![]() ![]() ![]() On the server, run the following command to display information about NTP clients assessing the NTP server. Now run the following command to show the current time sources ( NTP server) that chronyd is accessing, which should be your NTP server address. Then restart the chronyd service configurations for the recent changes to take effect. Save the changes in the file and close it. So comment out the default NTP servers specified as the value of the server directive, and set your RHEL 8 server’s address instead. You can specify the servers using the server or pool directive. To configure a system as an NTP client, it needs to know which NTP servers it should ask for the current time. Open the /etc/nf configuration file with a text-base editor. Next, you need to configure the system as a direct client of the NTP server. Once installed, you can start, enable and verify the chronyd service status using the following systemctl commands. Start by installing the chrony package using the following yum command. This section shows how to configure chrony as a direct NTP client in our CentOS 7 server. How to Configure NTP Client Using Chrony in RHEL 8 # firewall-cmd -permanent -add-service=ntp ![]() Next, open access to the NTP service in firewalld configuration to allows for incoming NTP requests from clients. Then restart the chronyd service configuration to apply the recent changes. Then look for the allow configuration directive and uncomment it and set its value to the network or subnet address from which the clients are allowed to connect. Open the /etc/nf configuration file using any of your favorite text-based editor. In this section, we will show how to set up your RHEL 8 server a master NTP time server. Start Chonyd in RHEL 8 How to Configure NTP Server Using Chrony in RHEL 8 Now start the chronyd service, enable it to auto start at system boot and verify the running status using the following systemctl commands. The chrony suite consists of chronyd, and chronyc, a command line utility which is used to change various operating parameters and to monitor its performance whilst it is running. This command will install a dependency called timedatex. To install the chrony suite, use the following DNF package manager as follows. In this article, we will show you how to install and configure the NTP server and client using chrony package in RHEL 8 Linux distribution.

In RHEL Linux 8, the ntp package is no longer supported and it is implemented by the chronyd (a daemon that runs in user-space) which is provided in the chrony package.Ĭhrony works both as an NTP server and as an NTP client, which is used to synchronize the system clock with NTP servers, and can be used to synchronize the system clock with a reference clock (e.g a GPS receiver). It can also be used as a time source/server for client systems. It commonly synchronizes a computer to Internet time servers or other sources, such as a radio or satellite receiver or telephone modem service. NTP is an old, widely known and cross-platform protocol designed to synchronize the clocks of computers over a network. Accurate timekeeping can be achieved using the Network Time Protocol ( NTP) protocol. Having an accurate system time on a Linux server is very important because of several system components such as Cron and Anacron, backup scripts and much more work based on time. ![]()
