317. 【openstack】kolla-搭建-openstack-云环境（1）

一、准备服务器资源：

节点	IP	主机名	配置
控制节点	192.168.199.142	controller	2核4g
计算节点	192.168.199.143	compute1	2核4g

二、搭建 python3 环境

controller && compute1:
参考 314. 【Python】linux 环境搭建 python3

三、关闭防火墙和 selinux

controller && compute1:
参考 315.【Linux】云环境搭建准备——关闭防火墙

四、编辑 host 文件

controller && compute1:

五、修改主机名

controller:
hostnamectl set-hostname controller
compute1:
hostnamectl set-hostname compute1

六、新建虚拟网卡（有多网卡无需配置）

controller:
ifconfig eth33:0 10.10.0.2 up
compute1:
ifconfig eth33:0 10.10.0.3 up

七、存储节点

pvcreate /dev/sdb
#  cinder-volumes，这里跟 kolla配置文件里vg名一致
vgcreate cinder-volumes /dev/sdb

八、互信任

ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa root@controller
ssh-copy-id -i ~/.ssh/id_rsa root@compute
ssh-copy-id -i ~/.ssh/id_rsa root@network
ssh-copy-id -i ~/.ssh/id_rsa root@storage
ssh-copy-id -i ~/.ssh/id_rsa root@monitor

九、所有节点设置数据包转发

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf 
sysctl -p

十、安装 kolla-ansible、ansible

pip3 install kolla-ansible
pip3 install ansible

十一、复制 kolla-ansible 的配置

cp -r /usr/local/python39/share/kolla-ansible/etc_examples/kolla /etc/

十二、修改kolla-ansible 的全局配置

cd /etc/kolla/
vim globals.yml 

底下这些是我修改的配置

#  选择下载的基础镜像
kolla_base_distro: "centos"
#  选择的安装方法:binary二进制安装，source源码安装
kolla_install_type: "source"
#  选择OpenStack的版本标签，详细请看：https://releases.openstack.org/
openstack_release: "yoga"
#  OpenStack内部管理网络地址，通过该IP访问OpenStack Web页面进行管理。如果启用了高可用，需要设置为VIP（浮动IP）
kolla_internal_vip_address: "10.10.0.151"
#  OpenStack外部管理网络地址
kolla_external_vip_address: "192.168.199.151"
#  docker 命名空间
docker_namespace: "kolla"
#  OpenStack内部管理网络地址的网卡接口
network_interface: "ens33:0"
#  OpenStack外部（或公共）网络的网卡接口，可以是vlan模式或flat模式,此网卡应该在没有IP地址的情况下处于活动，如果不是，那么OpenStack云平台中的云主机实例将无法访问外部网络。（存在IP时br-ex桥接就不成功）
neutron_external_interface: "ens33"
#  neutron网络服务插件
neutron_plugin_agent: "openvswitch"
#  启用cinder（块存储）
enable_cinder: "yes"
#  cinder（块存储）后端启用lvm
enable_cinder_backend_lvm: "yes"
#  开启web界面
enable_horizon: "yes"
#  开启neutron网络服务
enable_neutron_provider_networks: "yes"

十三、修改密码

kolla-genpwd
#  修改 keystone_admin_password: admin 保存即可
vim /etc/kolla/passwords.yml 

十四、multinode 配置

#  These initial groups are the only groups required to be modified. The
#  additional groups are for more control of the environment.
[control]
#  These hostname must be resolvable from your deployment host
controller

#  The above can also be specified as follows:
# control[01:03]     ansible_user=kolla

#  The network nodes are where your l3-agent and loadbalancers will run
#  This can be the same as a host in the control group
[network]
network

[compute]
compute1

[monitoring]
monitor

#  When compute nodes and control nodes use different interfaces,
#  you need to comment out "api_interface" and other interfaces from the globals.yml
#  and specify like below:
# compute01 neutron_external_interface=eth0 api_interface=em1 storage_interface=em1 tunnel_interface=em1

[storage]
storage

[deployment]
localhost       ansible_connection=local

python3 -m pip install kolla
pip3 install kolla-ansible
cd /usr/local/python39/share/kolla-ansible/etc_examples/kolla/
cp -r ./* /etc/kolla
 pip3 install --upgrade setuptools
pip3 install ansible
