Oracle Grid Infrastructure安装配置

1.检查主机及IP地址

hostname
vi /etc/sysconfig/network
vi /etc/hosts

2.安装依赖包

yum install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh compat-libcap1

附yum本地源配置

mkdir -p /mnt/cdrom
mount -o loop -t iso9660 /home/rhel-server-6.2-x86_64-dvd.iso /mnt/cdrom
vi /etc/yum.repos.d/rhel-source.repo
[ISO]
name=iso
baseurl=file:///media/cdrom/Server/
enabled=1
gpgcheck=0

如果安装失败，可以删除其它repo文件

没有图形界面需安装xterm

yum groupinstall "X Window System"
yum install xterm

3.关闭防火墙

service iptables stop
chkconfig iptables off

4.创建oracle用户级用户组成员

groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
groupadd asmdba
groupadd asmoper
useradd -g oinstall -G dba,asmdba,oper oracle
useradd -g oinstall -G dba,asmadmin,asmdba,asmoper grid
passwd oracle
passwd grid

5.创建目录并授权

mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app

6.用户环境变量

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:.
export NLS_LANG=american_america.ZHS16GBK
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin:.

export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:.
export NLS_LANG=American_america.ZHS16GBK
export PATH=$PATH:$ORACLE_HOME/bin:.
export ORACLE_SID=+ASM

7.系统参数修改

vi /etc/sysctl.conf

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4398046511104 //一般设置为系统内存75%单位是字节
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

vi /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 1024

vi /etc/pam.d/login

#oracle
session required /lib64/security/pam_limits.so
session required pam_limits.so

8.添加裸设备

fdisk -l #查看磁盘分区
/usr/lib/udev/scsi_id -g -u /dev/sdb
/usr/lib/udev/scsi_id -g -u /dev/sdc
/usr/lib/udev/scsi_id -g -u /dev/sdd #如果未vm虚拟机磁盘，需修改vmx文件，加入disk.enableUUID = "TRUE"，否则获取uuid为空白

udev绑定

为使设备可以被ASM可用，Linux提供三种技术支持

• ASMLib核心库 针对个别内核低于3的版本使用，使用不多

• ASM过滤器驱动程序 该功能充12.1.0.2版本开始提供，可替代ASMLib。禁止非oracle进程写入asm磁盘

• udev功能 自定义强

引用自飞总博客https://www.xifenfei.com/2016/08/linux-7-udev.html
vim /etc/udev/rules.d/99-my-asmdevices.rules #自定义改文件，加入如下内容

KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",
 RESULT=="36000c292495e9d9de6f21640cc7b53b9", RUN+="/bin/sh -c 'mknod /dev/xifenfei-sdc b $major $minor;
chown oracle:dba /dev/xifenfei-sdc; chmod 0660 /dev/xifenfei-sdc'"
 
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id -g -u -d /dev/$parent",
RESULT=="36000c29e91831cedbe69afe6cc08daf7", SYMLINK+="xifenfei-sdb1", OWNER="oracle", GROUP="dba", MODE="0660"

手残选手请选用下面bash脚本

#!/bin/bash
for i in b c d e f;
do
 echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"">>/etc/udev/rules.d/80-asm.rules
done

启动udev

start_udev
ll /dev/asm-disk*  --查看对应关系

9.安装

export DISPLAY=192.168.2.1:0(远程机器)
xhost +
export LANG=c
./runInstaller
