Two ways to share Linux under time synchronization

Method 1:

Sync 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 the 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 sync time

Vi/etc/crontab

Add a sentence:

The code is as follows:

0 1 * * Root rdate-s time.nist.gov

Configure 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

Comment Line:

Restrict default Ignore

Join a line:

The code is as follows:

Restrict 192.168.10.0 mask 255.255.255.0 notrust nomodify

3), # Vi/etc/ntp/step-tickers

Join a line:

pool.ntp.org

This will automatically connect to the international Standard Time server each time the ntpd is started;

4), # service NTPD start

5), # Netstat-an |grep 123

Make sure that the port is open in UDP

Time Client Configuration (192.168.10.2)

1), # ntpdate 192.168.10.2

Should show sync success

2), # CROND-E

Join

The code is as follows:

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

Sync time every 10 minutes
