云盘算赛项学习————OpenStack 平台搭建
PS: 原创作品，严禁用于商业目标。如有任何技术问题，欢迎和我交流：w104118078 （微信号）一、基础环境准备
OpenStack云平台搭建需要两个节点：controller（控制节点），compute（盘算节点）
控制节点（controller）规划如下：
一块200G的硬盘。两块网卡，第一块网卡（桥接模式）IP地点利用192.168.100.100，第二块网卡（仅主机模式）IP地点利用192.168.200.100
盘算节点（compute）规划如下：
一块200G的硬盘和一块100G的硬盘。两块网卡，第一块网卡（桥接模式）IP地点利用192.168.100.200，第二块网卡（仅主机模式）IP地点利用192.168.200.200。
PS: 在VMware中将仅主机模式的DHCP服务关闭，并将网络分配地点更改为192.168.200.0 255.255.255.0
云平台搭建需要利用centos7.0版本的镜像和chinaskills_cloud_iaas.iso镜像，镜像提供如下：
centos7.0镜像链接：https://pan.baidu.com/s/1v0xOq7N6WSofosa7AEMb-A?pwd=chjx
iaas镜像链接：https://pan.baidu.com/s/1stR_BCNPUEYrIrOpzjItAA?pwd=chjx
二、搭建OpenStack云平台
controller节点配置：
## 1.controller 网络配置
# vi /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
IPADDR=192.168.100.100
NETMASK=255.255.255.0
GATEWAY=192.168.100.1
DNS1=233.5.5.5
DNS2=114.114.114.114
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=4933c159-8fcb-4646-a29f-6b5c8b4e79f
DEVICE=ens33
ONBOOT=yes
# vi /etc/sysconfig/network-scripts/ifcfg-ens34
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
IPADDR=192.168.200.100
NETMASK=255.255.255.0
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens34
UUID=932fef43-d94a-4a84-9b3f-428a85af8858
DEVICE=ens34
ONBOOT=yes
## 2.修改主机名
# hostnamectl set-hostname controller
# bash
## 3.修改 hosts 文件将 IP 地址映射为主机名
vi /etc/hosts
192.168.100.100 controller
192.168.100.200 compute
## 4.关闭防火墙
# systemctl disable firewalld
# systemctl stop firewalld
## 5.设置seLinux
SELinux有两个级别：
强制、警告
setenforce 0 ：表示警告（Permissive）
setenforce 1 ：表示强制（Enforcing）
状态分为以下三种：
SELINUX=enforcing #selinux开启，级别为强制
SELINUX=permissive #selinux开启，级别为警告
SELINUX=disabled #selinux关闭
# setenforce 0 # 临时设置等级,重启失效
# vi /etc/selinux/conf #重启后，永久生效
SELINUX=permissive
## 6.配置Yum源
上传 CentOS 7 ISO镜像文件和iaas ISO镜像文件到controller主机root目录下面
$ scp D:\chinaskills_cloud_iaas.iso root@192.168.200.100:/root
$ scp D:\CentOS-7-x86_64-DVD-1804.iso root@192.168.200.100:/root
# ls
anaconda-ks.cfgCentOS-7-x86_64-DVD-1804.isochinaskills_cloud_iaas.iso
挂载镜像到opt目录下（临时挂载，重启失效）
# mount -o loop chinaskills_cloud_iaas.iso /opt/iaas/
mount: /dev/loop is write-protected, mounting read-only
# mount -o loop CentOS-7-x86_64-DVD-1804.iso /opt/centos/
mount: /dev/loop is write-protected, mounting read-only
——————————————————————————————————————————————————————————————————————————————————————
# vi /etc/fstab # 永久挂载
/dev/mapper/centos-root / xfs defaults 0 0
UUID=fda6f1d5-b8c5-4401-a68b-b2ab67ed8370 /boot xfs defaults 0 0
/dev/mapper/centos-swap swap swap defaults 0 0
#添加以下内容

enabled=1
name=iaas
baseurl=file:///opt/iaas/iaas-repo
gpgcheck=0

# yum clean all # 清除yum源缓存
# yum repolist # 验证yum源
## 7.搭建vsftpd
# yum install -y vsftpd
# echo anon_root=/opt/ >> /etc/vsftpd/vsftpd.conf # 修改vsftp 共享服务根目录
# systemctl enable vsftpd
# systemctl start vsftpd
## 8.时间同步配置
# yum -y install chrony
# vi /etc/chrony.conf # 修改配置文件
server controller iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
allow 192.168.100.0/24
local stratum 10
logdir /var/log/chrony
# systemctl restart chronyd # 重启chrony服务
# systemctl enable chronyd # 设置开机自启动 compute节点配置：

# vi /etc/yum.repo.d/local.repo
name=centos
baseurl=ftp://controller/centos
gpgcheck=0
enabled=1
name=iaas
baseurl=ftp://controller/iaas/iaas-repo
