practical! ! Openstack one-click deployment steps

1. Environmental requirements

CentOS 7.6 system
CPU: dual-core dual-threaded/virtualization enabled
memory: 4G
hard disk: 30G+300G
network card: NAT mode
option: (press the Tab key on the installation interface to enter the interface editing, enter the content behind) net.ifnames=0 biosdevname= 0 (can be modified to eth0 network card when created)

Two, environment configuration

1. Configure static address and host name

vi /etc/sysconfig/network-scripts/ifcfg-eth0
......
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.50
NETMASK=255.255.255.0
GATEWAY=192.168.200.2
DNS1=192.168.200.2
DNS2=8.8.8.8

#在/etc/resolv.conf中添加：
vi /etc/resolv.conf
nameserver 114.114.114.114
#重启网卡
systmectl restart network

2. Turn off (set not to start after booting) firewall, core protection, NetworkManager

systemctl stop firewalld
systemctl disable firewalld
systemctl stop NetworkManager
setenforce 0

3. Install the time synchronization service, synchronize the Alibaba Cloud clock server (ntp1, ntp2...), set up periodic tasks, and set up automatic startup

yum install -y ntpdate
ntpdate ntp.aliyun.com >>/var/log/ntpdate.log
crontab -e
....

4. Configure yum source

[root@openstack ~]# cd /etc/yum.repos.d/
[root@openstack yum.repos.d]# mkdir bak
[root@openstack yum.repos.d]# mv C* bak/
[root@openstack yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@openstack yum.repos.d]# yum -y install centos-release-openstack-train
[root@openstack yum.repos.d]# yum clean all
[root@openstack yum.repos.d]# yum makecache (fast)		#（）部分可选择添加

5. Restart and view service status

reboot

6. Download the OpenStack management toolkit and deploy OpenStack online

yum -y install openstack-packstack
packstack --allinone

Additional information:
 * Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS or FWaaS services. Geneve will be used as the encapsulation method for tenant networks
 * A new answerfile was created in: /root/packstack-answers-20201018-191715.txt
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.226.150. To use the command line tools you need to source the file.
