Introduction

In this tutorial we learn how to install procServ on CentOS 8.

What is procServ

procServ is a wrapper that starts an arbitrary command as a child process in the background, connecting its standard input and output to a Unix domain socket or a TCP port for telnet access. It supports logging, child restart (manual or automatic on exit), and more. procServ does not have the rich feature set of the screen utility, but is intended to provide running a command in a system service style, in a small, robust way. Handling multiple users, authorization, authentication, central logging is done best on a higher level, using a package like conserver. For security reasons, procServ only accepts connections from localhost.
