一、架构
1、ovirt部署架构
一个标准的oVirt部署架构应包括如下三个主要部分:
2、组件架构
主要组件:
二、环境部署
1、环境信息
2、安装ovirt-engine节点
1)、安装源:
# yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2)、安装ovirt-engine
# yum install -y ovirt-engine
3).配置ovirt-engine
ovirt-engine安装完成后需要运行首次配置向导

If you choose to not configure it on this host, you have to configure it on a remote host, and then configure the engine on this host so that it can access the database of the remote Data Warehouse host. Configure Data Warehouse on this host (Yes, No) [Yes]: 回车(在本机配置数据库) Configure VM Console Proxy on this host (Yes, No) [Yes]: 回车(支持访问虚拟机的串口console通信) --== PACKAGES ==-- [ INFO ] Checking for product updates...

Note: automatic configuration of the firewall may overwrite current settings. NOTICE: iptables is deprecated and will be removed in future releases Do you want Setup to configure the firewall? (Yes, No) [Yes]: no回车(因为之前已经把防火墙服务给关掉了,所以就不用再配置防火墙的具体设置了) --== DATABASE CONFIGURATION ==-- Where is the DWH database located?

This may conflict with existing applications. Do you wish to set the application as the default page of the web server?

(Yes, No) [No]: yes回车(因为是在虚拟机上装的,内存有点小,才会提示这个) --== CONFIGURATION PREVIEW ==-- Application mode : both Default SAN wipe after delete : False Update Firewall : False Host FQDN : localhost.localdomain Configure local Engine database : True Set application as default page : True Configure Apache SSL : True Engine database secured connection : False Engine database user name : engine Engine database name : engine Engine database host : localhost Engine database port : 5432 Engine database host name validation : False Engine installation : True PKI organization : localdomain Set up ovirt-provider-ovn : True Configure WebSocket Proxy : True DWH installation : True DWH database host : localhost DWH database port : 5432 Configure local DWH database : True Configure Image I/O Proxy : True Configure VMConsole Proxy : True Please confirm installation settings (OK, Cancel) [OK]: 回车 [ INFO ] Stage: Transaction setup [ INFO ] Stopping engine service [ INFO ] Stopping ovirt-fence-kdump-listener service [ INFO ] Stopping dwh service [ INFO ] Stopping Image I/O Proxy service [ INFO ] Stopping vmconsole-proxy service [ INFO ] Stopping websocket-proxy service [ INFO ] Stage: Misc configuration [ INFO ] Stage: Package installation [ INFO ] Stage: Misc configuration [ INFO ] Upgrading CA [ INFO ] Initializing PostgreSQL [ INFO ] Creating PostgreSQL 'engine' database [ INFO ] Configuring PostgreSQL [ INFO ] Creating PostgreSQL 'ovirt_engine_history' database [ INFO ] Configuring PostgreSQL [ INFO ] Creating CA [ INFO ] Creating/refreshing DWH database schema [ INFO ] Configuring Image I/O Proxy [ INFO ] Setting up ovirt-vmconsole proxy helper PKI artifacts [ INFO ] Setting up ovirt-vmconsole SSH PKI artifacts [ INFO ] Configuring WebSocket Proxy [ INFO ] Creating/refreshing Engine database schema [ INFO ] Creating/refreshing Engine 'internal' domain database schema [ INFO ] Adding default OVN provider to database [ INFO ] Adding OVN provider secret to database [ INFO ] Setting a password for internal user admin [ INFO ] Generating post install configuration file '/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf' [ INFO ] Stage: Transaction commit [ INFO ] Stage: Closing up [ INFO ] Starting engine service [ INFO ] Starting dwh service [ INFO ] Restarting ovirt-vmconsole proxy service --== SUMMARY ==-- [ INFO ] Restarting httpd In order to configure firewalld, copy the files from /etc/ovirt-engine/firewalld to /etc/firewalld/services and execute the following commands: firewall-cmd --permanent --add-service ovirt-postgres firewall-cmd --permanent --add-service ovirt-https firewall-cmd --permanent --add-service ovn-central-firewall-service firewall-cmd --permanent --add-service ovirt-fence-kdump-listener firewall-cmd --permanent --add-service ovirt-imageio-proxy firewall-cmd --permanent --add-service ovirt-websocket-proxy firewall-cmd --permanent --add-service ovirt-http firewall-cmd --permanent --add-service ovirt-vmconsole-proxy firewall-cmd --permanent --add-service ovirt-provider-ovn firewall-cmd --reload The following network ports should be opened: tcp:2222 tcp:35357 tcp:443 tcp:5432 tcp:54323 tcp:6100 tcp:6641 tcp:6642 tcp:80 tcp:9696 udp:7410 An example of the required configuration for iptables can be found at: /etc/ovirt-engine/iptables.example Please use the user 'admin@internal' and password specified in order to login Web access is enabled at: http://localhost.localdomain:80/ovirt-engine https://localhost.localdomain:443/ovirt-engine Internal CA 95:CB:1A:EA:A7:CC:48:A3:14:8F:79:8D:BC:07:4F:98:D7:EB:B4:19 SSH fingerprint: SHA256:ltDYySFckI6bPO0OV+yzErG3YVqgA8zBnHZkEK3bWRs [WARNING] Warning: Not enough memory is available on the host.

4)、ovirt取消主机名解析,修改/etc/ovirt-engine/engine.conf.d/99-sso.conf
SSO_CALLBACK_PREFIX_CHECK=false
5)、重启ovirt-engine服务
# service ovirt-engine restart
6)、通过ovirt-engine的节点地址登录web
用户名admin
密码:上述安装过程输入的密码
3、安装计算节点
1)、安装源:
# yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2)、安装软件包
# yum -y install qemu-kvm libvirt virt-install bridge-utils vdsm
3)、启动服务并设置开机启动
# systemctl start libvirtd
# systemctl enable libvirtd
添加节点
输入节点的Ip地址和root密码
此处忽略电源管理
点击事件可以看到过程
节点正在安装过程
添加完成之后可以看到节点信息
4、配置data存储域,此处用iscsi存储(每个计算节点执行)
1)、安装源
# yum install epel* -y
# yum -y install scsi-target-utils
2)、修改配置文件/etc/tgt/targets.conf
<target iqn.2019-06.wuyeliang:target00>
backing-store /dev/sdb #数据盘
initiator-address 172.16.8.0/24 #此处用存储网段
incominguser username password #客户端登录用户名及密码
</target>
3)、配置防火墙
# firewall-cmd --add-service=iscsi-target --permanent
success
# firewall-cmd --reload
success
4)、启动服务并设置开机启动
# systemctl start tgtd
# systemctl enable tgtd
5)、查看状态
# tgtadm --mode target --op show
6)、在界面上添加存储域
添加存储信息
5、配置镜像域和导出域
1)、安装软件包
# yum -y install nfs-utils
2)、如果单独的其他节点请做以下操作
# groupadd -g 36 kvm
# useradd -u 36 -g kvm -M -d / -s /sbin/nologin vdsm
3)、创建目录并设置权限
# mkdir -p /images
# mkdir -p /export
# chown vdsm:kvm /export
# chown vdsm:kvm /images
4)、创建文件/etc/exports.d/ovirt-engine-iso-domain.exports内容如下
/images 172.16.8.0/24(rw)
/export 172.16.8.0/24(rw)
5)、启动服务
# systemctl start rpcbind nfs-server
# systemctl enable rpcbind nfs-server
6)、设置防火墙
# firewall-cmd --add-service=nfs --permanent
# firewall-cmd --add-service={nfs3,mountd,rpc-bind} --permanent
# firewall-cmd –reload
7)、添加镜像域
8)、添加导出域
6、上传镜像
将CentOS-7-x86_64-DVD-1804.iso通过ftp工具上传到ovirt-engine节点上
# engine-iso-uploader -i <ISO_DOMAIN> upload CentOS-7-x86_64-DVD-1804.iso
Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): # oVirt admin password
Uploading, please wait...
INFO: Start uploading CentOS-7-x86_64-DVD-1804.iso
Uploading: [########################################] 100%
INFO: CentOS-7-x86_64-DVD-1804.iso uploaded successfully
7、创建虚拟机
输入主机名和选择网卡
添加一块磁盘大小为80G
点击高级
设置启动项从光驱启动
点击启动
