root@primary_gateway:~$ sh ezlogin_7.36.0_php81.bin -- -dbsuser root -dbspass <enter-_(root)db_password> -auto -force -ACCEPT_SETTINGS -I_ACCEPT_EULA -update

4. Run the following command on your master node after upgrade

root@primary_gateway:~$ php /usr/local/ezlogin/grant_host.php <new_ip_address of secondary node/slave>

root@secondary:~$ sh ezlogin_7.36.0_php81.bin -- -secondary <ip_adress of the slave node> -othernode <ip_address of master node> -update -auto -force -ACCEPT_SETTINGS -I_ACCEPT_EULA
