1. 环境配置
配置主机名
使用CRT软件连接controller节点和compute节点#xff0c;用户名默认为root#xff0c;密码默认为000000。连接上之后#xff0c;使用linux命令修改节点主机名。
[rootcontroller ~]# hostnamectl set-hostname controller
[rootcontroller …部署
1. 环境配置
配置主机名
使用CRT软件连接controller节点和compute节点用户名默认为root密码默认为000000。连接上之后使用linux命令修改节点主机名。
[rootcontroller ~]# hostnamectl set-hostname controller
[rootcontroller ~]# hostname
controller
[rootcompute ~]# hostnamectl set-hostname compute
[rootcompute ~]# hostname
compute修改完成后使用CRT软件断开重新连接controller节点和compute节点以生效新主机名。
配置域名解析
使用vi命令在controller节点与compute节点的/etc/hosts文件添加如下内容添加完成后输入:wq保存文件内容退出。
[rootcontroller ~]# vi /etc/hosts
…
192.168.200.12 controller
192.168.200.21 compute[rootcompute ~]# vi /etc/hosts
…
192.168.200.12 controller
192.168.200.21 compute对应的IP地址根据申请的云主机实际IP地址填写。
配置yum环境
将OpenStack云平台部署的iso文件通过SecureCRT上传到controller节点的/root目录下。在/opt目录生成centos7-2009和iaas-train目录将安装镜像文件内容复制到centos7-2009和iaas目录中。
[rootcontroller ~]# mkdir /opt/{centos7-2009,iaas}
[rootcontroller ~]# mount /root/CentOS-7-x86_64-DVD-2009.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[rootcontroller ~]# cp -r /mnt/* /opt/centos7-2009/
[rootcontroller ~]# umount /mnt/
[rootcontroller ~]# mount /root/chinaskills_cloud_iaas_v2.0.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[rootcontroller ~]# cp -r /mnt/* /opt/iaas/
[rootcontroller ~]# umount /mnt/
安装源文件
配置controller节点yum安装源文件yum.repo指向本地文件目录路径。
[rootcontroller ~]# mv /etc/yum.repos.d/* /media/
[rootcontroller ~]# cat /etc/yum.repos.d/yum.repo
[centos]
namecentos7-2009
baseurlfile:///opt/centos7-2009
gpgcheck0
enabled1
[openstack]
nameopenstack-train
baseurlfile:///opt/iaas/iaas-repo
gpgcheck0
enabled1

[rootcontroller ~]# yum clean all yum repolist
…
repo id repo name status
centos centos7-2009 4,070
openstack openstack-train 953
repolist: 5,023在controller节点使用yum安装vsftpd服务并将/opt目录下的文件共享出去。
安装vsftpd
[rootcontroller ~]# yum install -y vsftpd
…
Installed:vsftpd.x86_64 0:3.0.2-28.el7
Complete!
[rootcontroller ~]# echo anon_root/opt /etc/vsftpd/vsftpd.conf
[rootcontroller ~]# systemctl start vsftpd
[rootcontroller ~]# systemctl enable vsftpd【compute】
配置compute节点yum安装源文件yum.repo指向controller节点的共享文件目录路径。
[rootcompute ~]# mv /etc/yum.repos.d/* /media/
[rootcompute ~]# cat /etc/yum.repos.d/yum.repo
[centos]
