Centos7 安装 OpenStack 遇到过的错误

以下是本人在Centos7 安装 OpenStack 遇到过的错误记录

1. ERROR : Error appeared during Puppet run: 192.168.0.153_compute.pp Error: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install openstack-ceilometer-ipmi’ returned 1: Error downloading packages:

处理：

复原错误
# yum -d 0 -e 0 -y install openstack-ceilometer-ipmi
Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

]# yum install applydeltarpm
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * centos-qemu-ev: mirrors.bupt.edu.cn
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
没有可用软件包 applydeltarpm。
错误：无须任何处理

确认一下，不再报错
# yum -d 0 -e 0 -y install openstack-ceilometer-ipmi
软件包 1:openstack-ceilometer-ipmi-10.0.1-1.el7.noarch 已安装并且是最新版本

重新安装
# packstack --answer-file=packstack-answers-......

1. ERROR : Error appeared during Puppet run: 192.168.0.151_controller.pp Error: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install python-keystoneclient’ returned 1: Error downloading packages:

处理：

# yum -d 0 -e 0 -y install python-keystoneclient

重新安装
# packstack --answer-file=packstack-answers-20221002-170651.txt 

1. ERROR : Error appeared during Puppet run: 192.168.3.77_controller.pp Error: Systemd start for openstack-nova-scheduler failed!

处理：

# cat /var/log/nova/nova-scheduler.log

命令行运行：
nova-manage api_db sync
nova-manage db sync

systemctl restart openstack-nova-scheduler.service

记得好像最后 sync 失败了，后来找个新的虚拟机从头再来过的

1. ERROR : Error appeared during Puppet run: 192.168.3.77_controller.pp Error: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install openstack-keystone’ returned 1: Error: Package: python2-qpid-proton-0.22.0-1.el7.x86_64 (centos-openstack-queens)

处理：

# yum -d 0 -e 0 -y install openstack-keystone
# yum -d 0 -e 0 -y install openstack-keystone
错误：软件包：python2-qpid-proton-0.26.0-2.el7.x86_64 (openstack-train)
          需要：qpid-proton-c(x86-64) = 0.26.0-2.el7
          可用: qpid-proton-c-0.14.0-2.el7.x86_64 (extras)

              qpid-proton-c(x86-64) = 0.37.0-1.el7
 您可以尝试添加 --skip-broken 选项来解决该问题
 您可以尝试执行：rpm -Va --nofiles --nodigest

# rpm -e --nodeps qpid-proton-c-0.26.0-2.el7

# rpm -qa qpid-proton-c

# rpm -ivh qpid-proton-c-0.26.0-2.el7

# rpm -e --nodeps qpid-proton-c-0.26.0-2.el7
错误：未安装软件包 qpid-proton-c-0.26.0-2.el7 

# yum -y install PackageKit-backend
# yum -y install yum-utils
# yum -y install qpid-proton-c-0.26.0-2.el7.x86_64

再来
# yum -d 0 -e 0 -y install openstack-keystone

不记得最后处理结果了！

1. ERROR : Failed to set RDO repo on host 192.168.3.155: RPM file seems to be installed, but appropriate repo file is probably missing in /etc/yum.repos.d/

处理：

yum install https://rdoproject.org/repos/rdo-release.rpm
竟然找不到

来回切换国内源（阿里、tuna、usdc、bupt）过程中遇到过的错误
最后下决心只使用阿里源
 # yum list centos-release-openstack* 查找源里面是否存在，并选择查询到的最新版

1. ERROR : Error appeared during Puppet run: 192.168.3.179_compute.pp Error: Systemd start for tuned failed!

处理：

# systemctl status tuned
● tuned.service
   Loaded: masked (/usr/lib/systemd/system/tuned.service; masked; vendor preset: enabled)
   Active: inactive (dead)

9月 28 10:31:10 centos7-179 systemd[1]: Cannot add dependency job for unit tuned.service, ignoring: Unit is masked.

systemctl unmask tuned 

# vim /etc/sysctl.conf
可以在这个里面增加，重启生效    
net.ipv4.ip_forward = 1

这么处理好像不管用，后来好像还是从头来过了

1. ERROR : Error appeared during Puppet run: 192.168.3.179_controller.pp Error: Cannot allocate memory - fork(2)

处理：

# free -m
          total        used        free      shared  buff/cache   available

Mem: 3789 3059 502 5 227 487
Swap: 819 356 463

没有看到内存不够啊！
当时为了重来方便，保留了好几份快照
后来直接恢复到最初的快照，并删除所有的快照，从头来过

1. ERROR : Error appeared during Puppet run: 192.168.0.159_controller.pp Error: Systemd start for httpd failed!

处理：

# systemctl status httpd.service
没有发现错误

查看日志发现有错
#  -x (回头再补上)

原来是因为着急，防火墙和 selinux 没有处理干净！

1. ERROR : Error appeared during Puppet run: 192.168.0.156_controller.pp Notice: /Stage[main]/Nova::Db::Sync/Exec[nova-db-sync]/returns: Error: (pymysql.err.OperationalError) (1045, u"Access denied for user ‘nova’@‘centos7-156’ (using password: YES)") (Background on this error at: http://sqlalche.me/e/e3q8)

后续又出现以下问题
…
Error: /Stage[main]/Nova::Db::Sync/Exec[nova-db-sync]: Failed to call refresh: ‘/usr/bin/nova-manage db sync’ returned 1 instead of one of [0]
Error: /Stage[main]/Nova::Db::Sync/Exec[nova-db-sync]: ‘/usr/bin/nova-manage db sync’ returned 1 instead of one of [0]

当时偷懒，希望一键卸载 openstack 后重装，有时候可以，有时候感觉没有卸载干净

官方文档建议找个新机器，从头来过！
