openstack单机部署 未完成
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
