004-零失败快速搞定通配符SSL证书

$ curl https://get.acme.sh | sh
# 或者
$ wget -O -  https://get.acme.sh | sh
# 或者
$ git clone https://github.com/Neilpang/acme.sh.git
$ ./acme.sh/acme.sh --install

$ export DP_Id="你的ID"
$ export DP_Key="你的Token"
$ acme.sh --issue --dns dns_dp -d example.com -d *.example.com
# 如果 使用了DNS别名，还需要增加 --challenge-alias 别名域名 参数
# 为了防止dns不生效，脚本会暂停2分钟，并倒计时(Sleep 120 seconds for the txt records to take effect),等待即可
# 如果成功会出现 Cert success. 字样
# 不建议直接用~/.acme.sh 下的证书，参考 https://github.com/Neilpang/acme.sh/wiki/说明#3-copy安装-证书
# 需要使用 --installcert 复制到指定目录
