带有 Firefox 35.0.1 的 Selenium 2.45 仅在生产中不起作用

Question

我正在使用 Selenium 2.45 和 Firefox 35.0.1 无头浏览器。在开发和测试环境中一切都很好，但在生产中，我遇到了错误。

Driver info: driver.version: FirefoxDriver
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows: 
Xlib:  extension "RANDR" missing on display ":1".

See the manual page for dbus-uuidgen to correct this issue.

Build info: version: '2.45.0', revision: '5017cb8e7ca8e37638dc3091b2440b90a1d8686f', time: '2015-02-27 09:10:26'
System info: host: 'prod', ip: '127.0.0.1', os.name: 'Linux', os.arch: 'amd64', os.version: '2.6.32-431.1.2.0.1.el6.x86_64', java.version: '1.7.0_65'

生产环境：

1) 已下载 firefox-35.0.1

[prod@prod ~]$ ls /usr/local/
bin  etc  firefox   firefox-35.0.1.tar.bz2  games  include  lib  lib64  libexec  sbin  share  src

2) 软链接到 /usr/bin/firefox

[prod@prod ~]$ ll /usr/bin/firefox 
lrwxrwxrwx 1 root root 26 Jun 11 15:59 /usr/bin/firefox -> /usr/local/firefox/firefox
[prod@prod ~]$ 

3) 冉Xvfb

[prod@prod ~]$ ps ax |grep Xvfb
15425 ?        S      0:00 sudo Xvfb +extension RANDR :1 -screen 0 1024x768x24
15426 ?        S      0:00 Xvfb +extension RANDR :1 -screen 0 1024x768x24
23102 pts/6    S+     0:00 grep Xvfb

测试环境：

[root@vc-stage ~]# ll /usr/bin/firefox 
lrwxrwxrwx 1 root root 26 May 24 21:32 /usr/bin/firefox -> /usr/local/firefox/firefox
[root@stage ~]# 
[root@stage ~]# ls /usr/local/
bin  etc  firefox  firefox-35.0.1.tar.bz2  games  include  lib  lib64  libexec  sbin  share  src
[root@stage ~]# 
[root@stage ~]# ps ax | grep Xvfb
 3899 pts/5    S+     0:00 grep Xvfb
27393 ?        S      0:01 Xvfb +extension RANDR :1 -screen 0 1024x768x24
[root@stage ~]# 

test 和 prod 之间的唯一区别是；在测试中，我从 root 用户运行所有内容。在 prod 中，我由 sudo 用户运行。

更新：错误消息消失了，没有任何更改，Duh。现在，它根本不创建 Firefox 驱动程序。

一切都很好。生产中缺少 1 个包 - “dbus”。安装和配置软件包后，一切正常。
