1. 数据库安装成功之后；发现ohasd进程存在异常；
[root@oracle234 ~]# su - grid
[grid@oracle234 ~]$ ps -ef| grep ohasd
grid 6931 1 0 Dec23 ? 00:24:27 /u01/app/grid/11.2.0/grid/bin/ohasd.bin reboot
grid 17361 17324 0 13:55 pts/0 00:00:00 grep ohasd
[grid@oracle234 ~]$ exit
logout
[root@oracle234 ~]# /etc/init.d/init.ohasd run
mkfifo: 无法创建先进先出文件"/var/tmp/.oracle/npohasd": 文件已存在
网上有解决该问题的示例 ；参考博客 --https://oracleblog.org/working-case/ohasd-can-not-auto-start-with-server-reboot/
看来使用linux6.×安装GI；其中GI的版本还是选择11.2.0.3版本；或者升级到该版本。

出现“ CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.”
CRS-4000: Command Start failed, or completed with errors.”
解决方案
在执行crsctl start has 同时另起一个窗口用root用户执行/etc/init.d/init.ohasd run &
