Deploying SIR Manually¶
If you want, you can deploy SIR manually. If you prefer to do it automatically go to the section Deploying SIR Automatically.
Note that rebooting the switch will uninstall pmacct and SIR. The data will still be there but the software has to be installed after every reboot. That’s why the automatic deployment is recommended.
For simplicity I am providing both pmacct and the dependencies (jansson) precompiled. If you prefer you can compile both yourself but that is outside the scope of this document. There are no changes from the original sources which you can get in the following links:
First you have to get all the related configuration files and copy them to the correct location:
lab#bash Arista Networks EOS shell [dbarroso@lab ~]$ cd /tmp/ [dbarroso@lab tmp]$ sudo ip netns exec ns-mgmtVRF wget https://sdn-internet-router-sir.readthedocs.io/en/latest/_static/eos_files.tar.gz --2015-07-28 13:30:35-- https://sdn-internet-router-sir.readthedocs.io/en/latest/_static/eos_files.tar.gz Resolving sdn-internet-router-sir.readthedocs.org... 220.127.116.11 Connecting to sdn-internet-router-sir.readthedocs.org|18.104.22.168|:80... connected.

If the database doesn’t exist yet, now you can just copy the empty database:
[dbarroso@lab tmp]$ sudo cp eos_files/pmacct/pmacct.db /mnt/drive/sir/output/
And finally, start pmacct:
[dbarroso@lab tmp]$ sudo immortalize --log=/var/log/pmacct.log --daemonize /usr/sbin/sfacctd -f /etc/pmacct.conf
Installing SIR is very easy. You can install it by using PIP as any other python package:
lab#bash Arista Networks EOS shell [dbarroso@lab ~]$ cd /tmp [dbarroso@lab tmp]$ sudo ip netns exec ns-mgmtVRF pip install SIR Downloading/unpacking SIR Downloading SIR-0.10.tar.gz (79kB): 79kB downloaded Running setup.py (path:/tmp/pip_build_root/SIR/setup.py) egg_info for package SIR ... Successfully installed SIR flask ipaddress Werkzeug Jinja2 itsdangerous MarkupSafe Cleaning up...
Instead of running our own HTTP and/or application server we are just going to use the services that EOS is already using for their eAPI. For that you just have to copy a couple of configuration files that were provided in the same tar file you downloaded before:
[dbarroso@lab tmp]$ sudo cp eos_files/sir_uwsgi.ini /etc/uwsgi/ [dbarroso@lab tmp]$ sudo cp eos_files/sir_nginx.conf /etc/nginx/external_conf/
Now, copy the configuration file for SIR:
[dbarroso@lab tmp]$ sudo cp eos_files/sir_settings.py /mnt/drive/sir/settings.py
Starting the application server and SIR¶
To start SIR you just have to start application server:
[dbarroso@lab tmp]$ sudo SIR_SETTINGS='/mnt/drive/sir/settings.py' immortalize --daemonize --log=/var/log/sir.uwsgi.log /usr/bin/uwsgi --ini /etc/uwsgi/sir_uwsgi.ini
And finally you have to restart the HTTP server back in the EOS CLI. Assuming you already have the eAPI enabled:
[dbarroso@lab tmp]$ exit logout lab#conf lab(config)#management api http-commands lab(config-mgmt-api-http-cmds)#shut lab(config-mgmt-api-http-cmds)#no shut
