Linux 6.5（Oracle 11.2.0.4）单实例ASM安装
1、解析主机、配置网络等
/etc/hosts
/etc/sysconfig/network
/etc/init.d/NetworkManager stop
chkconfig NetworkManager off
iptables -F
service iptables save
sed -ri 's/^SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux
2、配置yum
cd /etc/yum.repos.d/
touch yum_oel5.repo
vi yum_oel5.repo
添加以下内容：
[oel6]
name=oel6
baseurl=file:///mnt/Server
gpgcheck=0
enabled=1
yum clean all
yum repolist
yum list
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
Pdksh 一定要先装，不然后面会报错的
3、修改系统参数
调整内核参数，并使其生效
vi /etc/sysctl.conf
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
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 = 1048576
fs.aio-max-nr = 1048576
sysctl -p
修改limits.conf
vi /etc/security/limits.conf
oracle settings
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
修改/etc/pam.d/login
vi /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so
修改/etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
修改/etc/csh.login
if ( $USER == "oracle" ) then
limit maxproc 16384
limit deors 65536
endif
4、
--添加用户和组（非Oracle Linux环境配置）
groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
groupadd -g 504 asmadmin
groupadd -g 505 asmdba
groupadd -g 506 asmoper
useradd -u 500 -g oinstall -G dba,asmdba,asmadmin,oper oracle
useradd -u 507 -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid
注意，oper组不是必须的，dba,asmdba,asmadmin必须有
--修改grid和oracle用户密码
passwd oracle
passwd grid
--配置环境变量
grid:
export ORACLE_SID=+ASM
export ORACLE_BASE=/home/u01/grid
export ORACLE_HOME=$ORACLE_BASE/11.2.0
export PATH=$ORACLE_HOME/bin:$PATH:/usr/local/bin/:
export NLS_LANG=American_america.ZHS16GBK
export TEMP=/tmp
export TMP=/tmp
export TMPDIR=/tmp
umask 022
oracle:
ORACLE_SID=ydasm; export ORACLE_SID
ORACLE_BASE=/home/u01/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
GRID_HOME=/home/u01/grid/11.2.0; export GRID_HOME
NLS_DATE_FORMAT="YYYY:MM:DD HH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=american_america.ZHS16GBK; export NLS_LANG
PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$GRID_HOME/bin export PATH
export NLS_LANG=American_america.ZHS16GBK
export TEMP=/tmp
export TMPDIR=/tmp
umask 022
主要是配置几个环境变量必须
mkdir -p /home/u01/grid/11.2.0
mkdir -p /home/u01/grid
mkdir -p /home/u01/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /home/u01
chmod -R 775 /home/u01
5、上传Oracle安装介质到/u01/tmp目录下
mkdir -p /u01/tmp
p13390677_112040_Linux-x86-64_1of7.zip
p13390677_112040_Linux-x86-64_2of7.zip
p13390677_112040_Linux-x86-64_3of7.zip
6、vi /etc/RedHat-release
Red Hat Enterprise Linux Server release 4.0 (Santiago)
7、安装grid组件
--利用udev绑定磁盘
for Linux 6.x
for i in b c d;
do
echo "KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u /dev/$name",
RESULT=="/sbin/scsi_id -g -u /dev/sd$i", NAME="asm-disk$i", OWNER="grid",
GROUP="asmadmin", MODE="0660""
done
for Linux 5.x
for i in b c d;
do
echo "KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="scsi_id -g -u -s /block/sd$i", NAME="asm-disk$i", OWNER="grid", GROUP="asmadmin", MODE="0660""
done
使用的时候要注意在不同版本上脚本的区别，否则获取不到磁盘的scsi_id
[root@rac1 ]# /sbin/service ntpd stop
关闭 ntpd： [失败][root@rac1 ]# chkconfig ntpd off
[root@rac1 ]# mv /etc/ntp.conf /etc/ntp.conf.original
直接使用裸设备的方法：
1.在RHEL6以前的可以直接通过rawdevices的管理方法，系统安装后默认已存在/etc/init.d/rawdevices和/etc/sysconfig/rawdevices这两个文件。
1.在RHEL6中，系统里面虽然已经不存在/etc/sysconfig/rawdevices和/etc/init.d/rawdevices文件了，但是依然支持rawdevices的方式，可以通过如下方法来管理raw文件。
a.手动创建/etc/sysconfig/rawdevices和/etc/init.d/rawdevices文件，然后依然以rawdevices的方式
b.通过udev来管理raw,同样也可以通过udev固定磁盘对应的设备名
采用新建的方法
vi /etc/init.d/rawdevices
!/bin/bash
rawdevices This shell script assignes rawdevices to block devices
chkconfig: 345 56 44
description: This scripts assignes raw devices to block devices
(such as hard drive partitions). This is for the use
of applications such as Oracle. You can set up the
raw device to block device mapping by editing
the file /etc/sysconfig/rawdevices.
config: /etc/sysconfig/rawdevices
[ -f /bin/raw ] || exit 0
[ -f /etc/sysconfig/rawdevices ] || exit 0
Exit if the file just has the default comments.
LC_ALL=C /bin/egrep -q -v "^ #" /etc/sysconfig/rawdevices 2>/dev/null || exit 0
. /etc/init.d/functions
function assign_raw()
{
LC_ALL=C egrep -v '^ #' /etc/sysconfig/rawdevices |
while read RAW BLOCK; do
if [ -n "$RAW" -a -n "$BLOCK" ]; then
rawdirname=${RAW%/*}
if [ "$rawdirname" = "/dev" -a -d /dev/raw ]; then
echo $" Please correct your /etc/sysconfig/rawdevices:"
echo $" rawdevices are now located in the directory /dev/raw/ "
echo $" If the command 'raw' still refers to /dev/raw as a file."
echo $" you'll have to upgrade your util-linux package"
exit 0
fi
if [ "$rawdirname" = "/dev/raw" -a -f /dev/raw ]; then
echo $" Please correct your /etc/sysconfig/rawdevices:"
echo $" rawdevices are now located in the directory /dev/raw/ "
echo $" If the command 'raw' still refers to /dev/raw as a file."
echo $" you'll have to upgrade your util-linux package"
exit 0
fi
echo " $RAW --> $BLOCK";
raw $RAW $BLOCK
fi
done
}
See how we were called.
case "$1" in
start)
# Assign devices
echo $"Assigning devices: "
assign_raw
添加以下两行(默认不存在)，即默认情况下生成的裸设备为root所有，
所以必须修改属主，否则oracle用户无法使用裸设备
sleep 5
chown -R grid:asmadmin /dev/raw/
echo $"done"
;;
stop)
# No action to be taken here
;;
status)
ID=id -u
if [ $ID -eq 0 ]; then
raw -qa
else
echo $"You need to be root to use this command ! "
fi
;;
restart|reload)
$0 start
;;
*)
echo $"Usage: $0 {start|stop|status|restart}"
exit 1
esac
exit 0
--------------------------------------------------------------------------------
vi /etc/sysconfig/rawdevices //映射将要绑定的裸设备
/dev/raw/raw5 /dev/sdb
/dev/raw/raw6 /dev/sdc
/dev/raw/raw7 /dev/sdd
/dev/raw/raw8 /dev/sde
[root@rac1]# chkconfig rawdevices on
[root@rac1]# service rawdevices start
1.4 绑定裸设备（用于创建ASM磁盘组，更详细的内容请参考：）

[root@ydtest host2]# echo '- - -' > scan
[root@ydtest host2]#
[root@ydtest host2]# cd ../host0

虚拟机加盘后 扫描盘

--重启udev，使配置生效

如果执行脚本的时候停在Adding daemon to inittab,这是 11.2.0.1和11.2.0.2 在RHEL6上的bug,可以以root身份执行以下命令：
[root@rac1]# dd if=/var/tmp/.oracle/npohasdof=/dev/null bs=1024 count=1

$ echo $ORACLE_SID
