    Instalar y configurar NTP en Linux CentOS para sincronizar el reloj del sistema



    How do I install and configure NTP under CentOS Linux version 5.x or 6.x server to synchronize the system clock?

    You can easily install NTP (Network Time Protocol, a means of transmitting time signals over a computer network) using the yum command under Red Hat or CentOS/Fedora Linux server or workstation based systems. You need to install the following packages:

    1. ntp : ntpd server which continuously adjusts system time and utilities used to query and configure the ntpd daemon.
    2. ntpdate : Utility to set the date and time via NTP.
    3. ntp-doc : NTP documentation

    Procedure: Setup NTPD on CentOS Linux

    Open the terminal or login over the ssh session. You must login as as the root user. Type the following yum command to install ntp
    # yum install ntp ntpdate ntp-doc

    Turn on service, enter:
    # chkconfig ntpd on

    Synchronize the system clock with 0.pool.ntp.org server (use this command only once or as required):
    # ntpdate pool.ntp.org

    Start the NTP server. The following will continuously adjusts system time from upstream NTP server. No need to run ntpdate:
    # /etc/init.d/ntpd start

    o

    # service ntpd start

    Configure ntpd (optional)

    Edit /etc/ntp.conf, enter:
    # vi /etc/ntp.conf

    Set public servers from the pool.ntp.org project:
    server 0.rhel.pool.ntp.org
    server 1.rhel.pool.ntp.org
    server 2.rhel.pool.ntp.org
    

    See this tutorial on how to configure NTPD for LAN based client on RHEL / CentOS Linux for more information.
