+
+## Tutoriál nebo něco
+
+Pravděpodobně to běží jenom na Linuxu, ale nikdo na serverech Windows stejně nepoužívá. Tutoriál počítá se systémem Ubuntu a je možné, že je nekompletní.
+
+### Nainstaluj Rust
+
+Ne, nejsem transka (zatím).
+
+```
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+### Nainstaluj ostatní požadavky
+
+```
+# Potřebné ke kompilaci
+sudo apt install binutils build-essential libssl-dev libpq-dev postgresql
+# Potřebné k funkci
+sudo apt install imagemagick ffmpeg
+```
+
+### Vytvoř databázi
+
+```
+sudo adduser nekrochan --system --disabled-login --no-create-home --group
+sudo passwd nekrochan # Nastavíme heslo pro systémového uživatele
+sudo -iu postgres psql -c "CREATE USER nekrochan WITH PASSWORD 'password';"
+sudo -iu postgres psql -c "CREATE DATABASE nekrochan WITH OWNER nekrochan;"
+```
+
+### Automatická konfigurace
+
+```
+chmod +x ./configure.sh
+./configure.sh
+```
+
+### Nastartuj server
+
+```
+cargo run --release
+```
+
+### Vytvoř nástěnku
+
+Po kompilaci by se měl spustit server na https://localhost:7000/. Stránka ti pravděpodobně řekne, že ještě nebyla inicializována domovní stránka. Je potřeba vytvořit nástěnku. Nejdříve je ale potřeba vytvořit administátorský účet.
+
+Heslo v příkladu je "password", můžeš použít příklad a heslo změnit potom v administrátorském rozhraní.
+
+```
+sudo -iu nekrochan psql -c "INSERT INTO accounts (username, password, owner, permissions) VALUES ('admin', '$2y$10$jHl27pbYNvgpQxksmF.N/O0IHrfFBDY1Tg/qBX/UwrMa3j7owkiQm', true, '131072'::jsonb);"
+```
+
+Po příkazu budeš muset restartovat server, aby se změna projevila v mezipaměti.
+
+Nástěnka lze vytvořit po přihlášení na https://localhost:7000/login na stránce https://localhost:7000/staff/boards
+
+### Automatický start
+
+Nejprve vytvoříme složku pro nekrochan a zkopírujeme tam potřebné soubory.
+
+```
+sudo mkdir -p /srv/nekrochan
+sudo chown nekrochan:nekrochan /srv/nekrochan
+sudo cp -r ./target/release/nekrochan Nekrochan.toml ./pages ./static ./uploads /srv/nekrochan/
+```
+
+Nyní vytvoříme skript pro systemd, aby server automaticky nastartovat po zapnutí počítače. Uložíme ho jako `/etc/systemd/system/nekrochan.service`.
+
+```
+[Unit]
+Description=Nekrochan
+After=network.target
+
+[Service]
+User=nekrochan
+ExecStart=/srv/nekrochan/nekrochan
+WorkingDirectory=/srv/nekrochan
+Environment=RUST_LOG="info"
+Restart=on-failure
+
+ProtectSystem=yes
+PrivateTmp=true
+MemoryDenyWriteExecute=true
+NoNewPrivileges=true
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### Další konfigurace
+
+Většinu možností najdeš v souboru `Nekrochan.toml`. Vlastní stránky (např. pravidla, faq apod.) můžeš nahrávat do složky `pages`.
+
+Také budeš pravděpodobně chtít nastavit reverzní proxy, např. NGINX. IP adresu posílej serveru v hlavičce `X-Forwarded-For` a kód země (potřebný pro vlajky) v hlavičce `X-Country-Code`.
