Linux NTP Server Setting

Hi,

Time setting is very important on Linux server for database and application. Because application and database are mostly getting time from server.

 

You can check date with following query

[root@MehmetSalih ~]# date
Sun Mar 10 20:59:09 +03 2019
[root@MehmetSalih ~]#

 

Date and time should are taken from Central NTP ( Network Time Protocol )  Server.

You can check NTP Server with following query.

[root@MehmetSalih ~]# service ntpd status
ntpd is stopped
[root@MehmetSalih ~]#

If NTP Daemon is not started then you should add NTP Server adress to the /etc/ntp.conf like following.

[root@MehmetSalih ~]# vi /etc/ntp.conf
server 192.168.63.63
server 192.168.63.34

 

 

NTP Server IP is added to the /etc/ntp.conf then we can start NTP daemon like following.

[root@MehmetSalih ~]# service ntpd start
Starting ntpd: [ OK ]
[root@MehmetSalih ~]#


[root@MehmetSalih ~]# service ntpd status
ntpd (pid 4040) is running...
[root@MehmetSalih ~]#

 

If you want to stop ntp, you can use following query.

[root@MehmetSalih ~]# service ntpd stop
Shutting down ntpd: [ OK ]
[root@MehmetSalih ~]#
[root@MehmetSalih ~]# service ntpd status
ntpd is stopped
[root@MehmetSalih ~]#

 

You can update date and time from NTP server manually like following.

[root@MehmetSalih ~]# ntpdate –u 192.168.63.63
[root@MehmetSalih ~]#
