openstack rocky版手动增加一个计算节点

1.配置host解析

cat /etc/hosts <<EOF
0.0.0.11 controller
10.0.0.31 compute1
10.0.0.32 compute2
10.0.0.41 block1
10.0.0.51 object1
10.0.0.52 object2
EOF

2.配置yum源

yum -y install centos-release-openstack-rocky
yum -y install python-openstackclient

3.时间同步

1.安装chrony
yum -y install chrony

2.编辑chrony配置文件/etc/chrony.conf
    /删除以下4行,指定控制节点为NTP服务器
    server 0.centos.pool.ntp.org iburst
    server 1.centos.pool.ntp.org iburst
    server 2.centos.pool.ntp.org iburst
    server 3.centos.pool.ntp.org iburst
    修改为
    server controller iburst

#用以下命令修改
sed -i '3,6d' /etc/chrony.conf && sed -i '3cserver controller iburst' /etc/chrony.conf    

3.启动NTP服务并设置开机自启
systemctl enable chronyd && systemctl start chronyd

4.检查端口,监听udp323端口
$ netstat -nupl|grep chronyd
udp        0      0 127.0.0.1:323       0.0.0.0:*         1327/chronyd        
udp6       0      0 ::1:323             :::*              1327/chronyd     

5.验证,计算节点显示的是控制节点
$ chronyc sources
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^? controller                    3   6   200    50  +1319ms[+1319ms] +/-  14.4s

4.安装软件包

yum -y install openstack-nova-compute openstack-utils

6.3 配置网络选项

6.3.1 配置桥接代理

Linux网桥代理为实例构建第2层(桥接和交换)虚拟网络基础结构并处理安全组

编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件并完成以下操作

1.在本[linux_bridge]节中,将提供者虚拟网络映射到提供者物理网络接口:

使Linux操作系统内核支持网桥过滤器1

#向/etc/sysctl.d/openstack-rocky-bridge.conf写入以下内容
cat >> /etc/sysctl.d/openstack-rocky-bridge.conf <<EOF
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
EOF

#执行以下命令生效
$ modprobe br_netfilter && sysctl -p /etc/sysctl.d/openstack-rocky-bridge.conf 
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1

[neutron]
# ...
url = http://controller:9696
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS


#用以下命令修改
openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:5000
openstack-config --set /etc/nova/nova.conf neutron auth_type password

6.5 完成安装

6.5.1 重新启动Compute服务

systemctl restart openstack-nova-compute.service

6.5.2 启动Linux网桥代理并将其配置为在系统引导时启动

systemctl enable neutron-linuxbridge-agent.service && \
systemctl start neutron-linuxbridge-agent.service

6.6 验证 控制节点执行

有compute2输出并且状态为up即为正确

openstack network agent list
+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+

+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+

7.验证计算节点是否可用

  • 手动创建虚拟机并且指定调度到compute2

  • 需要先创建分组,分组在dashboard中叫主机聚合

查看主机聚合

管理员-->计算-->主机聚合

iShot2020-05-3021.35.49

创建主机聚合

创建一个名称为compute2的主机聚合,可用域也定义为compute2

iShot2020-05-3021.37.18

点击管理聚合内的主机,选择compute2,然后创建主机聚合

iShot2020-05-3021.39.53

创建完成之后可用域中就会多出一个compute2

iShot2020-05-3021.42.13

然后web界面创建虚拟机

项目-->计算-->实例-->创建实例

iShot2020-05-3021.45.34

实例名称为compute2,可用域选择compute2

iShot2020-05-3021.46.48

选择测试镜像ciiros

iShot2020-05-3021.47.48

选择实例规格,然后点击创建实例

iShot2020-05-3021.48.39

成功创建后的实例

iShot2020-05-3021.52.18

进入实例控制台,使用用户cirros、密码gocubsgo登陆,然后sudo su -切换到root用户,设置root用户密码

iShot2020-05-3021.53.38

接下来就可以使用远程连接工具连接虚拟机了
