排除VNC模組安裝故障

簡介

本文描述如何在配置工作器映像時排除虛擬網路計算(VNC)模組安裝故障。

必要條件

需求

思科建議您瞭解以下主題：

• Linux介面
• 虛擬機器環境
• 工作人員影象

採用元件

本檔案中的資訊是根據以下軟體版本：

• CloudCenter 4.x版
• CentOS7工作人員映像

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

背景資訊

下載worker_installer.bin 檔案後，當您使用此處提到的命令配置Centos 7 worker映像時，它通常會跳過VNC的互動式模組，即使過程成功完成。

# ./worker_installer.bin centos7 <cloudtype> worker

本文可幫助您處理此類情況。

問題

安裝失敗

在cliqr_modules.log中，可以看到依賴關係失敗(glib-2.4)。

<noscript> <table=" class="msgText"> 如果您未啟用JavaScript，請與管理員聯絡。

使用此工作映像可以成功部署應用程式，但使用者無法從Cisco Call Manager(CCM)使用者介面(UI)通過VNC訪問已部署的例項。

啟動失敗

在/var/log/messages檔案中，可以檢查VNC是否正確啟動。

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

正確安裝VNC後，應該會看到0作為結果代碼。

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

解決方案

VNC安裝依賴於GNOME庫。因此作為解決方法，請以管理員身份執行此步驟。

# export gui_enabled=true

這將解決VNC安裝錯誤。

解除安裝版本儲存庫是安裝互動式模組的前提條件。執行此命令以安裝回購。

yum -y install epel-release

成功完成上述步驟後，請重複工作映像配置。

 ./worker_installer.bin centos7 <cloudtype> worker

由於安裝了其他模組，因此只安裝了VNC和互動式模組。

安裝VNC後，它應位於檔案/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正常工作，還需要安裝X Windows。

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

[root@cqjw-58d79d88f ~]#

在為vnc正確配置工作映像後，例如，在cloudtype vmware的情況下，可以建立虛擬機器模板，以作為vnc正確安裝並正常工作的工作映像。另請參閱。

 通過上面部署工作器，可以使用vnc連線到工作器，如下圖所示。
