Use any one of:

/etc/init.d/<service> restart

/etc/init.d/<service> stop && /etc/init.d/<service> start

service <service> restart

Since the location of startup scripts varies from distro to distro, using the service command is recommended.

Show all the services for every runlevel:

chkconfig --list

Enable a service (eg: sshd) on runlevels 2, 3, 4:

chkconfig --add sshd
chkconfig --level 234 sshd on

systemctl start 
systemctl stop

systemctl status

Similar to linux, you can either start services using their startup scripts or using the service command.

Usually, the startup scripts are located in /etc/rc.d

/etc/rc.d/<service> restart

However, if it is 3rd party software, they are located in /usr/local/etc/rc.d

/usr/local/etc/rc.d/<service> restart

Or to not worry about any of the above, use service

service nfs stop
service sickbeard start
service httpd status

Note: You can send the HUP signal to restart a service. For instance, to restart NFS, you can do any one of:

kill -HUP `cat /var/run/mountd.pid`
/etc/rc.d/nsfd restart
service nfs restart

The startup scripts are located in /lib/svc/method/<service>

/lib/svc/method/<service> restart
svcadm restart <service>

Example: To restart ssh, do any one of:

svcadm restart ssh

svcadm restart svc:/network/ssh

/lib/svc/method/sshd restart
