Thank you first!
My environment is a pdns master node, two pdns slave nodes, that is, three servers. Whether I deploy on two slave nodes or all nodes deploy recursor, master-slave synchronization fails!
From the node's configuration file:
# Number of seconds to store packets in PacketCache
# The number of seconds to store negative query results in QueryCache
# Number of seconds to store query results in QueryCache
# Accept the threads of the Packets (generally the same as the number of CPU cores)
# Number of threads per thread connected backend
# Database related configuration
# webserverrelated configuration
# webserver login username
# slave node configuration
# This is the number of seconds between the slave check area updates
# Insert the name in the SOA record if there is no setting in the backend
Recursor configuration file:
# Allow all clients to make DNS requests
# Specify the domain name that needs to be forwarded
# No domain name specified, default forwarding to 188.8.131.52
I don't know what my configuration is wrong? Still there, please help me.
I always see this error on the API monitoring page of the 8081.
