使用cat和重定向写配置文件

cat << EOF > /etc/nginx/conf.d/www.dfxj.top.conf
server{
    server_name  dfxj.top www.dfxj.top;
    location / {
        proxy_set_header HOST \$host;
        proxy_set_header X-Forwarded-Proto \$scheme;
        proxy_set_header X-Real-IP \$remote_addr;
        proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:8099/;
        client_max_body_size 200M;

    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/www.dfxj.top/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/www.dfxj.top/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

server{
    if (\$host = www.dfxj.top) {
        return 301 https://\$host\$request_uri;
    } # managed by Certbot


    listen      80;
    server_name  dfxj.top www.dfxj.top;
    return 404; # managed by Certbot


}

EOF

注意$需要转义，不然脚本会以shell的变量处理$后面的字符。
