双节点部署open stack

IP	主机名	节点
192.168.200.30	controller	控制节点
192.168.200.40	compute	计算节点

一 基础设施配置

（1）两个节点虚拟机设置（controller和compute）

 （2）首先配置IP

controller节点

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eno16777736 
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
DEVICE=eno16777736
ONBOOT=yes
IPADDR=192.168.200.30
NETMASK+255.255.255.0

compute节点

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eno16777736 
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
DEVICE=eno16777736
ONBOOT=yes
IPADDR=192.168.200.40
NETMASK=255.255.255.0

（3）修改主机名

# 控制节点
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash
[root@controller ~]# 
# 计算节点
[root@localhost ~]# hostnamectl set-hostname compute
[root@localhost ~]# bash
[root@compute ~]# 

（4）上传基础镜像

[root@controller ~]# ll
total 7025752
-rw-------. 1 root root       1083 Jun  4 04:19 anaconda-ks.cfg
-rw-r--r--. 1 root root 4329570304 Jun  4 04:56 CentOS-7-x86_64-DVD-1511.iso
-rw-r--r--. 1 root root   13287936 Jun  4 04:49 cirros-0.3.3-x86_64-disk.img
-rw-r--r--. 1 root root 2851502080 Jun  4 04:55 XianDian-IaaS-v2.2.iso

（5）配置yum源

（控制节点和计算节点）

[root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/iaas
[root@controller ~]# mount CentOS-7-x86_64-DVD-1511.iso /opt/centos/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# mount XianDian-IaaS-v2.2.iso /opt/iaas/
mount: /dev/loop1 is write-protected, mounting read-only
[root@controller ~]# rm -rf /etc/yum.repos.d/*
[root@controller ~]# vi /etc/yum.repos.d/local.repo
[root@controller ~]# cat /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
[root@controller ~]# yum repolist

# compute
[root@compute ~]# rm -rf /etc/yum.repos.d/*
[root@compute ~]# vi /etc/yum.repos.d/ftp.repo
[root@compute ~]# cat /etc/yum.repos.d/ftp.repo

[iaas]

baseurl=ftp://192.168.200.40/iaas/iaas-repo
gpgcheck=0

（6）配置ftp防火墙

[root@controller ~]# yum install -y vsftpd
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf 
anon_root=/opt  ## 添加一行
[root@controller ~]# systemctl restart vsftpd
[root@controller ~]# setenforce 0
[root@controller ~]# vi /etc/selinux/config 
# 换成disabled
[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

（7）安装iaas-xiandian服务

两个节点都要安装

[root@controller ~]# yum install iaas-xiandian -y
[root@compute ~]# yum install iaas-xiandian -y

修改配置文件，完成后操作：（删除多余的#）

# 第一条，将文件中的##换成@
# 第二条，将文件中的#去掉
# 第三条，将文件中的@换回##
sed -i s/##/@/g /etc/xiandian/openrc.sh
sed -i s/#//g /etc/xiandian/openrc.sh
sed -i s/@/##/g /etc/xiandian/openrc.sh

或者用 ：%s/^#//g来删除多余的#

然后添加修改配置文件

[root@controller ~]# vi /etc/xiandian/openrc.sh
HOST_IP=192.168.200.30
HOST_NAME=controller
HOST_IP_NODE=192.168.200.40
