Rexerver

===========

A DNS MAnager Built from scratch in Golang using the microservices design pattern, it consists of 6 services

• DNS Resolver (with an optional forwarder fallback)
• RESTful API (to make it easy to manage the entries)
• Hosts File(s) compatible service, so you can provide hosts file to it and it will resolve host names from it.
• Caching layer, to low the I/O usage.
• Dashboard using laravel (a PHP framework)
• Nginx for service the dashboard.

$ How to change the dns port ?

By default any dns service uses the udp 53 port, but you can change it from the shell script /root/rexerver.sh by changing the value of --listen-dns to your own port.

$ How to change the dashboard port ?

Go to /etc/nginx/sites-enabled/rexerver, change the value of listen from 8080 to anything else, THEN execute the following command service nginx restart.

$ How to change the port of the RESTful API ?

Go to /root/rexerver.sh, change the value of listen-api to anything else THEN YOU MUST change the same configurations in /var/rexerver/laravel.env, change API_BASE_URL to something else.

$ Can I change the cache TTL ?

Cache is used to make it high performance, so just change the value of cache in the /root/rexerver.sh to something else.

$ How to restart the service/clean the cache ?

pm2 restart rexerver
