openstack多节点部署运维

openstack多节点部署运维

一、packstack单点部署

1、配置虚拟机NAT网络连接

查看vmware的NAT网络默认配置

配置当前虚拟机的网络配置

配置linux网络

2、yum源配置

二、国赛双节点部署

1、准备虚拟机

创建虚拟机前，创建好vmnet2(仅主机模式),vmnet10(NAT模式)网卡，检查对应的适配器是否创建成功。准备两台vmware虚拟机，手动最小化安装2台Centos7.2系统，第一个网卡为仅主机模式，第二个网卡为NAT模式，配置CPU虚拟机，4G以上内存，50G以上硬盘。

master节点网卡：

TYPE=EthernetBOOTPROTO=staticDEFROUTE=yesPEERDNS=yesPEERROUTES=yesIPV4_FAILURE_FATAL=noIPV6INIT=yesIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_PEERDNS=yesIPV6_PEERROUTES=yesIPV6_FAILURE_FATAL=noNAME=eno16777736UUID=f34abd2e-89c9-4daf-a28c-54765164d59dDEVICE=eno16777736ONBOOT=yesIPADDR=192.168.16.10NETMASK=255.255.255.0

Node节点网卡：

TYPE=EthernetBOOTPROTO=staticDEFROUTE=yesPEERDNS=yesPEERROUTES=yesIPV4_FAILURE_FATAL=noIPV6INIT=yesIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_PEERDNS=yesIPV6_PEERROUTES=yesIPV6_FAILURE_FATAL=noNAME=eno16777736UUID=8bbcc106-d60f-48cc-aafd-2bde0154fa2eDEVICE=eno16777736ONBOOT=yesIPADDR=192.168.16.20NETMASK=255.255.255.0

2、镜像挂载

镜像上传到master节点，然后完成挂载即可。

# 挂载linux镜像cd /root/;mount -o loop CentOS-7-x86_64-DVD-1511.iso /mnt/;mkdir /opt/centos7.2;cp -rvf /mnt/* /opt/centos7.2/umount /mnt/;# 挂载iaas镜像cd /root/;mount -o loop XianDian-IaaS-v2.2.iso /mnt/;mkdir /opt/iaas;cp -rvf /mnt/* /opt/iaas;umount /mnt/;

3、本地yum配置

分别配置控制节点和计算节点的yum

# 控制节点：rm -rf /etc/yum.repos.d/CentOS-*;cat > /etc/yum.repos.d/local.repo <

# 计算节点：(如果没有可以后面再配)rm -rf /etc/yum.repos.d/CentOS-*;cat > /etc/yum.repos.d/local.repo << EOF[centos]name=centosbaseurl=ftp://192.168.16.10/centos7.2gpgcheck=0enabled=1[iaas]name=iassbaseurl=ftp://192.168.16.10/iaas/iaas-repogpgcheck=0enabled=1EOF

为计算节点提供ftp访问方式

# 控制节点——yum缓存清理yum clean allyum makecache# 控制节点——安装vsftpd和ftpyum install -y vsftpdyum install -y ftprpm -qa| grep vsftpd# 控制节点——修改vsftpd配置文件在/etc/vsftpd/vsftpd.conf中添加一行代码：anon_root=/opt# 控制节点——安装网络工具包yum install net-tools# 重启vsftpd服务systemctl restart vsftpd# 开机启动vsftpdsystemctl enable vsftpd# 控制节点、计算节点——关闭防火墙setenforce 0;iptables -F;iptables -X;iptables -Z;systemctl stop firewalld;systemctl disable firewalld;# 计算节点yum clean allyum makecache

4、给计算节点（node）添加新磁盘并分区

在vmware上给计算节点虚拟机添加一个新磁盘。虚拟机——》设置——》添加——》硬盘——》scsi模式——》创建新虚拟磁盘——》20G，拆分为多个文件——》完成

# 重启计算节点虚拟机reboot# 查看当前虚拟机的磁盘情况fdisk -l# 可以看到Disk /dev/sdb: 21.5 GB是完全空闲的# 创建两个空白磁盘空间fdisk /dev/sdb n,p,回车,回车,+10G n,p,回车,回车,回车 w

5、在controller和compute节点安装iaas-xiandian包

# 控制节点、计算节点分别执行，安装软件包yum install -y iaas-xiandian

控制节点、计算节点编辑修改配置文件/etc/xiandian/openrc.sh

6、脚本安装openstack平台

控制节点、计算节点分别执行如下脚本安装基础服务：iaas-pre-host.sh

控制节点部署mysql数据库服务：iaas-install-mysql.sh

控制节点部署keystone服务：iaas-install-keystore.sh

控制节点部署glance服务：iaas-install-glance.sh

控制节点部署nova服务：iaas-install-nova-controller.sh计算节点部署nova服务iaas-install-nova-compute.sh

控制节点部署neutroniaas-install-neutron-controller.sh错误处理——修改脚本：vi /usr/local/bin/iaas-install-neutron-controller-gre.sh将最后一行的systemctl enabled neutron-lbaas-agent 改为 systemctl enable neutron-lbaas-agent再执行下面的脚本：iaas-install-neutron-controller-gre.sh

计算节点部署neutroniaas-install-neutron-compute.shiaas-install-neutron-compute-gre.sh

控制节点部署dashboardiaas-install-dashboard.sh

三、Openstack平台使用

两节点部署，192.168.16.10为控制节点。192.168.16.20为计算节点。

1、创建镜像

# 控制节点上，找到qcow2镜像[root@controller ~]# cd /opt/iaas/images/[root@controller images]# lsCentOS_6.5_x86_64_XD.qcow2 CentOS_7.2_x86_64_XD.qcow2 MySQL_5.6_XD.qcow2# 上传镜像致Glance服务# 在控制节点，通过glance命令，将qcow2镜像上传到平台[root@controller images]# source /etc/keystone/admin-openrc.sh[root@controller images]# glance image-create --name "centos7.2" --disk-format qcow2 --container-format bare --progress < CentOS_7.2_x86_64_XD.qcow2

2、创建虚拟机

（1）创建外部网络

（2）创建内部网络

（3）创建路由器

（4）安全组配置

管理访问策略安全组，选择菜单栏 项目——》计算——》访问&安全。单击default安全组 管理规则 按钮。

（5）创建云主机

创建云主机，选择菜单栏 项目——》计算——》云主机。单击右侧 "创建云主机"按钮。

云主机名称为：test，数量：1。选择centos7.2镜像；选择m1.small资源类型；选择int-gre网络。然后单击"启动实例"按钮创建实例。

（6）连接云主机

打开CMD窗口，通过ping命令测试连通云主机。使用secureCRT工具，连接云主机，用户名：root,密码：000000。

四、Keystone服务运维

在Openstack框架中，keystone(Openstack Identity Service)的功能是负责验证身份、校验服务规则和发布服务令牌的，它实现了Openstack的Identity API.keystone可分解为两个功能：权限管理和服务目录。

1、keystone运维命令

# 环境配置source /etc/keystone/admin-openrc.sh# 创建 hqs用户openstack user create --password ps1234 --email hqs@example.com --domain demo hqs# 创建acme项目openstack project create --domain demo acme# 创建角色openstack role create compute-user# 绑定用户和项目权限# 添加的用户需要分配一定的权限，需要把用户关联绑定到对应的项目和角色openstack role add --user hqs --project acme compute-user

2、keystone查询命令

五、Nova组件详解

计算节点通过Nova Computer进行虚拟机创建，通过libvirt调用kvm创建虚拟机，nova之间通信通过rabbitMQ队列进行通信。Nova位于Openstack架构的中心，其他服务或者组件（比如Glance、Cinder、Neutron等）对它提供支持，另外它本身的架构也比较复杂。

作用：

Nova是OpenStack最核心的服务模块，负责管理和维护云计算环境的计算资源，负责整个云环境虚拟机生命周期的管理。Nova是OpenStack的计算服务，负责维护和管理的网络和存储，提供计算服务。

1、安全组相关操作：
