 .安装GI执行root.sh脚本时,ohasd 进程无法正常启动

 ohasd failed to start
 Failed to start the Clusterware. Last  lines of the alert log follow:
 -- ::30.897:
 [client()]CRS-:The OLR was formatted using version .

 alert:

 Oracle High Availability Service has timed out waiting for init.ohasd to be started.

 因为Oracle Linux (和Redhat )使用systemd而不是initd来启动/重新启动进程,并将它们作为服务运行,所以当前的11.2.0.4和12.1.0.1的软件安装不会成功,因为ohasd进程没有正常启动。

 解决方法一:

 在root.sh执行之前先打上补丁:。

 解决方法二:手动在systemd中添加ohasd服务

 ().创建一个空服务文件:/usr/lib/systemd/system/ohasd.service

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

 ().编辑文件ohasd.service添加如下内容

 vi   /usr/lib/systemd/system/ohasd.service

 [Unit]
 Description=Oracle High Availability Services
 After=syslog.target

 [Service]
 ExecStart=/etc/init.d/init.ohasd run >/dev/>& Type=simple
 Restart=always

 [Install]
 WantedBy=multi-user.target

 ().添加和启动服务

 systemctl daemon-reload
 systemctl enable ohasd.service
 systemctl start ohasd.service

 查看运行状态:

 [root@rac1 system]# systemctl status ohasd.service
 ● ohasd.service - Oracle High Availability Services
 Loaded: loaded (/usr/lib/systemd/system/ohasd.service; enabled; vendor preset: disabled)
 Active: active (running) since Thu -- :: CST; 1h 16min ago

 └─ /bin/>& Type=simple

 Apr  :: bms-75c8 systemd[]: Started Oracle High Availability Services.
 Apr  :: bms-75c8 systemd[]: Starting Oracle High Availability Services...

 ().重新执行root.sh脚本

 注意: 为了避免其余节点遇到这种报错,可以在root.sh执行过程中,待/etc/init.d/目录下生成了init.ohasd 文件后执行systemctl start ohasd.service 启动ohasd服务即可。若没有/etc/init.d/init.ohasd文件 systemctl start ohasd.service 则会启动失败。

 .安装database软件,在执行root.sh脚本的时候会报错:

 Error in invoking target 'agent nmhs' of makefile '/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk'
 解决方法一:
 选择 继续,然后打上补丁:
 解决方法二:
 编辑文件 $ORACLE_HOME/sysman/lib/ins_emagent.mk
 /db_1/sysman/lib/ins_emagent.mk
 找到 $(MK_EMAGENT_NMECTL) 这一行,在后面添加 -lnnz11 如下:
 $(MK_EMAGENT_NMECTL) -lnnz11
 然后点击retry 即可

 报错信息
 [root@rac1 ~]# /u01/app//grid/crs/install/rootcrs.pl -deconfig -verbose -force

 解决方法:

 根据提示信息Can't locate Env.pm 可以知道找不到这玩意了。所以cp一份过去

 [root@rac2 ~]#/grid//Env.pm /usr/lib64/perl5/vendor_perl/

 就OK了!记录一下
