前言

提示：这里可以添加本文要记录的大概内容：

例如：OpenStack快速部署

提示：以下是本篇文章正文内容，下面案例可供参考

1.环境搭建

创建一台虚拟机

添加一块网卡

网卡设置成这个模式

然后在虚拟网络中查看后面用到的IP

2.安装虚拟机

3.配置基础环境

配置网卡

   转到 /etc/sysconfig/network-scripts/,看看网卡情况，也可以用  ip addr 直接查看

确认网卡后，可以通过，vi /etc/sysconfig/network-scripts/ifg-ens33


修改完后通过:wq保存退出

再修改另一张网卡

最后重启网卡 systemctl restart network

Xshell连接虚拟机

[root@localhost ~]# systemctl stop firewalld 关闭防火墙
[root@localhost ~]# systemctl disable firewalld 禁用防火墙
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0
[root@localhost ~]# vi /etc/selinux/config

[root@localhost ~]# vi /etc/hosts

[root@localhost ~]# rm -rf /etc/yum.repos.d/* 删除yum源

关闭虚拟机，克隆一份作为从节点


克隆之后的虚拟机更改网卡信息，将上面两张网卡改为20，重启网络，Xshell链接

这些配置完成之后，发送两个软件包

配置一下yum源，vi /etc/yum.repos.d/local.repo

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

创建文件夹
[root@localhost ~]# mkdir /opt/centos
[root@localhost ~]# mkdir /opt/iaas
[root@localhost ~]# ls
anaconda-ks.cfg CentOS-7-x86_64-DVD-2009.iso chinaskills_cloud_iaas.iso

compute节点也配置一下yum源
[BEGIN] 2024/11/6 16:11:27
[root@localhost ~]# rm -rf /etc/yum.repos.d/*
[root@localhost ~]# vi /etc/yum.repos.d/ftp.repo

[centos]
name=centos
enabled=1
gpgcheck=0
baseurl=ftp://192.168.102.10/centos
[iaas]
name=iaas
enabled=1
gpgcheck=0
baseurl=ftp://192.168.102.10/iaas/iaas-repo

将centos镜像临时挂在并复制到文件夹中
[root@localhost ~]# mount -o loop CentOS-7-x86_64-DVD-2009.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@localhost ~]# cp -rvf /mnt/* /opt/centos/
复制完成后，取消挂载，重新挂载另一个镜像，并复制到对应的文件夹
[root@localhost ~]# umount /mnt/
[root@localhost ~]# ^C
[root@localhost ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@localhost ~]# cp -rvf /mnt/* /opt/iaas/

最后取消挂载，删除镜像
[root@localhost ~]# rm -rf chinaskills_cloud_iaas.iso
[root@localhost ~]# rm -rf CentOS-7-x86_64-DVD-2009.iso
[root@localhost ~]# umount /mnt/
查看yum源是否做好
[root@localhost ~]# yum repolist
下在vsftpd
[root@localhost ~]# yum install vsftpd -y
修改配置
[root@localhost ~]# vi /etc/vsftpd/vsftpd.conf

[root@localhost ~]# systemctl restart vsftpd
[root@localhost ~]# systemctl enable vsftpd

下载软件包，俩个节点都要下载
[root@localhost ~]# yum install iaas-xiandian -y
[root@localhost ~]# vi /etc/xiandian/openrc.sh

修改配置文件，开始通过ctrl+v G d,取消注释 以及通过这个修改密码:%s/PASS=/PASS=201706/g

[root@localhost ~]# vi /etc/xiandian/openrc.sh
[root@localhost ~]# cat /etc/xiandian/openrc.sh
