Check If A Service Is Running Or Not

How do I find out if a service such as MySQL or Apache running on my Centos/RHEL/Fedora Linux Server?

# Service servername status

# service named status

# Service mysqld status

Find out status of all services

The service --status-all command runs all init scripts, in alphabetical order, with the status command:
 
# Service --status-all
