I have a CentOS 6.7 system that is behind a firewall with no outbound. It is a vanilla, working rig.

I need to install: - jemalloc - redis

I have the rpm for jemalloc on the system locally, but it won't install complaining about requiring glibc

[root@localhost tmp]# rpm -ivh jemalloc-3.6.0-8.el7.centos.x86_64.rpm
error: Failed dependencies:
        libc.so.6(GLIBC_2.14)(64bit) is needed by jemalloc-3.6.0-8.el7.centos.x86_64
[root@localhost tmp]#

But that makes no sense to me, as glibc is in the local rpm repository, it appears to me:

[root@localhost tmp]# rpm -qa|grep glibc
[root@localhost tmp]# yum install glibc
Loaded plugins: changelog, fastestmirror, security
Setting up Install Process
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
[root@localhost tmp]

What am I missing?

  • jemalloc requires glibc 2.14 and you have version 2.12 installed.

  • @n8te Thanks, I see what you refer to. But for centos 6.7, there doesn't seem to be glibc 2.14 Dec 15, 2016 at 5:30
  • Have a look at this CentOS forum discussion. It's not a solution to your problem but worth reading as they strongly advise against trying to install glibc 2.14 on CentOS 6.

  • @n8te Thanks. I get it now. See answer I posted below. (I referred to a running centos 6.x system to see what versions of things were there) Dec 15, 2016 at 5:38

1 Answer 1


Answer: Use jemalloc 3.6.0-1 on Centos 6.x, do not use (or try to use) jemalloc 3.6.0-8, as that is for Centos 7....

  • +1 Glad to see you found an alternative solution.
