CentOS5 Host One-Click VPN Installation Tutorial

There are many configuration tutorials online, but they are all manual, and the configuration is very complex. Unless you have professional technical skills, you won't be able to operate them, and even if you do, you'll likely make many mistakes. This environment is CentOS 5 32-bit; I haven't tested other environments yet.

This tutorial is a one-click installation guide. If you prefer manual installation, please refer to: CentOS 6.5 VPN Setup Tutorial. Feel free to leave a message if you have any questions.

The first step is to configure the VPS environment.

We log in to the VPS host using SSH, and then download and install it using the one-click installation script below.

wget http://myvps-scripts.googlecode.com/files/pptpd.sh sh pptpd.sh

The second step is to wait for the installation to complete.

If you've ever tried manual installation, you'll find it very complicated. But with a one-click installation package, you only need to wait a few tens of seconds, and seeing the interface below means the installation is complete.

The interface shown above indicates that we have successfully installed the software. The displayed information includes the IP address, login type, default username, and password.

The third step is to modify and add accounts.

Since the default password might not be what we like, we might prefer to use our own frequently used username and password, or even create a separate account for others to use. In this case, we can go to the following file directory.

/etc/ppp/chap-secrets

You can log in via FTP, or open the file using the `vi /etc/ppp/chap-secrets` script;

This way we can add a row of accounts that we are familiar with.

In summary, setting up a VPN account on a dedicated VPS can be easily accomplished through the three steps outlined above. Traditional tutorials might have taken half a day to complete this, but now we can do it in just 3 minutes, saving us a lot of time and improving efficiency. It's worth noting that VPSs should ideally be Xen-based; OVZ may not support PPP and TUN, so Xen-based technologies are recommended.
