2. 运行 engine-setup 命令来配置 websocket 代理。

   # engine-setup

   Copy to Clipboard Toggle word wrap

   注意

   如果 rhevm 软件包也被安装，则在被询问是否在这个主机上配置引擎时选择 No。
3. 按 Enter 来允许 engine-setup 在机器上配置一个 websocket 代理服务器。

   Configure WebSocket Proxy on this machine? (Yes, No) [Yes]:

4. 点 Enter 接受自动检测到的主机名（请注意，如果您使用的主机是虚拟机，自动检测到的主机名可能不正确）；或输入一个不同的主机名后点 Enter：

   Host fully qualified DNS name of this server [host.example.com]:

5. 按 Enter 允许 engine-setup 配置防火墙并打开外部通讯所需的端口。如果不允许 engine-setup 修改您的防火墙配置，则需要在以后手工打开所需的端口。

   Setup can automatically configure the firewall on this system.
   Note: automatic configuration of the firewall may overwrite current settings.
   Do you want Setup to configure the firewall? (Yes, No) [Yes]:

6. 输入 Manager 所在机器的完全限定 DNS 名并点 Enter：

   Host fully qualified DNS name of the engine server []: engine_host.example.com

   Copy to Clipboard Toggle word wrap
7. 按 Enter 允许 engine-setup 在 Manager 的机器上执行操作，或按 2 来手工执行这些任务。

   Setup will need to do some actions on the remote engine server. Either automatically, using ssh as root to access it, or you will be prompted to manually perform each such action.
   Please choose one of the following:
   1 - Access remote engine server using ssh as root
   2 - Perform each action manually, use files to copy content around
   (1, 2) [1]:

   1. 按 Enter 接受默认的 SSH 端口号，或输入 Manager 机器的端口号。

      ssh port on remote engine server [22]:

   2. 输入登录到 Manager 机器的 root 密码并按 Enter。

      root password on remote engine server engine_host.example.com:

8. 选择是否复查 iptables 规则。

   Generated iptables rules are different from current ones.
   Do you want to review them? (Yes, No) [No]:

   如何配置 Manager 机器来使用设置的 websocket 代理的信息会被显示。

   Manual actions are required on the engine host
   in order to enroll certs for this host and configure the engine about it.
            
   Please execute this command on the engine host: 
      engine-config -s WebSocketProxy=host.example.com:6100
   and than restart the engine service to make it effective

10. 登录到 Manager 的机器，运行以下命令：

    # engine-config -s WebSocketProxy=host.example.com:6100
    # systemctl restart ovirt-engine.service
