v2ray server setup tutorial

Get your server up to date:

1apt update && apt upgrade -y

Also install curl and socat:

1apt install curl socat -y

Install Acme Script

Download and install the Acme script for getting a free SSL certificate:

1curl https://get.acme.sh | sh

Get Free SSL Certificate

Set the default provider to Let’s Encrypt:

1~/.acme.sh/acme.sh –set-default-ca –server letsencrypt

Register your account for a free SSL certificate. In the next command, replace xxxx@xxxx.com by your actual email address:

1~/.acme.sh/acme.sh –register-account -m xxxx@xxxx.com

Obtain an SSL certificate. In the next command, replace host.mydomain.com by your actual host name:

1~/.acme.sh/acme.sh –issue -d host.mydomain.com –standalone

After a minute or so, the script terminates. On success, you will receive feedback as to the location of the certificate and key:

Your cert is in: /root/.acme.sh/host.mydomain.com/host.mydomain.com.cer
Your cert key is in: /root/.acme.sh/host.mydomain.com/host.mydomain.com.key
The intermediate CA cert is in: /root/.acme.sh/host.mydomain.com/ca.cer
And the full chain certs is there: /root/.acme.sh/host.mydomain.com/fullchain.cer

You cannot use the certificate and key in their current locations, as these may be temporary. Therefore install the certificate and key to a permanent location. In the next command, replace host.mydomain.com by your actual host name:

1~/.acme.sh/acme.sh –installcert -d host.mydomain.com –key-file /root/private.key –fullchain-file /root/cert.crt
Install certificate and key issued by Acme script

Run the X-UI Install Script

Download and run the one-click install script provided by the developer:

1bash <(curl -Ls https://raw.githubusercontent.com/vaxilu/x-ui/master/install.sh)

Common Panel Commands

From the command line, you can control the server with various commands:

x-ui uninstallUninstall X-UI panel

First Time Login

You can get to the X-UI panel on your PC by opening a browser and typing your server IP address and port 54321. For example:

1http://123.45.67.89:54321

By default, the login user name is admin, and the password is also admin.

Enable HTTPS on Panel

You will notice that, at first, you used plain text HTTP to reach the panel. This is not secure.

To enable HTTPS, choose 面板设置 (Panel settings).

You will need to specify your certificate and key.

Specifying certificate and key in X-UI panel settings

Save these options.

Now in your SSH session issue the command:

1x-ui restart

Now you can reach the panel using HTTPS. For example:

1https://host.mydomain.com:54321
HTTPS login to X-UI panel

Change Admin Password

The default admin user name admin and password admin are the same for all installations. This is not secure. Input the old values of admin and admin, and choose new, unique values:

ChineseEnglish
原用户名Original user name
原密码Old password
新用户名New user name
新密码New password
X-UI panel change user name and password

Save the new values.

Sign out, then sign in again with the new user name and password.

HTTPS login with new user name and password

Add VLESS+XTLS Xray User

We are going to add an inbound user account using VLESS and Xray. VLESS is an an updated version of the older Vmess protocol. After several developers found flaws in Vmess protocol and showed that the Vmess protocol can be detected by deep packet inspection or DPI, VLESS was developed. (Note that it is plain Vmess that can be detected; Vmess+WS+TLS is still secure and supports the use of a CDN.) Xray core was developed as an alternative to the older V2Ray core. According to the Xray developers, Xray is more stable, better for UDP gaming, and 30% faster than V2Ray. XTLS speeds up TLS by reducing double-encryption.

On the side menu, select 入站列表 (Inbound list).

Click the plus sign to add a new inbound user.

The 添加入站 (Add inbound) box appears.
