How Do I Access VMs on a BMS with KVM Deployed from the Internet?

Solution

You can install the port mapping software rinetd on a Linux BMS so that you can access VMs deployed on the BMS from the Internet. Take CentOS 7 as an example. Perform the following steps:

1. Download the rinetd installation package from the following path and upload it to the BMS:

   https://codeload.github.com/boutell/rinetd/zip/refs/heads/master

2. Run the following commands to install rinetd:

   # Installation dependencies

   yum -y install gcc gcc-c++

   unzip rinetd-master.zip

   mkdir -p /usr/man/man8

   cd rinetd-master/

   make

   make install

3. Run the following command to add the port mapping rule to the configuration file:

   vi /etc/rinetd.conf

   The following is an example: Local IP address Local port VM internal IP address VM port

   0.0.0.0 22222 192.168.124.81 22

4. Run the following command to start the rinetd process:

   /usr/sbin/rinetd

5. Run the following command to connect to port 22222 corresponding to the BMS using SSH to access the VMs from the Internet:

   ssh BMS EIP:22222
