In the process of filling... Later I will add an auto-deployment script

An example process of how to set up load balancing at the DNS server level

Will use Centos and Dnsmasq as DNS server

1. First you need to install dnsmasq

yum install dnsmasq bind-utils

-------- I don't remember if this is necessary ----------
Next, specify 127.0.0.1 as the DNS server

echo “nameserver 127.0.0.1” > /etc/resolv.conf

--------------------------!--------------------------------------

2.Next, copy the following files to /etc/ :

• dnsmasq.conf

• domains.conf

• servertest.sh

  In the dnsmasq.conf file you need to add your server IP: listen-address=YOUR_IP

  domains.conf - list of your domains, if there is more than one

  servertest.sh - here you need to specify the IP of your servers

  3. Add servertest.sh to Cron

  crontab -e

  */2 * * * * bash /etc/serverstest.sh > /dev/null 2>&1
