安装openstack单节点
配置阿里
yum镜像源
rm -f /etc/yum.repos.d/*
- 在线
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo
- 离线：手动下载后上传至
/etc/yum.repos.d/
关闭防火墙
systemctl disable firewalld --now
关闭selinux
setenforce 0
sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config
关闭NetworkManager服务
systemctl disable NetworkManager --now
安装依赖
yum update -y
yum install python3-devel libffi-devel gcc openssl-devel python3-libselinux python3-pip ansible -y
配置
pip源与代理
proxy=http://xxx.xxx.xxx.xxx:8080替换为实际代理，如不需代理删除该配置项
mkdir ~/.pip
cat >> ~/.pip/pip.conf <<EOF
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
proxy=http://xxx.xxx.xxx.xxx:8080
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn
EOF
安装
kolla-ansible
pip3 install -U pip
pip3 install kolla-ansible
安装
docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl enable docker --now
配置镜像加速
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl enable docker --now
拷贝配置
mkdir -p /etc/kolla
cp -r /usr/local/share/kolla-ansible/etc_examples/kolla/* /etc/kolla
cp /usr/local/share/kolla-ansible/ansible/inventory/* /etc/kolla
修改
hostname添加解析
hostnamectl set-hostname kolla
echo '192.168.1.6 kolla' >> /etc/hosts
调整配置
- 生成
/etc/kolla/passwords.yml配置项密码
/usr/local/bin/kolla-genpwd
- 修改
keystone_admin_password值
vi /etc/kolla/passwords.yml
找到keystone_admin_password，替换值为Admin@123
- 调整网络配置
em1为宿主机网卡名称
sed -i "s;#network_interface: "eth0";network_interface: "em1";g" /etc/kolla/globals.yml
sed -i "s;#enable_haproxy: \"yes\";enable_haproxy: \"no\";g" /etc/kolla/globals.yml
192.168.1.6为宿主机IP
sed -i "s;#kolla_internal_vip_address: \"10.10.10.254\";kolla_internal_vip_address: \"192.168.1.6\";g" /etc/kolla/globals.yml
克隆
git clone https://opendev.org/openstack/openstack-ansible
新增yum源
openstack-train.repo
cat > /etc/yum.repos.d/openstack-train.repo <<EOF
[openstack-train]
name=openstack-train
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-train/
enabled=1
gpgcheck=0
EOF
kvm-common.repo
cat > /etc/yum.repos.d/kvm-common.repo <<EOF
[kvm-common]
name=kvm-common
baseurl=https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/
enabled=1
gpgcheck=0
EOF
配置yum代理
适用于主机通过代理访问互联网场景
以下变量注意替换
- username: 代理用户名
- password: 代理用户密码
- proxy_host: 代理IP地址
- proxy_port: 代理端口
echo "proxy=http://username:password@proxy_host:proxy_port" >> /etc/yum.conf
重建
yum缓存
yum clean all
yum makecache
安装
OpenStack-packstack软件包
yum -y install openstack-packstack
回退
leatherman版本
yum downgrade leatherman -y
生成默认配置
packstack --gen-answer-file=~/openstack.txt
修改
~/openstack.txt配置
修改内容如下
sed -i "s#CONFIG_SWIFT_INSTALL=y#CONFIG_SWIFT_INSTALL=n#g" ~/openstack.txt
sed -i "s#CONFIG_AODH_INSTALL=y#CONFIG_AODH_INSTALL=n#g" ~/openstack.txt
sed -i "s#CONFIG_NEUTRON_ML2_TYPE_DRIVERS=geneve,flat#CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat#g" ~/openstack.txt
sed -i "s#CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=geneve#CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan#g" ~/openstack.txt
sed -i "s#CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=ovn#CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch#g" ~/openstack.txt
手动修改项
CONFIG_COMPUTE_HOSTS=192.168.19 #计算节点ip地址
CONFIG_NEUTRON_ML2_FLAT_NETWORKS=physnet1 #flat网络这边要设置物理网卡名字
CONFIG_NEUTRON_L2_AGENT=openvswitch #L2网络的代理模式,也可选择linuxbridge
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex #这边要设置物理网卡的名字
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0 #这边br-ex:eth0是网络节点的nat网卡，到时候安装完毕之后IP地址会飘到这个上
更改主机密码（123456需要替换）
sed -i -r 's/(.+_PW)=.+/\1=123456/' openstack.txt
备份配置
cp openstack.txt openstack.txt.bak
安装
packstack --answer-file=~/openstack.txt
