Oracle故障处理之linux 7安装11gR2时运行root.sh报错（ohasd failed to start）

1. 创建服务ohas.service的服务文件并赋予权限

[root@rac1 grid]# touch /usr/lib/systemd/system/ohas.service

[root@rac1 grid]# chmod 777 /usr/lib/systemd/system/ohas.service

2. 为ohas.service服务文件添加启动ohasd的相关信息

[root@rac1 grid]# 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

3. 加载，启动服务

重新加载守护进程

[root@rac1 grid]# systemctl daemon-reload

设置守护进程自动启动

[root@rac1 grid]# systemctl enable ohas.service

手工启动ohas服务

[root@rac1 grid]# systemctl start ohas.service

查看服务的状态

[root@rac1 grid]# systemctl status ohas.service

4. 重新运行root.sh脚本

[root@rac1 grid]# ./root.sh
