Grid 188.8.131.52 Install fails when running root.sh on OL7, this affects both Oracle Clusterware and Oracle Restart Installation.
rootcrs.log/roothas.log confirms that ohasd/crsd failed to start
There is a known issue where OL7 expects to use systemd rather than initd for running processes and restarting them and root.sh does not handle this currently.
This was reported in the following Unpublished Bug
Bug 18370031 - RC SCRIPTS (/ETC/RC.D/RC.* , /ETC/INIT.D/* ) ON OL7 FOR LUSTERWARE
Because Oracle Linux 7 (and Redhat 7) use systemd rather than initd for starting/restarting processes and runs them as a service the current software install of both 184.108.40.206 & 220.127.116.11 will not succeed because the ohasd process does not start properly.
In OL7 it needs to be set up as a service and patch fix for Bug 18370031 needs to be applied for this , BEFORE you run root.sh when prompted .
Need to apply the patch 18370031 for 18.104.22.168 .
And also its mentioned in 11gR2 Release Notes:https://docs.oracle.com/cd/E11882_01/relnotes.112/e23558/toc.htm#CJAJEBGG
During the Oracle Grid Infrastructure installation, you must apply patch 18370031 before configuring the software that is installed.
The timing of applying the patch is important and is described in detail in the Note 1951613.1 on My Oracle Support. This patch ensures that
the clusterware stack is configured to use systemd for clusterware processes, as Oracle Linux 7 uses systemd for all services.
