在 CentOS Stream 9/Rocky Linux 9 上安装 oVirt 引擎

2024-07-04 Linux 59

oVirt 是一款免费使用的开源虚拟化管理解决方案，其开发由 Red Hat 支持。 oVirt 是为管理 KVM（基于内核的虚拟机）虚拟化环境而构建的。它附带的功能使您能够通过基于 Web 的集中管理界面来管理存储、网络和虚拟机。

oVirt 项目的关键组件是 oVirt Engine 和 oVirt Node。 oVirt Engine 是一个提供图形用户界面和 REST API 的组件，用于管理虚拟化环境中的所有资源。您可以在运行 Enterprise Linux 的物理机或虚拟机上安装 oVirt Engine。

本文将提供在 CentOS Stream 9/Rocky Linux 9 Linux 系统上手动安装独立 oVirt Engine 的指南。必须在运行名为 engine-setup 的脚本之前安装操作系统，该脚本将执行 oVirt 引擎的配置。设置完成后，您可以添加计算主机并配置用于运行虚拟机的存储。

以下是在独立虚拟机或专用服务器上安装 oVirt Engine 的硬件要求。

Resource	Minimum	Recommended
CPU	A dual core x86_64 CPU.	A quad core x86_64 CPU or multiple dual core x86_64 CPUs.
Memory	4 GB of available system RAM if Data Warehouse is not installed and if memory is not being consumed by existing processes.	16 GB of system RAM.
Hard Disk	25 GB of locally accessible, writable disk space.	50 GB of locally accessible, writable disk space.You can use the RHV Engine History Database Size Calculator to calculate the appropriate disk space for the Engine history database size.
Network Interface	1 Network Interface Card (NIC) with bandwidth of at least 1 Gbps.	1 Network Interface Card (NIC) with bandwidth of at least 1 Gbps.

1. 拉取更新并设置ntp

登录到您的 Linux 服务器实例。

ssh root@ServerIP or username@ServerIP

运行以下命令以确保所有系统软件包都是最新的。

sudo dnf -y update

应用内核更新时，需要重新启动。

sudo reboot

更改当前使用的时区

sudo timedatectl set-timezone your_time_zone

要列出所有可用时区，请在 shell 提示符下键入以下内容：

timedatectl list-timezones

要将时区更改为非洲/内罗毕，我将输入：

sudo timedatectl set-timezone Africa/Nairobi

还可以启用系统时钟与远程服务器的自动同步。

sudo timedatectl set-ntp yes

安装 Chrony 时间同步。

sudo dnf -y install chrony
sudo systemctl enable --now chronyd

手动同步时间。

sudo chronyc sources

确认您的系统本地时间值。

$ timedatectl
               Local time: Thu 2024-02-08 10:36:19 EAT
           Universal time: Thu 2024-02-08 07:36:19 UTC
                 RTC time: Thu 2024-02-08 07:36:19
                Time zone: Africa/Nairobi (EAT, +0300)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

2.添加oVirt引擎RPM存储库

让我们启用包含 oVirt Engine 包的正确存储库。

sudo dnf install -y centos-release-ovirt45

预期安装输出：

对于 Rocky Linux 9，更新存储库配置文件以将 $stream 替换为 9-stream。这将使我们能够在 Rocky Linux 9 系统上使用 CentOS Stream 9 存储库。

更新缓存元数据。

sudo dnf makecache -y

3.安装oVirt引擎

为机器设置正确的主机名。

sudo hostnamectl set-hostname ovirt.mylab.io

将 IP 及其主机名添加到 /etc/hosts 文件中。

$ sudo vim /etc/hosts
ovirt.mylab.io 192.168.1.8

现在我们已经配置了所需的存储库，让我们安装 oVirt 引擎的软件包和依赖项。

sudo dnf install ovirt-engine

当提示继续时接受安装。

4.配置oVirt引擎

要配置 oVirt Engine，我们需要运行 engine-setup 命令：

sudo engine-setup

初始化立即开始。

[ INFO  ] Stage: Initializing
[ INFO  ] Stage: Environment setup
          Configuration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf

配置部署 oVirt Engine 所需的关键选项。

          --== PRODUCT OPTIONS ==--      
          Configure Cinderlib integration (Currently in tech preview) (Yes, No) [No]:Yes
          Configure Engine on this host (Yes, No) [Yes]:Yes

          Configuring ovirt-provider-ovn also sets the Default cluster's default network provider to ovirt-provider-ovn.
          Non-Default clusters may be configured with an OVN after installation.
          Configure ovirt-provider-ovn (Yes, No) [Yes]:<Enter>
          Configure WebSocket Proxy on this host (Yes, No) [Yes]:<Enter>

          * Please note * : Data Warehouse is required for the engine.
          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]:<Enter>

          * Please note * : Keycloak is now deprecating AAA/JDBC authentication module.
          It is highly recommended to install Keycloak based authentication.
          Configure Keycloak on this host (Yes, No) [Yes]:<Enter>
          Configure VM Console Proxy on this host (Yes, No) [Yes]:<Enter>
          Configure Grafana on this host (Yes, No) [Yes]:<Enter>

它将检查是否有可用的更新。

          Engine admin password:<Set-New-Password>
          Confirm engine admin password:<Confirm-New-Password>
          Application mode (Virt, Gluster, Both) [Both]:<Enter>
          Use Engine admin password as initial keycloak admin password (Yes, No) [Yes]:<Enter>

通过剩余选项的设置值完成。

 --== STORAGE CONFIGURATION ==--

          Default SAN wipe after delete (Yes, No) [No]:<Enter>
  --== PKI CONFIGURATION ==--

          Organization name for certificate [mylab.io]:<Enter>

 --== APACHE CONFIGURATION ==--

          Setup can configure the default page of the web server to present the application home page. This may conflict with existing applications.
          Do you wish to set the application as the default page of the web server? (Yes, No) [Yes]:<Enter>

 --== SYSTEM CONFIGURATION ==--


          --== MISC CONFIGURATION ==--

5. 配置firewalld

您可以安装并激活firewalld以确保您的服务安全。

sudo dnf -y install firewalld
sudo systemctl enable --now firewalld

复制定义了 oVirt Engine 所需端口的 xml 文件。

sudo cp /etc/ovirt-engine/firewalld/* /etc/firewalld/services

重新加载firewalld规则。

sudo firewall-cmd --reload

在firewalld 中允许其他oVirt 服务。

for service in ovn-central-firewall-service ovirt-provider-ovn ovirt-http \
  ovirt-https ovirt-vmconsole-proxy  ovirt-websocket-proxy \
  ovirt-fence-kdump-listener ovirt-imageio-proxy ovirt-postgres; do
sudo firewall-cmd --permanent --add-service $service;
done

重新加载并确认它们是否已添加到允许列表中。

sudo firewall-cmd --reload
sudo firewall-cmd --list-all

6. 访问oVirt引擎Web界面

用于设置主机名的 FQDN 值应在您的 DNS 服务器中具有 A 记录。或者，在本地工作站 /etc/hosts 文件中创建一条记录。

IP FQDN

要在网络浏览器上访问 oVirt Engine，请使用https://manager-fqdn/ovirt-engine。忽略 SSL 证书风险警告。

您可以在以下 URL 获取证书颁发机构的证书。将替换为您在安装过程中提供的 FQDN。

http://<manager-fqdn>/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA

请参阅在浏览器上配置 oVirt/RHEV Manager 证书安全性

要访问管理面板，请使用“门户”下的“管理门户”

使用创建的管理员用户帐户登录。

用户名：admin@ovirt
密码：使用您在安装过程中指定的密码。

您可以添加备用主机名或 IP 地址以访问管理门户。

$ sudo vim /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf
SSO_ALTERNATE_ENGINE_FQDNS="_alias1.example.com alias2.example.com_"

备用主机名列表需要用空格分隔。您还可以将引擎的 IP 地址添加到列表中，但不建议使用 IP 地址而不是 DNS 可解析的主机名。

要添加计算节点，请使用：

在 CentOS Stream 9/Rocky 9 上安装 oVirt 计算节点

7. 访问 Grafana 仪表板

Grafana 网络仪表板位于 https://manager-fqdn/ovirt-engine-grafana/

使用admin用户和您在安装过程中指定的密码登录。
