enp9s0: 192.168.200.10
DEVICE=enp9s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.200.10
PREFIX=24
设置主机名:
hostnamectl set-hostname controller
按ctrl+d 退出 重新登陆
(2)compute 节点

enp8s0: 192.168.100.20
DEVICE=enp8s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.100.20
PREFIX=24

enp9s0: 192.168.200.20
DEVICE=enp9s0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.200.20
PREFIX=24
设置主机名:
hostnamectl set-hostname compute
按ctrl+d 退出 重新登陆
3 设置yum源
#Controller和compute节点
(1)yum源备份
#rm -rf /etc/yum.repos.d/*
(2)创建repo文件
【controller】
在/etc/yum.repos.d创建centos.repo源文件
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/iaas-repo
gpgcheck=0
enabled=1
【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
enabled=1
[iaas]
name=iaas
baseurl=ftp://controller/iaas/iaas-repo
gpgcheck=0
enabled=1
主机名映射
[root@controller ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10 controller
192.168.100.20 compute
[root@compute ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10 controller
192.168.100.20 compute
(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
[root@controller ~]# mkdir /opt/iaas
[root@controller ~]# cp -rvf /mnt/* /opt/centos/
[root@controller ~]# umount /mnt/
【挂载XianDian-IaaS-v2.4.iso】
[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# cp -rvf /mnt/* /opt/iaas
(4)搭建ftp服务器,开启并设置自启
[root@controller ~]# yum install vsftpd -y
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
添加anon_root=/opt/
保存退出
[root@controller ~]# systemctl start vsftpd
[root@controller ~]# systemctl enable vsftpd
(5)设置防火墙和Selinux
【controller/compute】
编辑selinux文件
vi /etc/selinux/config
SELINUX=permissive
[root@controller ~]# setenforce 0
关闭防火墙并设置开机不自启
systemctl stop firewalld.service
systemctl disable firewalld.service
(6)扫除缓存,验证yum源
【controller/compute】
yum clean all
yum list
4 编辑情况变量
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现实情况举行设置。

iaas-install-glance.sh
iaas-install-nova-controller.sh
iaas-install-neutron-controller.sh

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
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要选择外网网卡地点网段
2.1绑定固定网络
3 修改安全组
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
[=============================>] 100%

5 创建云主机
6 测试连接
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
±—±-----±----------±-----±----------±-----±------±------------±----------±------------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | Description |
±—±-----±----------±-----±----------±-----±------±------------±----------±------------+
| 6 | test | 2048 | 10 | 0 | | 2 | 1.0 | True | - |
±—±-----±----------±-----±----------±-----±------±------------±----------±------------
2 创建云主机网络
思绪:查看云平台创建好的网络,查看它的具体信息,用命令创建的时间,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
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

自我先容一下,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年进入阿里不停到现在。
深知大多数大数据工程师,想要提拔技能,往往是自己探索发展大概是报班学习,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,而且极易遇到天花板技术故步自封!
因此收集整理了一份《2024年大数据全套学习资料》,初志也很简单,就是盼望能够资助到想自学提拔又不知道该从何学起的朋侪。
既有得当小白学习的零基础资料,也有得当3年以上经验的小同伴深入学习提拔的进阶课程,根本涵盖了95%以上大数据开发知识点,真正体系化!
由于文件比力大,这里只是将部门目次大纲截图出来,每个节点里面都包罗大厂面经、学习笔记、源码课本、实战项目、解说视频,并且后续会持续更新
如果你觉得这些内容对你有资助,可以添加VX:vip204888 (备注大数据获取)
一个人可以走的很快,但一群人才华走的更远。不论你是正从事IT行业的老鸟或是对IT行业感爱好的新人,都欢迎扫码参加我们的的圈子(技术交换、学习资源、职场吐槽、大厂内推、面试辅导),让我们一起学习发展!
