<p>
|
|
This is a guide to installing WeeWX from an RPM package on systems such as Redhat, CentOS or Fedora.
|
|
</p>
|
|
|
|
<h2>Install pre-requisites</h2>
|
|
|
|
<p>
|
|
Unfortunately, not everything that WeeWX uses is included in the standard Redhat 8 and Redhat 7 repositories. You
|
|
will need to enable their respective EPEL ("Extra Packages for Enterprise Linux") repositories, then install some
|
|
prerequisites manually.
|
|
</p>
|
|
|
|
|
|
<div id="prereq-tabs">
|
|
<nav>
|
|
<button class="tab" onclick="openTab(event, '#prereq-redhat-8')">
|
|
Redhat 8<br/>Centos 8
|
|
</button>
|
|
|
|
<button class="tab" onclick="openTab(event, '#prereq-redhat-7')">
|
|
Redhat 7<br/>Centos 7
|
|
</button>
|
|
|
|
</nav>
|
|
</div>
|
|
|
|
|
|
<div id="prereq-redhat-8" class="tab-content">
|
|
<p>
|
|
For Redhat 8 and Centos 8, you will be using Python 3. Here are the pre-requisites:
|
|
</p>
|
|
<pre class='tty cmd'>sudo yum install epel-release
|
|
sudo yum install python3-cheetah</pre>
|
|
</div>
|
|
|
|
<div id="prereq-redhat-7" class="tab-content">
|
|
<p>
|
|
For Redhat 7 and Centos 7, you will be using Python 2. Here are the pre-requisites:
|
|
</p>
|
|
<pre class="tty cmd">
|
|
sudo yum install epel-release
|
|
sudo yum install pyserial pyusb
|
|
sudo yum install python2-pip # (Optional)</pre>
|
|
|
|
</div>
|
|
|
|
|
|
<h2>Configure yum</h2>
|
|
|
|
<p>Tell <span class="code">yum</span> (or <span class="code">dnf</span>) where to find the WeeWX releases. This only has
|
|
to be done once - the first time you install WeeWX.
|
|
</p>
|
|
|
|
Tell your system to trust weewx.com:
|
|
<pre class='tty cmd'>sudo rpm --import http://weewx.com/keys.html</pre>
|
|
|
|
For Redhat 8, using Python 3:
|
|
<pre class='tty cmd'>curl -s http://weewx.com/yum/weewx-el8.repo | sudo tee /etc/yum.repos.d/weewx.repo</pre>
|
|
|
|
For Redhat 7, using Python 2:
|
|
<pre class='tty cmd'>curl -s http://weewx.com/yum/weewx-el7.repo | sudo tee /etc/yum.repos.d/weewx.repo</pre>
|
|
|
|
<h2>Install WeeWX</h2>
|
|
|
|
<p>
|
|
Install WeeWX using <span class="code">yum</span> (or <span class="code">dnf</span>). When you are done, WeeWX will
|
|
be running the Simulator in the background as a daemon.
|
|
</p>
|
|
|
|
<pre class='tty cmd'>sudo yum install weewx</pre>
|
|
|
|
<h2>Status</h2>
|
|
|
|
<p>Look in the system log for messages from WeeWX.</p>
|
|
<pre class='tty cmd'>sudo tail -f /var/log/messages</pre>
|
|
|
|
<h2>Verify</h2>
|
|
<p>
|
|
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 <a
|
|
href="usersguide.htm#archive_interval">archive interval</a> set in your hardware.
|
|
</p>
|
|
<pre class='tty'><a href="file:///var/www/html/weewx/index.html">file:///var/www/html/weewx/index.html</a></pre>
|
|
|
|
<h2>Configure</h2>
|
|
<p>
|
|
The default installation uses Simulator as the <span class='code'>station_type</span>. To use real hardware, stop
|
|
WeeWX, change to the actual station type and station parameters, delete the simulation data, then restart WeeWX:
|
|
</p>
|
|
<pre class='tty cmd'>sudo /etc/init.d/weewx stop
|
|
sudo wee_config --reconfigure
|
|
sudo rm /var/lib/weewx/weewx.sdb
|
|
sudo /etc/init.d/weewx start</pre>
|
|
|
|
<h2>Start/Stop</h2>
|
|
<p>To start/stop WeeWX:</p>
|
|
<pre class='tty cmd'>sudo /etc/init.d/weewx start
|
|
sudo /etc/init.d/weewx stop</pre>
|
|
|
|
<h2>Customize</h2>
|
|
<p>
|
|
To enable uploads such as Weather Underground or to customize reports, modify the configuration file <span
|
|
class='code'>/etc/weewx/weewx.conf</span>. See the <a href="usersguide.htm">User Guide</a> and <a
|
|
href="customizing.htm">Customization Guide</a> for details.
|
|
</p>
|
|
<p>
|
|
WeeWX must be restarted for configuration file changes to take effect.
|
|
</p>
|
|
|
|
<h2>Uninstall</h2>
|
|
<p>To uninstall WeeWX, removing configuration files but retaining data:</p>
|
|
<pre class='tty cmd'>sudo yum remove weewx</pre>
|
|
<p>To remove data:</p>
|
|
<pre class='tty cmd'>sudo rm -r /var/lib/weewx
|
|
sudo rm -r /var/www/html/weewx</pre>
|
|
|
|
<h2>Layout</h2>
|
|
<p>The installation will result in the following layout:</p>
|
|
<table class='locations' style='width: auto;'>
