Requirements: I have 100+ first-level domain names that need SSL certificates
-
Install OpenResty. The official website recommends using 15.8.1 or above:
https://github.com/auto-ssl/lua-resty-auto-ssl -
Install luarocks
wget http://luarocks.org/releases/luarocks-2.0.13.tar.gz //下载
tar -xzvf luarocks-2.0.13.tar.gz //解压
cd luarocks-2.0.13/
//这里需要注意prefix 路径跟自己的openresty安装路径是否匹配
./configure --prefix=/usr/local/openresty/luajit \
--with-lua=/usr/local/openresty/luajit/ \
--lua-suffix=jit \
--with-lua-include=/usr/local/openresty/luajit/include/luajit-2.1
make
sudo make install
- Install components
cd /usr/local/openresty/luajit
./luarocks install lua-resty-auto-ssl
mkdir /usr/local/openresty/ssl
mkdir /usr/local/openresty/ssl/resty-auto-ssl
chown -R nobody.nobody /usr/local/openresty/ssl/resty-auto-ssl
chmod -R 777 /usr/local/openresty/ssl
- Make a self-signed certificate
cd /usr/local/openresty/ssl/resty-auto-ssl
openssl req -new -newkey rsa:2048 -days 3650 -nodes -x509 \
-subj '/CN=sni-support-required-for-valid-ssl' \
-keyout /usr/local/openresty/ssl/resty-auto-ssl-fallback.key \
-out /usr/local/openresty/ssl/resty-auto-ssl-fallback.crt
- Configure nginx.conf

-- 定义一个函数用于决定哪个域名自动处理和注册新证书。默认是不允许任务域名。所以该配置也是必须项。
-- 替换 example.com 为自己的域名，直接返回 true 表示所有请求进来的域名都颁发证书
auto_ssl:set("allow_domain", function(domain)
-- return ngx.re.match(domain, "(luozixu2.com|luozixu.net)$", "ijo")

-- example.com$ 可以为所有 example.com 子域名颁发证书

nginx
dns binds the domain name to curl https://domain name on nginx
Check whether the certificate path generated the certificate:
The problem can also be seen in the nginx error log:
