/dev/asmdisk01 /dev/asmdisk02 /dev/asmdisk03
解压grid安装包
Root用户运行运行图形化
[root@rac1 u01]# xhost +
切换用户
[root@rac1 u01]# su – grid
设置display
(xmanager远程连接运行图像化)
[grid@rac1 ~]$ export DISPLAY=远程机器的IP地址:0.0
安装grid
[grid@rac1 ~]$ cd /u01/grid/
[grid@rac1 grid]$ ./runInstaller
挂载光盘
[root@rac1 dev]# mount /dev/cdrom /mnt/
安装所需依赖包(rac1和rac2)
[root@rac1 /]# cd /mnt/Packages
[root@rac1 Packages]# rpm -ivh elfutils-libelf-devel-0.163-3.el7.x86_64.rpm
[root@rac1 Packages]# rpm -ivh libaio-devel-0.3.109-13.el7.x86_64.rpm
缺少pdksh-5.2.14这个包,网上下载,安装依赖包
[root@rac1 u01]# rpm -ivh pdksh-5.2.14-37.el5_8.1.x86_64.rpm
运行脚本(rac1和rac2)
[root@rac1 system]# cd /u01/app/oraInventory/
[root@rac1 system]# ./orainstRoot.sh
[root@rac1 system]# cd /u01/app/11.2.0/grid/
[root@rac1 system]# ./root.sh
运行root脚本报错
ohasd failed to start
Failed to start the Clusterware. Last 20 lines of the alert log follow:
2015-05-23 23:37:45.460:
[client(13782)]CRS-2101:The OLR was formatted using version 3.
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:
取消root.sh重新运行
/u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force –verbose
1. 以root用户创建服务文件
#touch /usr/lib/systemd/system/ohas.service
#chmod 777 /usr/lib/systemd/system/ohas.service
2. 将以下内容添加到新创建的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
3. 以root用户运行下面的命令
systemctl daemon-reload
systemctl enable ohas.service
systemctl start ohas.service
4. 查看运行状态
[root@rac1 init.d]# systemctl status ohas.service
ohas.service - Oracle High Availability Services

Sep 11 16:07:32 rac1 systemd[1]: Failed to start Oracle High Availability Services.
Sep 11 16:07:32 rac1 systemd[1]: Unit ohas.service entered failed state.
此时状态为失败,原因是现在还没有/etc/init.d/init.ohasd文件。
下面可以运行脚本root.sh 不会再报ohasd failed to start错误了。
如果还是报ohasd failed to start错误,可能是root.sh脚本创建了init.ohasd之后,ohas.service没有马上启动,解决方法参考以下:
当运行root.sh时,一直刷新/etc/init.d ,直到出现 init.ohasd 文件,马上手动启动ohas.service服务 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)

Grid用户:检查是否安装正确完成(rac1和rac2)
[grid@rac1 grid]$ crs_stat –t
配置asm磁盘
使用grid用户执行asmca
[grid@rac1 grid]$ asmca
Root用户解压oracle,oracle用户安装oracle
[oracle@rac1 database]$ ./runInstaller
[oracle@rac1 database]$ export DISPLAY=远程机器的IP地址:0.0
.
Oracle用户:解决方法(rac1)
[oracle@rac1 lib]$ cd /$ORACLE_HOME/sysman/lib
[oracle@rac1 lib]$ cp ins_emagent.mk ins_emagent.mk.bak
[oracle@rac1 lib]$ vi ins_emagent.mk
输入/NMECTL 快速查找,在参数后面加上-lnnz11 第一个是字母l 后两个是数字1
然后回到界面点击retry
运行脚本(rac1和rac2)
[root@rac1 ~]# cd /u01/app/oracle/product/11.2.0/dbhome_1/
[root@rac1 ~]# ./root/sh
Oracle用户DBCA创建数据库(rac1)
注意oracle_sid与之前设置的环境变量里的相符合
至此,安装完成,后续测试该环境是否能够正常运行。
