报错原因：
因为RHEL 7使用systemd而不是initd运行进程和重启进程，而root.sh通过传统的initd运行ohasd进程。
解决方法：
在RHEL 7中ohasd需要被设置为一个服务，在运行脚本root.sh之前。
步骤如下：
1. 以root用户创建服务文件
#touch /usr/lib/systemd/system/ohas.service
#chmod 777 /usr/lib/systemd/system/ohas.service
2. 将以下内容添加到新创建的ohas.service文件中
[root@rac1
init.d]# cat
/usr/lib/systemd/system/ohas.service
[Unit]
Description=Oracle High
Availability
Services
After=syslog.target
[Service]
ExecStart=/etc/init.d/init.ohasd
run >/dev/null 2>&1
Type=simple
Restart=always
[Install]
WantedBy=multi-user.target
3. 以root用户运行下面的命令
systemctl
daemon-reload
systemctl enable
ohas.service
systemctl start
ohas.service
4.
查看运行状态
[root@rac1
init.d]# systemctl status ohas.service

此时状态为失败，原因是现在还没有/etc/init.d/init.ohasd文件。
下面可以运行脚本root.sh 不会再报ohasd failed to start错误了。
如果还是报ohasd failed to start错误，可能是root.sh脚本创建了init.ohasd之后，ohas.service没有马上启动，解决方法参考以下：
当运行root.sh时，一直刷新/etc/init.d ，直到出现 init.ohasd 文件，马上手动启动ohas.service服务 命令：systemctl start ohas.service
[root@rac1
init.d]# systemctl status ohas.service
ohas.service - Oracle High
