包括单域名和泛域名通配符。
无
主要步骤:(引自官网)
1.安装 acme.sh
2.生成证书
3.copy 证书到 nginx/apache 或者其他服务
4.更新证书
5.更新 acme.sh
6.出错怎么办, 如何调试
yum update
yum install curl -y
yum install cron -y
安装很简单, 一个命令:
curl https://get.acme.sh | sh
或者(推荐)
yum update wget
wget -O - https://get.acme.sh | sh
如果报错curl: (35) SSL connect error
,移步:https://janeyork.blog.csdn.net/article/details/82700159
如果报错curl: (7) couldn't connect to host
出站端口dport 443、80添加了或者防火墙关闭。

COMMIT
普通用户和 root 用户都可以安装使用. 安装过程进行了以下几步:
~/.acme.sh/ (这个是自动执行的安装目录)
并创建 一个 bash 的 alias, 方便你的使用: alias acme.sh=~/.acme.sh/acme.sh
这个是自动操作,如果没有请手动。
出现install success即为成功。
自动为你创建了cronjob。
关闭shell重新打开。或者让命令立即生效source ~/.bashrc
验证方式一:DNS手动验证。(个人推荐)
https://github.com/acmesh-official/acme.sh
acme.sh --issue -d example.com -d *.example.com --dns \
--yes-I-know-dns-manual-mode-enough-go-ahead-please
验证TXT解析是否生效
dig -t txt _acme-challenge.xxoo.com @8.8.8.8
添加解析生效后,重新生成证书。
acme.sh --renew -d xxoo.com -d *.xxoo.com \
--yes-I-know-dns-manual-mode-enough-go-ahead-please
注意:
export DINGTALK_WEBHOOK='https://oapi.dingtalk.com/robot/send?access_token=5241080f1e14f0d8af2fa6cef175934f0d9d636'
export DINGTALK_KEYWORD=acme
acme.sh --set-notify --notify-hook dingtalk \
--notify-level 2 \
--notify-mode 0
$ export Ali_Key="woshipogaizai"
$ export Ali_Secret="nishipogaizaima"
这两个配置将永久保存在文件~/.acme.sh/account.conf中
# 申请
acme.sh --issue --dns dns_ali -d xxoo.com -d *.xxoo.com
# DP
# acme.sh --issue --dns dns_dp -d mydomain.com -d *.mydomain.com
证书申请成功后,保存在~/.acme.sh/www.example.com目录下
查看证书
删除证书
方式2、HTTP文件验证:
$ acme.sh --issue -d congm.in -d *.congm.in -w /home/webroot
注意
:对于通配符证书需要加-d 域名 -d *.域名
两个参数-w
即webroot,为该域名
通过http所访问到的本地目录上面这段过程将会在/home/webroot
创建一个.well-known
的文件夹,同时 Let’s Encrypt 将会通过你要注册的域名去访问那个文件来确定权限,它可能会去访问 http://xxoo.in/.well-known/ 这个路径,验证成功会自动清理。
acme.sh --issue -d nogit.top -d *.nogit.top --dns \
--yes-I-know-dns-manual-mode-enough-go-ahead-please
验证TXT解析是否生效
dig -t txt _acme-challenge.nogit.top @8.8.8.8
添加解析生效后,重新生成证书。中间可能等待一小会儿
acme.sh --renew -d nogit.top -d *.nogit.top \
--yes-I-know-dns-manual-mode-enough-go-ahead-please
执行过程截图:
生成结果:

导出Tomcat pfx格式证书:
acme.sh --toPkcs -d nogit.top --password 1234
导出Nginx:
key.pem和pri.key,可以直接更改后缀pem或者key
fullchain同理,两者内容一样,可以直接更改后缀
mkdir -p /home/mycert
acme.sh --installcert -d nogit.top \
--key-file /home/mycert/privateKey.pem \
--fullchain-file /home/mycert/fullchain.pem \
--ca-file /home/mycert/ca.cer \
--cert-file /home/mycert/nogit.top.cer
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.pem -in nogit.top.cer -certfile ca.cer -password "pass:Rookie123"
或者:(两个一样的,只是我把文件名重命名而已)
openssl pkcs12 -export -out certificate.pfx -inkey nogit.top.key -in nogit.top.cer -certfile ca.cer -password "pass:Rookie123"

然后配置到Tomcat里
