3.

報錯原因：

因為 RHEL 7 使用 systemd 而不是 initd 運行進程和重啟進程，而 root.sh 通過傳統的 initd 運行 ohasd 進程。

解決方法：

在 RHEL
7 中 ohasd 需要被設置為一個服務，在運行腳本 root.sh 之前。

步驟如下：

以 root 用戶創建服務文件

#touch /usr/lib/systemd/system/ohas.service

#chmod 777 /usr/lib/systemd/system/ohas.service

2. 將以下內容添加到新創建的 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 用戶運行下面的命令

systemctl
daemon-reload
systemctl enable
ohas.service
systemctl start
ohas.service
4.
查看運行狀態

[root@rac1
init.d]# systemctl status ohas.service
ohas.service – Oracle High
Availability Services
Loaded: loaded
(/usr/lib/systemd/system/ohas.service; enabled)
Active: failed (Result: start-limit) since Fri 2015-09-11

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

此時狀態為失敗，原因是現在還沒有 /etc/init.d/init.ohasd 文件。

下面可以運行腳本 root.sh
不會再報 ohasd failed to start 錯誤了。

如果還是報 ohasd failed to
start 錯誤，可能是 root.sh 腳本創建了 init.ohasd 之后，ohas.service 沒有馬上啟動，解決方法參考以下：

當運行 root.sh 時，一直刷新 /etc/init.d
，直到出現 init.ohasd 文件，馬上手動啟動 ohas.service 服務命令：systemctl start
ohas.service

[root@rac1
init.d]# systemctl status ohas.service
ohas.service – Oracle High
Availability Services
Loaded: loaded
(/usr/lib/systemd/system/ohas.service; enabled)
