安装系统包

#!/bin/bash

#配置yum本地源

cat >> /etc/yum.repos.d/source.repo << EOF

[Server]

baseurl=file:///mnt/Server

enabled=1

gpgcheck=0

EOF

echo "starting installing required packages"

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

创建用户和组

#!/bin/bash

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

echo -n oracle|passwd --stdin grid
echo -n oracle|passwd --stdin oracle
mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
chown grid:oinstall /u01/app/11.2.0/grid
chown grid:oinstall /u01/app/grid
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/
chown -R grid:oinstall /u01

修改系统内核参数

#!/bin/bash

sed -i 's/kernel.shmmax/#kernel.shmmax/g' /etc/sysctl.conf
sed -i 's/kernel.shmall/#kernel.shmall/g' /etc/sysctl.conf

cat >> /etc/sysctl.conf << EOF

fs.file-max = 6815744

kernel.shmmax = 1073741824
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
EOF

cat >> /etc/security/limits.conf << EX

oracle soft nofile 1024

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

修改profile

#!/bin/bash

cat >> /etc/profile << EOF
if [ \$USER = "oracle" ] || [ \$USER = "grid" ];then
if [ \$SHELL = "/bin/ksh" ];then
ulimit -p 16384
ulimit -n 65536

ulimit -u 16384 -n 65536
