# OpenWifi hello world (ow_helloworld)
|
||||
|
||||
## What is this?
|
||||
This is a skeleton Micro Service that shows off all the basic facilities of the OW architecture.
|
||||
|
||||
## Building
|
||||
In order to build the uCentralGW, you will need to install its dependencies, which includes the following:
|
||||
- cmake
|
||||
- boost
|
||||
- POCO 1.11.1 or later (special build)
|
||||
- a C++17 compiler
|
||||
- libyaml
|
||||
- openssl
|
||||
- libpq-dev (PortgreSQL development libraries)
|
||||
- mysql-client (MySQL client)
|
||||
- librdkafka
|
||||
- cppkafka
|
||||
|
||||
The build is done in 2 parts. The first part is to build a local copy of the framework tailored to your environment. This
|
||||
framework is called [Poco](https://github.com/pocoproject/poco). The version used in this project has a couple of fixes
|
||||
from the master copy needed for cmake. Please use the version of this [Poco fix](https://github.com/stephb9959/poco). Building
|
||||
Poco may take several minutes depending on the platform you are building on.
|
||||
|
||||
### Ubuntu/Debian
|
||||
These instructions have proven to work on Ubuntu 20.4.
|
||||
```
|
||||
sudo apt install git cmake g++ libssl-dev libmariadb-dev
|
||||
sudo apt install libpq-dev libaprutil1-dev apache2-dev libboost-all-dev
|
||||
sudo apt install librdkafka-dev libmysqlclient-dev default-libmysqlclient-dev
|
||||
|
||||
git clone https://github.com/stephb9959/poco
|
||||
cd poco
|
||||
mkdir cmake-build
|
||||
cd cmake-build
|
||||
cmake ..
|
||||
cmake --build . --config Release
|
||||
sudo cmake --build . --target install
|
||||
|
||||
git clone https://github.com/stephb9959/cppkafka
|
||||
cd cppkafka
|
||||
mkdir cmake-build
|
||||
cd cmake-build
|
||||
cmake ..
|
||||
cmake --build . --config Release
|
||||
sudo cmake --build . --target install
|
||||
|
||||
cd ~
|
||||
git clone https://github.com/Telecominfraproject/wlan-cloud-tools
|
||||
cd wlan-cloud-tools
|
||||
cd microservice_sample
|
||||
mkdir cmake-build
|
||||
cd cmake-build
|
||||
cmake ..
|
||||
make -j
|
||||
```
|
||||
|
||||
### After completing the build
|
||||
After completing the build, you can remove the Poco source as it is no longer needed.
|
||||
|
||||
#### Expected directory layout
|
||||
From the directory where your cloned source is, you will need to create the `certs`, `logs`, and `uploads` directories.
|
||||
```shell
|
||||
mkdir certs
|
||||
mkdir logs
|
||||
mkdir data
|
||||
```
|
||||
|
||||
### Certificates
|
||||
Love'em of hate'em, we gotta use'em. So we tried to make this as easy as possible for you.
|
||||
|
||||
#### The `certs` directory
|
||||
For all deployments, you will need the following certs directory, populated with the proper files.
|
||||
|
||||
```asm
|
||||
certs ---+
|
||||
+--- restapi-ca.pem
|
||||
+--- restapi-cert.pem
|
||||
+--- restapi-key.pem
|
||||
```
|
||||
|
||||
#### Configuration
|
||||
The configuration for this service is kept in a properties file. This file is called `owgw.properties` and you can
|
||||
see the latest version [here](https://github.com/Telecominfraproject/wlan-cloud-ucentralgw/blob/main/owgw.properties). The file will be loaded from
|
||||
the directory set by the environment variable `UCENTRALGW_CONFIG`. To use environment variables in the configuration,
|
||||
you must use `$<varname>`. Only `path names` support the use of environment variables. The sample configuration requires very
|
||||
little changes if you keep the suggested directory structure. For the sample configuration to work, you need to define 2
|
||||
environment variables.
|
||||
```
|
||||
export OWGW_ROOT=`pwd`
|
||||
export UCENTRALGW_CONFIG=`pwd`
|
||||
```
|
||||
If you current working directory is the root of the project, this will set the variables properly. Otherwise, you can set the variables
|
||||
to point to wherever is necessary.
|
||||
|
||||
##### Important config entries
|
||||
###### This is the logging directory
|
||||
```
|
||||
logging.channels.c2.path = $OWGW_ROOT/logs/sample.log
|
||||
```
|
||||
|
||||
###### This is the type of storage in use
|
||||
```asm
|
||||
storage.type = sqlite
|
||||
```
|
||||
|
||||
###### Autoprovisioning settings
|
||||
```asm
|
||||
openwifi.autoprovisioning = true
|
||||
openwifi.devicetypes.0 = AP:linksys_ea8300,edgecore_eap101,linksys_e8450-ubi
|
||||
openwifi.devicetypes.1 = SWITCH:edgecore_ecs4100-12ph
|
||||
openwifi.devicetypes.2 = IOT:esp32
|
||||
```
|
||||
|
||||
###### This is the RESTAPI endpoint
|
||||
|
||||
```asm
|
||||
openwifi.restapi.host.0.backlog = 100
|
||||
openwifi.restapi.host.0.security = relaxed
|
||||
openwifi.restapi.host.0.rootca = $OWHELLOW_ROOT/certs/restapi-ca.pem
|
||||
openwifi.restapi.host.0.address = *
|
||||
openwifi.restapi.host.0.port = 16002
|
||||
openwifi.restapi.host.0.cert = $OWHELLOW_ROOT/certs/restapi-cert.pem
|
||||
openwifi.restapi.host.0.key = $OWHELLOW_ROOT/certs/restapi-key.pem
|
||||
openwifi.restapi.host.0.key.password = mypassword
|
||||
|
||||
openwifi.internal.restapi.host.0.backlog = 100
|
||||
openwifi.internal.restapi.host.0.security = relaxed
|
||||
openwifi.internal.restapi.host.0.rootca = $OWHELLOW_ROOT/certs/restapi-ca.pem
|
||||
openwifi.internal.restapi.host.0.address = *
|
||||
openwifi.internal.restapi.host.0.port = 17002
|
||||
openwifi.internal.restapi.host.0.cert = $OWHELLOW_ROOT/certs/restapi-cert.pem
|
||||
openwifi.internal.restapi.host.0.key = $OWHELLOW_ROOT/certs/restapi-key.pem
|
||||
openwifi.internal.restapi.host.0.key.password = mypassword
|
||||
```
|
||||
|
||||
##### This is the end point for the devices to connect with
|
||||
This is the crucial section. I bet that 97.4% of all your problems will come from here, and it's boring. So put some good music on,
|
||||
give the kids the iPad, get a cup of coffee, and pay attention. Every field will be explained.
|
||||
|
||||
###### openwifi.websocket.host.0.backlog
|
||||
This is the number of concurrent devices you are expecting to call all at once. Not the current number of devices. This is how many will connect in the same exact second.
|
||||
Take the total number of devices you have and divide by 100. That's a good rule of thumb. Never go above 500.
|
||||
|
||||
###### openwifi.websocket.host.0.rootca
|
||||
This is the root file as supplied by Digicert. You can find it [here](https://github.com/Telecominfraproject/wlan-cloud-ucentralgw/blob/main/certificates/root.pem)
|
||||
|
||||
###### openwifi.websocket.host.0.issuer
|
||||
This is the issuer file as supplied by Digicert. You can find it [here](https://github.com/Telecominfraproject/wlan-cloud-ucentralgw/blob/main/certificates/issuer.pem)
|
||||
|
||||
###### openwifi.websocket.host.0.cert
|
||||
This is a `pem` file that you will receive from Digicert for the gateway itself. This is the certificate for the gateway.
|
||||
|
||||
###### openwifi.websocket.host.0.key
|
||||
This is a `pem` file that you will receive from Digicert for the gateway itself. The is the private key for the gateway.
|
||||
|
||||
###### openwifi.websocket.host.0.clientcas
|
||||
This is a `pem` file that contains both the issuer and the root CA certificates. You can find it You can find it [here](https://github.com/Telecominfraproject/wlan-cloud-ucentralgw/blob/main/certificates/clientcas.pem)
|
||||
|
||||
###### openwifi.websocket.host.0.cas
|
||||
This is a directory where you will copy your own `cert.pem`, the `root.pem`, and the `issuer.pem` files.
|
||||
|
||||
###### openwifi.websocket.host.0.address
|
||||
Leve this a `*` in teh case you want to bind to all interfaces on your gateway host or select the address of a single interface.
|
||||
|
||||
###### openwifi.websocket.host.0.port
|
||||
Leave to 15002 for now.
|
||||
|
||||
###### openwifi.websocket.host.0.security
|
||||
Leave this as strict for now for devices.
|
||||
|
||||
###### openwifi.websocket.host.0.key.password
|
||||
If you key file uses a password, please enter it here.
|
||||
|
||||
###### openwifi.websocket.maxreactors
|
||||
A single reactor can handle between 1000-2000 devices. Never leave this smaller than 5 or larger than 50.
|
||||
|
||||
#### Conclusion
|
||||
You will need to get the `cert.pem` and `key.pem` from Digicert. The rest is here.
|
||||
|
||||
###### host.0.address entries
|
||||
If you want to limit traffic to a specific interface, you should specify the IP address of that interface instead of
|
||||
the `*`. Using the `*` means all interfaces will be able to accept connections. You can add multiple interfaces
|
||||
by changing the `0` to another index. You need to repeat the whole configuration block for each index. Indexes must be sequential
|
||||
start at `0`.
|
||||
|
||||
```asm
|
||||
openwifi.service.key = $OWGW_ROOT/certs/websocket-key.pem
|
||||
```
|
||||
|
||||
#### Command line options
|
||||
The current implementation supports the following. If you use the built-in configuration file, you do not need to use any command-line
|
||||
options. However, you may decide to use the `--daemon` or `umask` options.
|
||||
|
||||
```bash
|
||||
./ucentralgw --help
|
||||
usage: ucentralgw OPTIONS
|
||||
A uCentral gateway implementation for TIP.
|
||||
|
||||
--daemon Run application as a daemon.
|
||||
--umask=mask Set the daemon's umask (octal, e.g. 027).
|
||||
--pidfile=path Write the process ID of the application to given file.
|
||||
--help display help information on command line arguments
|
||||
--file=file specify the configuration file
|
||||
--debug to run in debug, set to true
|
||||
--logs=dir specify the log directory and file (i.e. dir/file.log)
|
||||
```
|
||||
|
||||
##### file
|
||||
This allows you to point to another file without specifying the UCENTRALGW_CONFIG variable. The file name must end in `.properties`.
|
||||
##### daemon
|
||||
Run this as a UNIX service
|
||||
##### pidfile
|
||||
When running as a daemon, the pid of the running service will be set in the speficied file
|
||||
##### debug
|
||||
Run the service in debug mode.
|
||||
##### logs
|
||||
Speficy where logs should be kept. You must include an existing directory and a file name. For example `/var/ucentral/logs/log.0`.
|
||||
##### umask
|
||||
Seet the umask for the running service.
|
||||
|
||||
### ALB Support
|
||||
Support for AWS ALB is provided through the following configuration elements
|
||||
```asm
|
||||
alb.enable = true
|
||||
alb.port = 16102
|
||||
```
|
||||
|
||||
## Kafka integration
|
||||
So what about Kafka? Well, the gateway has basic integration with Kafka. It is turned off by default, to turn it on, in the configuration:
|
||||
|
||||
```asm
|
||||
openwifi.kafka.group.id = hello_world
|
||||
openwifi.kafka.client.id = hello_world1
|
||||
openwifi.kafka.enable = false
|
||||
openwifi.kafka.brokerlist = 127.0.0.1:9092
|
||||
openwifi.kafka.commit = false
|
||||
openwifi.kafka.queue.buffering.max.ms = 50
|
||||
```
|
||||
#### `openwifi.kafka.group.id`
|
||||
This must be set to your service's name and should be unique
|
||||
|
||||
#### `openwifi.kafka.client.id`
|
||||
This must be set to your service's name and should be unique
|
||||
|
||||
#### `openwifi.kafka.enable`
|
||||
Kind of obvious but hey, set `true` or `false`. Default is `false`
|
||||
|
||||
#### `openwifi.kafka.brokerlist`
|
||||
This is a comma separator list of the brokers in your `kafka` deployment.
|
||||
|
||||
#### Kafka topics
|
||||
Toe read more about Kafka, follow the [document](https://github.com/Telecominfraproject/wlan-cloud-ucentralgw/blob/main/KAFKA.md)
|
||||
|
||||
#### Securing `kafka`
|
||||
This is beyond the scope of this document. As it stands today, the communication between the gateway and `kafka` is expected to be behind a firewall.
