备注: 每个服务有2块硬盘，一块用于系统盘，一块用于glusterfs数据盘；生产环境建议系统盘做RAID 1, 两个固态硬盘做RAID 1用于GFS缓存，4块10K盘(15K SAS硬盘或SSD盘做RAID 10或RAID 5)做RAID 10；
网络环境建议最低两个1000M端口做绑定，有条件的可以上光口；注意需要先在oVirt engine管理页面做完端口绑定后再在交换机上配置物理接口端口绑定(LACP)

操作步骤

oVirt节点安装请参考https://www.cnovirt.com/archives/2739，注意不需要更新系统。
在3台node主机上设置hosts解析

[root@node100 yum.repos.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.5.100 node100.com
192.168.5.101 node101.com
192.168.5.102 node102.com
192.168.5.103 engine103.com

将3个node节点上的/etc/yum.repos.d/文件备份到backup目录下
备注: /etc/yum.repos.d目录下建议为空，否则后续安装gfs时容易报错或执行过程卡住

[root@node100 yum.repos.d]# cd /etc/yum.repos.d
[root@node100 yum.repos.d]# mkdir backup && mv *.repo backup

在其中一个node节点上设置到所有节点的ssh免密登录，此处在node100上操作

[root@node100 home]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:zblxgJtmcmXSzb1UJDZfW1H5QzUCLiXH6/Z+L3zJMvM root@node100.com
The key's randomart image is:
+---[RSA 3072]----+
|         ..+..++%|
|         o=+ o.B=|
|        o.=.+ +.o|

下载ovirt-engine-appliance-4.4-20220308105414.1.el8.x86_64.rpm并安装

[root@node100 src]# pwd

[root@node100 src]# ls

安装完成后，通过浏览器打开这台主机的Web控制台（即Cockpit），地址为：https://192.168.5.100:9090（注意IP地址替换成你实际环境的），使用root帐号登录，如下：
ovirt login
进入HostedEngine页面，点击“Hyperconverged”向导的“Start”按钮，开始部署过程，会先部署Gluster再部署HostedEngine，如下：
hosted engine
选择“Run Gluster Wizard”向导，如下：
winzard
选中“Use same hostname for Storage and Public Network”，表示为存储网和管理网使用同一个网络，因为测试环境只配置了一个网卡，然后下面分别输入Host1、Host2、Host3的域名，如下<此处根据实际情况填写，应该为node100.com, node101.com, node102.com>：
hosts
Packages这一步不用配置，直接下一步即可，如下：

Volumes步骤保持默认，下一步，如下:
volumes
Bricks这一步中，Raid Type这里我们选择“JBOD”<即直通模式>，因为我们每台主机上的数据盘是单独的一块盘，如果实际环境中是多块盘做的Raid，那么就根据实际情况选择“Raid5或者Raid6”，Blacklist Gluster Devices这里默认选中即可，下面的Device Name注意要与你环境中的实际情况对应，这里默认是“/dev/sda”，和我们测试环境是对应的，sda是我们每台主机预留出来的一块用于部署Gluster的磁盘，后面的LV Size累加起来不能超过sda的实际大小，如果有SSD盘的话，可以使用下面的“Configuer LV Cache”配置缓存盘，本次测试环境中没有多余的SSD就不配置了，Device Name下的磁盘根据实际填写, LV Size按最小的磁盘总容量进行划分,如下：
devices
下面执行部署过程即可了，这里选中“Enable Debug Logging”，以方便部署失败时排查错误原因，如下:
注意在执行安装前建议查看下3个节点上的/etc/lvm/lvm.conf，大概在390行左右将filter = [“a|^/dev/disk/by-id/lvm-pv-uuid-f91KVb-cmFk-41ty-JiUE-oB6I-Tbk1-J77Y1h$|”, “r|.*|”]注释了，如下所示:
filter
gfs wizard
部署成功如下所示，点击”Continue to Hosted Engine Deployment”继续部署HostedEngine:
在这里插入图片描述
6. hosted engine部署如下,并点击下一步
fine engine
7. 配置glusterfs并点击下一步
install gfs
8. 点击”Finish Deployment”完成engine部署
gfs2
gfs3
部署成功如下所示
finish gfs
通过SSH连接engine服务器设置主机解析

[root@engine103 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.5.100 node100.com
192.168.5.101 node101.com
192.168.5.102 node102.com
192.168.5.103 engine103.com

在C:\Windows\System32\drivers\etc\hosts中添加engine主机名解析

192.168.5.100 node100.com
192.168.5.101 node101.com
192.168.5.102 node102.com
192.168.5.103 engine103.com

访问engine web管理页面，下载CA证书并导入为”受信任的根证书颁发机构”

点击”管理门户”

使用admin和部署engine过程设置的密码登录
在”计算”->”主机”添加主机节点

点击“新建”按钮，进入新建主机弹出窗，在“常规”标签页面，输入要添加的主机的名称、主机名和root密码，在“承载的引擎”标签页面，选择“部署”（注意这里一定要选，否则HostedEngine管理虚机无法实现迁移和高可用），如下：

点确定时会弹出没有配置电源管理的提醒，这里先不配，直接点确定即可，生产环境中建议要配置电源管理，否则会影响高可用功能；使用同样的操作方法添加第三台主机；
