openstack单机部署未完成

阅读原文时间：2023年07月09日阅读：2

注：centos8单机版

注：本次实验手动配置密码均为admin

环境准备：配置hosts文件

192.168.116.85为本机IP

echo '192.168.116.85 controller vip myip' >> /etc/hosts
yum upgrade -y

禁用防火墙与selinux

systemctl disable firewalld --now
sed -i '/^SELINUX=/s/enforcing/disabled/' /etc/selinux/config
setenforce 0

注：网络组件与NetworkManager冲突，所有网络上需要禁用NetworkManager，启用network服务

# 安装Network服务
dnf install network-scripts -y

停用NetworkManager并禁止开机自启

systemctl stop NetworkManager && systemctl disable NetworkManager

启用 Network并设置开机自启

systemctl start network && systemctl enable network
#如果启用network报错，执行如下命令
/usr/lib/systemd/systemd-sysv-install enable network

1. 更换yum源

wget http://mirrors.aliyun.com/repo/Centos-8.repo

2. 下载openstack源

yum install -y centos-release-openstack-ussuri

sed -i 's/^mirrorlist=http:\/\/mirrorlist.centos.org/#mirrorlist=http:\/\/mirrorlist.centos.org/g' /etc/yum.repos.d/C*
sed -i 's/^#baseurl=http:\/\/mirror.centos.org/baseurl=https:\/\/vault.centos.org/g' /etc/yum.repos.d/C*
sed -i 's/gpgcheck=1/gpgcheck=0/g' /etc/yum.repos.d/C*

yum config-manager --set-enabled powertools
yum install -y python3-openstackclient
yum install -y openstack-selinux

3. 本地数据库配置

bind-address=127.0.0.1 #只允许本机访问。
bind-address=某个网卡的ip #例如bind-address=192.168.116.85，只能通过ip为192.168.116.85的网卡访问。
bind-address=0.0.0.0 #此规则是系统默认配置，监听所有网卡，即允许所有ip访问。

yum install -y mariadb mariadb-server python3-PyMySQL

cat > /etc/my.cnf.d/openstack.cnf << EOF
[mysqld]
bind-address = 192.168.116.85
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
EOF

systemctl enable mariadb --now

mysql_secure_installation

4. 配置rabbitmq

　　遇到报错：缺libSDL2，erlang安装失败，rabbitmq安装失败；

　　尝试单独下载erlang源，再次安装，依然失败：curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh|sh；失败后删除本操作产生的额外erlang源

　　解决：wget https://pkgs.dyn.su/el8/extras/x86_64/SDL2-2.0.14-5.el8.x86_64.rpm;yum -y install SDL2-2.0.14-5.el8.x86_64.rpm 或yum -y upgrade试试

yum install -y rabbitmq-server
systemctl enable rabbitmq-server --now

rabbitmqctl add_user openstack openstack

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

5. 配置memcached

注：192.168.116.8为本机IP

yum install -y memcached python3-memcached

sed -i 's/OPTIONS=".*"/OPTIONS="-l 127.0.0.1,::1,192.168.116.85"/' /etc/sysconfig/memcached

systemctl enable memcached --now

6. 配置etcd

单节点可不部署

yum install -y etcd

7. 配置keystone

报错：
openstack token issue
Failed to discover available identity versions when contacting http://vip:5000/v3. Attempting to parse version from URL.
Unexpected exception for http://vip:5000/v3/auth/tokens: Failed to parse: http://vip:5000/v3/auth/tokens

解决：
yum -y upgrade

systemctl enable openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy

实验的时候发现了一个很好用的ini配置文件编辑工具：crudini

[libvirt]
#virt_type = kvm #物理机配置openstack
#virt_type = qemu #虚拟机配置openstack
####（官方：虚拟机必须配置libvirt为使用qemu而不是kvm。）####

yum install -y openstack-nova-compute
yum install -y crudini

crudini --set /etc/nova/nova.conf vnc server_listen '0.0.0.0'
crudini --set /etc/nova/nova.conf vnc novncproxy_base_url http://VIP:6080/vnc_auto.html
crudini --set /etc/nova/nova.conf libvirt virt_type qemu
discover_hosts_in_cells_interval = 300

先启动：
systemctl restart libvirtd-tcp.socket
再启动：
systemctl enable libvirtd openstack-nova-compute
systemctl restart libvirtd openstack-nova-compute

openstack compute service list --service nova-compute

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

验证：
openstack compute service list
openstack catalog list
openstack image list
nova-status upgrade check
