OpenStack搭建（三）组件安装

这一部分开始就是OpenStack真正意义上的正文部分了

1. 硬盘分区

在前文中，我们创建虚拟机使用了两个硬盘，一个100G一个50G，这里我们将要对这个50G硬盘进行分区，为后面运行组件安装的脚本做准备。

fdisk /dev/sdb
分出2个20G和1个5G

2. 安装ntp进行时间同步

controller节点配置：

yum -y install ntp #安装ntp服务
vi /etc/ntp.conf #进入编辑ntp的配置文件
添加以下内容（删除默认的server规则）
server 127.127.1.0
fudge 127.127.1.0 stratum 10

进行保存之后重启ntp服务并设为开机自启动

systemctl restart ntpd
systemctl enable ntpd

compute节点设置：

yum -y install ntpdate #安装ntpdate服务
systemctl enable ntpdate #设为开机自启动
ntpdate controller #同步时间

3. 预部署脚本的安装和配置

所有节点先安装先电版本的脚本包（因为iaas的ISO文件里用的是这个版本的脚本包）

yum install iaas-xiandian -y

安装之后对脚本配置文件进行修改

vi /etc/xiandian/openrc.sh  #进入脚本的配置文件

对配置文件以下内容进行一些修改

指针放在最上边最左边，按Ctrl+V然后按Shift+G最后按x键，可以一键删除第一列的“#”

HOST_IP=10.10.10.100 #controller节点IP
HOST_NAME=controller
HOST_IP_NODE=10.10.10.200 #compute节点IP
HOST_PASS_NODE=000000
HOST_NAME_NODE=compute
network_segment_IP=all #网段
RABBIT_USER=openstack
DOMAIN_NAME=demo #按照搭建要求写，我这里写demo
METADATA_SECRET=000000
INTERFACE_IP=10.10.10.100 #外网IP（compute节点就写为10.10.10.200）
INTERFACE_NAME=ens33 #外网网卡名
Physical_NAME=provider
minvlan=101
maxvlan=200
BLOCK_DISK=sdb1 #空白分区名

STORAGE_LOCAL_NET_IP=10.10.10.200 #compute节点IP

其他所有PASS都填000000
vi的命令模式下输入  :%s/PASS=/PASS=000000 #将PASS=替换为PASS=000000

修改完成之后，执行预部署脚本(温馨提示：执行这个包括后面所有脚本之前一定一定一定要设置快照或者备份！！！不要问我为什么，问就是血的教训)

iaas-pre-host.sh

执行完成这个脚本之后，需要用reboot命令重启一次。

4. 安装openstack组件

4.1 controller节点安装MySQL数据库

iaas-install-mysql.sh

4.2 controller节点安装keystone认证服务

iaas-install-keystone.sh

4.3 controller节点安装glance镜像服务

iaas-install-glance.sh

4.4 所有节点安装Nova计算服务

iaas-install-neutron-controller.sh #controller节点
iaas-install-neutron-compute.sh #compute节点

注：如果你和我一样使用的是CentOS7.9版本运行完出现依赖问题或者报错，多半是libxslt 依赖冲突（我们自带的这个依赖版本太高需要降级）
需要恢复到执行这个脚本之前的快照然后运行下面命令
# 查看可用版本
yum list libxslt --showduplicates
# 降级到 1.1.28-5.el7
sudo yum downgrade libxslt-1.1.28-5.el7

还有就是需要手动安装
sudo yum install openstack-nova-api openstack-nova-conductor openstack-nova-scheduler

运行完这些再重新运行上面的iaas-neutron脚本

4.5 controller节点安装Dashboard控制面板服务

iaas-install-dashboard.sh

4.6 浏览器访问controller节点IP进行登录

浏览器输入： controller节点IP/dashboard #比如我的就是10.10.10.100/dashboard

4.7 全部节点安装Swift对象存储服务

iaas-install-swift-controller.sh #controller节点
iaas-install-swift-compute.sh #compute节点

4.8 全部节点安装Cinder存储服务

iaas-install-cinder-controller.sh #controller节点
iaas-install-cinder-compute.sh #compute节点
