In this issue, Xiaobian will bring you about how to achieve time synchronization in Linux. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

Method 1:

Synchronizing with a known time server

The code is as follows:

ntpdate time.nist.gov

Where time.nist.gov is a time server.

Delete local time and set time zone to Shanghai

The code is as follows:

rm -rf /etc/localtime

ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

Method 2:

Linux automatic synchronization time

vi /etc/crontab

Add:

The code is as follows:

00 0 1 * * root rdate -s time.nist.gov

Configuration Time Server Configuration (192.168.10.1)

The code is as follows:

1）、# rpm -ivh ntp-4.1.2-4.EL3.1.i386.rpm

2）、# vi /etc/ntp.conf

One line of comment:

restrict default ignore

Insert a line:

The code is as follows:

restrict 192.168.10.0 mask 255.255.255.0 notrust nomodify notrap

3）、# vi /etc/ntp/step-tickers

Insert a line:

pool.ntp.org

This way, every time ntpd starts, it will automatically connect to the international standard time server;

4）、# service ntpd start

5）、# netstat -an |grep 123

Make sure the port is open in udp mode

Time Client Configuration (192.168.10.2)

1）、# ntpdate 192.168.10.2

Should show synchronization success

2）、# crond -e

join

The code is as follows:

0-59/10 * * * * /usr/sbin/ntpdate 192.168.10.1

Time synchronization every 10 minutes
