Have just taken over control of a CentOS 6.4 web server with Apache.

My question is, to update the server software, is it a case of just using yum update and then yum upgrade?

Server has been neglected until now so need to install new security patches etc, but I don't (obviously) want to risk losing clients' documents / sites.

  • FYI, 6.4 isn't what I would call a neglected server 8-). – slm Apr 24 '14 at 13:11
  • @slm It's more the security side than the actual version itself – Wildcard27 Apr 24 '14 at 13:23
  • Is there (a) MySQL or PostGres database installed? If MySQL shows up as installed and being updated, there is some pre-update and post-update work you should do as well. I don't know the steps for PostGres though. – CGCampbell Apr 24 '14 at 15:51

Yes just running yum update and yum upgrade is how you would approach this. You'll need to pay special attention if there are any applications that require PHP, Perl, etc. that are called through a module within Apache.

You can also do a yum check-update to get a sense of how much will be touched prior to running the actual update.

  • Is the update likely to affect PHP and PERL? I thought I would have to update them separately? I only really want to install the security update. The server has been hacked and need to do what I can to prevent it happening again – Wildcard27 Apr 24 '14 at 13:21
  • You can list what's going to be updated and selectively upgrade packages. See man yum. – Chipster Apr 24 '14 at 13:49
  • @matt1985 - it might if you don't specify what to update: yum update apache, for example. – slm Apr 24 '14 at 14:34
