first，need a template file like this:

server {
        listen       80;
        server_name  domain_name;
        access_log  /var/log/nginx/xxx.log;
        error_log   /var/log/nginx/xxx.error.log;
        error_page 497 https://$host$request_uri;
        rewrite ^(.*)$ https://${server_name}$1 permanent;
}
server {
        listen 443 ssl http2;
        server_name domain_name;
        access_log  /var/log/nginx/xxx.log;
        error_log   /var/log/nginx/xxx.error.log;
        root /data/www/domain_name;

    sub_filter_once off;
    sub_filter '<head>' '<head><script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygo
ogle.js?client=ca-pub-88888888" crossorigin="anonymous"></script>';

        index index.html index.htm;
        ssl_certificate /etc/nginx/key/moneyslow.com.fullchain.cer;
        ssl_certificate_key /etc/nginx/key/moneyslow.com.key;
}

all the domain in file : domain_moneyslow.txt

next , a shell for create config file from domain_moneyslow.txt and template :

#!/bin/bash
while read -r line; do
  echo $line;
sed "s/domain_name/$line/g;" template > xxx/$line.conf
done < domain_moneyslow.txt
