I am living in Asia that's why i'm using this pool. Install Chrony and Configure The NTP server . # yum -y install chrony ( for rpm based ) # apt install chrony ( for debian based ) # vi /etc/chrony.conf ( for rpm based ) # vi /etc/chrony/chrony.conf ( for debian based ) #server 0.centos.pool.ntp.org iburst #server 1.centos.pool.ntp.org iburst #server 2.centos.pool.ntp.org iburst #server 3.centos.pool.ntp.org iburst server 0.asia.pool.ntp.org iburst server 1.asia.pool.ntp.org iburst server 2.asia.pool.ntp.org iburst server 3.asia.pool.ntp.org iburst add the network range you allow to receive requests allow 127.0.0.1 or allow your network cidr :x (save & quit) Reminder: We have disabled firewalld, So we will add the port 123/udp after the CWP installation using CSF firewall.  Start the services and e

This Tutorial describes how to disable the Network Manager service. The Network Manager service automates the network's settings and disrupts connections to the IP addresses that reside in the ipaliases module. We recommend that you disable the Network Manager service and enable the network.service service before you install EFA/Cpanel/CWP7/VestaCP. # systemctl stop NetworkManager # systemctl disable NetworkManager # nmcli device status # systemctl list-unit-files | grep NetworkManager # systemctl enable network.service # systemctl restart network.service Reboot The Machine # reboot I have two NIC in my VPS, So Add the below parameter in /etc/sysconfig/network-scripts/ifcfg-eXXX of interfaces that are managed by NetworkManager to make it unmanaged.
