building the webserver
back-end (the http server) and front-end (the html and javascript code for the browsers) are both built when the build of the websrv optional library is requested.
You can include the web server interface components in your build using the build_oai script with the --build-lib "telnetsrv websrv" option.
The related cmake cache entry in ran_build/build/CMakeCache.txt for building the web server
is ENABLE_WEBSRV:BOOL=ON
When cmake configuration has been completed, with websrv enabled and all dependencies met,font-end and back-end
can be built separately, using respectively make websrvfront or make websrv from the build repository (replace make by ninja if you
build using ninja).
build example when back-end dependency is not installed
./build_oai --gNB --nrUE -w USRP --build-lib "telnetsrv websrv nrscope"
Will compile gNB
Will compile NR UE

You can fix this first dependency problem, the backend dependency, by installing the libulfius library:
On ubuntu: sudo apt-get install libulfius-dev, for fedora: dnf install libulfius. Some distribution don't have
libulfius package, instruction to install it can be found here

Currently the web server frontend can run with nodejs 18, you can check the version (if any) installed on your system entering the node -v command.
To prevent difficult situations with nodejs or npm versions it is better to specifically install the required nodejs version (after removing existing versions of npm and nodejs), as explained here for ubuntu. Similar instructions can be found for other distributions. It is also possible to make several nodejs versions co-habiting on your system, this is beyond this doc.
example: installing nodejs 18 on ubuntu
curl -s https://deb.nodesource.com/setup_18.x | sudo bash

Built target websrvfront
building and installing the back-end after cmake has been successfully configured
cd <oai repository>/openairinterface5g
source oaienv
cd cmake_targets
./build_oai --build-lib websrv
or, without the help of the build_oai script:
cd \<oai repository\>/openairinterface5g/cmake_targets/ran_build/build
make websrv
This will create the libwebsrv.so file in the targets/bin and cmake_targets/ran_build/build sub directories of the oai repository.
When starting the softmodem, you must specify the --websrv option to load and start the web server. The web server is loaded via the oai shared library loader.
Testing the web server interface
web server parameters
The web server back-end is using the oai configuration module. web server parameters must be specified in the websrv section.
| name | type | default | description |
|---|---|---|---|
listenaddr |
ipV4 address, ascii format |
"0.0.0.0" | local address the back-end is listening on |
listenport |
integer |
8090 | port number the server is listening on |
| debug | integer |
0 | When not 0, http requests headers and json objects dump are added to back-end traces |
| fpath | character string | websrv | The path to on-disk http server resources . The default value matches the front-end installation when running the softmodem from the executables repository. |
| cert, key, rootca | character string |
null | certificates and key used to trigger https protocol (not tested) |
running the back-end
To trigger the back-end use the --websrv option, possibly modifying the parameters as explained in the previous chapter. The two following commands allow starting the oai gNB and the oai 5G UE on the same computer, starting the telnet server and the web interface on both executables.
./nr-softmodem -O /usr/local/oai/conf/gnb.band78.sa.fr1.106PRB.usrpb210.conf --rfsim --rfsimulator.serveraddr server --telnetsrv --telnetsrv.listenstdin --websrv --rfsimulator.options chanmod
./nr-uesoftmodem -O /usr/local/oai/conf/nrue_sim.conf --sa --numerology 1 -r 106 -C 3649440000 --rfsim --rfsimulator.serveraddr 127.0.0.1 --websrv --telnetsrv --websrv.listenport 8092 --telnetsrv.listenport 8091
Connecting from a browser to the oai softmodem's
Assuming that the previous commands run successfully and that you also run your browser on the same host, you should be able to connect to the gNB and UE web interface using respectively the following url's:
http://127.0.0.1:8090/websrv/index.html
http://127.0.0.1:8092/websrv/index.html
The interface should be intuitive enough, keeping in mind the following restrictions:
- The command tab is not available if the telnet server is not enabled
- The softscope tab is not available if the xforms scope is started (
-doption) - Only one connection is supported to a back-end, especially for the scope interface
Some front-end objects, which usage are less intuitive provide a tooltip to help interface usage.
