服务器脚本搭建国基北盛openstack平台
openstack平台脚本搭建,使用国基北盛镜像
@
基础环境搭建
环境准备:
1,使用两台服务器分别作为控制节点,和计算节点,密码为000000
2,使用crt上传镜像CentOS-7-x86_64-DVD-1804.iso 和chinaskills_cloud_iaas.iso到控制节点root目录下
控制节点网卡配置

两边网卡配置完成后重启
注：其实第二张网卡可以不用配置，在neutron脚本会被修改，但是第二张网卡的网段要知道，是要用于后面云主机实例的外网卡的！
主机映射
vi /etc/hosts
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.60.2.10 controller
10.60.2.20 compute #注意主机名要在IP地址的后面
用scp命令远程传输给compute节点
scp /etc/hosts compute:/etc/hosts
3,关闭防火墙和selinux以及NetworkManager
关闭防火墙并设置开机不启动
systemctl stop firewalld && systemctl enable firewalld
关闭NetworkManager并设置开机不启动
systemctl stop NetworkManager && systemctl enable NetworkManager
临时关闭Selinux
setenforce 0
这几步后面执行pre脚本时会再做一遍的
设置yum源
创建挂载目录
mkdir /opt/
挂载yum源到/mnt/目录下再复制到/opt/下做永久挂载,也可以yum直接挂载到/opt/下
[root@controller ~]# mount /root/CentOS-7-x86_64-DVD-1804.iso /mnt
[root@controller ~]# cp -rfv /mnt/* /opt/centos
[root@controller ~]# umount /mnt/
[root@controller ~]# mount /root/chinaskills_cloud_iaas.iso /mnt
[root@controller ~]# cp -rfv /mnt/* /opt/iaas
[root@controller ~]# umount /mnt/
删除原有yum源
rm -rf /etc/yum.repos.d/*
编写yum文件
vi /etc/yum.repos.d/ftp.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
使用ftp作为远程共享
yum install -y vsftpd
在/etc/vsftpd/vsftpd.conf/下配置文件
[root@controller ~]# cat /etc/vsftpd/vsftpd.conf
# Example config file /etc/vsftpd/vsftpd.conf
anon_root=/opt #表示远程共享此节点/opt/下目录
删除compute节点原有yum源并将编写的yum文件远程传输
[root@compute ~]# rm -rf /etc/yum.repos.d/*
[root@controller ~]# scp /etc/yum.repos.d/ftp.repo compute:/etc/yum.repos.d/
[root@compute ~]# cat /etc/yum.repos.d/ftp.repo
[centos]
name=centos
baseurl=ftp://controller/centos #记得修改
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://controller/iaas/iaas-repo #记得修改
gpgcheck=0
enabled=1
验证yum源是否挂载成功
[root@controller ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: centos iaas
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors
[root@controller ~]# yum repolist

计算节点分区
使用fdisk命令在计算节点分出两块硬盘提供给cinder和swift使用
[root@compute ~]# lsblk

平台组件搭建
controller和compute同时执行,然后Crtl+D刷新,千万要执行
iaas-pre-host.sh
controller节点执行
iaas-install-mysql.sh
iaas-install-keystione.sh
iaas-install-glance.sh
iaas-install-nova-controller.sh
iaas-install-neutron-controller.sh
iaas-install-dashboard.sh
compute节点执行
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
后面的cinder,swift组件可以根据需要再进行搭建,跑完compute脚本后http://ip/dashboard访问dashboard平台
