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）：

[root@engine178 ~]# engine-setup

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

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。
