部署ovirt-engine服务

安装ovirt-engine软件包后，还需要在管理节点部署ovirt-engine服务，才能使ovirt-engine软件可用。

1. 创建软链接。

   ln -sf /usr/lib64/libpq.so.private13-5.13 /usr/lib64/libpq.so.5

2. 执行部署命令。

   engine-setup --offline

   部署过程中返回如下信息，此外还需要执行一定的操作，请参考如下信息配置。

   返回successfully信息表示成功部署ovirt-engine服务。

3. 验证ovirt-engine是否已经部署成功。
   1. 打开本地PC的“C:\windows\system32\drivers\etc\hosts”文件，添加如下内容。

      节点IP地址    controller

   2. 通过浏览器访问“https://controller/ovirt-engine”，进入oVirt管理前端页面。您也可以在此页面切换语言。
   3. 在oVirt管理前端页面单击“管理门户”进入ovirt-engine登录界面。如果可以进入ovirt-engine登录界面，表示ovirt-engine已经部署成功。

      

   4. 在ovirt-engine登录界面输入登录用户名和密码。密码是安装ovirt-engine如下过程中自行设置的，根据实际情况修改。在本例中用户名为admin，密码为123456。

      

      

      • 本例中主机名是“controller”，Web管理界面URL是“http://controller:80/ovirt-engine”或者“https://controller:443/ovirt-engine”。
      • 如果无法访问URL，需要在ovirt engine节点关闭防火墙。

        systemctl disable firewalld.service
        systemctl stop firewalld.service
