Installing
1
dnf install -y OpenIPMI ipmitool
To enable and run

/sbin/chkconfig ipmi on
service ipmi start
Configuring
1) Make sure to run as root or sudo 2) Run these commands to enable the drivers

/sbin/modprobe ipmi_msghandler
/sbin/modprobe ipmi_si
/sbin/modprobe ipmi_devintf
3) Optional, run /sbin/lsmod | grep ipmi to confirm that the IPMI modules have been loaded.
4) To make sure the modules are loaded on system reboot, edit /etc/rc.local and enter in the following:

3
/sbin/modprobe ipmi_msghandler
/sbin/modprobe ipmi_si
/sbin/modprobe ipmi_devintf
5) Make sure that the Linux machine sees the IPMI device ls -l /dev/ipmi0.
If an output is returned, great. If not, than the udevd daemon isn’t setup to create device files automatically and you must manually create the device.
1) Determine what the device major number is for the IPMI device grep ipmi /proc/devices.
2) The output will be similar to 253 ipmidev. The device’s major number is 253.
3) Run mknod /dev/ipmi0 c 253 0x0 to create an entry for the device using the major number. This major number can change per system.
