Full node ya Zebra iliyolindwa
- Hutumia mtumiaji maalumu asiye na mapendeleo + uwekeaji katika sandbox wa systemd katika kiwango cha kernel (utengaji sawa na Docker).
- RPC inapatikana localhost pekee kwa uthibitishaji salama wa cookie (chaguo-msingi na unaopendekezwa).
Mahitaji ya awali
- Usambazaji wowote unaotegemea Ubuntu
- Toolchain ya Rust imesakinishwa (
rustup + cargo)
- Angalau GB 300 za nafasi huru ya diski (sehemu ya
/var)
Usanidi wa mara moja (Tekeleza kama mtumiaji wako wa kawaida)
1. Sasisha mfumo na usakinishe vitegemezi vya ujenzi
Code-highlight
sudo apt update && sudo apt install -y build-essential pkg-config libclang-dev clang libssl-dev protobuf-compiler
Sasisha Rust na usakinishe zebrad ya karibuni zaidi (v4.3.0+)
Code-highlight
rustup update
cargo install --locked --force zebrad
sudo cp ~/.cargo/bin/zebrad /usr/local/bin/zebrad
sudo chown root:root /usr/local/bin/zebrad
sudo chmod 755 /usr/local/bin/zebrad
zebrad --version
Unda mtumiaji maalumu wa zebra asiye na mapendeleo
Code-highlight
sudo adduser --system --group --no-create-home --shell /usr/sbin/nologin zebra
Unda saraka salama ya data
Code-highlight
sudo mkdir -p /var/lib/zebrad
sudo chown zebra:zebra /var/lib/zebrad
sudo chmod 700 /var/lib/zebrad
Unda usanidi salama (/etc/zebrad/zebrad.toml)
Code-highlight
sudo mkdir -p /etc/zebrad
sudo tee /etc/zebrad/zebrad.toml > /dev/null <<EOF

sudo chown zebra:zebra /etc/zebrad/zebrad.toml
sudo chmod 600 /etc/zebrad/zebrad.toml
Unda huduma ya systemd iliyolindwa

Matumizi ya kila siku - Mtiririko wa kazi wa amri moja
| Kitendo | Amri | Maelezo |
|---|
| Anza | sudo systemctl start zebrad | Amri moja |
| Simamisha | sudo systemctl stop zebrad | Amri moja |
| Hali | sudo systemctl status zebrad | Huonyesha ikiwa inaendesha |
| Kumbukumbu za moja kwa moja | journalctl -u zebrad -f -o short-precise | Hubadilisha screen -r |
| Pata cookie ya RPC | sudo cat /var/lib/zebrad/.cookie | Wakati tu inaendesha |
Majina ya mkato ya urahisi (ongeza kwenye ~/.bashrc au ~/.zshrc):
