mariadb15权限异常

SELECT User, Host FROM mysql.user WHERE Host <> 'localhost';

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'rise' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'keystone'@'%' IDENTIFIED BY 'keystone1001' WITH GRANT OPTION;

` 一定要让keystone拥有全部权限，仅仅是keystone数据表是不够的

FLUSH PRIVILEGES;

一定要重启mysql\mysql\mariadb

service mysql restart
service mariadb restart
service mysqld restart

openstack domain命令超长运行

openstack domain create --description “An Example Domain” example
执行时间超过二十分钟

GRANT ALL PRIVILEGES ON . TO ‘glance’@’%’ IDENTIFIED BY ‘glance1001’ WITH GRANT OPTION;

硬盘空间不足问题

修改官方源码： /opt/openstack-ansible/tests/roles/bootstrap-host/tasks/check-requirements.yml

该文件附属/opt/openstack-ansible/tests/bootstrap-aio.yml的playbook中，因

name: Set data disk facts
set_fact:
host_data_disk_sectors: “{ { (ansible_devices[bootstrap_host_data_disk_device][‘sectors’] | int) }}”
host_data_disk_sectorsize: “{ { (ansible_devices[bootstrap_host_data_disk_device][‘sectorsize’] | int) }}”
when:
- bootstrap_host_data_disk_device != None
  tags:
- check-disk-size

无法获取磁盘信息而出错，导致计算磁盘可用空间为0，这里附录一份相关ansible_devices信息：

非常神奇的开发者，计算用扇区乘以每个扇区大小来计算可用磁盘空间，直接读size属性就好了啊！！！（黑人问号）

再次修改：为了保持官方的一致，直接修改register

- name: Identify the space available in /
  # NOTE(hwoarang): df does not work reliably on btrfs filesystems
  # https://btrfs.wiki.kernel.org/index.php/FAQ#How_much_free_space_do_I_have.3F
  # As such, use the btrfs tools to determine the real available size on the
  # disk
  shell: |
    if [[ $(df -T / | tail -n 1 | awk '{print $2}') == "btrfs" ]]; then
        btrfs fi usage --kbytes / | awk '/^.*Free / {print $3}'| sed 's/\..*//'
    else
        df -BK / | awk '!/^Filesystem/ {print $4}' | sed 's/K//' | sed -n "2p"
    fi
  when:
    - bootstrap_host_data_disk_device == None
  changed_when: false
  register: root_space_available
  tags:
    - check-disk-size

在 else语句后追加| sed -n “2p”

googleapi下载失败问题

/etc/ansible/roles/haproxy_server/tasks/haproxy_install.yml 33 line

翻墙后使用ansible get_url也无效

手动下载放在部署机/opt/cache/files，解决

Failed to start HAProxy Load Balancer.

fatal: [infra1]: FAILED! => {“changed”: false, “msg”: “Unable to restart service haproxy: Job for haproxy.service failed because the control process exited with error code.\nSee “systemctl status haproxy.service” and “journalctl -xe” for details.\n”}

解决办法：

mkdir /run/haproxy

vim /etc/sysctl.conf #修改内核参数

net.ipv4.ip_nonlocal_bind = 1 #没有就新增此条记录

sysctl -p #保存结果，使结果生效

磁盘故障

系统无法响应，dell电脑前部指示灯已经亮起

只能手动重启，硬盘有故障，暂时无法解决

网络故障

这个没有好的办法，只能手动下载放到相应的目录下。比如一次，cdimage.ubuntu的一个base下载不了，手动下载，放到/tmp目录下。
