I am subscribed to the CF-Linux list hosted at houseoffusion.com and I see a lot of people having problems installing CFMX on linux. Especially on Redhat 7.3. Macromedia has said that there were problems related to Java in RedHat 7.3 and urged customers to use RedHat 7.2.
Today I installed CFMX on RedHat 8.0 after running redhat's up2date utility (similar to windows update), and everything went fine. I wasn't sure if it would work because of what I have heard, so I figured I would post some positive results in case anyone is wondering. Keep in mind that I haven't tested all the features of CFMX like verity, etc.
