chinaskills_cloud_iaas.iso

openstack私有云平台搭建

镜像版本：CentOS-7-x86_64-DVD-1804.iso、chinaskills_cloud_iaas.iso

  • 虚拟机配置

==controller节点==：内存2G，处理器2个，硬盘1（100G），网卡1（仅主机192.168.100.20），网卡2（nat192.168.200.20）

==compute节点==：内存2G，处理器2个，硬盘1（100G），硬盘2（50G），硬盘3（50G），网卡1（仅主机192.168.100.40），网卡2（nat192.168.200.40）

1.配置网络

controller节点：

  4. BROWSER_ONLY=no
  5. BOOTPROTO=static
  6. DEFROUTE=yes
  7. IPV4_FAILURE_FATAL=yes
  8. IPV6INIT=yes
  9. IPV6_AUTOCONF=yes
  10. IPV6_DEFROUTE=yes

  12. IPV6_ADDR_GEN_MODE=stable-privacy
  13. NAME=ens32
  14. DEVICE=ens32
  15. ONBOOT=yes
  16. IPADDR=192.168.100.20
  17. PREFIX=24

网卡2 (NAT)

  1. [root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
  2. TYPE=Ethernet
  3. PROXY_METHOD=none
  4. BROWSER_ONLY=no
  5. BOOTPROTO=static
  6. DEFROUTE=yes
  7. IPV4_FAILURE_FATAL=yes
  8. IPV6INIT=yes
  9. IPV6_AUTOCONF=yes
  10. IPV6_DEFROUTE=yes
  11. IPV6_FAILURE_FATAL=no
  12. IPV6_ADDR_GEN_MODE=stable-privacy
  13. NAME=ens33
  14. DEVICE=ens33
  15. ONBOOT=yes
  16. IPADDR=192.168.200.20
  17. PREFIX=24
  18. GATEWAY=192.168.200.1
  19. DNS1=8.8.8.8
  20. DNS2=8.8.4.4

修改之后输入以下命令重启网络

systemctl restart network

查看是否修改成功（compute节点同理）

ip addr

compute节点

网卡1（仅主机）

  1. [root@compute ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32
  2. TYPE=Ethernet
  3. PROXY_METHOD=none
  4. BROWSER_ONLY=no
  5. BOOTPROTO=static
  6. DEFROUTE=yes
  7. IPV4_FAILURE_FATAL=yes
  8. IPV6INIT=yes
  9. IPV6_AUTOCONF=yes
  10. IPV6_DEFROUTE=yes
  11. IPV6_FAILURE_FATAL=no
  12. IPV6_ADDR_GEN_MODE=stable-privacy
  13. NAME=ens32
  14. DEVICE=ens32
  15. ONBOOT=yes
  16. IPADDR=192.168.100.40
  17. PREFIX=24

网卡2（ANT）

  1. [root@compute ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
  2. TYPE=Ethernet
  3. PROXY_METHOD=none
  4. BROWSER_ONLY=no
  5. BOOTPROTO=static
  6. DEFROUTE=yes
  7. IPV4_FAILURE_FATAL=yes
  8. IPV6INIT=yes
  9. IPV6_AUTOCONF=yes
  10. IPV6_DEFROUTE=yes
  11. IPV6_FAILURE_FATAL=no
  12. IPV6_ADDR_GEN_MODE=stable-privacy
  13. NAME=ens33
  14. DEVICE=ens33
  15. ONBOOT=yes
  16. IPADDR=192.168.200.40
  17. PREFIX=24
  18. GATEWAY=192.168.200.1
  19. DNS1=8.8.8.8
  20. DNS2=8.8.4.4

重启网络

systemctl restart network

2修改主机名并添加主机映射

controller节点：

  1. 修改主机名
  2. hostnamectl set-hostname controller
  3. 执行命令
  4. bash
  1. 添加主机映射
  2. [root@controller ~]# vi /etc/hosts
  3. 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  4. ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  5. 192.168.100.20 controller
  6. 192.168.100.40 compute
  7.  
  8. 测试是否添加成功 ping compute

compute节点：

  1. 修改主机名
  2. hostnamectl set-hostname compute
  3. bash
  1. 添加主机映射
  2. [root@controller ~]# vi /etc/hosts
  3. 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  4. ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  5. 192.168.100.20 controller
  6. 192.168.100.40 compute
  7.  
  8. 测试ping controller

3.关闭防火墙和修改selinux规则

controller节点（compute节点同理）：

  1. 关闭防火墙
  2. [root@controller ~]# systemctl stop firewalld
  3. [root@controller ~]# systemctl disable firewalld
  1. 修改selinux规则
  2. [root@controller ~]#  setenforce 0  //临时关闭selinux，关机失效
  3.  
  4. [root@controller ~]# vi /etc/selinux/config

修改这向

4.配置yum源

上传镜像并挂载镜像

将镜像上传到controller节点的home目录下

在opt文件夹下建新centos目录，将两个镜像挂载

  1. mkdir /opt/centos  //创建centos目录
  2. mount -o loop /home/CentOS-7-x86_64-DVD-1804.iso /mnt/ 
  3. cp -rvf /mnt/* /opt/centos/
  4. umount /mnt/
  5. mount -o loop /home/chinaskills_cloud_iaas.iso /mnt/
  6. cp -rvf /mnt/* /opt/
  7. umount /mnt/

删除/etc/yum.repos.d/目录下的源文件并建新local.repo文件

  1. rm -rf /etc/yum.repos.d/*
  2. vi /etc/yum.repos.d/local.repo

验证yum源是否配置成功

  1. yum makecache
  2. yum repolist

controller节点配置ftp

  1. yum -y install vsftpd
  2. 修改vsftpd配置文件
  3. vi /etc/vsftpd/vsftpd.conf
  4. anon_root=/opt/   //在最后面添加
  5. 重启vsftpd服务
  6. systemctl restart vsftpd
  7. 设置开机启动
  8. systenctl enable vsftpd

将compute节点的源文件删除，从controller节点复制过去并修改

  1. rm -rf /etc/yum.repos.d/*
  2. scp controller:/etc/yum.repos.d/local.repo /etc/yum.repos.d/
  3.  
  4. 修改local.repo文件
  5. [centos]
  6. name=centos
  7. baseurl=ftp://controller/centos
  8. gpgcheck=0
  9. enabled=1
  10.  
  11. [iaas]
  12. name=iaas
  13. baseurl=ftp://controller/iaas-repo
  14. gpgcheck=0
  15. enabled=1
  16.  
  17. yum makecache
  18. yum repolist

5.YUM源安装并修改opensrc.sh配置文件

  1. yum -y install iaas-xiandian (两个节点都要)
  2. 修改opensrc.sh文件
  3. vi /etc/xiandian/opensrc.ch
  4. 删除每行开头第一个#号
