Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说
openstack先电版_云管理平台,希望能够帮助你!!!。

前言

大二上学期学习Openstack，苦于百度与CSDN上没有对应版本的教程，学的十分艰难，在此，将我的Openstack云平台搭建过程写出，留给新手学习

准备工作：

VMware Workstation Pro 虚拟机 我使用版本：15.5.2 build-

CentOS-7-x86_64-DVD-1511.iso

XianDian-IaaS-v2.2.iso

补上需要的两个镜像

提取码：bxae 
复制这段内容后打开百度网盘手机App，操作更方便哦

虚拟机配置 (controller和compute配置相同)：

内存    3G

处理器    2G

硬盘    50G

CD/DVD    CentOS-7-x86_64-DVD-1511.iso

网络适配器    VMnet1

网络适配器2  VMnet2

controller和compute网络配置

controller改主机名字，关防火墙，设置主机映射开启虚拟机

hostnamectl set-hostname controller systemctl stop firewalld systemctl disable firewalld setenforce 0 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config cat >>/etc/hosts<<eof 192.168.28.10 controller 192.168.28.20 compute eof

compute

hostnamectl set-hostname compute systemctl stop firewalld systemctl disable firewalld setenforce 0 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config cat >>/etc/hosts<<eof 192.168.28.10 controller 192.168.28.20 compute eof

controller

接下来，进入opt目录，创建挂载点 centos 以及 iaas，并使用CRT将xiandian镜像传入opt目录下

cd /opt mkdir centos iaas

设置开机自动挂载镜像文件

cat >>/etc/fstab<<eof /dev/cdrom      /opt/centos     iso9660 defaults        0       0 /opt/XianDian-IaaS-v2.2.iso     /opt/iaas   iso9660    defaults        0       0 eof

挂载立即生效

mount -a    

进入 /etc/yum.repos.d 目录，删除或移动里面的大写C开头的文件，否则后面会造成缓存错误，载创建repo源文件

cd /etc/yum.repos.d mkdir bk mv C* bk cat >>/etc/yum.repos.d/local.repo<<eof [centos] name=centos baseurl=file:///opt/centos gpgcheck=0 enabled=1 [iaas] name=iaas baseurl=file:///opt/iaas/iaas-repo gpgcheck=0 enabled=1 eof

清除缓存，生成缓存

yum clean all yum makecache

 出现提示，说明是成功了（不需要和我的完全一摸一样，因为iso版本的不同，生成的缓存也不同）

[root@controller ~]# yum makecache 已加载插件：fastestmirror centos | 3.6 kB 00:00:00 iaas | 2.9 kB 00:00:00 (1/7): centos/filelists_db | 2.9 MB 00:00:00 (2/7): centos/group_gz | 155 kB 00:00:00 (3/7): iaas/filelists_db | 1.9 MB 00:00:00 (4/7): iaas/primary_db | 2.3 MB 00:00:00 (5/7): centos/primary_db | 2.8 MB 00:00:00 (6/7): iaas/other_db | 692 kB 00:00:00 (7/7): centos/other_db | 1.2 MB 00:00:00 Determining fastest mirrors 元数据缓存已建立

注意，如果出现 下面展示 的段落信息，说明你之前的步骤出错了，可能是yum源没配置好，也可能是没挂载好，这里很坑

[root@compute yum.repos.d]# yum makecache 已加载插件：fastestmirror One of the configured repositories failed (未知), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: centos

如果是出现了 /var/run/yum.pid 的消息

执行下面这段命令即可

rm -rf /var/run/yum.pid

接下来安装vsftpd和iaas-xiandian

yum install iaas-xiandian vsftpd -y

在controller上安装 ftp（文件传输）服务
增加匿名访问

cat >>/etc/vsftpd/vsftpd.conf<<eof anon_root=/opt eof systemctl restart network systemctl start vsftpd systemctl enable vsftpd

接下来配置xiandian的openrc.sh应答文件（一个字都不能错）

sed -i 's/.//' /etc/xiandian/openrc.sh sed -i 's/PASS=/PASS=000000/g' /etc/xiandian/openrc.sh sed -i 's/HOST_IP=/HOST_IP=192.168.28.10/g' /etc/xiandian/openrc.sh sed -i 's/HOST_NAME=/HOST_NAME=controller/g' /etc/xiandian/openrc.sh sed -i 's/HOST_IP_NODE=/HOST_IP_NODE=192.168.28.20/g' /etc/xiandian/openrc.sh sed -i 's/HOST_NAME_NODE=/HOST_NAME_NODE=compute/g' /etc/xiandian/openrc.sh sed -i 's/RABBIT_USER=/RABBIT_USER=openstack/g' /etc/xiandian/openrc.sh sed -i 's/DOMAIN_NAME=/DOMAIN_NAME=demo/g' /etc/xiandian/openrc.sh sed -i 's/METADATA_SECRET=/METADATA_SECRET=000000/g' /etc/xiandian/openrc.sh sed -i 's/INTERFACE_NAME=/INTERFACE_NAME=ens34/g' /etc/xiandian/openrc.sh 

接着使用命令   cat /etc/xiandian/openrc.sh   查看配置文件，配置完后，应如下图

#--------------------system Config--------------------## #Controller Server Manager IP. example:x.x.x.x HOST_IP=192.168.28.10 #Controller Server hostname. example:controller HOST_NAME=controller #Compute Node Manager IP. example:x.x.x.x HOST_IP_NODE=192.168.28.20 #Compute Node hostname. example:compute HOST_NAME_NODE=compute #--------------------Rabbit Config ------------------## #user for rabbit. example:openstack RABBIT_USER=openstack #Password for rabbit user .example:000000 RABBIT_PASS=000000 #--------------------MySQL Config---------------------## #Password for MySQL root user . exmaple:000000 DB_PASS=000000 #--------------------Keystone Config------------------## #Password for Keystore admin user. exmaple:000000 DOMAIN_NAME=demo ADMIN_PASS=000000 DEMO_PASS=000000 #Password for Mysql keystore user. exmaple:000000 KEYSTONE_DBPASS=000000 #--------------------Glance Config--------------------## #Password for Mysql glance user. exmaple:000000 GLANCE_DBPASS=000000 #Password for Keystore glance user. exmaple:000000 GLANCE_PASS=000000 #--------------------Nova Config----------------------## #Password for Mysql nova user. exmaple:000000 NOVA_DBPASS=000000 #Password for Keystore nova user. exmaple:000000 NOVA_PASS=000000 #--------------------Neturon Config-------------------## #Password for Mysql neutron user. exmaple:000000 NEUTRON_DBPASS=000000 #Password for Keystore neutron user. exmaple:000000 NEUTRON_PASS=000000 #metadata secret for neutron. exmaple:000000 METADATA_SECRET=000000 #External Network Interface. example:eth1 INTERFACE_NAME=ens37 #First Vlan ID in VLAN RANGE for VLAN Network. exmaple:101 minvlan= #Last Vlan ID in VLAN RANGE for VLAN Network. example:200 maxvlan= #--------------------Cinder Config--------------------## #Password for Mysql cinder user. exmaple:000000 CINDER_DBPASS= #Password for Keystore cinder user. exmaple:000000 CINDER_PASS= #Cinder Block Disk. example:md126p3 BLOCK_DISK= #--------------------Trove Config--------------------## #Password for Mysql Trove User. exmaple:000000 TROVE_DBPASS= #Password for Keystore Trove User. exmaple:000000 TROVE_PASS= #--------------------Swift Config---------------------## #Password for Keystore swift user. exmaple:000000 SWIFT_PASS= #The NODE Object Disk for Swift. example:md126p4.

至此，controller停止配置，开始compute配置

compute

查看是否连接到controller的 opt/ 下面的挂载文件

[root@compute yum.repos.d]# curl ftp://192.168.28.10 -rw-r--r-- 1 0 0  Jun 04 2020 XianDian-IaaS-v2.2.iso dr-xr-xr-x 8 0 0 2048 Dec 09 2015 centos drwxr-xr-x 4 0 0 2048 Nov 06 2017 iaas

进入opt目录，创建centos和iaas文件，移动或删除大写C开头文件，创建一个ftp.repo源文件

cd /opt mkdir centos iaas cd /etc/yum.repos.d/ mkdir bk mv C* bk touch ftp.repo

进入 /etc/yum.repos.d/ftp.repo 写入

cat >>/etc/yum.repos.d/ftp.repo<<eof [centos] name=centos baseurl=ftp://192.168.28.10/centos gpgcheck=0 enabled=1 [iaas] name=iaas baseurl=ftp://192.168.28.10/iaas/iaas-repo gpgcheck=0 enabled=1 eof

清除缓存，生成缓存

yum clean all yum makecache

如出现以下画面，说明成功

[root@compute yum.repos.d]# yum makecache 已加载插件：fastestmirror centos | 3.6 kB 00:00:00 iaas | 2.9 kB 00:00:00 (1/7): centos/group_gz | 155 kB 00:00:00 (2/7): centos/filelists_db | 2.9 MB 00:00:00 (3/7): centos/primary_db | 2.8 MB 00:00:00 (4/7): centos/other_db | 1.2 MB 00:00:00 (5/7): iaas/filelists_db | 1.9 MB 00:00:00 (6/7): iaas/primary_db | 2.3 MB 00:00:00 (7/7): iaas/other_db | 692 kB 00:00:00 Determining fastest mirrors 元数据缓存已建立

下载 iaas-xiandain 进入 /etc/xiandian ，将openrc.sh 改名为openrc.sh.bk 备份 以防出现错误

再将 controller(192.168.28.10)中的 /etc/xiandian/openrc.sh 文件传输到 本机

yum -y install iaas-xiandian cd /etc/xiandian mv openrc.sh openrc.sh.bk scp 192.168.28.10:/etc/xiandian/openrc.sh openrc.sh

执行安装脚本

两个节点均执行初始化脚本

iaas-pre-host.sh

注意：执行需要一段时间，不要去按回车什么的了，在出现  【reboot】提示后，必须重启，否则之后的实例发不出去，问题很大！！！

两台均重启

reboot

重新启动虚拟机

控制节点安装 （controller）

cd /usr/local/bin cat >>/usr/local/bin/all-in-one.sh<<eof iaas-install-mysql.sh iaas-install-keystone.sh iaas-install-glance.sh iaas-install-nova-controller.sh iaas-install-neutron-controller.sh iaas-install-neutron-controller-gre.sh iaas-install-dashboard.sh eof source all-in-one.sh

计算节点安装（compute）

cd /usr/local/bin cat >>/usr/local/bin/all-in-one.sh<<eof iaas-install-nova-compute.sh iaas-install-neutron-compute.sh iaas-install-neutron-compute-gre.sh eof source all-in-one.sh

安装需要很长时间，请耐心等待

执行完成后

使用Chrome浏览器访问（其他浏览器不太好，造成访问不到）

http://控制IP/dashboard

我的控制节点IP为 192.168.28.10

所以我访问

http://192.168.28.10/dashboard

访问成功界面

域：demo

用户名：admin

密码：000000

进入

至此，Openstack云平台的安装结束
