CentOS7一键安装OpenStack

环境

CentOS 7
CPU核心数：2x2
RAM：8G
DISK：60G

问题说明

在安装openstack过程中，一直卡在下面过程：

Testing if puppet apply is finished: 192.168.100.132_controller.pp  [ | ]

等待一会儿之后会报各种不同的错误，通过搜索问题，有让修改数据库授权的，有让修改hosts文件的，有让增大内存的，还有让升级某些组件的，问题是千奇百怪，解决方法是五花八门，但是最后都没有解决问题，但是，最后我通过修改安装源为阿里云的就成功了，最后怀疑可能是因为网络问题导致资源下载缓慢或者某些资源解析不到导致的（暂未得到证实，个人思考怀疑）。

安装步骤

修改主机名;

hostnamectl set-hostname controller

将IP与controller对应关系添加到hosts文件；

[root@controller ~]# vi /etc/hosts127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4::1         localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.100.132  controller  

修改网卡配置文件；

[root@controller ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=staticDEFROUTE=yesIPV4_FAILURE_FATAL=noNAME=ens33UUID=3b1d07bf-d509-49f8-81a3-b4b16d7f190eDEVICE=ens33ONBOOT=yesIPADDR=192.168.100.132                     #配置静态IPNETMASK=255.255.255.0GATEWAY=192.168.100.2DNS1=192.168.100.2                         #配置DNS

重启网络服务；

systemctl restart network

下载阿里源；

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

重新生成缓存；

yum clean all && yum makecache

关闭防火墙;

systemctl stop firewalld && systemctl disable firewalld

编辑/etc/selinux/config的SELINUX改为disabled;

[root@controller ~]# vi /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:#     enforcing - SELinux security policy is enforced.#     permissive - SELinux prints warnings instead of enforcing.#     disabled - No SELinux policy is loaded.SELINUX=disabled                                      #修改为disabled# SELINUXTYPE= can take one of three values:#     targeted - Targeted processes are protected,#     minimum - Modification of targeted policy. Only selected processes are protected. #     mls - Multi Level Security protection.SELINUXTYPE=targeted 

再次重启下网卡服务；

systemctl restart network

通过修改openstack的baseurl为阿里云地址;

[root@controller ~]# vi /etc/yum.repos.d/CentOS-OpenStack-rocky.repo[centos-openstack-rocky]name=CentOS-7 - OpenStack rockybaseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/gpgcheck=1enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Cloudexclude=sip,PyQt4

再配置一下QEMU的baseurl为阿里云地址；

[root@controller ~]# vi /etc/yum.repos.d/CentOS-QEMU-EV.repo[centos-qemu-ev]name=CentOS-$releasever - QEMU EVbaseurl=https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=virt-kvm-common#baseurl=http://mirror.centos.org/$contentdir/$releasever/virt/$basearch/kvm-common/gpgcheck=1enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Virtualization

下面正式开始安装openstack ;

yum install -y centos-release-openstack-rockyyum -y updateyum install -y openstack-packstackpackstack --allinone

等待一会发现可以顺利安装，不再卡在 Testing if puppet apply is finished ，最后安装成功；

**** Installation completed successfully ******

在“家”目录有一个keystonerc_admin文件，执行如下；

source keystonerc_adminopenstack user list                      #测试一下是否有admin

查看admin密码；

[root@controller ~]# cat keystonerc_admin unset OS_SERVICE_TOKEN    export OS_USERNAME=admin    export OS_PASSWORD='35292e4c7abc476f'             #此为admin的密码    export OS_REGION_NAME=RegionOne    export OS_AUTH_URL=http://192.168.100.132:5000/v3    export PS1='[\u@\h \W(keystone_admin)]\$ '    export OS_PROJECT_NAME=adminexport OS_USER_DOMAIN_NAME=Defaultexport OS_PROJECT_DOMAIN_NAME=Defaultexport OS_IDENTITY_API_VERSION=3
