What is V2Ray?

V2Ray is a software tool that helps you maintain your online privacy and security while browsing the internet. It acts as a “middleman” between your device and the websites you visit. When you use V2Ray, it encrypts your internet connection, making it difficult for others to spy on your online activities or steal your personal information. It also allows you to bypass internet restrictions and access blocked websites or services. In simple terms, V2Ray is like a protective shield that keeps you safe and allows you to explore the internet freely and privately.

Requirements to Install V2Ray on CentOS

Although setting up V2Ray on your CentOS server is not a hard job, there are a few prerequisites that you need to ensure are met:

  • Linux VPS Server with CentOS OS: Make sure you have a CentOS server or a Linux VPS. They should have root access or a user with sudo privileges.
  • Internet connection: Ensure that your server has a stable internet connection to download the necessary files.
  • Basic command-line knowledge: Familiarize yourself with basic command-line operations as you will need to execute commands to install and configure V2Ray.
  • Firewall configuration: If you have a firewall enabled on your CentOS server, you may need to configure it to allow V2Ray traffic.

By ensuring these requirements are met, you will be ready to proceed with the setup of V2Ray on CentOS.

Requirements to setup V2Ray on CentOS

Setup V2Ray on CentOS

  • First, you should update your CentOS system. Open a terminal or SSH into your CentOS server and run the following command to update the system:
     sudo yum update
  • Download the latest release of V2Ray by visiting the official GitHub repository. Identify the appropriate package for your CentOS system (e.g., 64-bit or 32-bit). Copy the download link of the package. In the terminal, use the `wget` command followed by the download link to download the package. For example:
     wget <download_link>

Once the download is complete, extract the package using the following command:

     tar -xvf <package_name>.tar.gz

Navigate to the extracted directory:

     cd v2ray-<version_number>-linux-<architecture>

Move the V2Ray executable to `/usr/local/bin`:

     sudo mv v2ray /usr/local/bin/
     sudo mv v2ctl /usr/local/bin/
  • Create a new configuration file for V2Ray:
     sudo nano /etc/v2ray/config.json

Copy and paste the sample configuration provided by V2Ray into the `config.json` file. Customize the configuration according to your needs, such as changing the listening port or adding inbound and outbound proxies, then save and exit the configuration file.

  • Create a new systemd service file for V2Ray:
     sudo nano /etc/systemd/system/v2ray.service

Copy and paste the following content into the `v2ray.service` file:

     Description=V2Ray Service

     ExecStart=/usr/local/bin/v2ray -config /etc/v2ray/config.json


Save and exit the service file. Enable and start the V2Ray service:

     sudo systemctl start v2ray     
     sudo systemctl enable v2ray
  • Check the status of the V2Ray service to ensure it is running without any errors:
     sudo systemctl status v2ray

That’s it! You have now successfully set up V2Ray on CentOS. You can proceed to configure your client devices to connect to the V2Ray server using the specified settings in the `config.json` file.

Troubleshoot Common Issues

While setting up V2Ray on CentOS, you might face some problems. We’ve listed them for you and we have a short solution for each.

  • Firewall blocking connections: Check if the firewall is blocking the required ports (e.g., 80, 443). Temporarily disable the firewall or allow incoming connections on the necessary ports using the firewall-cmd command.
  • Port conflicts: Ensure that the ports specified in the V2Ray configuration file are not being used by other services. Use the netstat command to check if any other processes are using the specified ports.
  • SELinux blocking V2Ray: If SELinux is enforced, it might stop V2Ray from functioning correctly. Temporarily set SELinux to permissive mode using the setenforce command (e.g., setenforce 0) and check if the issue persists. If it does, consider properly configuring SELinux policies.
  • Incorrect V2Ray configuration: Verify the V2Ray configuration file (/etc/v2ray/config.json) for any syntax errors or missing/wrong settings. Use the v2ray -test -config command to validate the configuration file.
  • Network connectivity issues: Test the connectivity by pinging external servers or performing a traceroute. Verify DNS configuration in /etc/resolv.conf and ensure it is resolving domain names correctly.
