注意:所有需要在两台主机上都设置的操作都有注明,贴出过程仅以rac1为模版

 

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

PEERROUTES=yes

IPV4_FaiLURE_FATAL=no

IPV6INIT=no

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME=eno16777736

UUID=eeaef3ba-b1fe-498f-95e8-3a982ec8931e

DEVICE=eno16777736

ONBOOT=yes

IPADDR=192.168.1.22

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

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME=eno33554984

UUID=7b040b98-b78e-44fa-91e1-5e115f0bdd9f

DEVICE=eno33554984

ONBOOT=yes

IPADDR=1.1.1.111

NETMASK=255.255.255.0

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

添加:

#Public IP

172.16.171.22  rac1

172.16.171.33  rac2

 

#Private IP

1.1.1.111 rac1-priv

1.1.1.222 rac2-priv

 

#Virtual IP

172.16.171.23 rac1-vip

172.16.171.34 rac2-vip

 

#Scan IP

172.16.171.77 rac-scan

 

重启网络服务(rac1和rac2)

[root@rac1 ~]# service network restart

 

配置内核参数(rac1和rac2):[root@rac1 ~]# vi /etc/sysctl.conf

添加:

# for oracle 11g

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2147483648

kernel.shmmax = 68719476736

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586

 

使参数生效(rac1和rac2):[root@rac1 ~]# /sbin/sysctl –p

 

更改limits文件(rac1和rac2):[root@rac1 ~]# vi /etc/security/limits.conf

添加:

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then

if [ $shell = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

umask 022

fi

 

关闭selinux(rac1和rac2):[root@rac1 ~]#  vi /etc/selinux/config

修改:SELINUX=disabled

添加:

[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]: Starting Oracle High Availability Services...

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

Sep 11 16:07:32 rac1 systemd[1]: ohas.service: main process exited, code=exited, status=203/EXEC

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

Sep 11 16:07:32 rac1 systemd[1]: ohas.service holdoff time over, scheduling restart.

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

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

 Main PID: 6000 (init.ohasd)

   CGroup: /system.slice/ohas.service

           6000 /bin/sh /etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple
