In order to facilitate understanding of the present invention, the principle of the cluster high available service configuration method of the present invention is combined with the process of configuring the cluster high available service in the embodiment, and the cluster high available service configuration method provided by the present invention is further described below.
Specifically, the cluster high-availability service configuration method includes:
s1, setting the virtual IP of all nodes in the cluster in the configuration file, and saving the virtual IP of all nodes to the main management node.
Among the OpenStack service node deployments that are mature at present, the initial deployment is extended using three nodes running general services including databases and message queues. On this basis, network scope and server information are described in/etc/openstack _ default/openstack _ user _ config. A method for specifying network-wide and server information includes, in the above document, first updating the internal and external VIP addresses in the global _ overrates configuration section, and then adjusting the Virtual Ip (VIP) addresses of all nodes to point to the endpoint of HAProxy (the primary management node).
The method of updating the internal and external VIP addresses is as follows:
furthermore, updating the internal and external VIP addresses may also be achieved by setting a hash _ keyed _ internal _ VIP _ cid and a hash _ keyed _ external _ VIP _ cid, which correspond to the internal and external VIP addresses, respectively, and the default configuration may be seen at/etc/openstack _ default/user _ variables.
S2, designating a plurality of nodes in the configuration file as load balancing nodes.
First, nodes of different roles are defined in a cluster. In the configuration file, a plurality of nodes with excellent performance are selected as load balancing nodes according to basic parameters of all the nodes, and load balancers are operated on the load balancing nodes. After the load balancing nodes are selected, the nodes except the load balancing nodes are evenly distributed into the subordinate nodes of the load balancing nodes, and the load balancing nodes store the virtual IP of all the corresponding subordinate nodes, so that the load balancing nodes have the management authority of the subordinate nodes.
The method for configuring the load balancing node includes:
by default, HAProxy's playbook uses variables defined in/var/configs/HAProxy _ config.yml. The load balancer configuration allows for various default services such as Galera, RabbitMQ, Glance, Keystone, Neutron, Nova, Cinder, Horizon, Aodh, Gnocchi, Ceilometer. Each configuration entry in the HAProxy starts with a service label and is followed by a service name, a backend node, an SSL termination, a port, and a load balancing type. Shown below is the configuration fragment of the OpenStack mirroring service API in the HAProxy default configuration file as follows:
and S3, the binding interface of the virtual IP monitored by the main management node is appointed in the configuration file.
In the configuration file, the interfaces where Keepalived needs to be bound in the control node monitoring internal and external VIPs are specified, and the following configuration fragments are specified as Keepalived internal and external interfaces in user _ variables.
haproxy_keepalived_internal_interface:br-mgmt
haproxy_keepalived_external_interface:enp0s3
And S4, updating the configuration file to the cluster by utilizing an automatic operation and maintenance tool.
Install and update the service configuration of HAProxy and Keepalived on the main management node, run HAProxy-install.
#openstack-ansible haproxy-install.yml
The deployment of the updated nodes is limited, and then other OpenStack services which are not updated are updated, as follows:
#openstack-ansible setup-openstack.yml--limithaproxy_hosts
and invoking an automation operation and maintenance tool Ansine to update and deploy the configuration file to the OpenStack cluster.
