9-添加计算节点流程 · linux运维

[TOC] ## 流程汇总在后续使用过程中,如果要添加新的计算节点,应该在克隆完虚拟机,并做完克隆后修改项以后,再执行一下步骤 1. 配置yum源 2. 时间同步和hosts解析 3. 安装openstack基础包 4. 安装nova-compute 5. 安装neutron-linuxbridge-agent 6. 启动服务并验证 ## 具体流程 ### 1：配置yum源 1. 挂载光盘 ```sh mount /dev/cdrom /mnt echo 'mount /dev/cdrom /mnt' >>/etc/rc.local chmod +x /etc/rc.d/rc.local ``` 2. 上传rpm包并解压 ```sh cd /opt/ rz ...#上传 tar xf openstack_rpm.tar.gz ``` 3. 生成repo配置文件 ```sh cat >/etc/yum.repos.d/local.repo <<EOF [local] name=local baseurl=file:///mnt gpgcheck=0 [openstack] name=openstack baseurl=file:///opt/repo gpgcheck=0 EOF yum makecache ``` ### 2：时间同步 **时间同步:** 修改配置文件第3行为 ```sh vim /etc/chrony.conf server 10.0.0.11 iburst systemctl restart chronyd ``` **hosts解析:** 在所有节点的hosts文件中添加添加到自己的解析在本机hosts文件中添加到所有节点的解析 >如果有内部DNS则配置DNS,就不需要本步骤 ### 3：安装openstack客户端 ```sh yum install python-openstackclient openstack-selinux -y ``` ### 4：安装nova-compute **安装软件备份配置** ```sh yum install openstack-nova-compute -y yum install openstack-utils.noarch -y cp /etc/nova/nova.conf{,.bak} grep '^[a-Z\[]' /etc/nova/nova.conf.bak >/etc/nova/nova.conf my_ip=$(ip addr show dev eth0|awk -F"[ |/]+" 'NR==3 {print $3'}) ``` **非交互式配置nova** ```sh openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend rabbit openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy

none openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu ``` ### 5：安装neutron-linuxbridge-agent **安装服务备份配置** ```sh yum install openstack-neutron-linuxbridge ebtables ipset -y #备份neutron.conf \cp /etc/neutron/neutron.conf{,.bak} grep -Ev '^$|#' /etc/neutron/neutron.conf.bak >/etc/neutron/neutron.conf #备份ml2/linuxbridge_agent.ini配置 \cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak} grep '^[a-Z\[]' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak >/etc/neutron/plugins/ml2/linuxbridge_agent.ini ``` **非交互式修改neutron.conf配置** ```sh openstack-config --set /etc/neutron/neutron.conf DEFAULT rpc_backend rabbit openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_uri http://controller:5000 openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:35357 openstack-config --set

keystone_authtoken password NEUTRON_PASS openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_host controller openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_userid openstack openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_password RABBIT_PASS ``` **非交互式修改ml2/linuxbridge_agent.ini配置** ```sh openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings provider:eth0 openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group True openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan False ``` ### 6：启动服务并验证 **启动服务** ```sh systemctl enable libvirtd openstack-nova-compute neutron-linuxbridge-agent systemctl start libvirtd openstack-nova-compute neutron-linuxbridge-agent ``` **验证新节点是否可用** 创建虚机来检查新增的计算节点是否可用！ nova-scheduler 调度器
