步骤1：修改主机名并更新域名解析文件
Last login: Wed Nov 11 13:46:10 2020 [root@localhost ~]# hostnamectl set-hostname "openstack.example.com" [root@localhost ~]# exec bash [root@openstack ~]# hostnamectl Static hostname: openstack.example.com Icon name: computer-vm Chassis: vm Machine ID: bf6e29e6a6de4e1b905b39e6ce142867 Boot ID: 0e5bce586aad4838a23b2d2d5a977702 Virtualization: vmware Operating System: CentOS Linux 8 (Core) CPE OS Name: cpe:/o:centos:centos:8 Kernel: Linux 4.18.0-193.el8.x86_64 Architecture: x86-64 [root@openstack ~]#
在/etc/hosts配置文件中添加主机映射关系
[root@openstack ~]# echo -e "192.168.1.126\topenstack.example.com" >> /etc/hosts [root@openstack ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.126 openstack.example.com [root@openstack ~]#
步骤2：禁用NetworkManager并使用network-scripts配置网络
[root@openstack ~]# systemctl stop NetworkManager [root@openstack ~]# systemctl disable NetworkManager Removed /etc/systemd/system/multi-user.target.wants/NetworkManager.service. Removed /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service. Removed /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
