(二)  解决方法 

        （1）先回退root.sh脚本操作

--安装必要的依赖包
yum install perl-Env

-- ORACLE_HOME=/u01/app/grid/11.2.0/
-- 注意用root用户操作，回退root.sh 脚本操作
/u01/app/grid/11.2.0/crs/install/roothas.pl -deconfig -force -verbose

        （2）创建服务ohas.service

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
cat >> /usr/lib/systemd/system/ohas.service </dev/null 2>&1 Type=simple
Restart=always

[Install]
WantedBy=multi-user.target

EOF

        （3）启动服务并查看状态

加载、启动服务
systemctl daemon-reload
systemctl enable ohas.service
systemctl start ohas.service

查看ohas服务状态
systemctl status ohas.service

                注意：状态是这样的，一看就有问题，不用担心

                再次执行2个root脚本，root用户，发现还是启动失败，再次回退

                回退后执行systemctl 命令启动ohas服务，这样这个服务就是running了

/u01/app/oraInventory/orainstRoot.sh

/u01/app/grid/11.2.0/root.sh

/u01/app/grid/11.2.0/crs/install/roothas.pl -deconfig -force -verbose

回退后再次查看状态并启动，在查看状态

systemctl start ohas.service
systemctl status ohas.service

        （4）重新执行root

                查看odhs状态是running的时候在执行root就会成功

/u01/app/oraInventory/orainstRoot.sh

/u01/app/grid/11.2.0/root.sh  

                

                继续完成gi的安装

                欧耶！解决
