We have precompiled packages for CentOS 6, CentOS 7 and Fedora 21 (unfortunately without PF_RING support).

- CentOS 7: ```yum install -y epel-release```

Enable ntop repo (need for PF_RING kernel module and library): ```vim /etc/yum.repos.d/ntop.repo```

Repo file (it's nightbuild version. Stable did not work correctly and haven't headers for ZC version):
```bash
[ntop]
name=ntop packages
baseurl=http://www.nmon.net/centos/$releasever/$basearch/
