The newly installed cluster (CentOS 6.6) runs the program and finds that the time is wrong. It is necessary to reset the time and synchronize the network.
Execute the following command in the terminal command:
1). vi /etc/sysconfig/clock #Edit the time configuration file
ZONE="Asia/Shanghai"
UTC=false #Set to false, the hardware clock is not consistent with the UTC time
ARC=false
2). cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime #linux time zone is set to Shanghai time zone
3). ntpdate cn.pool.ntp.org #align the time
4). /sbin/hwclock --systohc #Set the hardware time to be consistent with the system time and calibrate
After the above steps, our CentOS linux system time and computer hardware time are finally cst time, and both are in Shanghai time zone.
