How to Use a Run Control Script to Stop or Start a Legacy Service

One advantage of having individual scripts for each run level is that you can run scripts in the /etc/init.d directory individually to stop system services without changing a system's run level.

1. Become superuser or assume an equivalent role.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

2. Stop the system service.

   # /etc/init.d/filename stop

3. Restart the system service.

   # /etc/init.d/filename start

4. Verify that the service has been stopped or started.

   # pgrep -f service

For example, you can stop the NFS server daemons by typing the following:

# /etc/init.d/nfs.server stop
# pgrep -f nfs

Then, you can restart the NFS server daemons by typing the following:

# /etc/init.d/nfs.server start
# pgrep -f nfs
