systemctl

To list  systemd services we will use systemctl command as below
# systemctl list-unit-files

To list active systemd services run
# systemctl | more

# systemctl list-units --type service

You can pipe the output to grep to search a more specific service as shown below
# systemctl | grep "apache2"

To check the services alongside the ports they are listening.
# netstat -pnltu

For example, to check if OpenSSH is running on your system, run
# systemctl status sshd

Alternatively, you can use the syntax below to check if the service is active
# systemctl is-active sshd

o check if OpenSSH is enabled, run
# systemctl is-enabled sshd

Ancien system:
check the status of OpenSSH, run
# service sshd status

You can also check all services by running
# chkconfig --list
