Resolved Plex Onyx to work with Python

[Carlos Antolinez]

Hi, I would like to work with python in a server Centos 7 with Plesk Onyx version 17.0.17.

I can give certain information about my configuration:
1) In Tools & Settings > Apache Web Server > check python. I no have this options to check it.

2) In my console I have :
[root@server1 ~]# python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

3) Mod python is not installed
[root@server1 ~]# rpm -q mod_python
package mod_python is not installed

And finally, when I execute a file test2.py I have this result:
#!/usr/bin/env python
# -*- coding: UTF-8 -*-

# enable debugging
import cgitb
cgitb.enable()

print "Content-Type: text/plain;charset=utf-8"
print

print "Hello World!"

At this point I don´t know what is exactly my problem. I´ve read about this but I not have nothing especific to do. Someone could help me?

Thanks a lot

Carlos

Hi Carlos Antolinez,

pls. note: "mod_python" is not shipped by CentOS anymore. Pls. consider to compile "mod_python" with these example commands:

Pls. start with some basics:

yum group install "Development Tools"

or

yum groupinstall "Development Tools"

or/and

yum install gcc-c++ pcre-devel zlib-devel make unzip

Install "python-devel" and "httpd-devel":

yum -y install python-devel httpd-devel

Get the latest "mod_python" source with "wget" from => Index of /dist

cd /usr/local/src/
wget http://dist.modpython.org/dist/mod_python-3.5.0.tgz
tar xfz mod_python-3.5.0.tgz

Configure and compile your "mod_python" - source:

cd /usr/local/src/mod_python-3.5.0
./configure
make
make install

Finally, enable the module for your apache - server with for example:

echo 'LoadModule python_module modules/mod_python.so' > /etc/httpd/conf.modules.d/99-python.conf
systemctl restart httpd.service

Could you pls. explain HOW you executed "test2.py"? Consider to use the example commands

cd /var/www/vhosts/YOUR-DOMAIN.COM/httpdocs
./test2.py

Did you probably miss to set the correct permissions for "test2.py"? ( consider to use: chmod +x /var/www/vhosts/YOUR-DOMAIN.COM/httpdocs/test2.py )

Thank you very much UFHH01. I´ll try your instructions.

Regarding your question about I executed "test2.py" : I´ve tried from crhome because I want to work with python in web. I´m very new with Python and I´m reading about to learn, yet.

Hello,

Nowadays almost no-one uses mod_python to run and applications - you can consider to use passenger to host the python application, especially you use modern python frameworks

Hi Mizar, how can I do that.

In fact I want to try test a mqttwarn (GitHub - jpmens/mqttwarn: Subscribe to MQTT topics (with wildcards) and notifiy pluggable services ) in a server centos 7 with plesk, but I can´t do it. I suppuse that the problem is executing python.
------------------------------------------
I followed the steps of UFHH01, and all was well but when I try finally( systemctl restart httpd.service) I have this error
[root@server1 Python-3.5.2]# systemctl restart httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

 

[UFHH01]

Hi Carlos Antolinez,

when you see outputs like

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

... pls. FOLLOW the suggestions, in order to investigate possible issues/errors/problems, because no one is able to guess, what the issue/error/problem might be.


If the issue/error/problem is because you recently added "echo 'LoadModule python_module modules/mod_python.so' > /etc/httpd/conf.modules.d/99-python.conf", pls. CHECK, that "mod_python.so" exist at the defined path and correct the path if necessary. Use a "locate" - command for example ( requires "mlocate" to be installed on your server - consider to use the => Search | Plesk Forum , if you need more informations to installation and usage of "mlocate" ), which should point you to the exact location of "mod_python.so" on your server.

As I see mqttwarn is not a web application, so you don't need to use passenger or mod python - and you only need to install required python modules

Ok, thank you very much for all, I´ll try to do all of you said and additionaly I go to learn (reading) about this, I think that with your tips and a little bit information I´ll resolve this milestone.
