Warning

Breaking changes since 2026-10-18

Fresh installations can ignore this notice. When upgrading from older versions, follow these instructions to avoid Xray startup failures or reduced security.

1. Geodata: To address some known issues, the data source has changed from Loyalsoldier/v2ray-rules-dat to XTLS/Xray-rules-dat. Full compatibility with the previous data is not guaranteed. If you need GeoIP country categories other than cn, ru, and ir, run update-geodata (renamed from install-geodata). If you need special GeoSite categories provided by Loyalsoldier, such as gfw or win-spy, manually download Loyalsoldier's geosite.dat, save it as geosite-loyalsoldier.dat in the asset directory, and use ext:geosite-loyalsoldier.dat:category in your Xray configuration.

2. Log rotation: Use the --logrotate option provided by this installer. Do not configure additional rotation tasks, as they may cause permission or log writing issues.

3. File permissions: In response to the recent wave of 0day vulnerabilities in other software and system components, this installer strengthens service isolation and file permission controls to limit their potential impact on Xray. Services now run under the dedicated xray user instead of the shared nobody account. Custom runtime users are no longer supported, and permissions on configuration and log directories have been tightened. Check access permissions for your custom configuration files, certificates, and existing installations.

   Expand to view default permissions and requirements for custom configurations and certificates

   The table below shows the secure default permissions automatically set by the current installer. The program and configuration are managed by root, and the xray account can only read the configuration; the service can write geodata and logs. These settings protect logs and configuration files and follow security best practices.

   Purpose	Path	Owner:Group	Permissions
   Xray binary	/usr/local/bin/xray	root:root	0755
   Configuration directory	/usr/local/etc/xray/	root:xray	0750
   Configuration files	/usr/local/etc/xray/*.json	root:xray	0640
   Geodata directory	/usr/local/share/xray/	xray:xray	0755
   GeoIP data	/usr/local/share/xray/geoip.dat	xray:xray	0644
   GeoSite data	/usr/local/share/xray/geosite.dat	xray:xray	0644
   Log directory	/var/log/xray/	xray:xray	0700

   Directory and file permissions from older installations are not automatically migrated. Adjust them manually according to the table above. Alternatively, back up your configuration and data, completely uninstall the older version and delete all related directories and files, then reinstall.

   Custom configurations and certificates (if any): Your custom configuration directories, new configuration files, certificate directories, certificates, and private keys should also follow the permission rules for "Configuration directory" and "Configuration files" in the table above.

Filesystem Hierarchy Standard (FHS)

installed: /etc/systemd/system/xray.service
installed: /etc/systemd/system/xray@.service

installed: /usr/local/bin/xray
installed: /usr/local/etc/xray/*.json

installed: /usr/local/share/xray/geoip.dat
installed: /usr/local/share/xray/geosite.dat

installed: /var/log/xray/

Notice: Xray will NOT log to /var/log/xray/*.log by default. Configure "log" to specify log files.

Basic Usage

Install & Upgrade Xray-core

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install

Update geoip.dat and geosite.dat only

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ update-geodata

Xray bundles GeoIP lite and GeoSite standard; this command downloads GeoIP full and GeoSite expanded. Data comes from XTLS/Xray-rules-dat.

Remove Xray, except json and logs

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ remove

Check for updates

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ check

Install from a local archive (alternative)

Download the installation script and the Xray-core zip for your architecture, then run as root (x86_64 example):

bash install-release.sh install --local ./Xray-linux-64.zip

Use --geoip and --geosite independently to supply local data; omitted options use the bundled data.

Advance

Install or upgrade through a proxy

bash -c "$(curl -x http://127.0.0.1:8118 -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install --proxy http://127.0.0.1:8118

--proxy supports HTTP and SOCKS proxies and also applies to update-geodata and check.

Install & Upgrade Xray-core to a pre-release version

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install --beta

Install & Upgrade Xray-core with logrotate, $time can be in the format of 12:34:56

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install --logrotate $time

installed: /etc/systemd/system/logrotate@.service
installed: /etc/systemd/system/logrotate@.timer

installed: /etc/logrotate.d/xray

Install & Upgrade Xray-core without geodata

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install --without-geodata

Remove Xray, include json and logs

bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ remove --purge

Other options

install also accepts:

Option	Description
--version <version>	Install a specified version.
--force	Force installation.
--reinstall	Reinstall the current version.
--no-update-service	Keep existing service files.
--without-logfiles	Skip creating the log directory.

Multiple instances

Set JSONS_PATH when installing to use configuration directories:

JSONS_PATH=/usr/local/etc/xray bash install-release.sh install

xray.service reads JSONS_PATH; xray@a.service reads JSONS_PATH/a/. Put each instance's configuration files in its directory, then start it with systemctl enable --now xray@a.
