Can anyone please give me tips on configuring Pure-FTPd? The thing I need at this stage is just to make a dedicated file hosting from my low-end VPS to relieve my existing project on a shared hosting. For this, I gather, I need to install (1) nginx (2) pure-ftpd and configure it to give write acess to some user to the root directory of nginx. (1) I achieve by just doing 'yum install nginx' on CentOS. (2) installs the similar way, but whatever I do, I just can't log in with ftp. I guess I need to configure virtual users also, so that I won't have to make a separate unix user for each ftp user that I might need, and keep them ftp users in a separate ftp config file.
