wget https://raw.githubusercontent.com/Quartercn/CloudFlare_DNS_Record/Setter/CloudFlare_DDNS_Setter.sh

you should write your configuration down to config.conf :

# do not write interpretations into config file

# the email address of your cloudflare account
email=

# the zone id of your cloudflare account
zone_id=

# the api key of your cloudflare account
api_key=

# the domain you want to set
domain=

# ttl of record (seconds)
# min value:120
# max value:2147483647
ttl=

# the id of domain record you want to modify
# you can't see it before ran this script
# this id can be added automatically via "get domain record_id" selection in the script
record_id=

#"true" or "false",if local host is AWS' lightsail and you need replace ip automatically, please turn "true".
lightsail_switich=false  

#Created static ip's name of lightsail. Input anything you prefer.
lightsail_ipname=

#The name of the instance you already hold.It's like "CentOS-1GB-Tokyo-1"
lightsail_instance=

take a example, you should write like this:

email=example@gmail.com
zone_id=3456dfdhfi465ff4ae263ef35esd060f
api_key=84058228se28e28898b6ds3ej78yuf2136654

domain=example.example.net
ttl=120

lightsail_switich=true  
lightsail_ipname=ip-of-tokyo
lightsail_instance=CentOS-1GB-Tokyo-1

write those config down:

  • email
  • zone_id
  • api_key
  • domain
  • ttl
  • lightsail_switich (true or not）
  • lightsail_ipname (if turn on)
  • lightsail_instance (if turn on)

step 2

if this is the first time the script is run

bash CloudFlare_DDNS_Setter.sh install

2.create new domain record

bash CloudFlare_DDNS_Setter.sh --ddns

for above, the parameter --ddns is to update your dns A record to refresh your ddns. Freely let it automatically via such as crontab. this script have already added a record that is */3 * * * * bash CloudFlare_DDNS_Setter.sh --ddns to /var/spool/cron/root,and you can use crontab -e to modify it.
