【compute】

在/etc/yum.repos.d创建centos.repo源文件

vi /etc/yum.repos.d/local.repo

[root@compute ~]# vi /etc/yum.repos.d/local.repo

[centos]

name=centos

baseurl=ftp://controller/centos

gpgcheck=0

(3)挂载iso文件

【挂载CentOS-7-x86_64-DVD-1804.iso】

[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/

[root@controller ~]# mkdir /opt/centos

systemctl stop firewalld.service

systemctl disable firewalld.service

(6)清除缓存,验证yum源

【controller/compute】

yum clean all

yum list

4 编辑环境变量


controller和compute节点

yum install iaas-xiandian -y

编辑文件/etc/xiandian/openrc.sh,此文件是安装过程中的各项参数,根据每项参数上一行的说明及服务器实际情况进行配置。

6 创建云主机


流程:

(1)管理员->资源管理->云主机类型->创建云主机类型

(2)管理员->网络->网络->创建网络

(2)项目->网络->安全组->管理规则->添加规则(ICMP、TCP、UDP)

(3)项目->资源管理->云主机->创建云主机

7 云平台创建云主机


1 创建云主机类型

在这里插入图片描述

2 创建云主机网络

选择vlan模式,网络要和外网网卡一个网段,段ID要选择外网网卡所在网段

在这里插入图片描述

2.1绑定固定网络

在这里插入图片描述

3 修改安全组

在这里插入图片描述

4 上传镜像

[root@controller ~]# source /etc/keystone/admin-openrc.sh

[root@controller ~]# glance image-create --name “CentOS7.5” --disk-format qcow2 --container-format bare --progress < /opt/iaas/images/CentOS_7.5_x86_64_XD.qcow2

8 Openstack命令创建云主机


1 创建云主机类型

使用命令创建一个名为 test ,ID为 6 ,内存为 2048MB ,磁盘为 10GB ,vcpu数量为 2 的云主机类型。

nova flavor-create test 6 2048 10 2

±—±-----±----------±-----±----------±-----±------±------------±----------±------------+

| 6 | test | 2048 | 10 | 0 | | 2 | 1.0 | True | - |

±—±-----±----------±-----±----------±-----±------±------------±----------±------------

2 创建云主机网络

思路:查看云平台创建好的网络,查看它的详细信息,用命令创建的时候,指定参数即可!

[root@controller ~]# neutron net-create --router:external --provider:network_type vlan --provider:physical_network provider --provider:segmentation_id 200 ext

自我介绍一下,小编13年上海交大毕业,曾经在小公司待过,也去过华为、OPPO等大厂,18年进入阿里一直到现在。

深知大多数大数据工程师,想要提升技能,往往是自己摸索成长或者是报班学习,但对于培训机构动则几千的学费,着实压力不小。自己不成体系的自学效果低效又漫长,而且极易碰到天花板技术停滞不前!

因此收集整理了一份《2024年大数据全套学习资料》,初衷也很简单,就是希望能够帮助到想自学提升又不知道该从何学起的朋友。

既有适合小白学习的零基础资料,也有适合3年以上经验的小伙伴深入学习提升的进阶课程,基本涵盖了95%以上大数据开发知识点,真正体系化!

由于文件比较大,这里只是将部分目录大纲截图出来,每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频,并且后续会持续更新

如果你觉得这些内容对你有帮助,可以添加VX:vip204888 (备注大数据获取)

一个人可以走的很快,但一群人才能走的更远。不论你是正从事IT行业的老鸟或是对IT行业感兴趣的新人,都欢迎扫码加入我们的的圈子(技术交流、学习资源、职场吐槽、大厂内推、面试辅导),让我们一起学习成长!
