参考 github 官方操作 ，acme操作说明
说下我的操作
- 安装 acme.sh
curl https://get.acme.sh | sh
source ~/.bashrc
2.注册
acme.sh --register-account -m 123@qq.com
如果你在配置 acme.sh 时选择了其他 CA（如 Let’s Encrypt），你可以通过以下命令切换 CA：
下面命令二选一，我的服务器不支持第一种，所以直接用第二条命令执行，切换CA
~/. --set-default-ca letsencrypt
acme.sh --set-default-ca --server letsencrypt
3.使用 HTTP 验证
这里也给两条命令，我用第一个执行下来有问题，所以我直接用第二个命令
acme.sh --issue -d boss-dream.com -d www.boss.com --webroot /home/wwwroot/www.boss.com
acme.sh --issue -d boss-dream.com -d www.boss.com --webroot /home/wwwroot/www.boss.com --debug
4、执行完第三步，可能会报错，以下是错误的截图，错误的最后一部分：

遇到这个错误后，需要在nginx配置里面加一个路由验签操作
location /.well-known/acme-challenge/ {
root /home/wwwroot/www.boss.com;
}
# 注意需要放在location / 之前
location / {
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ =404;
}
然后重新执行这个命令
acme.sh --issue -d boss-dream.com -d www.boss.com --webroot /home/wwwroot/www.boss.com --debug
看到success 就ok了
续签命令
acme.sh --renew -d www.test.com --force
