虽然说Oracle已经停止了VDI的开发，之后支持服务业很快停止了。但是，作为经典的桌面虚拟化产品，还是值得研究一番。虽然Oracle VDI的文档已经写的很详细了，但是在实际操作过程中，还是会遇到很多问题。最近，终于鼓起勇气，在VDI即将消失之前，把安装过程记录一下。

安装环境和前期条件

• OS： Oralce Linux 6 update5 x86-64
• Oracle VDI 3.5.2
• SELinux 已经禁用
• 防火墙(iptables)已经关闭

安装步骤

配置Yum源

首先需要保证能上外网，并能够访问public-yum.oracle.com。

开始配置Yum环境，把public-yum-ol6.repo下载到/etc/yum.repos.d目录，并编辑内容如下：

[ol6_u5_base]
name=Oracle Linux $releasever Update 5 installation media copy ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/5/base/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1 ###开启[ol6_addons]
name=Oracle Linux $releasever Add ons ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/addons/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1 ###开启[ol6_UEK_base]
name=Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/base/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1 ###开启[ol6_gdm_multiseat]
name=Oracle Linux 6 GDM Multiseat ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/gdm_multiseat/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1 ###开启

配置/etc/yum.conf，在文件末尾加入如下内容：

# 开启多版本库支持
protected_multilib=0

代理服务器配置

如果使用代理服务器上外网的话，还需要做如下设置。

设置wget的代理

在/etc/wgetrc修改为如下内容：

# You can set the default proxies for Wget to use for http, https, and ftp.
# They will override the value in the environment.
https_proxy = http://my-proxy.example.com:80/
http_proxy = http://my-proxy.example.com:80/
ftp_proxy = http://my-proxy.example.com:80/

设置Yum的代理

在/etc/yum.conf末尾加入如下内容：

proxy=http://my-proxy.example.com:80/

预先安装可能导致出错的包

sssd-client可能在安装过程中出现错误，先手动安装一下。

[root@vdi ~]# yum install sssd-client

在64为系统中会安装libXfont.x86_64，但是VDI需要32位的版本 - libXfont.i686，这也可能出现问题，先手动安装一下。

[root@vdi]# yum install -y libXfont.i686

安装过程中会需要安装pam.i686，在64位环境下，已经安装了pam.x86-64。同时安装32位和64位的包可能会产生如下错误：

Transaction Check Error:file /etc/security/limits.conf from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/Linux-PAM_SAG.txt from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/html/sag-pam_cracklib.html from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/html/sag-pam_limits.html from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/html/sag-pam_userdb.html from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/txts/README.pam_cracklib from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/doc/pam-1.1.1/txts/README.pam_userdb from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man5/limits.conf.5.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man5/namespace.conf.5.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/faillock.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_cracklib.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_env.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_faillock.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_lastlog.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_tty_audit.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64file /usr/share/man/man8/pam_userdb.8.gz from install of pam-1.1.1-20.el6.i686 conflicts with file from package pam-1.1.1-17.el6.x86_64

这个pam包中的一个既存的bug，通过下面的方法解决：

[root@vdi ~]# yum install -y yum-downloadonly
[root@vdi ~]# yum install pam.i686 -y --downloadonly --downloaddir=/tmp
[root@vdi ~]# cd /tmp
[root@vdi tmp]# rpm -ivh --force --nodeps pam-1.1.1-20.el6.i686.rpm
[root@vdi tmp]# yum reinstall pam.i686

题外话，使用yum安装软件，老是会遇到这种提示：

Existing lock /var/run/yum.pid: another copy is running as pid 3053.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit

只要把/etc/yum/pluginconf.d/refresh-packagekit.conf改为如下就OK了:

enabled=0

开始安装 vda

由于VDI安装脚本调用了curl来检查联网状态，所以如果是通过代理服务器上外网的，还需要在执行安装命令之前为curl设置如下环境变量以使用代理：

[root@vdi vda_3.5.2_linux]# export http_proxy=http://my-proxy.example.com:80/
[root@vdi vda_3.5.2_linux]# export https_proxy=$http_proxy
[root@vdi vda_3.5.2_linux]# export HTTP_PROXY=$http_proxy
[root@vdi vda_3.5.2_linux]# export HTTPS_PROXY=$http_proxy

现在可以开始安装了，安装过程中Yum会自动连外网下载依赖的包，过程会很漫长：

[root@vdi vda_3.5.2_linux]# unzip p21441793_350_Linux-x86-64.zip
[root@vdi vda_3.5.2_linux]# cd vda_3.5.2_linux

安装 VirtualBox

接下来，需要安装 VirtualBox。需要连外网通过wget来下载VirtualBox的安装文件。

[root@vdi vda_3.5.2_linux]# unzip vbox_4.2.zip

至此，Oracle VDI的安装已经完成，接下来就可以登录到 Oracle VDI Manager开始配置了:

http://vdi.example.com:1800

由于接下来的配置工作都是基于图形界面完成的，这里就不再赘述，可以查看这篇文档来进行。
