Missing PHP Extensions

[Haniver]

I'm trying to install Magento on a VPS running CentOS 7. When I do the readiness check, the following four PHP extensions are missing: xsl, intl, mbstring and zip.

On phpInfo I can see xsl and zip under "Authors", but there's nowhere to find intl and mbstring.

How do I know whether dependencies are not installed or only disabled? How do I install them? How do I enable them?

Thank you.

Hello Haniver,

I have already face that problem. you have to manually install all the extension. Several developers have the same problem so I have written a blog about the complete installation process.  It's quite complex to write here you can catch detail here.
