Centos8.2安装oVirt-engine V4.4.1

oVirt-engine既可以以虚机的形式部署在ovirt-node上,也可以部署在一台独立的服务器上,本文以oVirt4.4.1版本的engine在Centos8.2上的部署为例展示下独立部署的过程。

首先安装Centos8.2,可以安装minimal版本的,可以将此系统安装在虚拟机中,安装过程略。

安装完Centos8.2系统后,以root用户进入系统,设置系统主机名,并在/etc/hosts中添加解析。

配置ovirt4.4的yum源并启用需要的模块

# dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
# dnf module -y enable javapackages-tools
# dnf module -y enable pki-deps
# dnf module -y enable postgresql:12

升级系统软件包

dnf -y update

安装ovirt-engine软件包

dnf -y install ovirt-engine

执行engine-setup命令初始化配置ovirt-engine,过程如下(基本都采用默认选项即可):

setup成功后,到/etc/ovirt-engine/engine.conf.d这个目录下,

新建“99-custom-sso-setup.conf”这个文件,

文件内容为(此处的ip地址根据你的实际环境填写):

SSO_ALTERNATE_ENGINE_FQDNS="192.168.8.178"   

重启engine服务,

systemctl restart ovirt-engine   

然后可以在浏览器里通过ip访问了:

https://192.168.8.178

Centos8.2安装oVirt-engine V4.4.1

之后就可以添加主机了。

因hosted-engine部署经常会碰到一些问题,建议可将ovirt-engine独立部署,主机建议通过ovirt-node的iso镜像安装(比较简单),安装完主机,就可以到ovirt-engine的管理台添加主机和存储了。

  1. 您好 我使用iso镜像做的Node节点,用xftp上传一个4G得镜像,速度从80M/S一直下降到30M/S才稳定,而使用centos镜像装就稳定80M/S,希望版本看到回答一下,这个问题影响到存储啊(测了好几遍了)

    • 首先我先确定一下问题情况:
      1、使用xftp上传镜像,是上传的iso镜像吗,上传到什么地方了?
      2、使用centos镜像装是指通过在centos上使用yum安装host的方式吗?
      3、这两种不同方式所对应的服务器硬件环境一致吗?

    • 1、对,上传到root目录下(其他目录也一样),这个上传镜像不是别的意思,就是传个大点的文件,测试一下传输速度(本地磁盘最大的文件就是镜像了“捂脸”)
      2、不是,我指的是重做系统,ovirt-node不是官方提供最小化的镜像安装node节点嘛,然后做完,测试nfs上传速度就很慢,您可以试下, 然后我使用centos官网下载的镜像,装完系统以后,在测试上传就很稳定,
      3、环境一样,专门在一样的环境测了一下,确实是这样。如果方便 的话我不清楚微信群里哪个是您,我可以给您发下截图

    • 2、不是测试nfs,是ftp,扣错了

    • node的版本发一下

  2. 1、对,上传到root目录下(其他目录也一样),这个上传镜像不是别的意思,就是传个大点的文件,测试一下传输速度(本地磁盘最大的文件就是镜像了“捂脸”)

    • 第二点,测试nfs上传是?再具体说下

      评论可以附图片的。

  3. 说错了,是测试ftp上传
    这是centos官网的镜像安装的系统测试结果为80M/S

    这是使用ovirt下载的iso镜像安装的系统测试结果为30M/s(从80M/s逐步下降到30M/s)

  4. dnf module -y enable javapackages-tools 这里系统提示没有这个模块
    缺少的组或模块 : javapackages-tools

    • 解决了。安装的时候不要选择开发工具,就选择最小化安装。基本上没有问题了。
