安装操作步骤

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.localdomain6192.168.1.126   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 NetworkManagerRemoved /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.

安装network-scripts

在openstack中启动实例之前，首先必须创建网络，路由器和上传镜像。因此，让我们首先使用以下neutron命令在管理租户中创建外部网络。
