all-in-one部署kolla

1台虚拟机  centos7.5
两块网卡   ens33    （nat映射通外网，做管理网）
                  ens34     (做业务网)
存储不少于60G
关闭防火墙firewalld和selinux
配置主机名：hostnamectl set-hostname kolla
                   vi /etc/hosts
　　　　　　192.168.102.194　　kolla
配置互信：ssh-keygen
　　　　　ssh-copy-id -i ~/.ssh/id_rsa.pub root@kolla
配置yum源：yum install epel-release -y

 yum install python-pip
 pip install -U pip
 yum install python-devel libffi-devel gcc openssl-devel libselinux-python
 yum -y install ansible
 pip install -U ansible

编辑/etc/ansible/ansible.cfg ，修改一下内容

[defaults]
  host_key_checking=False
  pipelining=True
  forks=100

pip install kolla-ansible
cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/kolla/
cp /usr/share/kolla-ansible/ansible/inventory/*  .

修改主机变量文件：all-in-one

# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
192.168.164.129
[network]
192.168.164.129
[compute]
192.168.164.129
[storage]
localhost       ansible_connection=local

[monitoring]
localhost       ansible_connection=local

[deployment]
localhost       ansible_connection=local

编辑globals.yml文件，修改如下内容：

kolla_base_distro: "centos"
kolla_install_type: "source"
openstack_release: "queens"      #####版本可以自己定义
network_interface: "ens33"
kolla_internal_vip_address: "192.168.102.194"   ##单节点部署vip可以和管理网一样
neutron_external_interface: "ens34"
enable_cinder: "no"         ######没有后端存储，暂时禁用cinder
enable_haproxy: "no"
nova_compute_virt_type: "qemu"           全虚拟化模式
keystone_token_provider: 'fernet'

生成密码文件：kolla-genpwd
出现以下错误的解决方法：

[root@kolla ~]# kolla-genpwd
Traceback (most recent call last):
  File "/usr/bin/kolla-genpwd", line 8, in 
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/kolla_ansible/cmd/genpwd.py", line 133, in main
    fernet_keys, hmac_md5_keys)

AttributeError: 'module' object has no attribute '_ssh_write_string'

解决方法：

pip install python-openstackclient --ignore-installed pyOpenSSl

kolla-ansible -i all-in-one bootstrap-servers
kolla-ansible -i all-in-one prechecks
kolla-ansible -i all-in-one pull   #连接外网时间有点长，第一次执行若有failed，再执行一次
kolla-ansible -i deploy

生成环境变量脚本：

kolla-ansible post-deploy -i all-in-one

安装openstack命令行客户端

pip install python-openstackclient python-glanceclient python-neutronclient --ignore-installed

初始化运行环境：

. /usr/share/kolla-ansible/init-runonce

日志文件位置：/var/lib/docker/volumes/kolla_logs/_data/
销毁环境：kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it
