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

如果遇到如下所示，纯属正常，可直接点skip跳过之。

9。安装oracle软件(oracle用户)

10。建库
