一：搭建前准备工作

  1. 基础环境配置 ``` controller节点

1.修改主机名

hostnamectl set-hostname controller

2.主机名映射 vi /etc/hosts 192.168.44.10 controller 192.168.44.20 compute #插入以上两行ip根据实际情况而定

3.关闭防火墙并设置开机不启动

systemctl stop firewalld

systemctl disable firewalld

4.设置selinux vi /etc/selinux/config SELINUX=disabled

compute节点 与controller节点相同，但更改主机名要为compute

  2. 2. **镜像挂载**

镜像挂载在controller节点做 1.创建用来挂载镜像的位置 [root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/openstack

2.挂载镜像 [root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /home/ [root@controller ~]# cp -rvf /home/ /opt/centos/ [root@controller ~]# umount /home/
[root@controller ~]# mount chinaskills_cloud_iaas.iso /home/
[root@controller ~]# cp -rvf /home/ /opt/openstack 

  2. 3. **Yum源配置**

controller节点：

1.由于是http模式所以下载httpd服务

yum install -y httpd

2.在httpd的/var/www/html/下创建centos,openstack目录

cd /var/www/html

mkdir centos

mkdir openstack

3.将文件拷贝到创建的两个目录中

cp -rvf /opt/centos/* /centos

cp -rvf /opt/openstack/* /openstack

4.给众多rpm包建立索引，描述各包所需依赖信息，并形成元数据

yum install -y createrepo

createrepo /var/www/html/centos

createrepo /var/www/html/openstack

5.重启httpd服务

systemctl restart httpd

6.通过浏览器访问查看情况

7.编写repo文件

cd /etc/yum.repos.d/

mkdir back

mv C* back

vi http.repo

[centos] name=centos baseurl=http://192.168.44.10/centos #ip为controller的ip gpgcheck=0 enabled=1 [openstack] name=openstack baseurl=http://192.168.44.10/openstack/iaas-repo gpgcheck=0 enabled=1

compute节点：

1.编写repo文件

cd /etc/yum.repos.d/

mkdir back

mv C* back

vi http.repo

[centos] name=centos baseurl=http://192.168.44.10/centos #ip为controller的ip gpgcheck=0 enabled=1 [openstack] name=openstack baseurl=http://192.168.44.10/openstack/iaas-repo gpgcheck=0 enabled=1

  1. <br />
  3. 4. **时间同步配置**
  5. 4.1 controller节点：

时间同步服务将controller节点作为时间同步服务器

yum install -y chrony

  1. 修改# vim /etc/chrony.conf  文件将ntp服务器改为自己供其他节点来同步时间<br />![image.png](https://cdn.nlark.com/yuque/0/2021/png/23046225/1635175887036-b46a3324-9a43-4124-9b7b-3d134d6ccf3d.png#clientId=u184e265b-84a4-4&from=paste&height=88&id=u3347327c&margin=%5Bobject%20Object%5D&name=image.png&originHeight=136&originWidth=945&originalType=binary&ratio=1&size=18461&status=done&style=none&taskId=u74d1ab1a-d290-49c7-a00d-06e9f603a0d&width=612.5)<br />![image.png](https://cdn.nlark.com/yuque/0/2021/png/23046225/1635176102201-3528d6d5-c292-4632-9050-4f3104b1b97c.png#clientId=u184e265b-84a4-4&from=paste&height=99&id=u5de11617&margin=%5Bobject%20Object%5D&name=image.png&originHeight=167&originWidth=1030&originalType=binary&ratio=1&size=15493&status=done&style=none&taskId=udb577d77-b373-4642-b9dd-425c17243ba&width=611)<br />修改后重启配置服务#  systemctl  restart chronyd<br />         4.2  compute节点：

下载chronyd服务并修改ntp源

yum install -y chrony

  1. 修改# vim /etc/chrony.conf  将ntp源改为controller<br />![image.png](https://cdn.nlark.com/yuque/0/2021/png/23046225/1635176300551-cd16aaae-62ae-4cd9-8589-1624ec4ece8a.png#clientId=u184e265b-84a4-4&from=paste&height=66&id=u1319e52f&margin=%5Bobject%20Object%5D&name=image.png&originHeight=104&originWidth=973&originalType=binary&ratio=1&size=15180&status=done&style=none&taskId=u5a389cbc-a142-4354-bc39-a0a2e05571b&width=613.5)<br />![image.png](https://cdn.nlark.com/yuque/0/2021/png/23046225/1635176309257-49270d79-f35f-4cad-9578-3ffc6aa9a69e.png#clientId=u184e265b-84a4-4&from=paste&height=67&id=u89ab2737&margin=%5Bobject%20Object%5D&name=image.png&originHeight=93&originWidth=855&originalType=binary&ratio=1&size=7738&status=done&style=none&taskId=u85b7e785-81a2-408d-a26e-1cd1eaea33f&width=617.5)<br />重启服务 #  systemctl  restart chronyd
  3. 查看compute节点同步情况<br />![image.png](https://cdn.nlark.com/yuque/0/2021/png/23046225/1635176410525-4cbeaad6-e6b3-48b1-beb1-d7539c571531.png#clientId=u184e265b-84a4-4&from=paste&height=183&id=u7d1f16c5&margin=%5Bobject%20Object%5D&name=image.png&originHeight=366&originWidth=1263&originalType=binary&ratio=1&size=49991&status=done&style=none&taskId=u485fabba-a2cb-417b-ac9a-9bd55200a0c&width=631.5)
  5. **5.计算节点分区**<br />划分磁盘第一块

[root@compute ~]# fdisk /dev/sdb Welcome to fdisk (util-linux 2.23.2).

  1. 格式化第一块磁盘

格式化磁盘 [root@compute ~]# mkfs.xfs /dev/sdb1 meta-data=/dev/sdb1 isize=512 agcount=4, agsize=6553536 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=26214144, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=12799, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0
