基础配置介绍
基础镜像包
- CentOS-7-x86_64-DVD-1804.iso
- chinaskills_cloud_iaas.iso
基础主机环境
主机名 | 配置 | 网卡一IP | 网卡二IP |
---|---|---|---|
controller | 4核8g100g | 192.168.100.10 | 192.168.200.10 |
compute | 2核8g100g | 192.168.100.20 | 192.168.200.20 |
注:compute节点需要两块硬盘,第二块给100g
注:如果配置不够可以适度缩减compute节点的配置
实验环境配置
注:没有特殊说明的话就是两个节点都要进行
修改主机名并映射IP
controller:
# hostnamectl set-hostname controller
# vi /etc/hosts
192.168.100.10 controller
192.168.200.10 compute
compute:
# hostnamectl set-hostname compute
# vi /etc/hosts
192.168.100.10 controller
192.168.200.10 compute
关闭防火墙
# systemctl stop firewalld
# systemctl disable frewalld
//清除防火墙规则
# iptables -F
# iptables -X
# iptables -Z
关闭NetworkManager
# systemctl stop NetworkManager
# systemctl disable NetworkManager
关闭selinux
# setenforce 0
# vi /etc/selinux/config
SELINUX=permissive
配置网络
controller:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
IPADDR="192.168.100.10"
GATEWAY="192.168.100.1"
IPV6_AUTOCONF="yes"
NETMASK="255.255.255.0"
BOOTPROTO="static"
DEVICE="eth0"
ONBOOT="yes"
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
IPADDR="192.168.200.10"
IPV6_AUTOCONF="yes"
NETMASK="255.255.255.0"
BOOTPROTO="static"
DEVICE="eth1"
ONBOOT="yes"
compute:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
IPADDR="192.168.100.20"
GATEWAY="192.168.100.1"
IPV6_AUTOCONF="yes"
NETMASK="255.255.255.0"
BOOTPROTO="static"
DEVICE="eth0"
ONBOOT="yes"
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
IPADDR="192.168.200.20"
IPV6_AUTOCONF="yes"
NETMASK="255.255.255.0"
BOOTPROTO="static"
DEVICE="eth1"
ONBOOT="yes"
注:内网卡不能配网关,否则你会发现神奇的东西
挂载镜像包
上传镜像包到controller的/opt中
# mkdir /opt/{iaas,centos}
# mount -o loop CentOS-7-x86_64-DVD-1804.iso /opt/centos
# mount -o loop chinaskills_cloud_iaas.iso /opt/iaas
为compute安装ftp服务
# yum install -y vsftpd
# vi /etc/vsftpd/vsftpd.conf
anon_root=/opt //添加
# systemctl restart vsftpd
# systemctl enable vsftpd
配置yum源
controller:
# rm -rf /etc/yum.repos.d/*
# 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
# yum clean all
# yum repolist
compute:
# rm -rf /etc/yum.repos.d/*
# 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
# yum clean all
# yum repolist
使用chrony进行时间同步
# yum install -y chrony //双节点
# vim /etc/chrony.conf //controller更改配置文件
server controller iburst
allow 192.168.100.0/24
local stratum 10
# systemctl restart chronyd //启动服务
# systemctl enable chronyd
# vim /etc/chrony.conf //添加一条按ip自动同步
server controller iburst
# systemctl restart chronyd //启动服务
# systemctl enable chronyd
将第二块硬盘分成两个50g(compute)
fdisk /dev/sdb
n
p
+50G
//重复上面操作一次
w
//重读分区表
partprobe
//查看分区状态
lsblk
开始进行安装步骤

将controller配置文件中的INTERFACE_IP改为192.168.100.20
注:检查配置文件不能出错
运行脚本进行部署
运行初始化脚本 iaas-pre-host.sh(双节点)
运行完初始化脚本重启
重启完成后重新挂载镜像或在/etc/fstab中挂载镜像
控制节点运行脚本(按步骤进行,不可跳步)
iaas-install-mysql.sh
iaas-install-keystone.sh
// keystone admin 环境变量:/etc/keystone/admin-openrc.sh
iaas-install-glance.sh
iaas-install-nova-controller.sh // 安装完可安装 compute 节点的 nova
iaas-install-neutron-controller.sh
iaas-install-dashboard.sh
// 块存储
iaas-install-cinder-controller.sh
// 对象存储
iaas-install-swift-controller.sh
// Trove 服务:需要配置好网络( flat 或 gre), 创建子网, 已安装 cinder 和 swift
iaas-install-trove.sh
// heat 编配服务
iaas-install-heat.sh
// Ceilometer 监控服务
iaas-install-ceilometer-controller.sh
// Alarm 服务
iaas-install-alarm.sh
计算节点运行脚本(按步骤进行,不可跳步)
iaas-install-nova-compute.sh // controller 安装完 keystone 时可安装
iaas-install-neutron-compute.sh
// 块存储
iaas-install-cinder-compute.sh
// 对象存储
iaas-install-swift-compute.sh
