I have successfully installed Centmin to my Centos 6.8 x64 VPS. And now I ran into awkward situation: - There were quite many advices that I should not run Nodejs as root - Centmin main user is nginx and I really don't want to grant /bin/bash to nginx. - I create another user named "manhpt". Can I run any Nodejs App as manhpt (all files and folder within app webroot will be chown to manhpt:manhpt)? After centmin installation, I got "/home/usertmp_donotdelete" (look like a swap file) and "/home/mysqltmp"... Can I delete them?
