V2Ray One-Click Installation Script for Secure Internet Access

This V2Ray one-click script supports IPv6-only servers, but it’s not recommended to use an IPv6-only VPS for bypassing internet restrictions.

After completing the prerequisites, run the following command to install the V2Ray all-in-one script (copy and paste recommended):

bash <(curl -sL https://sunqi.org/v2ray.sh)

After pressing Enter, you’ll see the following menu:
1. Install V2ray-VMESS
2. Install V2ray-VMESS+mKCP
3. Install V2ray-VMESS+TCP+TLS
4. Install V2ray-VMESS+WS+TLS (Recommended)
5. Install V2ray-VLESS+mKCP
6. Install V2ray-VLESS+TCP+TLS
7. Install V2ray-VLESS+WS+TLS (CDN compatible)
8. Install V2ray-VLESS+TCP+XTLS (Recommended)
9. Install trojan (Recommended)
10. Install trojan+XTLS (Recommended)

If the menu doesn’t appear after pressing Enter:

For CentOS systems, run:

yum install -y curl

For Ubuntu/Debian systems, run:

sudo apt install -y curl

Then run the installation command again.

Now choose according to your needs. For this tutorial, we’ll select option “8” to install “V2ray-VLESS+TCP+XTLS”.

After pressing Enter, you might see:

Before running the V2ray one-click script, please confirm the following:
1. A fake domain name
2. The fake domain’s DNS resolves to the current server IP (192.168.0.1)
3. If you have v2ray.pem and v2ray.key certificate files in /root, condition 2 can be ignored

Press y to confirm, any other key to exit:

Once you’ve confirmed the domain resolution or have the certificate files (trojan-go.pem and trojan-go.key in /root), press “y” to proceed with installation.

The installation process will then begin.

1. During installation, you’ll be prompted to enter some information (enter as needed, or press Enter to use defaults).
2. Please be patient during the script installation. If the screen freezes, do nothing as long as the SSH connection remains active.
3. If the SSH connection drops, simply re-run the installation command to continue.

Once the script finishes, you’ll see the following information screen:

V2Ray is now installed. The SSH window will display the configuration details:

• Protocol
• IP (address)
• Port
• ID (UUID)
• Flow control
• Encryption
• Transport protocol (network)
• Fake domain (host)
• TLS

Your V2Ray all-in-one one-click installation is now complete.

After installation, the VPS may or may not reboot automatically — this is normal.

If you installed the VLESS or VMESS+WS+TLS combination, open your browser and enter your fake domain. If the fake website loads correctly, the server is configured properly.

V2Ray One-Click Script Notes

1. If you plan to use a CDN like CloudFlare for proxying, you must install the WS version of the V2Ray script.
2. This V2Ray one-click script includes BBR acceleration by default — no need to install it separately.
3. If the script doesn’t include a fake website you like, you can set up your own WordPress blog. See: V2ray Fake Website Tutorial.
4. For TLS-based installations, the script automatically obtains domain certificates, stored in the same folder as the V2Ray config file (/etc/v2ray). Certificates auto-renew. If your client suddenly stops working, check if the fake website loads. If the certificate has expired, re-run the script to reconfigure.
5. Avoid using excessive traffic immediately after setting up V2Ray, as this may lead to VPS throttling, port blocking, or even IP blacklisting.
