how do a clean install of alfresco on a centos x64 bit box. i can't find any post that match this. and there doesnt seem to be any documentation out there. can someone please help.
If you are ok with using the linux-installer its just a matter of making the bin file executable (chmod +x), and then run it as root (or with sudo) ./installationfile.bin
If you do not want to run alfresco as root (which you do not want on a production system) change the ownership of the /opt/[installationdir] to another user afterwords.
Pretty straight forward.
You can always install all modules separatly as well, there are a lot of instructions out there.
