sudo yum -y install firefox Xorg
Seems to me like it's just installing the prerequisites for the virtual frame buffer (Xvfb), which itself is headless.
what's the point installing whole graphical environment and then run headless? all these packages are not needed for xvfb
The command sudo yum -y groupinstall "X Window System" "Desktop" "Fonts" "General Purpose Desktop" doesn't appear to be necessary to get selenium-server to work. In fact, all it did was make my development VM unbootable.
Other than that, this was very helpful. Just skip step 2 when setting up the CentOS box and all is good.
Tried to follow the procedures but step 2 gotta error.
$ sudo yum -y groupinstall "X Window System" "Desktop" "Fonts" "Geberal Purpose Desktop"

Hi - I followed these instructions above, but ran into an issue with Firefox not working due to some library mismatches in RHEL 7.1. After trying several things to no avail, I uninstalled the default firefox package (yum delete firefox) and installed specifically the .i686 package (yum install firefox.i686). Which I know seems counterintuitive, since RHEL is running on the x86_64 architecture, but for some reason, this did it for me.
Just letting other people know this might work, since I spent a good few days dabbling "in the dark".
I skip the step 2 as @shssoichiro suggested, It works fine! Thank you, both!
How is that headless? You install the whole graphical environment!
