1. 通过packstack 安装Ironic 安装 ¶

本文介绍通过packstack来安装Ironic环境

通过packstack 安装Ironic 安装

1.1. 环境说明 ¶

CentOS Linux release 7.6.1810 (Core)
openstack stein

1.2. 环境准备 ¶

1.2.1. 关闭防火墙 ¶

systemctl stop firewalld
systemctl disable firewalld

1.2.2. 关闭selinx `/etc/selinux/config`¶

cat /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  #设置为disable
# 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

setenforce 0

1.3. 安装packstack ¶

注解

具体参照：https://wiki.openstack.org/wiki/Packstack

#添加packstack源
yum -y install centos-release-openstack-stein

# 安装openstack-packstack
yum -y install openstack-packstack

# 生成answer-file
packstack --gen-answer-file=packstack.cfg

1.4. 配置packstack安装文件 `packstack.cfg`¶

启用ironic，并修改ML2驱动为openvswitch

警告

packstack默认配置的是ovn ，我当前环境中使用ovn安装一直失败。因此更改为openvswitch

CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch
CONFIG_NEUTRON_L2_AGENT=openvswitch
CONFIG_IRONIC_INSTALL=y

1.5. 安装openstack ¶

#启用debug模式。方便排查安装过程中的错误信息
packstack --answer-file=packstack.cfg --debug
#安装完成后，设置环境变量
source keystonerc_admin

1.6. 配置ironic ¶

注解

通过packstack安装后，会自动配置ironic环境，我们这里了解一下配置信息。便于理解

1.6.1. keystone配置 ¶

1.6.2. nova配置 ¶

# nova配置文件
compute_driver=ironic.IronicDriver

1.7. 遇到的问题 ¶

Error: Systemd start for neutron-server failed!
journalctl log for neutron-server:

通过编辑：/usr/lib/python2.7/site-packages/paste/deploy/loadwsgi.py 解决

删除掉：return pkg_resources.EntryPoint.parse("x="+s).load(False)
添加：
ep = pkg_resources.EntryPoint.parse("x=" + s)
if hasattr(ep, 'resolve'):
   # this is available on setuptools >= 10.2
   return ep.resolve()
else:
   # this causes a DeprecationWarning on setuptools >= 11.3
   return ep.load(False)

ERROR : Error appeared during Puppet run: 10.199.32.115_controller.pp

You will find full trace in log /var/tmp/packstack/20191010-124333-hi4Rix/manifests/10.199.32.115_controller.pp.log

直接把服务全部关闭
