金融网站怎么做的外贸建站推广公司

1、环境介绍

操作系统：龙蜥OS 8.9
中间件：nginx
证书：Let’s Encrypt
https://letsencrypt.org/zh-cn/
证书部署工具：acme.sh
域名托管厂商：阿里云

2、安装acme.sh

curl https://get.acme.sh | sh
source ~/.bashrc

3、创建阿里云RAM用户

登录阿里云 RAM 控制台，创建用户 & AccessKey
访问：https://ram.console.aliyun.com/users
创建 AccessKey，记住 ID 和 Secret

echo 'export Ali_Key="你的AccessKeyId"' >> ~/.bashrc
echo 'export Ali_Secret="你的AccessKeySecret"' >> ~/.bashrc
source ~/.bashrc

这里需要授权AliyunDNSFullAccess

4、申请证书

acme.sh --issue --dns dns_ali -d gubeisz.net -d '*.gubeisz.net' --server letsencrypt

阿里云这里也会生成txt记录

计划任务里会自动更新证书

5、使用ansible 自动分发证书

ansible 服务器免登录

ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.99.99.120

代理到证书服务器免认证

ssh-keygen -t rsa -b 4096 -C "proxy-to-cert" -N "" -f ~/.ssh/id_rsa
ssh-copy-id root@10.99.50.11

playbook

6、验证证书
