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。
[root@controller ~]# hostnamectl set-hostname controller
[root@controller ~]# hostname
controller
[root@compute ~]# hostnamectl set-hostname compute
[root@compute ~]# 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。
[root@controller ~]# vi /etc/hosts
…
192.168.200.12 controller
192.168.200.21 compute[root@compute ~]# 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。
[root@controller ~]# mkdir /opt/{centos7-2009,iaas}
[root@controller ~]# mount /root/CentOS-7-x86_64-DVD-2009.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# cp -r /mnt/* /opt/centos7-2009/
[root@controller ~]# umount /mnt/
[root@controller ~]# mount /root/chinaskills_cloud_iaas_v2.0.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# cp -r /mnt/* /opt/iaas/
[root@controller ~]# 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。
[root@controller ~]# mv /etc/yum.repos.d/* /media/
[root@controller ~]# cat /etc/yum.repos.d/yum.repo
[centos]
name=centos7-2009
baseurl=file:///opt/centos7-2009
gpgcheck=0
enabled=1
[openstack]
name=openstack-train
baseurl=file:///opt/iaas/iaas-repo
gpgcheck=0
enabled=1
EOF
[root@controller ~]# 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
[root@controller ~]# yum install -y vsftpd
…
Installed:vsftpd.x86_64 0:3.0.2-28.el7
Complete!
[root@controller ~]# echo "anon_root=/opt" >> /etc/vsftpd/vsftpd.conf
[root@controller ~]# systemctl start vsftpd
[root@controller ~]# 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。
[root@compute ~]# mv /etc/yum.repos.d/* /media/
[root@compute ~]# cat /etc/yum.repos.d/yum.repo
[centos]
name=centos7-2009
baseurl=ftp://controller/centos7-2009
gpgcheck=0
enabled=1
[openstack]
name=openstack-train
baseurl=ftp://controller/iaas/iaas-repo
gpgcheck=0
enabled=1
EOF
[root@compute ~]# yum clean all && yum repolist
…
repo id repo name status
centos centos7-2009 4,070
openstack openstack-train 953
repolist: 5,023
划分分区
在compute节点上的临时磁盘vdb中划分两个20G的分区。
[root@compute ~]# lsblk

vda 253:0 0 100G 0 disk
└─vda1 253:1 0 100G 0 part /

[root@compute ~]# umount /mnt/
[root@compute ~]# fdisk /dev/vdb
