一、环境准备

两台虚拟机，4v8g100g50g50g

centos7.5.1804 ,chinaskills_cloud_iaas.iso

controller ip :192.168.139.100

compute ip :192.168.139.110

二、搭建

1.上传镜像到虚拟机中。

[root@localhost ~]# ls
anaconda-ks.cfg  CentOS-7-x86_64-DVD-1804.iso  chinaskills_cloud_iaas.iso

2.挂载文件并复制到本地

mkdir /opt/centos && mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/ && cp -rvf /mnt/* /opt/centos/ && umount /mnt/ && mount -o loop chinaskills_cloud_iaas.iso /mnt/ && cp -rvf /mnt/* /opt/

 3.修改主机名,分别操作。

 hostnamectl set-hostname controller   
 hostnamectl set-hostname compute

4.添加映射。(都添加)

vi /etc/hosts

echo "192.168.139.100 controller" >> /etc/hosts && echo "192.168.139.110 compute" >> /etc/hosts

5.防火墙操作。

systemctl stop firewalld && systemctl disable firewalld
关闭 selinux
 sed -i 's/SELINUX=*.*/SELINUX=disabled/g' /etc/selinux/config
清楚防火墙规则
iptables -F
iptables -X
iptables -Z
/usr/sbin/iptables-save

6.配置yum源

1）移除本地自带yum源（两个节点都操作）

controller:
vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///opt/iaas-repo
gpgcheck=0
enabled=1
compute:
vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=ftp://controller/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://controller/iaas-repo
gpgcheck=0
enabled=1

2)下载vsftpd服务
 

yum install -y vsftpd && echo "anon_root=/opt" >> /etc/vsftpd/vsftpd.conf && systemctl start vsftpd && systemctl enable vsftpd

7、下载openstack基础包（两个节点）

yum install -y iaas-xiandian  # 两个节点

配置文件修改：

重启

reboot

9.基础环境的所有软件下载
