基于Ubuntu2310搭建openstack高可用集群B版

openstack-ha

- 环境初始化
- - 安装haproxy
  - 安装keepalived
  - 数据库集群高可用
  - rabbitmq集群高可用
  - memcache集群配置
- keystone高可用
- glance高可用
- placement高可用
- nova高可用
- neutron高可用
- horizon高可用

本实验使用两台节点master和node配置haproxy高可用，keepliaved配置主备抢占模式，三台控制节点分别搭建openstack高可用集群（数据库，消息队列，缓存，keystone，glance，placement，nova，neutron，horizon等服务），并且使三台节点同时充当计算节点

所有节点均只配置第一张网卡的IP

节点	IP	环境	配置
master	192.168.200.152	ubuntu2310	2C4G
node	192.168.200.153	ubuntu2310	2C4G
VIP	192.168.200.154	ubuntu2310	2C4G
controller01	192.168.200.155	ubuntu2310	4C4G
controller02	192.168.200.156	ubuntu2310	4C4G
controller03	192.168.200.157	ubuntu2310	4C4G

数据库集群高可用

三节点安装openstack软件包和数据库

apt install -y python3-openstackclient
apt install -y mariadb-server python3-pymysql

三节点停止数据库

systemctl stop mariadb

修改配置文件

vim /etc/mysql/mariadb.conf.d/99-openstack.cnf

[mysqld]
bind-address = 0.0.0.0
default-storage-engine = innodb
innodb_file_per_table = on

horizon高可用

双节点配置haproxy文件

cat >> /etc/haproxy/haproxy.cfg << eoflisten horizonbind 192.168.200.154:80mode tcplog globalbalance randomserver controller01 192.168.200.155:80 check inter 3000 fall 2 rise 5server controller02 192.168.200.156:80 check inter 3000 fall 2 rise 5server controller03 192.168.200.157:80 check inter 3000 fall 2 rise 5
eof

systemctl restart haproxy.service

三节点安装horizon

apt install -y openstack-dashboard

配置horizon文件，对应修改主机名

 vim /etc/openstack-dashboard/local_settings.py

OPENSTACK_HOST = "controller01" #修改主机名CACHES = {'default': {'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache','LOCATION': 'controller01:11211,controller02:11211,controller03:11211', #修改},
}

sed -i '112s/.*/SESSION_ENGINE = '\''django.contrib.sessions.backends.cache'\''/' /etc/openstack-dashboard/local_settings.py
sed -i '127s#.*#OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST#' /etc/openstack-dashboard/local_settings.py
echo "OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = False" >> /etc/openstack-dashboard/local_settings.py
echo "OPENSTACK_API_VERSIONS = {\"identity\": 3,\"image\": 2,\"volume\": 3,
}" >> /etc/openstack-dashboard/local_settings.py
echo "OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = \"Default\"" >> /etc/openstack-dashboard/local_settings.py
echo 'OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"' >> /etc/openstack-dashboard/local_settings.py
echo "OPENSTACK_CINDER_FEATURES = {'enable_backup': True
}" >> /etc/openstack-dashboard/local_settings.py
sed -i '131s/.*/TIME_ZONE = "Asia\/Shanghai"/' /etc/openstack-dashboard/local_settings.py

三节点重启

systemctl restart apache2.service

路由器高可用

需要在你的neutron.conf文件中启用l3_ha选项，然后重启你的neutron-server服务。这个选项默认是关闭的，所以你需要将其设置为True。

vim /etc/neutron/neutron.conf
[DEFAULT]
'''
l3_ha = true
'''service neutron-server restart

配置文件l3_agent.ini一般在/etc/neutron/l3_agent/目录下。在l3_agent.ini中找到或者添加以下一行:

vim /etc/neutron/l3_agent.ini
[DEFAULT]
'''
agent_mode = dvr_snat
'''service neutron-l3-agent restart

创建HA路由器

openstack router create ext-route
openstack router set --ha ext-route
