ubuntu20.04时区设置为上海

将系统时间设置为时区为上海,24小时制方便查看日志,cron保证集群时间同步。

apt install chrony -y  systemctl status chrony  systemctl enable --now chrony  find / -name Shanghai  ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime   echo LC_TIME=en_DK.UTF-8 >> /etc/default/locale  apt install ntpdate -y  ntpdate time1.aliyun.com  echo */5 * * * * ntpdate time1.aliyun.com &> /dev/null && hwclock -w >> /var/spool/cron/crontabs/root  reboot
