How to get past MongoDB/PCRE “symbol lookup error” when upgrading from MongoDB 1.8 to 2.4

If you get that /usr/bin/mongod: symbol lookup error: /usr/bin/mongod: undefined symbol: _ZN7pcrecpp2RE4InitEPKcPKNS_10RE_OptionsE then you should install pcre and pcre-devel from the repository like this: sudo yum install pcre pcre-devel Details on how I discovered...

Assuming a RHEL or CentOS-like system, this is a bug, detailed in: Red Hat 995097. The fix that I have in place is to use the oddjobd process to create directories, rather than the legacy pam_mkhomedir. So if you don't already have it, yum install oddjob-mkhomedir. From there, you can...

I guess that you're just facing the problem of unsatisfied dependencies.
