IP规划:

#Public IP

192.168.1.22  rac1

192.168.1.33  rac2

 

#Private IP

1.1.1.111 rac1-priv

1.1.1.222 rac2-priv

 

#Virtual IP

192.168.1.23 rac1-vip

192.168.1.34 rac2-vip

 

#Scan IP

192.168.1.77 rac-scan

 

更改IP地址(rac1和rac2)

[root@rac1 network-scripts]# vi ifcfg-eno16777736

更改:

 

TYPE=Ethernet

BOOTPROTO=static                                                                                                                                                  

DEFROUTE=yes

PEERDNS=yes

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

DNS1=8.8.8.8

~                

由于实验环境缺少网卡2的配置文件,所以自己copy一份手动更改

[root@rac1 network-scripts]# cp ifcfg-eno16777736 ifcfg-eno33554984

[root@rac1 network-scripts]# vi ifcfg-eno33554984

添加:

TYPE=Ethernet

BOOTPROTO=static

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=no

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

GATEWAY=1.1.1.1

DNS1=8.8.8.8

~                                                                                           

根据自己的IP规划,rac2相同操作

 

测试两边能否互相ping通

 

修改主机名

(测试环境安装系统时,已修改好)~

 

查看防火墙状态(rac1和rac2)

 [root@rac1 ~]# systemctl status firewalld     

关闭防火墙(当前状态)

[root@rac1 ~]# systemctl stop firewalld

关闭防火墙(永久)

[root@rac1 ~]# systemctl disable firewalld

 

 

 

修改host文件(rac1和rac2)

[root@rac2 network-scripts]# vi /etc/hosts

开启虚拟机

 

查看磁盘是否挂载(rac1和rac2)

[root@rac1 ~]# fdisk –l

Oracle linux7.2安装11g RAC

查询磁盘UUID(rac1和rac2)

如果uuid查询不到,检查添加的虚拟机文件是否正确

虚拟机的vmx文件增加了disk.enableUUID = "TRUE" 

 

[root@rac1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdb

36000c2917d180b5daef20885fa95bfbe

36000c29c91113958099603eb65a72ce3

 

配置udev rules文件

/etc/udev/rule.d/99-oracle-asmdevices.rules

[root@rac1 rules.d]# vi 99-oracle-asmdevices.rules

 

添加:

KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block",  PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",  RESULT=="36000c29e1359ab575540edf6a00fd489", RUN+="/bin/sh -c 'mknod /dev/asmdisk01 b  $major $minor; chown grid:oinstall /dev/asmdisk01; chmod 0660 /dev/asmdisk01'"

KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block",  PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",  RESULT=="36000c29c692398db6baa48338cc7b9b8", RUN+="/bin/sh -c 'mknod /dev/asmdisk03 b  $major $minor; chown grid:oinstall /dev/asmdisk03; chmod 0660 /dev/asmdisk03'"

 

 

运行:(rac1和rac2)

检查新的设备名称:

[root@rac1 rules.d]# /sbin/udevadm trigger --type=devices --action=change

 

重新加载UDEV(rac1和rac2)

[root@rac1 rules.d]# /sbin/udevadm control –reload

 

为了诊断udev(rac1和rac2)

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdb

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdc

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdd

 

查看是否绑定成功

[root@rac1 rules.d]# ls /dev/asm*

/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

[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

   Loaded: loaded (/usr/lib/systemd/system/ohas.service; enabled)

   Active: failed (Result: start-limit) since Fri 2015-09-11 16:07:32 CST; 1s ago

  Process: 5734 ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple (code=exited, status=203/EXEC)

 Main PID: 5734 (code=exited, status=203/EXEC)

Sep 11 16:07:32 rac1 systemd[1]: Started Oracle High Availability Services.

Sep 11 16:07:32 rac1 systemd[1]: Unit ohas.service entered failed state.

Sep 11 16:07:32 rac1 systemd[1]: Starting Oracle High Availability Services...

Sep 11 16:07:32 rac1 systemd[1]: ohas.service start request repeated too quickly, refusing to start.

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)

   Active: active (running) since Fri 2015-09-11 16:09:05 CST; 3s ago
