title: command to install PCRE 7.2
body: <p>My software works on shared hosting, but problems with login on private virtual. Developer says its a PCRE issue. Host says I have to do it myself. Root makes me nervous.</p>
  
  <p>I think I can install yum, after which, what command do I run?</p>
  
  <p>ie. "yum install PKGNAME"</p>
  
  <p>I found this references on <a href="http://mirror.centos.org/centos/5/os/i386/CentOS/" rel="nofollow">http://mirror.centos.org/centos/5/os/i386/CentOS/</a></p>
  
  <p>pcre-6.6-3.el5 1.7.i386 but presumed that was incorrect.</p>
  
  <p>Thank you.</p>
