Your 64-bit executable has 32 too many bits for your 32-bit operating system. You will need to run it on a 64-bit OS. Bonus information: if things were reversed and this was a 32-bit binary that you were trying to run on a 64-bit OS, it could be done trivially after ensuring that ia32-libs or equivalent was installed. Speaking frankly, though, this is 2016....

The two are often used interchangeably but even two things both named VM or VPS can be quite different on a technical level. In the end, a VM is more of a technical term while VPS is a marketing item.

You don't. But I have very little knowledge about server. and creating a name server are not compatible. Getting DNS right is quite complicated and really a waste of time as you get a large number of providers that do that for you for a few dollars a year.

If your Application is getting hacked, they can use the api to gather all information they want. So if your application is hacked you are lost in any way. Best practice should be to setup the database without a dedicated public ip address. Make sure your database server is not reachable from the web. If you are scared about your application security, you ...

I like to use rsync. You can just rsync to your single backup if your goal is to have a backup if the VPS disappears, but for minimally more hard disk space you can use rsync hardlinked backups. You probably need to have a Linux system to backup to, because while rsync exists for Windows I don't think it would work with hard links.

You can change the async settings for yum repositories by adding async=0 to prevent metadata and packages from being downloaded in parallel. For example, /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS-$releasever - Base mirrorlist=http://mirrorlist.centos.org/... async=0 Alternatively, you should be able to add this to the [main] section of /etc/...

The IP address (I'll call it just one here, but the concept applies equally well with any number of addresses) which is assigned to the VPS is assigned to the ISP where the VPS is running. In forward DNS, you register a domain name, have it pointed at your name servers, and configure those name servers to serve that zone. In reverse DNS, the owner of the ...

You missed one possibly vital argument to rsync: --hard-links. It depends on the distribution, and I guess it's different now than it is in the past, but system directories and/or files (more so than user files) can easily be hard links to others. For example, in the somewhat recent past on Archlinux, /usr/X11R6/bin was a hard-link to /usr/bin. At present, I ...
