ansible-openwisp2

Ansible role that installs the OpenWISP Server Application.

Tested on Debian (Buster, Bullseye), Ubuntu (18/20/22 LTS).

NOTE: it is highly suggested to use this procedure on clean virtual machines or linux containers.

Recommended ansible version: 2.10.

Architecture

For more information, see OpenWISP Architecture.

System Requirements

The following specifications will run a new, empty instance of OpenWISP. Please ensure you account for the amount of disk space your use case will require, e.g. allocate enough space for users to upload floor plan images.

Hardware requirements (Recommended)

2 CPUs
2 GB Memory
Disk space - depends on the projected size of your database and uploaded photo images

Keep in mind that increasing the number of celery workers will require more memory and CPU. You will need to increase the amount of celery workers as the number of devices you manage grows.

For more information about how to increase concurrency, look for the variables which end with _concurrency or _autoscale in the Role Variables section.

Software

Generally a fresh installation of one of the supported operating systems is sufficient; no pre-configuration required. The Ansible Playbook will install and configure all dependencies and leave you with a running OpenWISP installation.

Tips: Ensure the hostname of your target machine matches what is in your Ansible configuration file. Also, please ensure that Ansible can access your target machine by SSH, be it either with a key or password. For more information see the Ansible Getting Started Documentation.

Supported Operating Systems

See the section "OS Platforms" on the ansible-galaxy page of ansible-openwisp2.

Usage (tutorial)

If you don't know how to use ansible, don't panic, this procedure will guide you towards a fully working basic openwisp2 installation.

If you already know how to use ansible, you can skip this tutorial.

First of all you need to understand two key concepts:

for "production server" we mean a server (not a laptop or a desktop computer!) with public ipv4 / ipv6 which is used to host openwisp2
for "local machine" we mean the host from which you launch ansible, eg: your own laptop

Ansible is a configuration management tool that works by entering production servers via SSH, so you need to install it and configure it on the machine where you launch the deployment and this machine must be able to SSH into the production server.

Ansible will be run on your local machine and from there it will connect to the production server to install openwisp2.

If you are trying to install OpenWISP2 on your laptop or desktop pc just for testing purposes, please read Install OpenWISP2 for testing in a VirtualBox VM.

Install ansible

Install ansible (recommended version 2.10) on your local machine (not the production server!) if you haven't done already.

To install ansible we suggest you follow the official ansible installation guide. It is recommended to install ansible through a virtual environment to avoid dependency issues.

Please ensure that you have the correct version of Jinja installed in your Python environment:

pip install Jinja2>=2.11

After having installed ansible, you need to install git (example for linux debian/ubuntu systems):

sudo apt-get install git

Install this role

For the sake of simplicity, the easiest thing is to install this role on your local machine via ansible-galaxy (which was installed when installing ansible), therefore run:

ansible-galaxy install openwisp.openwisp2

Ensure that you have correct version of community.general collection installed

ansible-galaxy collection install "community.general:>=3.6.0"

Choose a working directory

Choose a working directory on your local machine where to put the configuration of openwisp2.

This will be useful when you will need to upgrade openwisp2.

Eg:

mkdir ~/openwisp2-ansible-playbook
cd ~/openwisp2-ansible-playbook

Putting this working directory under version control is also a very good idea.

Create inventory file

The inventory file is where group of servers are defined. In our simple case we can get away with defining just one group in which we will put just one server.

Create a new file called hosts in your local machine's working directory (the directory just created in the previous step), with the following contents:

[openwisp2]
openwisp2.mydomain.com

Substitute openwisp2.mydomain.com with your production server's hostname - DO NOT REPLACE openwisp2.mydomain.com WITH AN IP ADDRESS, otherwise email sending through postfix will break, causing 500 internal server errors on some operations.

Create playbook file

Create a new playbook file playbook.yml on your local machine with the following contents:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_default_from_email: "[email protected]"

The line become: "{{ become | default('yes') }}" means ansible will use the sudo program to run each command. You may remove this line if you don't need it (eg: if you are root user on the production server).

You may replace openwisp2 on the hosts field with your production server's hostname if you desire.

Substitute [email protected] with what you deem most appropriate as default sender for emails sent by OpenWISP 2.

Run the playbook

Now is time to deploy openwisp2 to the production server.

Run the playbook from your local machine with:

ansible-playbook -i hosts playbook.yml -u <user> -k --become -K

Substitute <user> with your production server's username.

The -k argument will need the sshpass program.

You can remove -k, --become and -K if your public SSH key is installed on the server.

Tips:

If you have an error like Authentication or permission failure then try to use root user ansible-playbook -i hosts playbook.yml -u root -k
If you have an error about adding the host's fingerprint to the known_hosts file, you can simply connect to the host via SSH and answer yes when prompted; then you can run ansible-playbook again.

When the playbook is done running, if you got no errors you can login at:

https://openwisp2.mydomain.com/admin
username: admin
password: admin

Substitute openwisp2.mydomain.com with your production server's hostname.

Now proceed with the following steps:

change the password (and the username if you like) of the superuser as soon as possible
update the name field of the default Site object to accurately display site name in email notifications
edit the information of the default organization
in the default organization you just updated, note down the automatically generated shared secret option, you will need it to use the auto-registration feature of openwisp-config
this Ansible role creates a default template to update authorized_keys on networking devices using the default access credentials. The role will either use an existing SSH key pair or create a new one if no SSH key pair exists on the host machine.

Now you are ready to start configuring your network! If you need help you can ask questions on one of the official OpenWISP Support Channels.

Install ansible-openwisp2 for development

If you need to modify the logic of this ansible role and you need to test your changes here we explain how to do it.

First of all, create the directory where you want to place the repositories of the ansible roles and create directory roles.

    mkdir -p ~/openwisp-dev/roles
    cd ~/openwisp-dev/roles

Clone ansible-openwisp2 and Stouts.postfix as follows:

    git clone https://github.com/openwisp/ansible-openwisp2.git openwisp.openwisp2
    git clone https://github.com/Stouts/Stouts.postfix

Now, go to the parent directory & create hosts file and playbook.yml:

    cd ../
    touch hosts
    touch playbook.yml

From here on you can follow the instructions available at the following sections:

Create inventory file
Create playbook file
Run the playbook

Note: Please remember to install ansible.

All done!

How to run tests

If you want to contribute to ansible-openwisp2 you should run tests in your development environment to ensure your changes are not breaking anything.

To do that, proceed with the following steps:

Step 1: Clone ansible-openwisp2

Clone repository by:

git clone https://github.com/<your_fork>/ansible-openwisp2.git openwisp.openwisp2

Step 2: Install docker

If you haven't installed docker yet, you need to install it (example for linux debian/ubuntu systems):

sudo apt-get install docker.io

Step 3: Install molecule and dependences

pip install molecule[docker] yamllint ansible-lint docker

Step 4: Download docker images

docker pull geerlingguy/docker-ubuntu2204-ansible:latest
docker pull geerlingguy/docker-ubuntu2004-ansible:latest
docker pull geerlingguy/docker-ubuntu1804-ansible:latest
docker pull geerlingguy/docker-debian10-ansible:latest
docker pull geerlingguy/docker-debian11-ansible:latest

Step 5: Run molecule test

molecule test -s local

If you don't get any error message it means that the tests ran successfully without errors.

ProTip: Use molecule test --destroy=never to speed up subsequent test runs.

Install OpenWISP2 for testing in a VirtualBox VM

If you want to try out OpenWISP 2 in your own development environment, the safest way is to use a VirtualBox Virtual Machine (from here on VM).

Using Vagrant

Since August 2018 there's a new fast and easy way to install OpenWISP 2 for testing purposes leveraging Vagrant, a popular open source tool for building and maintaining portable virtual software development environments.

To use this new way, clone the repository vagrant-openwisp2, it contains the instructions (in the README.md) and the vagrant configuration to perform the automatic installation.

Alternatively, you can read on to learn how to install VirtualBox and run ansible-openwisp2 manually, this is useful if you need to test advanced customisations of OpenWISP.

Installing Debian 9 on VirtualBox

Install VirtualBox and create a new Virtual Machine running Debian 10. A step-by-step guide is available here, however we need to change a few things to get ansible working.

VM configuration

Proceed with the installation as shown in the guide linked above, and come back here when you see this screen:

We're only running this as a server, so you can uncheck Debian desktop environment. Make sure SSH server and standard system utilities are checked.

Next, add a Host-only Network Adapter and assign an IP address to the VM.

On the Main VirtualBox page, Go to File > Host Network Manager
Click the + icon to create a new adapter
Set the IPv4 address to 192.168.56.1 and the IPv4 Network Mask to 255.255.255.0. You may need to select Configure Adapter Manually to do this. The IPv6 settings can be ignored
Shut off your VM
In your VM settings, in the Network section, click Adapter 2 and Enable this Adapter
Select Host-only adapter and the name of the adapter you created
Boot up your VM, run su, and type in your superuser password
Run ls /sys/class/net and take note of the output
Run nano /etc/network/interfaces and add the following at the end of the file:
```
  auto enp0s8
  iface enp0s8 inet static
      address 192.168.56.2
      netmask 255.255.255.0
      network 192.168.56.0
      broadcast 192.168.56.255
```
Replace enp0s8 with the network interface not present in the file but is shown when running ls /sys/class/net
Save the file with CtrlO then Enter, and exit with CtrlX
Restart the machine by running reboot

Make sure you can access your VM via ssh:

ssh 192.168.56.2

Back to your local machine

Proceed with these steps in your local machine, not the VM.

Step 1: Install ansible

Step 2: Install the OpenWISP2 role for Ansible

Step 3: Set up a working directory

Step 4: Create the hosts file

Create an ansible inventory file named hosts in your working directory (i.e. not in the VM) with the following contents:

[openwisp2]
192.168.56.2

Step 5: Create the ansible playbook

In the same directory where you created the host file, create an empty file named playbook.yml which contains the following:

- hosts: openwisp2
  roles:
    - openwisp.openwisp2
  # the following line is needed only when an IP address is used as the inventory hostname
  vars:
      postfix_myhostname: localhost

Step 6: Run the playbook

ansible-playbook -i hosts playbook.yml -b -k -K --become-method=su

When the playbook ran successfully, you can log in at:

https://192.168.56.2/admin
username: admin
password: admin

Enabling the Monitoring module

The Monitoring module is enabled by default, it can be disabled by setting openwisp2_monitoring to false.

Enabling the Network Topology module

To enable the Network Topology module you need to set openwisp2_network_topology to true in your playbook.yml file. Here's a short summary of how to do this:

Step 1: Install ansible

Step 2: Install this role

Step 3: Create inventory file

Step 4: Create a playbook file with following contents:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_network_topology: true

Step 5: Run the playbook

When the playbook is done running, if you got no errors you can login at:

https://openwisp2.mydomain.com/admin
username: admin
password: admin

Enabling the Firmware Upgrader module

Note: It is encouraged that you read the quick-start guide of openwisp-firmware-upgrader before going ahead.

To enable the Firmware Upgrader module you need to set openwisp2_firmware_upgrader to true in your playbook.yml file. Here's a short summary of how to do this:

Step 1: Install ansible

Step 2: Install this role

Step 3: Create inventory file

Step 4: Create a playbook file with following contents:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_firmware_upgrader: true

Step 5: Run the playbook

When the playbook is done running, if you got no errors you can login at:

https://openwisp2.mydomain.com/admin
username: admin
password: admin

Note: You can configure openwisp-firmware-upgrader specific settings using the openwisp2_extra_django_settings or openwisp2_extra_django_settings_instructions.

E.g:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_firmware_upgrader: true
    openwisp2_extra_django_settings_instructions:
      - |
        OPENWISP_CUSTOM_OPENWRT_IMAGES = (
            ('my-custom-image-squashfs-sysupgrade.bin', {
                'label': 'My Custom Image',
                'boards': ('MyCustomImage',)
            }),
        )

Enabling the RADIUS module

To enable the RADIUS module you need to set openwisp2_radius to true in your playbook.yml file. Here's a short summary of how to do this:

Step 1: Install ansible

Step 2: Install this role

Step 3: Create inventory file

Step 4: Create a playbook file with following contents:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_radius: true
    openwisp2_freeradius_install: true
    # set to false when you don't want to register openwisp-radius
    # API endpoints.
    openwisp2_radius_urls: true

Note: openwisp2_freeradius_install option provides a basic configuration of freeradius for openwisp, it sets up the radius user token mechanism if you want to use another mechanism or manage your freeradius separately, please disable this option by setting it to false.

Step 5: Run the playbook

When the playbook is done running, if you got no errors you can login at:

https://openwisp2.mydomain.com/admin
username: admin
password: admin

Note: for more information regarding radius configuration options, look for the word "radius" in the Role variables section of this document.

Configuring CORS Headers

While integrating OpenWISP with external services, you can run into issues related to CORS (Cross-Origin Resource Sharing). This role allows users to configure the CORS headers with the help of django-cors-headers package. Here's a short summary of how to do this:

Step 1: Install ansible

Step 2: Install this role

Step 3: Create inventory file

Step 4: Create a playbook file with following contents:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    # Cross-Origin Resource Sharing (CORS) settings
    openwisp2_django_cors:
      enabled: true
      allowed_origins_list:
        - https://frontend.openwisp.org
        - https://logs.openwisp.org

Note: to learn about the supported fields of the openwisp2_django_cors variable, look for the word "openwisp2_django_cors" in the Role variables section of this document.

Step 5: Run the playbook

When the playbook is done running, if you got no errors you can login at:

https://openwisp2.mydomain.com/admin
username: admin
password: admin

The ansible-openwisp2 only provides abstraction (variables) for handful of settings available in django-cors-headers module. Use the openwisp2_extra_django_settings_instructions or openwisp2_extra_django_settings variable to configure additional setting of django-cors-headers as shown in the following example:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - openwisp.openwisp2
  vars:
    openwisp2_django_cors:
      enabled: true
      allowed_origins_list:
        - https://frontend.openwisp.org
        - https://logs.openwisp.org
      replace_https_referer: true
    # Configuring additional settings for django-cors-headers
    openwisp2_extra_django_settings_instructions:
      - |
        CORS_ALLOW_CREDENTIALS = True
        CORS_ALLOW_ALL_ORIGINS = True

Deploying custom static content

For deploying custom static content (HTML files, etc.) add all the static content in files/ow2_static directory. The files inside files/ow2_static will be uploaded to a directory named static_custom in openwisp2_path.

This is helpful for customizing OpenWISP's theme.

E.g., if you added a custom CSS file in files/ow2_static/css/custom.css, the file location to use in OPENWISP_ADMIN_THEME_LINKS setting will be css/custom.css.

Troubleshooting

OpenWISP 2 is deployed using uWSGI, it also uses daphne fo WebSockets and celery as task queue.

All this services are run by supervisor.

sudo service supervisor start|stop|status

You can view each individual process run by supervisor with the next command.

More info at Running supervisorctl

sudo supervisorctl status

nginx is in front of uWSGI. You can control it with next command

service nginx status start|stop|status

OpenWISP 2 is installed in /opt/openwisp2 (unless you changed the openwisp2_path variable in the ansible playbook configuration), these are some useful directories to look for when experiencing issues.

Location	Description
/opt/openwisp2	The OpenWISP 2 root dir.
/opt/openwisp2/log	Log files
/opt/openwisp2/env	Python virtual env
/opt/openwisp2/db.sqlite3	OpenWISP 2 sqlite database

All processes are running as www-data user.

If you need to copy or edit files, you can switch to www-data user with the commands

sudo su www-data -s /bin/bash
cd /opt/openwisp2
source env/bin/activate

SSL certificate gotchas

When you access the admin website you will get an SSL certificate warning because the playbook creates a self-signed (untrusted) SSL certificate. You can get rid of the warning by installing your own trusted certificate and set the openwisp2_ssl_cert and openwisp2_ssl_key variables accordingly or by following the instructions explained in the section "Automatic SSL certificate".

If you keep the untrusted certificate, you will also need to disable SSL verification on devices using openwisp-config by setting verify_ssl to 0, although I advice against using this kind of setup in a production environment.

Automatic SSL certificate

This section explains how to automatically install and renew a valid SSL certificate signed by letsencrypt.

The first thing you have to do is to setup a valid domain for your openwisp2 instance, this means your inventory file (hosts) should look like the following:

[openwisp2]
openwisp2.yourdomain.com

You must be able to add a DNS record for openwisp2.yourdomain.com, you cannot use an ip address in place of openwisp2.yourdomain.com.

Once your domain is set up and the DNS record is propagated, proceed by installing the ansible role geerlingguy.certbot:

ansible-galaxy install geerlingguy.certbot

Then proceed to edit your playbook.yml so that it will look similar to the following example:

- hosts: openwisp2
  become: "{{ become | default('yes') }}"
  roles:
    - geerlingguy.certbot
    - openwisp.openwisp2
  vars:
    # SSL certificates
    openwisp2_ssl_cert: "/etc/letsencrypt/live/{{ inventory_hostname }}/fullchain.pem"
    openwisp2_ssl_key: "/etc/letsencrypt/live/{{ inventory_hostname }}/privkey.pem"

    # certbot configuration
    certbot_auto_renew_minute: "20"
    certbot_auto_renew_hour: "5"
    certbot_create_if_missing: true
    certbot_auto_renew_user: "<privileged-users-to-renew-certs>"
    certbot_certs:
      - email: "<paste-your-email>"
        domains:
          - "{{ inventory_hostname }}"
  pre_tasks:
    - name: Update APT package cache
      apt:
        update_cache: true
      changed_when: false
      retries: 5
      delay: 10
      register: result
      until: result is success

Read the documentation of geerlingguy.certbot to learn more about configuration of certbot role.

Once you have set up all the variables correctly, run the playbook again.

Upgrading openwisp2

It's highly recommended to back up your current instance before upgrading.

Update this ansible-role via ansible-galaxy:

ansible-galaxy install --force openwisp.openwisp2

Run ansible-playbook again from your local machine:

ansible-playbook -i hosts playbook.yml

You may also run the playbook automatically periodically or when a new release of OpenWISP2, for example, by setting up a continuous integration system.

Role variables

This role has many variables values that can be changed to best suit your needs.

Below are listed all the variables you can customize (you may also want to take a look at the default values of these variables).

- hosts: yourhost

Note: The default values for settings provided to control the number of process and threads of uWSGI and Daphne are set conservatively. It is expected from user to update these settings to suit scale of their project. The same thing applies for concurrency and autoscale settings for celery workers.
