Linux7安装gi报错,Redhat 7.6安装11G RAC GI时遇到此类报错
环境：Redhat Linux 7.6 + Oracle 11.2.0.4 RAC
现象：图像化安装过程中，按照提示执行root.sh脚本，报错中断。
1. 具体现象
[root@mm1903 ~]# /u01/app/11.2.0/grid/root.sh
Performing rootuser operation forOracle 11g

ORACLE_OWNER=grid
ORACLE_HOME= /u01/app/11.2.0/grid

The contentsof "dbhome" have not changed. No need tooverwrite.
The contentsof "oraenv" have not changed. No need tooverwrite.

Redhat 7.6搭建11g RAC时遇到报错：
[ohasd(15204)]CRS-0715:Oracle High Availability Service has timed out waiting for init.ohasd to be started.
2. 定位问题
官方文档：
Install of Clusterware fails while running root.sh on OL7 - ohasd fails to start (Doc ID 1959008.1)
由此篇官方文档可知，致使root.sh脚本执行时报的原因是因为Linux 7与Linux 6启动/重新启动进程并将其作为服务运行的方式不同。
Linux 6是由initd启动进程，而Linux 7则是由systemd启动进程。
在11.2.0.4 & 12.1.0.1安装GI时，无法加载集群资源进程，所以不会成功。
若想要在Linux 7上运行此两个版本GI软件，需要应用补丁程序18370031。
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 11.2.0.4 & 12.1.0.1 will not succeed because the ohasd process does notstart 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 .
3. 解决问题
此外还有中简单有效的解决方法，也是永久性的：
修改ohasd守护进程文件 vi /etc/init.d/ohasd
在文件中找到如这部分，在里面添加标注部分：
————————————————if [-r $AUTOSTARTFILE]
then
case `$CAT $AUTOSTARTFILE` inenable*)
$LOGERR "Oracle HA daemonis enabled forautostart."/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 & ---标注
my_crsctl start has -nowait
sleep600 ---标注
ps -ef | grep dd| grep hasd|awk '{print $2}'|xargs kill -9 ---标注
;;
disable*)
$LOGERR "Oracle HA daemonis disabled forautostart."
;;*)
$LOGERR "Oracle HA daemonis disabled bydamaged install."
$LOGERR "Unexpected settings foundin$AUTOSTARTFILE."
;;
esacelse————————————————
服务器再次重启后，稍等片刻集群即会正常启动。
正常加载日志：
