### Getting MongoDB
|
|
---
|
|
|
|
Create the MongoDB repository file.
|
|
```bash
|
|
$ sudo sh -c 'cat << EOF > /etc/yum.repos.d/mongodb-org-3.4.repo
|
|
[mongodb-org-3.4]
|
|
name=MongoDB Repository
|
|
baseurl=https://repo.mongodb.org/yum/redhat/\$releasever/mongodb-org/3.4/x86_64/
|
|
gpgcheck=1
|
|
enabled=1
|
|
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc
|
|
EOF'
|
|
```
|
|
|
|
Install MongoDB with Package Manager.
|
|
```bash
|
|
sudo dnf -y install mongodb-org
|
|
```
|
|
|
|
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 yum -y install iproute
|
|
$ sudo ip tuntap add name ogstun mode tun
|
|
$ ip link show
|
|
```
|
|
|
|
Then, to support IPv6-enabled UEs, you must configure your TUN device to support IPv6.
|
|
|
|
```bash
|
|
$ sysctl -n net.ipv6.conf.ogstun.disable_ipv6
|
|
1
|
|
|
|
$ sudo -w net.ipv6.conf.ogstun.disable_ipv6=0
|
|
|
|
$ sysctl -n net.ipv6.conf.ogstun.disable_ipv6
|
|
0
|
|
```
|
|
|
|
**Note:** If your TUN device already supports IPv6, you can skip this steps above.
|
|
{: .notice--warning}
|
|
|
|
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 cafe::1/64 dev ogstun
|
|
```
|
|
|
|
Make sure it is set up properly.
|
|
```bash
|
|
$ sudo ip link set ogstun up
|
|
$ ip link show
|
|
```
|
|
|
|
**Tip:** The script provided in [$GIT_REPO/misc/netconf.sh](https://github.com/{{ site.github_username }}/open5gs/blob/master/misc/netconf.sh) makes it easy to configure the TUN device as follows:
|
|
`$ sudo ./misc/netconf.sh`
|
|

### Building Open5GS
|
|
---
|
|
|
|
Configure EPEL package.
|
|
|
|
```bash
|
|
$ sudo dnf install epel-release
|
|
```
|
|
|
|
Enable PowerTools.
|
|
```bash
|
|
$ sudo dnf install 'dnf-command(config-manager)'
|
|
$ sudo dnf config-manager --set-enabled PowerTools
|
|
$ sudo update
|
|
```
|
|
|
|
Configure ELRepo(with testing) package.
|
|
```bash
|
|
$ sudo dnf install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
|
|
$ sudo dnf config-manager --set-enabled elrepo-testing
|
|
$ sudo dnf update
|
|
```
|
|
|
|
Install the depedencies for building the source code.
|
|
```bash
|
|
$ sudo dnf install python3 ninja-build gcc flex bison git lksctp-tools-devel libidn-devel gnutls-devel libgcrypt-devel openssl-devel cyrus-sasl-devel libyaml-devel mongo-c-driver-devel libmicrohttpd-devel libcurl-devel iproute
|
|
```
|
|
|
|
Install Meson
|
|
```bash
|
|
$ sudo dnf install meson
|
|
```
|
|
|
|
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 || http`. 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
|
|
$ curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
|
|
$ sudo yum -y install nodejs
|
|
```
|
|
|
|
Install the dependencies to run WebUI
|
|
|
|
```bash
|
|
$ cd webui
|
|
$ npm install
|
|
```
|
|
|
|
The WebUI runs as an [npm](https://www.npmjs.com/) script.
|
|
|
|
```bash
|
|
$ npm run dev
|
|
```
