Installation

Step 1 — download the script

wget -qO x-ui-latest.sh https://raw.githubusercontent.com/mozaroc/3x-ui-pro/main/x-ui-latest.sh

Step 2 — run it

bash x-ui-latest.sh -install y

Patch

Apply current fixes to an existing installation (no DB changes):

bash <(curl -fsSL https://raw.githubusercontent.com/mozaroc/3x-ui-pro/main/x-ui-patch.sh)

AdGuard Home (optional)

Installs AdGuard Home on the panel domain — no separate domain or open ports, everything goes through the existing 443:

DNS-over-HTTPS for clients: https://<panel-domain>/dns-query
Admin UI — at a random /adg-<random>/ path (login and password are printed by the script)

bash <(curl -fsSL https://raw.githubusercontent.com/mozaroc/3x-ui-pro/main/x-ui-adguard.sh)

Re-running is safe (settings and password are kept). After the installer or the patch, run this script again — they rewrite the nginx config.

Uninstall:

bash <(curl -fsSL https://raw.githubusercontent.com/mozaroc/3x-ui-pro/main/x-ui-adguard.sh) -uninstall y

Uninstall

bash x-ui-latest.sh -uninstall y

Command-line options

Option	Description
`-install y`	Install
`-subdomain <domain>`	Panel and subscription domain
`-reality_domain <domain>`	REALITY destination domain
`-auto_domain y`	Auto-detect domain (no manual input)
`-version <version>`	Install specific 3x-ui version (e.g. `3.4.2`), default — latest
`-uninstall y`	Full uninstall

Clash subscription

Works via User-Agent detection — one URL, different behavior:

Clash / Mihomo / Stash → get a ready-to-use clash.yaml config
Regular browser / other clients → get the standard 3x-ui subscription page

The import link is printed by the script after installation.

Backup and restore

wget -qO /usr/local/bin/x-ui-backup https://raw.githubusercontent.com/mozaroc/3x-ui-pro/main/assets/backup/x-ui-backup.sh
