Centos 5.5安装oracle11gR2前期准备工作
1.1. 配置主机IP 地址
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.40.255
HWADDR=50:E5:49:87:71:11
IPADDR=192.168.1.120
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
1.2. 修改主机名并增加主机IP
# vim /etc/hosts
192.168.1.120 oracle.localdomain
1.3. 检查系统支持库文件
# rpm -q gcc make binutils setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel unixODBC unixODBC-devel libaio-devel sysstat
gcc-4.1.2-48.el5
make-3.81-3.el5
binutils-2.17.50.0.6-14.el5
setarch-2.0-1.1
package compat-db is not installed
package compat-gcc is not installed
package compat-gcc-c++ is not installed
package compat-libstdc++ is not installed
package compat-libstdc++-devel is not installed
package unixODBC is not installed
package unixODBC-devel is not installed
package libaio-devel is not installed
package sysstat is not installed
1.4. 检查依赖包
可以使用通配符*，如：rpm -qa|grep binutils-*
rpm -qa|grep binutils-2.17.50.0.6-2.el5 centos 5.5系统安装时会装好
rpm -qa|grep compat-libstdc++-33-3.2.3-61 centos 5.5系统安装时会装好
rpm -qa|grep elfutils-libelf-0.125-3.el5 centos 5.5系统安装时会装好
rpm -qa|grep elfutils-libelf-devel-0.125-3.el5centos 5.5系统安装时会装好
rpm -qa|grep glibc-2.5-12 centos 5.5系统安装时会装好
rpm -qa|grep glibc-devel-2.5-12 centos 5.5系统安装时会装好
rpm -qa|grep glibc-common-2.5-12 centos 5.5系统安装时会装好
rpm -qa|grep gcc-4.1.1-52.el5 centos 5.5系统安装时会装好
rpm -qa|grep gcc-c++-4.1.1-52.el5 centos 5.5系统安装时会装好
rpm -qa|grep libgcc-4.1.1-52.el5 centos 5.5系统安装时会装好
rpm -qa|grep libaio-0.3.106-3.2 centos 5.5系统安装时会装好
rpm -qa|grep libaio-devel-0.3.106-3.2
rpm -qa|grep libstdc++-4.1.1-52.el5 centos 5.5系统安装时会装好
rpm -qa|grep libstdc++-devel-4.1.1-52.el5 centos 5.5系统安装时会装好
rpm -qa|grep make-3.81-1.1 centos 5.5系统安装时会装好
rpm -qa|grep pdksh-5.2.14-36.el5.i386.rpm
rpm -qa|grep sysstat-7.0.0-3.el5
rpm -qa|grep unixODBC-2.2.11-7.1
rpm -qa|grep unixODBC-devel-2.2.11-7.1
1.5. 安装缺少库文件
使用YUM进行安装
#Yum install gcc make binutils setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel unixODBC unixODBC-devel libaio-devel sysstat
1.6. 创建用户与组
#groupadd dba
#groupadd oinstall
#useradd oracle -g oinstall -G dba
#passwd oracle
2. 修改系统内核与参数
2.1. 参数说明
/etc/sysctl.conf (修改内核参数)
/etc/security/limits.conf (shell对oracle用户的限制)
/etc/profile (系统相关的环境变量)
2.2. 修改内核
vim /etc/sysctl.conf
修改与添加如下内容：
# Kernel Oracle 11g R2
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 = 1048586
保存退出，执行以下命令，使设置的内核参数生效
sysctl –p
2.3. shell对oracle用户的限制
vim /etc/security/limits.conf
在文件的末尾加入以下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
2.4. 修改/etc/pam.d/login
| Session required pam_limits.so |
2.5. 修改/etc/profile
vim /etc/profile
在文件的末尾加入以下内容：
修改完成后使用source /etc/profiel生效
| if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi |
