[syslog-ng] Install Syslog-ng OSE into Virtual Machine - RHEL OS

Thu Oct 17 19:16:58 UTC 2019

Another question:

     Who to install the syslog-ng OSE into a RHEL 7(virtual machine), because this machine have no access to internet.

So how to do this steps of manual, without internet:

2. The Extra Packages for Enterprise Linux (EPEL)<https://fedoraproject.org/wiki/EPEL> repository contains many useful packages, which are not included in RHEL. A few dependencies of syslog-ng are available this repo. You can enable it by downloading and installing an RPM package:

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh epel-release-latest-7.noarch.rpm

3. Add the repo containing the latest unofficial build of syslog-ng. By the time of writing it is syslog-ng 3.24 and it is available on the Copr build service. Download the repo file to /etc/yum.repos.d/, so you can install and enable syslog-ng:

cd /etc/yum.repos.d/
wget https://copr.fedorainfracloud.org/coprs/czanik/syslog-ng324/repo/epel-7/czanik-syslog-ng324-epel-7.repo
yum install syslog-ng
systemctl enable syslog-ng
systemctl start syslog-ng

Add any further sub-packages you need.

4. It is not strictly required, but you can avoid some confusion, if you also delete rsyslog at the same time:

yum erase rsyslog

 Tks,

RHEL and derivatives uses rsyslog by default, so if you plan to use syslog-ng instead, you should remove rsyslog first. Other configs are highly depends on your usecase (like adjust kernel parameters for heavy UDP traffic and so on). Also quite generic people are facing with issues with selinux and firewalld but obviously there are solutions for any of these (other than turning off these services :))

Good aftenoon !

    I will install the syslog-ng OSE into a virtual machine with RHEL 7.

    Is there anything I should worry about when installing on a virtual machine?

    Is there something to configurated on OS, before or after the install syslog-ng?

Tks,
