OpenStack Train Offline deployment | 6.2 Compute Node -Nova Computing service component

Service components nova-install nova-controller -install nova-compute -install nova-install-verify Install OpenStack(Rocky edition)-05 on CentOS7. Install a Nova compute node instance. Train Installation Guide Series

Install and configure nova-related software

1. Install the Nova software

yum install openstack-nova-compute -y
yum install python-openstackclient openstack-selinux -y
#For quick configuration
yum install openstack-utils -y 
Copy the code

2. Modify the configuration file

/etc/nova_nova. conf Run the following commands in sequence to write the files to the script and execute the script

cd
touch compute-node-nova.conf.sh
vim compute-node-nova.conf.sh
bash compute-node-nova.conf.sh
Copy the code

Sh contents of the compute-node-nova.conf.sh file

bash compute-node-nova.conf.sh
Copy the code

Note: Configure the [neutron] section of /etc/nova/nova.conf. Refer to the Networking service install guide for more details. The server component listens for the IP addresses of all network adapters on the local computer, while the proxy component listens for the IP addresses of the management network interfaces on the local computer. After the installation is complete, modify the following parameters: novNCproxy_base_URL indicates the IP address, and the IP address indicates the supplier address. If multiple IP addresses exist except for the management network, select an appropriate one as the external access address.

It - config - set/etc/nova/nova. Conf VNC novncproxy_base_url http://192.168.232.101:6080/vnc_auto.htmlCopy the code

3. Check whether the compute node supports VM hardware acceleration

First determine if your compute node supports hardware acceleration for your virtual machine,

egrep -c '(vmx|svm)' /proc/cpuinfo
Copy the code

(1) If 0 is returned, the compute node does not support hardware acceleration. In this case, run the following command to configure libvirt to use QEMU:

openstack-config --set  /etc/nova/nova.conf libvirt virt_type  qemu
egrep -v "^#|^$" /etc/nova/nova.conf|grep 'virt_type'
Copy the code

In addition, if OpenStack is set up in VMware, configure libvirt as qemu. ② If other values are returned, the compute node supports hardware acceleration and does not require additional configuration. Run the following command:

openstack-config --set  /etc/nova/nova.conf libvirt virt_type  kvm 
egrep -v "^#|^$" /etc/nova/nova.conf|grep 'virt_type'
Copy the code

4. Start the computing service and configure it to start upon startup

Two services need to be started

systemctl start libvirtd.service openstack-nova-compute.service 
systemctl status libvirtd.service openstack-nova-compute.service
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl list-unit-files |grep libvirtd.service
systemctl list-unit-files |grep openstack-nova-compute.service
Copy the code

Note: (1) If the nova-compute service cannot be started, check /var/log/nova-nova-compute. The error message may indicate that the firewall on the controller node is blocking access to port 5672. Configure the firewall on the controller node to enable port 5672 on the controller node and restart services on the compute node. (2) Controller node

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl status firewalld.service

systemctl restart rabbit_server.service
systemctl restart rabbitmq-server.service
systemctl status rabbitmq-server.service
firewall-cmd --zone=public --add-port=5672/tcp --permanent
systemctl restart firewalld
firewall-cmd --zone=public --query-port=5672/tcp
Copy the code
