标题: linux 7安装rac 11gR2时运行root.sh报错找不到ohas服务

OS版本：Oracle Linux 7.3

DB版本：11.2.0.4 64bit

数据库运行环境：RAC

运行root.sh脚本的时候报错：

[root@rac01 ~]# /u01/app/11.2.0/grid/root.sh

Adding Clusterware entries to inittab

ohasd failed to start

Failed to start the Clusterware. Last 20 lines of the alert log follow:

2018-09-04 16:33:49.623:

[client(68126)]CRS-2101:The OLR was formatted using version 3.

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：

步骤如下
1. 创建服务ohas.service的服务文件并赋予权限

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

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

2. 往ohas.service服务文件添加启动ohasd的相关信息

vi /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

note：把红色部分的内容添加到文件里面

3. 加载，启动服务

重新加载守护进程

systemctl daemon-reload

设置守护进程自动启动

systemctl enable ohas.service

手工启动ohas服务

systemctl start ohas.service

4. 重新运行root.sh脚本

[root@rac02 ~]# /u01/app/11.2.0/grid/root.sh
