service

The service command is no longer valid in red hat based systems such as CentOS and Scientific Linux. You will probably see the message “Redirecting to /bin/systemctl” when you try and start / stop / status a service. So now we have to do it as below:

For example:

service httpd start

Would now be run as below:

systemctl start httpd

 

chkconfig

chkconfig has also been changed, for example:

chkconfig httpd on

becomes

systemctl enable httpd

… and …

chkconfig httpd off

becomes

systemctl disable httpd

… and …

chkconfig httpd

becomes

systemctl is-enabled httpd

… and …

The below command shows what services are enabled (chkconfig –list):

systemctl list-unit-files --type=service

 

Hope this helps someone!
