### Getting MongoDB
|
|
---
|
|
|
|
Install MongoDB with package manager.
|
|
```bash
|
|
$ sudo apk update
|
|
$ sudo apk add mongodb
|
|
```
|
|
|
|
Run MongoDB server.
|
|
```bash
|
|
$ mkdir -p ./data/db
|
|
$ mongod --dbpath ./data/db
|
|
```

### Setting up TUN device (No persistent after rebooting)
|
|
---
|
|
|
|
Create the TUN device. Interface name will be `ogstun`.
|
|
```bash
|
|
$ sudo apk add iproute2
|
|
$ sudo ip tuntap add name ogstun mode tun
|
|
$ ip link show
|
|
```
|
|
|
|
You are now ready to set the IP address on TUN device.
|
|
|
|
```bash
|
|
$ sudo ip addr add 10.45.0.1/16 dev ogstun
|
|
$ sudo ip addr add 2001:db8:cafe::1/48 dev ogstun
|
|
```
|
|
|
|
Make sure it is set up properly.
|
|
```bash
|
|
$ sudo ip link set ogstun up
|
|
$ ip link show
|
|
```
|
|
|
|
**Tip:** The script provided in [$GIT_REPO/misc/netconf.sh](https://github.com/{{ site.github_username }}/open5gs/blob/main/misc/netconf.sh) makes it easy to configure the TUN device as follows:
|
|
`$ sudo ./misc/netconf.sh`

### Building Open5GS
|
|
---
|
|
|
|
Install the depedencies for building the source code.
|
|
```bash
|
|
$ sudo apk add alpine-sdk bison flex git cmake meson bash sudo linux-headers bsd-compat-headers yaml-dev lksctp-tools-dev gnutls-dev libgcrypt-dev libidn-dev mongo-c-driver-dev libmicrohttpd-dev curl-dev nghttp2-dev talloc-dev
|
|
```
|
|
|
|
Git clone.
|
|
|
|
```bash
|
|
$ git clone https://github.com/{{ site.github_username }}/open5gs
|
|
```
|
|
|
|
To compile with meson:
|
|
|
|
```bash
|
|
$ cd open5gs
|
|
$ meson build --prefix=`pwd`/install
|
|
$ ninja -C build
|
|
```
|
|
|
|
Check whether the compilation is correct.
|
|
```bash
|
|
$ ./build/tests/attach/attach ## EPC Only
|
|
$ ./build/tests/registration/registration ## 5G Core Only
|
|
```
|
|
|
|
Run all test programs as below.
|
|
```bash
|
|
$ cd build
|
|
$ meson test -v
|
|
```
|
|
|
|
**Tip:** You can also check the result of `ninja -C build test` with a tool that captures packets. If you are running `wireshark`, select the `loopback` interface and set FILTER to `s1ap || gtpv2 || pfcp || diameter || gtp || ngap || http2.data.data || http2.headers`. You can see the virtually created packets. [testattach.pcapng]({{ site.url }}{{ site.baseurl }}/assets/pcapng/testattach.pcapng)/[testregistration.pcapng]({{ site.url }}{{ site.baseurl }}/assets/pcapng/testregistration.pcapng)
|
|
{: .notice--info}
|
|
|
|
You need to perform the **installation process**.
|
|
```bash
|
|
$ cd build
|
|
$ ninja install
|
|
$ cd ../
|
|
```
|

### Building WebUI of Open5GS
|
|
---
|
|
|
|
[Node.js](https://nodejs.org/) is required to build WebUI of Open5GS
|
|
|
|
```bash
|
|
$ sudo apk add nodejs
|
|
```
|
|
|
|
Install the dependencies to run WebUI
|
|
|
|
```bash
|
|
$ cd webui
|
|
$ npm ci
|
|
```
|
|
|
|
The WebUI runs as an [npm](https://www.npmjs.com/) script.
|
|
|
|
```bash
|
|
$ npm run dev
|
|
```
