In the company's operations, DNS is still important, not only the name resolution requires DNS, some important services, such as load balancing, HTTP virtual host will also use it. I had previously developed a BIND DNS management system with Perl, but it had to run on the same server as bind DNS and did not support cluster operations. To accommodate Docker and distributed deployment, I have re-developed a set of Bind DNS Web management systems with Python Django.1. System Features: Supports

Therefore, I decided to adopt the default Bind mode. 2. function implementation: Without using the dlz database mode, the system design and development are complex. I use the following methods to implement related functions: View Management: File Operations + rndc Domain Management: File O

For details about how to configure DNS in linux, see Linux Enterprise Application-Linux server application. 1. Note that. the conf configuration file contains "/var/named". You must grant all the file permissions in "/var/named" to named. The command is as follows: "# chown named. named/var/named /*". 2. IN "/var/log/messages", we found a prompt similar to "IN: has no NS records" to check whether the zone file is incorrectly edited, for example,/var/named/peng.com. the zone configuration is a
