WeeWX: Installation on Redhat-based systems

This is a guide to installing WeeWX from an RPM package on systems such as Redhat, CentOS or Fedora.

This requires a version of the operating system based on Redhat 8 or newer.

Compatible Operating System Versions

WeeWX v5 requires python v3.7, which is only available on operating systems based on redhat-8 or later. No packages for python2-only operating systems will be provided.

It is recommended that users of older operating systems continue to use WeeWX v4 until you can update your operating system to a more current version supporting python v3.7 at a minimum.

Install pre-requisites

Unfortunately, not everything that WeeWX uses is included in the standard Redhat repositories. You will need to enable their respective EPEL ("Extra Packages for Enterprise Linux") repositories, then install some prerequisites manually.

Add the EPEL repo and install prerequisites:

sudo yum install epel-release
sudo yum install python3-cheetah

Configure yum

Tell yum or dnf where to find the WeeWX releases.

This only has to be done once - the first time you install WeeWX.

Tell your system to trust weewx.com:

sudo rpm --import https://weewx.com/keys.html

Enable the WeeWX repo:

curl -s https://weewx.com/yum/weewx-el8.repo | sudo tee /etc/yum.repos.d/weewx.repo

Install WeeWX

Install WeeWX using yum or dnf. When you are done, WeeWX will be running the Simulator in the background as a daemon.

sudo yum install weewx

Status

Look in the system log for messages from WeeWX.

sudo tail -f /var/log/messages

Verify

After 5 minutes, open the station web page in a web browser. You should see generic station information and data. If your hardware supports hardware archiving, then how long you wait will depend on the archive interval set in your hardware.

Configure

The default installation uses Simulator as the station_type. To use real hardware, stop WeeWX, change to the actual station type and station parameters, delete the simulation data, then restart WeeWX:

sudo /etc/init.d/weewx stop
sudo wee_config --reconfigure
sudo rm /var/lib/weewx/weewx.sdb
sudo /etc/init.d/weewx start

Start/Stop

To start/stop WeeWX:

sudo /etc/init.d/weewx start
sudo /etc/init.d/weewx stop

Customize

To enable uploads such as Weather Underground or to customize reports, modify the configuration file /etc/weewx/weewx.conf. See the User Guide and Customization Guide for details.

WeeWX must be restarted for configuration file changes to take effect.

Uninstall

To uninstall WeeWX, removing configuration files but retaining data:

sudo yum remove weewx

To remove data:

sudo rm -r /var/lib/weewx
sudo rm -r /var/www/html/weewx

Layout

The installation will result in the following layout:


                    executable: /usr/bin/weewxd
            configuration file: /etc/weewx/weewx.conf
           skins and templates: /etc/weewx/skins
              sqlite databases: /var/lib/weewx/
generated web pages and images: /var/www/html/weewx/
                 documentation: /usr/share/doc/weewx-x.y.z/
                      examples: /usr/share/doc/weewx/examples/
                     utilities: /usr/bin/wee_*
