openstack平台搭建笔记（私有云）

一、配置虚拟机后，配置虚拟机IP地址

1.controller

vi /etc/sysconfig/network-scripts/ifcfg-ens33 (进入网卡ens33配置文件)
1

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.100.10 (ip地址)
PREFIX=24 (子网掩码)
GATEWAY=192.168.100.1 (网关)

17

配置完成后，重启network服务

systemctl restart network 
1

重启过后输入ip a 查看网卡配置信息

2.compute

vi /etc/sysconfig/network-scripts/ifcfg-ens33 (进入网卡ens33配置文件)
1

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.100.20 (ip地址)
PREFIX=24 (子网掩码)
GATEWAY=192.168.100.1 (网关)

配置完成后，重启network服务

systemctl restart network 
1

重启过后输入 ip a 命令查看网卡配置信息

二、建立主机映射

配置好IP地址后，将controller节点下，/etc/hosts 中添加 两个节点的host 如下图

之后通过scp命令将该文件传到compute节点上

scp /etc/hosts root@192.168.100.20:/etc/hosts
1

之后进入root下，隐藏目录.ssh 下如有know_host文件请删除，如果没有 输入

ssh-keygen
1

创建公钥，如下图（期间回车按默认创建）

之后选择使用ssh-copy-id 192.168.100.20命令将改公钥添加给compute节点。

之后进入compute节点重复以上操作。

三、配置yum源

首先将/etc下的/yum.repos.d的所有文件先备份到/opt下 或者其他目录下，之后在/yum.repos.d 下创建 centos.repo 文件 进行编辑

1.controller

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

2.compute

[centos]
name=centos
baseurl=ftp://192.168.100.10/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://192.168.100.10/iaas-repo
gpgcheck=0
enabled=1
1

四、挂载镜像

首先通过 CRT 将 centos 和iaas 镜像传到controller虚拟机中

传输过后，进入/root目录下，进行镜像挂载

mount -o loop chinaskills_cloud_iaas_v2.0.3.iso  /mnt (挂载iaas镜像)
1

cp -rvf /mnt/* /opt/ (复制到opt目录下)
1

umount  (解除挂载)              
1

mount -o loop CentOS-7-x86_64-DVD-2009.iso /mnt (挂载Centos镜像)
1

mkdir /opt/centos (在opt目录下创建centos目录)
1

cp -rvf /mnt/* /opt/centos/ (复制到opt/centos/目录下)
1

umount (解除挂载)
1

配置过后使用 yum clean all 清理yum源缓存 和 yum list 加载yum源

五、设置防火墙

1.controller

关闭防火墙并设置开机不自启

systemctl stop firewalld(关闭防火墙)
1

systemctl disable firewalld（设置开机不自启）
1

yum remove -y NetworkManager firewalld (卸载 NetworkManager firewalld 服务)
1

yum -y install iptables-services (安装iptables服务)
1

systemctl start iptables (启动iptables服务)
1

systemctl enable iptables (设置开机自启动)
1

iptables -Z
iptables -X
iptables -F
service iptables save (检测iptables服务是否正常运行)
1
2
3
4

设置严格访问模式

setenforce 0 (临时修改)
1

以下为永久修改 vi /etc/selinux/config 将SELINUX=enforcing改为SELINUX=disabled（或permissive）

computer同样需要操作该步骤

在controller中下载vsftpd服务使comput能够连接到controller中的镜像源

yum -y install vsftpd 
systemctl start vsftpd (启动vsftpd服务)
systemctl enable vsftpd (设置开机自启)
vi /etc/vsftpd/vsftpd.conf
在配置文件中添加
anon_root=/opt/ 保存即可 (添加过后需要重新启动vsftpd服务)
(若出现进入comput使用yum命令报错 可进入contorller中重新启动vsftpd)

六、安装openstack服务

首先使用yum命令安装openstack基础服务(compute、controller)

yun -y install openstack-iaas 
1

然后进入openstack配置文件，进行安装配置

vi /etc/openstack/openrc.sh 
1

进入之后使用ctrl+v进入视块模式，然后shift+g 到最底行，最后点击x键删除首行字母

接着输入： 进入命令模式，输入以下命令进行字符替换

:% s/PASS=/PASS=000000/g
1
