How to Install Prometheus in Linux Ubuntu 18.04

Posted on


This article will show how to install prometheus in Linux Ubuntu 18.04 in several steps. There are few steps for having the installation of prometheus runs in Linux Ubuntu 18.04 normally. According to the main official website of Prometheus in this link, Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud. Since its inception in 2012, many companies and organizations have adopted Prometheus. The project has a very active developer and user community. It is now a standalone open source project and maintained independently of any company. To emphasize this, and to clarify the project’s governance structure, Prometheus joined the Cloud Native Computing Foundation in 2016 as the second hosted project, after Kubernetes. In order to put it simple, Prometheus is an open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.


The easiest way is using the regular ‘apt’ tool exist in Linux Ubuntu distribution. First of all, search the package by executing the following command :

Starting the Prometheus service

After successfully install prometheus, start the service.  Execute the following command  as in the following output below :

root@hostname:~# systemctl start prometheus

Don’t forget to check the status of the prometheus service. Type the command ‘systemctl status prometheus’ to be able to check the status of the service as follows :

root@hostname:~# systemctl status prometheus
● prometheus.service - Monitoring system and time series database

Finally, in order for prometheus service is automatically start and running every time the machine is rebooting, do the following command :

root@hostname:~# systemctl enable prometheus
Synchronizing state of prometheus.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable prometheus

If all the above steps are successfully executed, all of the overall process for installing Prometheus has done.
