问题描述
我正在尝试让Selenium在Linux应用程序服务器上进行一些自动浏览.我被困在Selenium的"Perl录制"发送启动浏览器的请求的时刻，而独立的Selenium服务器抛出错误-超时，等待创建配置文件！".
I am trying to get Selenium to do some automated browsing on a Linux application server. I am stuck at the point where my 'perl recording' from Selenium sends a request to start the browser, and the standalone selenium server throws an error - 'Timed out waiting for profile to be created!'.
通过浏览此错误，我了解到可以通过为安装在linux服务器上的firefox浏览器创建配置文件来解决此问题.但是，当我尝试创建配置文件时，现在出现错误-
I understand from browsing this error, that I could resolve this by creating a profile for the firefox browser I installed on the linux server. However, when I try to create a profile, I now get the error -
当我查找此消息时，发现有SO帖子，建议我可以通过以下方法解决此问题:首先在服务器上安装xvfb，然后在启动Selenium服务器之前设置DISPLAY变量.但是，我不是root用户，想检查xvfb是否可以在用户的主目录中本地安装.
When I look this up, I find SO posts that suggest I could resolve this by installing xvfb first on the server and then setting the DISPLAY variable before starting the selenium server. However, I am not a root user, and wanted to check if xvfb can be installed locally on a user's home directory.
推荐答案
首先需要安装 X窗口系统框架缓冲区x服务器:
yum install xorg-x11-server-Xvfb.x86_64
确保已安装Firefox，然后在某些显示端口(如99)上启动x服务器
make sure you have firefox installed, then start the x server on some display port like 99
Xvfb :99 -ac -screen 0 1280x1024x24 &
通过在代码或bash配置文件中导出DISPLAY =:99，将DISPLAY环境设置为99.
Set the DISPLAY environment to 99 by export DISPLAY=:99 in your code or maybe in bash profile.
