1.编辑修改 oci-hostname.conf 文件

vi /etc/oci-hostname.conf

2.将PRESERVE_HOSTINFO=0中的的值0修改为1

# This configuration file controls the hostname persistence behavior for Oracle Linux
# compute instance on Oracle Cloud Infrastructure (formerly Baremetal Cloud Services)
# Set PRESERVE_HOSTINFO to one of the following values
#   0 -- default behavior to update hostname, /etc/hosts and /etc/resolv.conf to 
#        reflect the hostname set during instance creation from the metadata service
#   1 -- preserve user configured hostname across reboots; update /etc/hosts and 
#           /etc/resolv.conf from the metadata service  
#   2 -- preserve user configured hostname across instance reboots; no custom  
#        changes to /etc/hosts and /etc/resolv.conf from the metadata service,
#        but dhclient will still overwrite /etc/resolv.conf
#   3 -- preserve hostname and /etc/hosts entries across instance reboots; 
#        update /etc/resolv.conf from instance metadata service
PRESERVE_HOSTINFO=0

3.使用 hostnamectl set-hostname 命令修改主机名

hostnamectl set-hostname xxxxxx
