Thêm nhiều site vào Cloudflare bằng automation Add multiple sites via automation

To add multiple sites to Cloudflare at once and more efficiently, you can do so via the Cloudflare API.

Adding multiple sites can be useful when you:

• Have multiple domains mapping back to a single, canonical domain (common for domains in different countries - such as .com.au, .co.uk \- that you want protected by Cloudflare).
• Are a partner ↗, agency, or IT consultancy, and manage multiple domains on behalf of your customers.
• Are moving an existing set of sites over to Cloudflare.

Using the API will allow you to add multiple sites quickly and efficiently, especially if you are already familiar with how to change your nameservers or add a DNS record.

This tutorial assumes domains will be added using a primary DNS setup (full).

To add multiple sites to Cloudflare via automation, you need:

• An existing Cloudflare account.
• Command line with curl
• A Cloudflare API token with one of the following permissions:

Zone-level Administrator Zone-level Zone: Edit and DNS: Edit * Account-level Domain Administrator

• To have disabled DNSSEC for each domain at your registrar (where you bought your domain name).

1. Create a list of domains you want to add, each on a separate line (newline separated), stored in a file such as domains.txt.
2. Create a bash script add-multiple-zones.sh and add the following. Add domains.txt to the same directory or update its path accordingly.

Terminal window

for domain in $(cat domains.txt); do

    printf "Adding ${domain}:\n"


    curl https://api.cloudflare.com/client/v4/zones \

    --header "Authorization: Bearer <API_TOKEN>" \

    --header "Content-Type: application/json" \

    --data '{

      "account": {

        "id":"<ACCOUNT_ID>"

      },

      "name": "'"$domain"'",

      "type": "full"

    }'


    printf "\n\n"

  done

1. Open the command line and run:

Terminal window

bash add-multiple-zones.sh

Warning

There are limitations on the number of domains you can add at a time. Refer to limitations for details.

After adding a domain, it will be in a Pending Nameserver Update state.

For each domain to become active on Cloudflare, it must be activated in either Full setup or Partial setup. The following script will output a list containing the nameservers associated with each domain.

You can find your zones nameservers in the following locations:

• Create Zone
• Zone Details

1. Modify your script add-multiple-zones.sh to print a CSV with data from the Create Zone JSON response.

JavaScript

for domain in $(cat domains.txt); do

    printf "Adding ${domain}:\n"


    add_output=`curl https://api.cloudflare.com/client/v4/zones \

      --header "Authorization: Bearer <API_TOKEN>" \

      --header "Content-Type: application/json" \

      --data '{

        "account": {

          "id": "<ACCOUNT_ID>"

        },

        "name": "'"$domain"'",

        "type": "full"

      }'`


    # Create csv of nameservers

    echo $add_output | jq -r '[.result.name,.result.id,.result.name_servers[]] | @csv' >> /tmp/domain_nameservers.csv


    domain_id=`echo $add_output | jq -r .result.id`


    printf "\n\n"

    printf "DNS quick scanning ${domain}:\n"


    scan_output=`curl --request POST https://api.cloudflare.com/client/v4/zones/$domain_id/dns_records/scan \

      --header "X-Auth-Email: <EMAIL>" \

      --header "X-Auth-Key: <API_KEY>"`


    echo $scan_output | jq .


  done


  printf "name_servers are saved in /tmp/domain_nameservers"

  cat /tmp/domain_nameservers.csv

| ID | ZONE | NAME SERVERS | | ---------- | ----------- | --------------------------------------------- | | <ZONE\_ID> | example.com | arya.ns.cloudflare.com, tim.ns.cloudflare.com |

1. Use the values in the NAME SERVERS column to update the nameservers at the registrar of each domain.

There are limitations on the number of domains you can add at a time - specifically, you can only sign up a maximum of 25 domains every 10 minutes.

In addition, if you have over 50 domains and, of those domains, more are pending than active, you will be blocked from adding more. We recommend waiting until your pending sites have been activated before adding more.

If any errors were returned in this process, the domain may not be registered (or only just registered), be a subdomain, or be otherwise invalid. For more details, refer to Cannot add domain.
