在日常巡检中发现系统日志与系统时间不一致问题。
解决思路
查看时区是否异常
[root@46 phase2]# date -R
Mon, 09 Aug 2021 10:24:24 +0800
[root@46 phase2]# timedatectl
Local time: 一 2021-08-09 10:24:34 CST
Universal time: 一 2021-08-09 02:24:34 UTC
RTC time: 一 2021-08-09 02:24:34
Time zone: Asia/Shanghai (CST, +0800)
NTP enabled: yes
NTP synchronized: yes
RTC in local TZ: no
DST active: n/a如时区不为+0800则替换配置
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime系统日志时间不一致
查看/var/log/messages 日志内容发现时间与系统时间不一致
