Change: 83821a11ac1d6738b63cb10878b8aaa02e153374 Merge "Address feedback from glance-remote patch" 2021-03-23 16:56:21 +0000
OS Version: CentOS Linux release 7.8.2003 (Core)
7 配置OpenStack-ironic
7.1 上传Deploy Images（控制节点）
镜像通过disk-image-create命令构建。
[root@controller ~]# glance image-create --name deploy-vmlinuz --visibility public --disk-format aki --container-format aki < coreos_production_pxe.vmlinuz
[root@controller ~]# glance image-create --name deploy-initrd --visibility public --disk-format ari --container-format ari < coreos_production_pxe_image-oem.cpio.gz
[root@controller ~]# glance image-create --name my-image.vmlinuz --visibility public --disk-format aki --container-format aki < my-image.vmlinuz
[root@controller ~]# glance image-create --name my-image.initrd --visibility public --disk-format ari --container-format ari < my-image.initrd
[root@controller ~]# export MY_VMLINUZ_UUID=$(openstack image list | awk '/my-image.vmlinuz/ { print $2 }')
[root@controller ~]# export MY_INITRD_UUID=$(openstack image list | awk '/my-image.initrd/ { print $2 }')
[root@controller ~]# glance image-create --name my-image --visibility \
public --disk-format qcow2 --container-format bare --property \
kernel_id=$MY_VMLINUZ_UUID --property ramdisk_id=$MY_INITRD_UUID < my-image.qcow2
为了OpenStack-Helm项目的快速部署、验证与研究，本次部署采用AIO（All in one）模式，因此需要注意的是，若要安装所有的功能模块至少保证服务器的内存资源不小于16G，否则可能会导致部署失败。
3.3 实施部署前的环境准备
进行实施部署前的环境准备工作，包括系统基础环境和网络代理配置。
配置Sudo免密：
noone@noone-virtual-machine:~$ chmod +w /etc/sudoers
noone@noone-virtual-machine:~$ sudo vim /etc/sudoers
noone@noone-virtual-machine:~$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL:ALL) ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
noone ALL=(ALL) NOPASSWD:ALL
#includedir /etc/sudoers.d
noone@noone-virtual-machine:~$
配置Ubuntu的软件源列表、更新系统中的软件包：
noone@noone-virtual-machine:~$ cd /etc/apt/
noone@noone-virtual-machine:/etc/apt$ cat sources.list
deb http://mirrors.163.com/ubuntu/ bionic main restricted universe multiverse

noone@noone-virtual-machine:/etc/apt$ sudo apt update
noone@noone-virtual-machine:/etc/apt$ sudo apt upgrade
noone@noone-virtual-machine:~$ sudo vim /etc/privoxy/config
......
# Suppose you are running Privoxy on an IPv6-capable machine and
# you want it to listen on the IPv6 address of the loopback
# device:
#
# listen-address [::1]:8118
#
listen-address 127.0.0.1:8118
listen-address [::1]:8118
#
......
# To chain Privoxy and Tor, both running on the same system, you
# would use something like:
#
# forward-socks5t / 127.0.0.1:9050 .
#
注释：
此处的配置，将本地转发到8118端口的流量，转发到192.168.0.60:10808，此接口是局域网中代理软件提供的
forward-socks5 / 192.168.0.60:10808 .
#
# Note that if you got Tor through one of the bundles, you may
# have to change the port from 9050 to 9150 (or even another
# one). For details, please check the documentation on the Tor
# website.
#
# The public Tor network can't be used to reach your local
# network, if you need to access local servers you therefore
# might want to make some exceptions:
#
# forward 192.168.*.*/ .
# forward 10.*.*.*/ .
# forward 127.*.*.*/ .
#
forward 192.168.*.*/ .
forward 10.*.*.*/ .
forward 127.*.*.*/ .
forward 172.24.*.*/ .
#
......
# Examples:
#
# forwarded-connect-retries 1
#
forwarded-connect-retries 1

14 常见问题
14.1 获取swift_temp_url报错
MissingAuthPlugin: An auth plugin is required to determine endpoint URL。因为我们选择了Direct的部署方式，裸机服务器的IPA会从Swift Object Storage将User Image拉到本地，在裸机端完成镜像注入，但是我们环境中没有部署Swift，所以需要改为ISCSI的部署方式。
PXE-E51: No DHCP or proxyDHCP offers were received。这是在为裸机MAC地址分配IP地址时发生的报错，主要原因是因为DHCP服务器与裸机网络不通，需要确保DHCP服务器与裸机之间可以通信。检查Neutron的配合文件，测试Provisioning网络的可用性。
