KB450166 – Listing Running Services in CentOS

To list the running services in your CentOS installation, there are several methods and tools that can be used. We suggest the following commands to meet this need:

Older versions of CentOS & Upstart:

service --status-all

List services and their open ports. This command can be important when you’re looking to do port forwarding or troubleshooting the network behavior of a unit:

netstat -tulpn

Systemd(user & root), these commands can be used to list every service, including those that are inactive. This will also list a description of each service.

systemctl -l --type service --all

systemctl -r --type service --all

Init.d:

/etc/init.d
