简介

本文档介绍如何在配置工作映像时排除虚拟网络计算(VNC)模块安装故障。

先决条件

要求

Cisco 建议您了解以下主题：

Linux界面
虚拟机环境
工作人员映像

使用的组件

本文档中的信息基于以下软件版本：

CloudCenter版本4.x
CentOS7员工映像

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

背景信息

下载worker_installer.bin文件后，在使用此处提到的命令配置Centos 7工作器映像时，它通常会跳过VNC的交互模块，即使该过程成功完成。

# ./worker_installer.bin centos7 <cloudtype> worker

本文帮助您处理此类情况。

问题

安装失败

在cliqr_modules.log中，可以看到依赖项故障(glib-2.4)。

<noscript> <table="class="msgText">似乎您未启用JavaScript，请与管理员联系。

使用此工作映像可以成功部署应用，但用户无法通过VNC从Cisco Call Manager(CCM)用户界面(UI)访问已部署实例。

启动失败

在/var/log/messages文件中，可以检查VNC是否正确启动。

Sep 20 15:42:58 cliqr-centos6-base-image OSMOSIX: starting vnc server, result: 127

正确安装VNC时，结果代码应为0。

Nov 25 12:18:18 cqjw-58d79d88f OSMOSIX: starting vnc server, result: 0

解决方案

VNC安装依赖于GNOME库。因此，解决方法是，以管理员身份执行此步骤。

# export gui_enabled=true

这可解决VNC安装错误。

epel-release存储库是安装交互式模块的前提条件。执行此命令以安装回购。

yum -y install epel-release

成功完成上述步骤后，请重复工作映像配置。

 ./worker_installer.bin centos7 <cloudtype> worker

由于安装了其他模块，因此只安装VNC和交互模块。

安装VNC后，它应位于文件/etc/cliqr_modules.conf中

[cliqruser@cqjw-58d79d88f etc]$ cat cliqr_modules.conf
sysupdate
worker
ntp
docker
vnc
interactive
[cliqruser@cqjw-58d79d88f etc]$

要使vnc工作，也需要安装X窗口。

[root@cqjw-58d79d88f ~]# cat /var/log/messages | grep vnc

[root@cqjw-58d79d88f ~]#

为vnc正确配置工作映像后，可以创建VM的模板，以用作已正确安装并运行vnc的工作设备。另请参阅。
