- 檢視/usr/lib/systemd/system和/etc/systemd/system/multi-user.target.wants/已經設定了軟連結，說明設定了systemd開機啟動。
問題結論
|
Bash
OCP 納管主機時，已經將 set clock
source 會寫入到/etc/systemd/system中，但在自動修復時，會重新載入到/etc/systemd/system中，如果自動修復檢查時已經有這個檔案則報錯檔案已存在

從以上來看OCP 納管主機時，已經將 set
clock source 會寫入到/etc/systemd/system中，但在自動修復時，會重新載入到/etc/systemd/system中，如果自動修復檢查時已經有這個檔案則報錯檔案已存在
[root@localhost multi-user.target.wants]# systemctl list-unit-files | egrep
set_clocksource.service
set_clocksource.service
enabled
[root@localhost multi-user.target.wants]#
--方案
將/etc/systemd/system/multi-user.target.wants/set_clocksource.service
重新命名
mv /etc/systemd/system/multi-user.target.wants/set_clocksource.service
/etc/systemd/system/multi-user.target.wants/set_clocksource.service.bak

- 白屏再進行修復，發現建立了一個相同的檔案連結，同時報錯已修復

用OAT部署的會寫入在/etc/rc.local中
[root@10-186-57-25 ~]# cat /etc/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
