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：

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

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
ohas.service – Oracle High

   Loaded: loaded
(/usr/lib/systemd/system/ohas.service; enabled)
   Active: failed (Result: start-limit) since Fri 2015-09-11

Sep 11 16:07:32 rac1 systemd[1]: Unit ohas.service entered failed

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
