Since the company's games need to be launched in Vietnam and South Korea, the time in Vietnam is one hour slower than ours, and the time in South Korea is one hour faster than ours, therefore, when configuring the system environment on the server, you need to set the time point for the Vietnamese server to synchronize with the Vietnamese server. the time point for the Korean server to synchronize with the Korean server is as follows:

 

1. set the time synchronization for Vietnamese servers:

Cat>/var/spool/cron/root < */30 */usr/sbin/ntpdate nt1_cs. mu. OZ. AU>/dev/null 2> & 1
EOF

Service crond restart

 

/Bin/rm-f/etc/localtime

Cp/usr/share/zoneinfo/Asia/Saigon/etc/localtime

Cat>/etc/sysconfig/clock < ZONE = "Asia/Saigon"
UTC = false
ARC = false
EOF

Cat>/etc/ntp. conf <EOF
Server cn.pool.ntp.org prefer
Server 210.72.145.44
Server cn.pool.ntp.org
Server ntp1.cs. mu. OZ. AU
Server ntw.cs. mu. OZ. AU
Server ntp.alaska.edu
Driftfile/var/lib/ntp. drift
EOF

 

Ntpdate cn.pool.ntp.org
/Sbin/hwclock-w

Cat>/var/spool/cron/root < */30 */usr/sbin/ntpdate nt1_cs. mu. OZ. AU>/dev/null 2> & 1
EOF

Service crond restart
