rhel5安装 oracle11

readhat 安装11gr2文档

需要注意的地方：必须关掉的 1，防火墙；2，SElinux 。

root 用户运行  setup  命令可关防火墙与SElinux

修改网络配置文件，一定要重启此文件才能生效。

1. 检查内存，至少1G
grep MemTotal /proc/meminfo

grep "model name" /proc/cpuinfo
grep SwapTotal /proc/meminfo

[root@rhel5 ~]# free
             total       used       free     shared    buffers     cached
    Mem:       1035140     512924     522216          0      51236     335880
    -/+ buffers/cache:     125808     909332
    Swap:      1052248          0    1052248

3. 共享内存段至少要大于MEMORY_MAX_TARGET and MEMORY_TARGET 
    [root@rhel5 ~]# df -k /dev/shm/
    Filesystem           1K-blocks      Used Available Use% Mounted on
    tmpfs                   517568         0    517568   0% /dev/shm

4. 至少1G的 /tmp
df -h /tmp

    Standard Edition        3.88

Installation Type        Requirement for Data Files (GB) 
    Enterprise Edition        1.7

6. 操作系统版本
    Operating System Requirements
    The following are the operating system requirements for Oracle Database 11g Release 2 (11.2) for Linux x86:

    [root@rhel5 ~]# uname -s
    Linux

7. 安装必备的软件包

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*

8. 创建组和用户
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba oracle

如果oracle用户已经存在
/usr/sbin/usermod -g oinstall -G dba oracle

echo oracle | passwd --stdin oracle

9. 修改内核参数

shmmax - 共享内存段的最大字节数，建议设大点，甚至可以大过物理内存的字节数
shmmin - 共享内存段的最小尺寸.
shmmni - 共享内存段的最大数目.
shmseg - 每个进程可分配的最大共享内存段数目.
shmall - 最大的并发共享内存段数目，比SGA还要大.
semmns - 信号灯的最大数量，跟ORACLE的PROCESS数有关.
semmsl - 每个信号灯集合中最多的信号灯数目.

vi /etc/sysctl.conf

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

修改完执行此命令 ： sysctl -p

10. vi /etc/security/limits.conf
oracle           soft    nproc   2047
oracle           hard    nproc   16384
oracle           soft    nofile  1024
oracle           hard    nofile  65536

11. vi /etc/pam.d/login
session    required     pam_limits.so

12. 修改profile
if [ $USER = "oracle" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536
        fi
fi

13. 创建目录结构

mkdir -p /u01/app/oracle/product/11.2/db_1

mkdir /u01/software
chown -R oracle:oinstall /u01
chmod -R 775 /u01

14.

vi /home/oracle/.bash_profile

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2/db_1
export ORACLE_SID=junn
export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin
export PATH

15.

./runInstaller  -ignoreSysPrereqs
