linux 11201(11203) ASM RAC 安装

注意：11G的RAC安装，如果升级，则会新建目录在放软件，原来的不删除，所以所需空间比较大。

1。安装系统，把所有的开发包全部安装上

关掉防火墙和SELinux

yum -y install compat-libstdc++*
yum -y install elfutils-libelf-devel*
yum -y install elfutils-libelf-devel-static*
yum -y install gcc*
yum -y install gcc-c++*
yum -y install glibc*
yum -y install glibc-common*
yum -y install glibc-devel*
yum -y install glibc-headers*
yum -y install kernel-headers*
yum -y install ksh*
yum -y install libaio*
yum -y install libaio-devel*
yum -y install libgcc*
yum -y install libgomp*
yum -y install libstdc++*
yum -y install libstdc++-devel*
yum -y install make*
yum -y install sysstat*
yum -y install unixODBC*
yum -y install unixODBC-devel*
yum -y install libXp*

2。修改参数，在文件后面添加如下内容

1）配置核心参数

vi /etc/sysctl.conf

kernel.msgmnb = 65536
fs.file-max = 6815744
kernel.msgmni = 2878
kernel.msgmax = 8192
kernel.msgmnb = 65536
kernel.sem = 250 32000 100 142
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.sysrq = 1
net.core.rmem_default = 1048576
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 3145728
net.ipv4.ip_local_port_range = 9000 65500
vm.min_free_kbytes = 51200

修改完执行此命令： sysctl -p

2）vi /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

之后，执行:$ulimit验证一下.

3) vi /etc/csh.login
if ( $USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
umask 022
endif

4) vi /etc/pam.d/login
session required pam_limits.so

5) vi /etc/security/limits.conf
oracle soft     nofile 655360
oracle hard     nofile 635360
oracle soft    nproc   10240
oracle hard    nproc   16384

3。创建用户和组
/usr/sbin/groupadd -g 551 oinstall
/usr/sbin/groupadd -g 552 dba
/usr/sbin/groupadd -g 554 asmadmin
/usr/sbin/groupadd -g 556 asmdba
/usr/sbin/groupadd -g 557 asmoper

/usr/sbin/useradd -u 551 -g oinstall -G asmadmin,asmdba,asmoper grid
/usr/sbin/useradd -u 552 -g oinstall -G dba,asmdba oracle

设置密码

4。网络
五个共有ip
每个节点两个：物理ip，vip
一个scan ip
两个私有ip

#scanip

192.168.56.245 scanip

#rac3
192.168.56.203 rac3
192.168.56.234 rac3vip
10.10.10.203 rac3priv

#rac4
192.168.56.204 rac4
192.168.56.243 rac4vip
10.10.10.204 rac4priv

如果使用dns，需要三个scan ip
DNS server, then, as the root user, change the hosts search order in
/etc/nsswitch.conf on all nodes as shown here:
Old:
hosts: files nis dns
New:
hosts: dns files nis

5。创建目录

mkdir -p /u01/app/oraInventory
chown -R grid:oinstall /u01/app/oraInventory
chmod -R 775 /u01/app/oraInventory

#创建Oracle Grid Infrastructure Home Directory
mkdir -p /u01/11.2.0/grid

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

chown -R grid:oinstall /u01/app/grid
chmod -R 775 /u01/app/grid

#创建Oracle Base Directory
mkdir -p /u01/app/oracle
mkdir /u01/app/oracle/cfgtoollogs

#创建Oracle RDBMS Home Directory
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle

Oracle用户环境变量

export ORACLE_SID=jun1

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1/

export PATH=$ORACLE_HOME/bin:$GRID_HOME/bin:$PATH:$ORACLE_HOME/OPatch

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/rdbms/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib

grid 用户环境变量

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/11.2.0/grid

export ORACLE_SID=+ASM1

export PATH=$PATH:$ORACLE_HOME/bin

6。划分磁盘和裸设备映射

fdisk -l 查看盘为 /dev/sdb

rac3添加了两个:

fdisk /dev/sdb

另一个节点执行：fdisk /dev/sdb ，最后输入w

修改两个节点的文件

cd /etc/udev/rules.d

vi 60-raw.rules

ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"
KERNEL=="raw[1-2]", OWNER="grid", GROUP="asmadmin", MODE="0660"

最后可以不用，但是必须修改权限，但是生产环境一般都有。

两个节点都执行 start_udev

查看 ls –l /dev/raw

7。配置互信(用grid用户执行，在一边配就可以了。)

Setup SSH user equivalency
===================================================
Use grid user on all nodes: rm -rf $HOME/.ssh
$GI_OUI/sshsetup/sshUserSetup.sh -user grid -hosts "rac3 rac4" -advanced -noPromptPassphrase
$OUI_HOME/sshsetup/sshUserSetup.sh -user oracle -hosts "rac3 rac4" -advanced -noPromptPassphrase

配置后测试互信是否通
8。安装grid

用grid 用户安装
