Script for automatically get "Let's Encrypt" wildcard domain certificate at CentOS, using delegated NS server at NIC.RU

• Domain for which we want get wildcard letsencrypt certificate (Domain's name servers (NS) should be delegated to DNS server at NIC.RU)
• At NIC.RU DNS service there must be A record containing domain, for which we need to get certificate
• CentOS 7
• Python >= 3.6
• certbot >= 1.11.0

• At https://www.nic.ru

  • Login to your account
  • go to "Услуги/DNS-хостинг" - Управление DNS-зонами - "Добавить домен"
  • add your domain "example.com" to list
  • delegate NS servers of domain "example.com" to nic.ru
  • add any A-record for your domain (for example: "@ A 1.1.1.1")
  • go to "Услуги/DNS-хостинг". Column "Услуга" contains alphabetical name: <SERVICE_ID>. Remember it
  • go to: https://www.nic.ru/manager/oauth.cgi?step=oauth.app_register
  • create APP named "letsencrypt_nicru"
  • get and remember: APP-LOGIN, APP-PASSWORD

• At CentOS 7

  yum install -y epel-release
  

  yum install -y git certbot python36
  

  pip3.6 install requests nic-api
  

  cd /opt/
  

  git clone https://github.com/clesssalvein/letsencrypt-nicru.git
  

• Edit variables in "start.sh"
• Run ./start.sh

• "start.sh" contains variables and starts certbot with auth script "nicru-auth.sh" and postscript "nicru-cleanup.sh"
• "nicru-auth.sh" starts "nicru-add-entry.py", which put to NIC.RU dns server TXT entry with certbot validation string
• certbot validates text string
• after successfull validation certbot generates a certificate and downloads it to the local directory /etc/letsencrypt
• "nicru-cleanup.sh" starts "nicru-del-entry.py", which delete TXT entry with certbot validation string at NIC.RU dns server
