How to Install Glances on Legacy RHEL and CentOS (5, 6, 7)

This is a legacy page. If you are running a supported platform, use one of the newer guides instead:

Keep using this page only if you are dealing with legacy RHEL or CentOS 5, 6, or 7 estates that cannot yet be migrated.

Important warning

RHEL and CentOS 5, 6, and 7 are legacy operating systems. They are not where you should be deploying new monitoring tooling unless you are tied to a migration or support constraint. Treat this page as a compatibility reference, not the preferred installation path.

Legacy RHEL 5 and 6 workflow

On very old systems, Glances is typically installed through older Python package flows rather than the modern DNF/EPEL pattern used on current RHEL-family systems.

sudo -i
sudo yum-config-manager --enable rhel-server-rhscl-6-rpms
sudo yum install rh-python36 -y
sudo scl enable rh-python36 bash
sudo pip install --upgrade pip
sudo pip install bottle
sudo pip install glances

Legacy RHEL 7 and CentOS 7 workflow

RHEL 7-era systems often use Software Collections and older package combinations:

sudo yum-config-manager --enable rhel-server-rhscl-7-rpms
sudo yum install rh-python36 -y
sudo yum install rh-python36-python-pip -y
sudo scl enable rh-python36 bash
curl -L https://bit.ly/glances | /bin/bash

Starting Glances

Terminal mode

glances

Web interface

glances -w -t 5

Browse to:

http://<your_server_ip>:61208

Troubleshooting on older systems

If glances is not found, confirm the correct Python environment is active.
If the web interface does not load, verify the process is running and the host firewall is not blocking port 61208.
If packaging is inconsistent, it is often a sign the underlying operating system is too old for a clean install path.

Use the modern guides when possible

This page stays focused on old RHEL and CentOS releases so it does not compete with the current enterprise Linux guides.
