只需要3分钟就可以学习它。
Let's Encrypt免费证书客户端最简单的shell脚本。
纯粹用Shell编写，不依赖于python或官方的Let's Encrypt客户端。
只需一个脚本即可自动颁发，续订和安装证书。 不需要root/sudoer访问权限。
支持在Docker内使用，支持IPv6
安装 acme.sh
curl https://get.acme.sh | sh
并创建 一个 bash 的 alias, 方便你的使用: alias acme.sh=~/.acme.sh/acme.sh
生成证书
acme.sh 实现了 acme 协议支持的所有验证协议. 一般有两种方式验证: http 和 dns 验证. \
http方式
http 方式需要在你的网站根目录下放置一个文件, 来验证你的域名所有权,完成验证. 然后就可以生成证书了.
acme.sh --issue -d kubesre.com -d www.kubesre.com --webroot /application/nginx/html/
只需要指定域名, 并指定域名所在的网站根目录. acme.sh 会全自动的生成验证文件, 并放到网站的根目录, 然后自动完成验证. 最后会聪明的删除验证文件. 整个过程没有任何副作用.
如果你用的 web服务器, acme.sh 还可以智能的从 apache的配置中自动完成验证, 你不需要指定网站根目录:
acme.sh --issue -d kubesre.com --apache
acme.sh --issue -d kubesre.com --nginx
dns方式
手动 dns 方式, 手动在域名上添加一条 txt 解析记录, 验证域名所有权
这种方式的好处是, 你不需要任何服务器, 不需要任何公网 ip, 只需要 dns 的解析记录即可完成验证. 坏处是，如果不同时配置 Automatic DNS API，使用这种方式 acme.sh 将无法自动更新证书，每次都需要手动再次重新解析验证域名所有权。
acme.sh --issue --dns -d kubesre.com \
--yes-I-know-dns-manual-mode-enough-go-ahead-please
然后, acme.sh 会生成相应的解析记录显示出来, 你只需要在你的域名管理面板中添加这条 txt 记录即可.
等待解析完成之后, 重新生成证书:
acme.sh --renew -d kubesre.com --yes-I-know-dns-manual-mode-enough-go-ahead-please

注意第二次这里用的是 --renew
dns 方式的真正强大之处在于可以使用域名解析商提供的 api 自动添加 txt 记录完成验证.
acme.sh 目前支持 cloudflare, dnspod, cloudxns, godaddy 以及 ovh 等数十种解析商的自动集成.
以 dnspod 为例, 你需要先登录到 dnspod 账号, 生成你的 api id 和 api key, 都是免费的. 然后:
export DP_Id="kube123"
export DP_Key="sADDsdasdgdsf"
acme.sh --issue --dns dns_dp -d kubesre.com -d www.kubesre.com
证书就会自动生成了. 这里给出的 api id 和 api key 会被自动记录下来, 将来你在使用 dnspod api 的时候, 就不需要再次指定了. 直接生成就好了:
acme.sh --issue -d kubesre.com --dns dns_dp
更详细的 api 用法: https://github.com/Neilpang/acme.sh/blob/master/dnsapi/README.md
更新证书
目前证书申请后有效期为60天
目前由于 acme 协议和 letsencrypt CA 都在频繁的更新, 因此 acme.sh 也经常更新以保持同步.
# 升级 acme.sh 到最新版
acme.sh --upgrade
# 如果你不想手动升级, 可以开启自动升级:
acme.sh --upgrade --auto-upgrade
#之后, acme.sh 就会自动保持更新了.
# 你也可以随时关闭自动更新:
acme.sh --upgrade --auto-upgrade 0
修改 CA
默认 CA 将使用ZeroSSL，由于特殊需求需要更改CA，请通过下面的方式进行修改。
可以通过提供--server参数自由使用任何受支持的 CA ：
acme.sh --issue -d kubesre.com --dns dns_cf --server letsencrypt
也可以通过 --set-default-ca 设置的默认 ca：
acme.sh --set-default-ca --server letsencrypt
基于CSR签发证书
通过openssl生成csr
openssl genrsa -out kubesre.com/kubesre.com.key 4096
openssl req -new -key kubesre.com/kubesre.com.key -out kubesre.com/kubesre.com.csr -subj "/C=CN/L=Shanghai/O=kubesre/OU=shanghai/CN=kubesre.com"
