NTP与系统时间设置

# 一、安装基础服务

sudo apt install systemd-timesyncd

# 如果因为系统时间问题导致apt源不可用

手动设置时间

sudo date -s "2025-06-26 00:26:00" # 设置为当前时间

# 二、修改NTP服务器地址

sudo vim /etc/systemd/timesyncd.conf

添加NTP服务器

[Time]
NTP=ntp.aliyun.com ntp1.aliyun.com ntp2.aliyun.com
#FallbackNTP=ntp.ubuntu.com

重启服务

sudo systemctl restart systemd-timesyncd

检查状态

timedatectl status

# 理想输出
tspi@localhost:~$ timedatectl status
