kolla安装openstack 遵照官方文档搭建的

配置主机名

hosts绑定（/etc/hosts）

192.168.41.13  kolla

 

配置yum安装依赖软件

yum install https://rdoproject.org/repos/openstack-rocky/rdo-release-rocky.rpm
yum install git ntp ntpdate openssh-server python-devel

下载openstack-ansible最新版本

git clone -b 21.0.0 https://git.openstack.org/openstack/openstack-ansible /opt/openstack-ansible   

最新版本查看 https://docs.openstack.org/openstack-ansible/latest/


下载备用存储库

git clone -b 21.0.0 https://github.com/openstack/openstack-ansible.git /mnt/openstack-ansible


安装其他软件包

yum install bridge-utils iputils lsof lvm2 chrony openssh-server tcpdump python

添加内核模块启动vlan和接口

echo 'bonding' >> /etc/modules-load.d/openstack-ansible.conf

echo '8021q' >> /etc/modules-load.d/openstack-ansible.conf

启用时间同步

systemctl enable chronyd.service

systemctl start chronyd.service

ssh生成密钥

生成密钥参考地址  https://docs.github.com/en/github/authenticating-to-github/checking-for-existing-ssh-keys

ssh-keygen

配置网络

Container management: 172.29.236.0/22 (VLAN 10)

配置存储

pvcreate --metadatasize 2048 physical_volume_device_path

vgcreate cinder-volumes physical_volume_device_path

或者

pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb　　　　　#vg名取名为 cinder-volumes，这里主要跟 kolla配置文件里vg名一致

docker的yum源配置  参考官网 https://docs.docker.com/engine/install/centos/

配置国内pipy源

mkdir ~/.pip

cat << EOF > ~/.pip/pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/
[install]
trusted-host=pypi.tuna.tsinghua.edu.cn

EOF

 

安装pip

yum -y install epel-release

yum -y install python-pip

如果pip install 出现问题可以试试命令

pip install setuptools==33.1.1

 

或者

 

安装 pip 

yum install -y python-pip
pip install -U pip -i https://mirrors.aliyun.com/pypi/simple/

python版本不兼容的问题

解决办法:

pip install --upgrade "pip < 21.0"或者curl https://bootstrap.pypa.io/2.7/get-pip.py --output get-pip.py

解决方法二

wget https://bootstrap.pypa.io/3.5/get-pip.py

python3 get-pip.py

 

二、安装基础包

 

一定要先启用EPEL的repo源
yum -y install python-devel libffi-devel gcc openssl-devel git python-pip qemu-kvm qemu-img

 

配置Docker共享挂载
mkdir /etc/systemd/system/docker.service.d 
tee /etc/systemd/system/docker.service.d/kolla.conf << 'EOF' 
[Service] 
MountFlags=shared 
EOF

 

 

 安装 ansible

pip install -U ansible -i https://mirrors.aliyun.com/pypi/simple/

 

安装 kolla-ansible  

pip install -U kolla-ansible -i https://mirrors.aliyun.com/pypi/simple/

或者

安装 kolla-ansible

 

复制相关配置文件 

cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/
cp /usr/share/kolla-ansible/ansible/inventory/* /home/

或者   

这里统一在/etc/kolla/ 目录下

 

生成密码文件 

kolla-genpwd

 或者

 

对 /etc/kolla/passwords.yml 文件生成随机密码，或者修改为自定义密码

kolla-genpwd

vim /etc/kolla/passwords.yml
##admin密码可以修改为自定义，在登录dashboard会用到
keystone_admin_password: 1234qwer

登录Dashboard，admin使用的密码，你可以根据自己需要进行修改。  

sed -i 's/^keystone_admin_password.*/keystone_admin_password: 1234qwer/' /etc/kolla/passwords.yml



硬盘虚拟化

openstack集群是通过virtualbox部署的，而virtualbox已经使用了kvm技术，所以需要设置nova的虚拟化为qemu，而不是kvm  

cat > /etc/kolla/config/nova.conf <<EOF
[libvirt]
virt_type=qemu
cpu_mode = none
EOF

 

修改容器的卷类型

cat > /etc/kolla/config/magnum.conf <<EOF
[cinder]
default_docker_volume_type = iscsi
EOF

 

如果部署前检查报错：Hostname has to resolve to IP address of api_interface

可能需要添加一下hosts

cat >> /etc/hosts <<EOF
192.168.31.248  vm248
EOF

 

编辑配置文件 

sed -i 's/^kolla_internal_vip_address:.*/kolla_internal_vip_address: "192.168.31.248"/' /etc/kolla/globals.yml
sed -i 's/^#openstack_release:.*/openstack_release: "train"/' /etc/kolla/globals.yml
sed -i 's/^#network_interface:.*/network_interface: "ens33"/' /etc/kolla/globals.yml
sed -i 's/^#neutron_external_interface:.*/neutron_external_interface: "ens37"/' /etc/kolla/globals.yml
sed -i 's/^#enable_haproxy:.*/enable_haproxy: "no"/' /etc/kolla/globals.yml
sed -i 's/^#enable_magnum:.*/enable_magnum: "yes"/' /etc/kolla/globals.yml
sed -i 's/^#enable_heat:.*/enable_heat: "yes"/' /etc/kolla/globals.yml

sed -i 's/^#enable_cinder:.*/enable_cinder: "yes"/' /etc/kolla/globals.yml
sed -i 's/^#enable_cinder_backup:.*/enable_cinder_backup: "yes"/' /etc/kolla/globals.yml
sed -i 's/^#enable_cinder_backend_lvm:.*/enable_cinder_backend_lvm: "yes"/' /etc/kolla/globals.yml

kolla_base_distro: "centos"  

kolla_install_type: "source"

sed -i `s/"nova_compute_virt_type: "kvm"/nova_compute_virt_type: "qemu"/` /etc/kolla/globals.yml

echo "kolla_internal_address: 192.168.31.248" >> /etc/kolla/globals.yml

配置主机清单文件，根据部署场景，这里选择 all-in-one 文件 

vim /etc/kolla/all-in-one

[control]
kolla
[network]
kolla
[compute]
kolla
[storage]
kolla
[monitoring]
kolla
[deployment]
kolla

Configure Ansible /etc/ansible/ansible.cfg

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

配置 ssh 无密钥登录，授权节点

ssh-keygen
ssh-copy-id -i ~/.ssh/id_rsa.pub root@kolla

##检查主机连接
ansible -i /etc/kolla/all-in-one all -m ping
##检查Bootstrap servers依赖
kolla-ansible -i /etc/kolla/all-in-one bootstrap-servers
##检查配置
kolla-ansible -i /etc/kolla/all-in-one prechecks
##pull镜像
kolla-ansible pull -i /etc/kolla/all-in-one
##执行部署
kolla-ansible -i /etc/kolla/all-in-one deploy

登录 dashboard  

http://192.168.72.131     账号密码   admin   密码在/etc/kolla/passwords.yml   keystone的密码就可以登陆
