no luck, no progress on getting weewx on CentOS 7.9

[Rich Painter]

CentOS 7.9 64bit clean install

Directions on http://weewx.com/docs/redhat.htm don't result in a workable weewx.

Note- those instructions do NOT have a step for wee_config --install

Starting weewx installation over from scratch....

Below is a complete transcript. One IMPORTANT thing to notice is the "installed drivers" output section seems to show there are a LOT of missing driver components!!!!

ALL of these steps are 100% repeatable. Variants using "wee_config --reconfigure" result in the SAME failures!

Anyone know who the creator of the rpm repo is??

Any help would be appreciated.

thanks

The rpm comes from the weewx team.

Your 'no module named usb' and 'no module named serial' and the seemingly missing things are because you didn't have all the prerequisite python modules (rpms) installed.  This is a longstanding known thing that has bitten many people over the years.  You have to install the prerequisites. 

Unfortunately CentOS is weird a.  I did a lot of testing of this in the v4 pre-release timeframe but did most of it using the setup.py (not rpm) method of installation.

 If you give me a couple hours I can probably do a quick test in a VM both ways to reverify vs. Centos-7.9

 

[vince]

ok - tested fine on a current vagrant centos image

 

The rpm is fine - you just probably used the RedHat 8 (python3) instructions by mistake rather than the RedHat 7 (python2) instructions...

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

   sudo curl -s http://weewx.com/yum/weewx-el7.repo | sudo tee /etc/yum.repos.d/weewx.repo

   sudo yum install weewx -y

If you have previously picked the wrong repo, you might need a 'sudo yum clean all' before (re)running the above.

[Rich Painter]

thanks Vince!

But I'm really confused... IF there are prerequisites then A)  they should be bolted into the rpm process. that is what rpms are for and B) they should be part of the WRITTEN instructions at the OFFICIAL weewx http://weewx.com/docs/redhat.htm for rehat/centos distributions.

I take it from your response that this is clearly a well-known (to some) weewx problem so why has not the fixes been written into the weewx http://weewx.com/docs/redhat.htm ??

I'm pleased and excited that you have responded with hope. I'm brand new to weewx but have used Ubuntu and CentOS for a very long time. I'm a 40-year C developer but have never known python. I have not been able to get weewx to run on either U20 or C7 !

thanks!

Vince,

Nope. I have only ever used the correct version 7 repo.... I posted the exact steps in my earlier request.... which you have restated here exactly to what I did....

Any other suggestions?

thanks

At the very top of that page I see this....

Install pre-requisites

For Redhat 8:

sudo yum install epel-release 

sudo yum install python3-cheetah

For Redhat 7:

sudo pip install pyserial pyusb

[Rich Painter]

Before posting anything I had already tried this

For Redhat 7:
sudo pip install pyserial pyusb

but CentOS 7.9 has no program pip !! so I had tried this:

[root@CRMG-Fremont weewx]# yum install pip

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirror.den01.meanservers.net
 * epel: mirror.oss.ou.edu
 * extras: mirror.den01.meanservers.net

 * updates: mirror.dal10.us.leaseweb.net
No package pip available.
Error: Nothing to do

So I assumed this was not a step for CentOS.... Obviously wrong.

What would the corresponding CentOS 7 program be for pip?

thanks

rich

What's going on is CentOS-7 is weird in general and especially for python-related things.

You need to get the pyserial and pyusb and  (optional) python2-pip rpms from the EPEL repository.

They are not bundled with CentOS-7 in the os's default repositories.  They're extras.

• sudo yum install epel-release
  
• sudo yum install -y pyserial pyusb
• sudo yum install -y python2-pip

CentOS also names things oddly, and sometimes you need to figure it out via  'yum search whatever' 

If you install the pyserial and pyusb corequisites, then wee_config will look right.

Installing pip is optional.

Now as for why the weewx rpms don't do this, remember that not all RHEL-based operating systems are the same, and our friends at RedHat make fascinatingly odd decisions all the time that result in trauma for their users.  We can't always explain why it's different or why bundling of things change massively sometimes (example - the repo structure in RHEL-8 is a train wreck).

Sometimes you just gotta deal with craziness from upstream...

[Rich Painter]

Vince,

roger that.

I had at the start enable the epel-release stuff as part of the CentOS 7.9 install. I have always included the epel in all centos installations.

The pip thing threw me since I never heard of it and it failed to install when I tried.

Just before you replied with this, I finally after being lead to this point tried:

yum install pyserial pyusb

and then the wee_config works!

For some reason I didnt need to do the python2-pip likely since centos doesnt have pip at all...

I have added these steps to my procedure! I hope others can be helped by this.

thanks

rich

You didn't need to install pip because it's optional for weewx.  If you dig a bit deeper you'll see you only need it when there's something python that isn't packaged in a rpm for your os version.

 

There's no rhyme or reason why RedHat did what they did re: python, or at least none that I've ever seen.    You basically always need EPEL on rh-7 based os's.  Things are a bit better with rh-8 based systems in that regard, but rh8 has some other nuances that bite some people.

FWIW if it was me setting up a clean centos system, I'd use 8 just to get it over with and get more recent software...but 7 will keep working til 2024 when it goes end of life.

 

[Rich Painter]

Vince,

i understand.

Long story... the CentOS 7 is required for an ICOM radio software called D-STAR ver 3. CO 8 will not work. So, if one is installing new for a system with D-STAR then CO7 it is regardless of the age. The prior ICOM release ver 2 required CO 5 !! We STILL have some of these running !!!

Thanks
