Operating system ntp service settings:
# check the current system time zone, if it is not Shanghai, modify it to Shanghai
Timedatectl | grep "Time zone"
Timedatectl set-timezone Asia/Shanghai
Cp / usr/share/zoneinfo/Asia/Shanghai / etc/localtime
Install the ntp service
Yum install ntpdate-y
# write timing task synchronization time
Crontab-e
0-59 take 10 / usr/sbin/ntpdate ntp1.aliyun.com | logger-t NTP
# Test whether the synchronization time can be successful
/ usr/sbin/ntpdate ntp1.aliyun.com
Service deployment, dependent deployment:
Yum install gcc wget-y
