# rpm -qa |grep make
make-3.81-20.el6.x86_64

# yum --disablerepo=* --enablerepo=c6-media install libXp.i686

# yum --disablerepo=* --enablerepo=c6-media install libXt.i686

1.1.6、配置内核参数

# vi /etc/sysctl.conf ##原始的shmmax/shmall 比较大
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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

# /sbin/sysctl –p
error: "–p" is an unknown key
# sysctl -p

1.1.7、配置会话限制

# vi /etc/pam.d/login ##末尾添加
session required pam_limits.so

1.1.8、软件安装用户的资源限制

# vi /etc/security/limits.conf
oracle hard nproc 204800
oracle soft nofile 204800
oracle hard nofile 204800
oracle soft stack 204800
grid soft nproc 204800
grid hard nproc 204800
grid soft nofile 204800
grid hard nofile 204800
grid soft stack 204800

1.1.9、创建组，创建用户，修改环境变量

# groupadd -g 1000 oinstall
# groupadd -g 1200 asmadmin
# groupadd -g 1201 asmdba
# groupadd -g 1202 asmoper

# useradd -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash grid
# passwd

# vi /home/grid/.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

export PATH=$PATH:$HOME/bin

export PS1="`/bin/hostname -s`->"
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM1
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
# source /home/grid/.bash_profile

# groupadd -g 1300 dba
# groupadd -g 1301 oper
# useradd -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash oracle
# passwd

# vi /home/oracle/.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

export PATH=$PATH:$HOME/bin

export PS1="`/bin/hostname -s`->"
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=node1.localdomain
export ORACLE_SID=devdb1
export ORACLE_UNQNAME=devdb
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

# source /home/oracle/.bash_profile

1.1.10、创建目录,修改权限

# mkdir -p /u01/app/grid ##-p级联
# mkdir -p /u01/app/11.2.0/grid
# chown -R grid:oinstall /u01/app/grid
# chown -R grid:oinstall /u01/app/11.2.0/grid

# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle

最后执行如下命令:
# chmod -R 775 /u01

1.1.11、停止ntp服务,11gR2新增的检查项

# service ntpd status
ntpd is stopped
# chkconfig ntpd off
#
# mv /etc/ntp.conf /etc/ntp.conf.bak

1.2、配置node2

在node2上，重复node1的1.2-1.11，同时配置环境变量时+ASM2/devdb2

1.3、配置grid/oracle用户ssh对等性

##node1
node1->env |grep ORA
ORACLE_UNQNAME=devdb
ORACLE_SID=devdb1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=node1.localdomain
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1

##node2
node2->env |grep ORA
ORACLE_UNQNAME=devdb
ORACLE_SID=devdb2
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=node1.localdomain
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
