kolla-ansible 部署 openstack 遇到的问题以及解决方法
1、 ./generate_passwords.py 报错 AttributeError: 'module' object has no attribute '_ssh_write_string'
解决方法
sudo apt install python-pip
sudo pip install -U pyopenssl
2、TASK [prechecks : Checking Docker version]: The conditional check 'inventory_hostname in groups['baremetal']' failed. The error was: error while evaluating conditional (inventory_hostname in groups['baremetal']): Unable to look up a name or access an attribute in template string
解决方法：
不要注释 baremetal
[baremetal:children]
3、TASK [rabbitmq : Check if all rabbit hostnames are resolvable]: failed: [uat-ctl03] (item=uat-ctl01) => {"changed": false, "cmd": ["getent", "ahostsv4", "uat-ctl01"], "delta": "0:00:00.009165", "end": "2020-06-24 19:03:07.755371", "item": "uat-ctl01", "msg": "non-zero return code", "rc": 2, "start": "2020-06-24 19:03:07.746206", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}
解决方法：修改所有节点的 /etc/hosts 文件，增加其他节点的 hostname 解析
4、TASK [neutron : Checking if ‘MountFlags’ for docker service is set to ‘shared’]
解决方法：
gtw 节点
cat /etc/systemd/system/docker.service.d/kolla.conf
...
[Service]
MountFlags=shared
...
systemctl daemon-reload && systemctl restart docker && systemctl status docker
5、TASK [prometheus: Copying over config.json files]
解决方法：
mutinode 增加 ansible_become=yes
...
[all:vars]
ansible_user=demon
ansible_ssh_pass=123456
ansible_sudo_pass=123456
ansible_become=yes
6、安装 pip install python-openstackclient 遇到的问题
pip install python-openstackclient: Couldn't find index page for 'pbr' (maybe misspelled?)
解决方法
pip install pbr
pip install python-openstackclient:Couldn't find index page for 'setuptools_scm' (maybe misspelled?)
解决方法
pip install setuptools_scm
Collecting cmd2!=0.8.3,>=0.8.0 (from cliff!=2.9.0,>=2.8.0->python-openstackclient) Downloading /usr/lib64/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'python_requires'
解决方法
pip install --upgrade pip
pip install --upgrade setuptools
pip cannot uninstall ipaddress: “It is a distutils installed project”
解决方法
yum remove python-ipaddress
yum install pip
pip install python-openstackclient
7、openstack 使用 vlan，那么需要修改 cmp 以及 gtw 节点中的配置，重启相关 docker，否则创建外部网络 vlan 类型时，没有指定 network_vlan_ranges ，会出错
修改 gtw 节点 /etc/kolla/neutron-openvswitch-agent/ml2_conf.ini
ansible network -i ../../multinode -m shell -a "sed -i 's/^network_vlan_ranges.*/network_vlan_ranges = physnet1/' /etc/kolla/neutron-openvswitch-agent/ml2_conf.ini" --become
修改 cmp 节点 /etc/kolla/neutron-openvswitch-agent/ml2_conf.ini
ansible virtualization -i ../../multinode -m shell -a "sed -i 's/^network_vlan_ranges.*/network_vlan_ranges = physnet1/' /etc/kolla/neutron-openvswitch-agent/ml2_conf.ini" --become
重启 gtw 节点 neutron_openvswitch_agent
ansible network -i ../../multinode -m shell -a "docker restart neutron_openvswitch_agent" --become
重启 cmp 节点 neutron_openvswitch_agent
ansible virtualization -i ../../multinode -m shell -a "docker restart neutron_openvswitch_agent" --become
修改 gtw 节点 /etc/kolla/neutron-server/ml2_conf.ini
ansible network -i ../../multinode -m shell -a "sed -i 's/^network_vlan_ranges.*/network_vlan_ranges = physnet1/' /etc/kolla/neutron-server/ml2_conf.ini" --become
重启 gtw 节点 neutron_openvswitch_agent
ansible network -i ../../multinode -m shell -a "docker restart neutron_server neutron_openvswitch_agent" --become
8、修改 global.yml 或者 multinode 文件后，需要重新执行 bootstrap-servers、prechecks
9、 destroy 集群的时候出错
TASK [destroy : Destroying all Kolla containers and volumes] Docker will not be able to stop the nova_libvirt container with those running
解决方法: 用命令删除 nova_libvirt
ansible virtualization -i ../../multinode -m shell -a "docker stop nova_libvirt" --become
ansible virtualization -i ../../multinode -m shell -a "docker rm nova_libvirt" --become
