PowerDNS Configuration露
You need to configure PowerDNS to use the MySQL backend. First enable the MySQL backend: launch = gmysql Configure the MySQL database settings: gmysql-host= gmysql-port= gmysql-dbname= gmysql-user= gmysql-password= gmysql-dnssec=yes #gmysql-socket=Note PowerDNS can connect via socket or host/port. Configure the options for designate-central - specifically “connection” to point to your MySQL database [backend:powerdns] connection = mysql+pymysql://:@:/ Setup the database schema. $ designate-manage powerdns init $ designate-manage powerdns sync Restart PowerDNS and it should be ready to serve queries using the MySQL database as the backing store. PowerDNS deployment as hidden Master露One deployment scenario can be that the PowerDNS backend will be used as a “hidden” Master DNS for other DNS servers to consume via AXFR. Say you have 10.0.0.1 and 10.0.0.2 as slaves then configure the backend as follows in addition to other options [backend:powernds] domain_type = MASTER also_notify = 10.0.0.1,10.0.0.2Note This should mostly be used in connection with another backend acting as slave. |
