There are some differences on setting up RRDReST on CentOS 8, Almalinux 9 vs CentOS 7<\/p>\n\n\n\n
If you are setting this up to use with LibreNMS and Grafana, check out the rest of the this article. https:\/\/www.incredigeek.com\/home\/setting-up-grafana-on-librenms\/<\/a><\/p>\n\n\n\n <\/p>\n\n\n\n All the docker commands have been swapped out for podman.<\/p>\n\n\n\n Podman is default on CentOS 8 and later and is, for the most part, a drop in replacement for Docker.<\/p>\n\n\n\n Create a Podman \/ Docker network to use. We’ll use this to assign a static IP address to the container. We’ll call the network rrdnet, and we’ll use the 10.89.2.0\/24 range.<\/p>\n\n\n\n Create a docker compose file<\/p>\n\n\n\n Add the following<\/p>\n\n\n\n Change the TZ to your time zone. If you have issues with the graphs, most likely something is off with the time zone between this container and Grafana\/LibreNMS server<\/p>\n\n\n\n Note that the :Z is needed for SELinux to allow RRDReST to access the sub folders. AKA. the rrd files.<\/p>\n\n\n\n The container should have a 10.89.2.2 IP address. You can take all the networking sections out, and the container will receive DHCP. The problem is that the IP can change, breaking our graphs in Grafana.<\/p>\n\n\n\n Save the file. Then start and setup the container with<\/p>\n\n\n\n You will need your docker container IP address to setup the connection in Grafana. If you used the above docker-compose config, then it should be 10.89.2.2.<\/em><\/p>\n\n\n\n The “restart: always” option does not appear to work on systems with podman. We can create a systemd service instead.<\/p>\n\n\n\n Use the following command to automatically create a systemd file.<\/p>\n\n\n\n Copy the contents to a new file in \/etc\/systemd\/system\/<\/p>\n\n\n\n If you end up deleting the rrdrest container, you’ll need to update the systemd file again. You may need also need to run “systemctl daemon-reload”<\/em><\/p>\n\n\n\n Enable the new service with<\/p>\n\n\n\n <\/p>\n\n\n\n Congratulations. RRDReST is now setup and running.<\/p>\n\n\n\n You can verify it’s running by checking with Podman \/ Docker.<\/p>\n\n\n\n You can also ping it<\/p>\n\n\n\n There are some differences on setting up RRDReST on CentOS 8, Almalinux 9 vs CentOS 7 If you are setting this up to use with LibreNMS and Grafana, check out the rest of the this article. https:\/\/www.incredigeek.com\/home\/setting-up-grafana-on-librenms\/ Installing RRDReST All … Continue reading Installing RRDReST<\/h1>\n\n\n\n
