CentOS下Oracle安装

检查系统环境 grep MemTotal /proc/meminfo #检查物理内存 grep SwapTotal /proc/meninfo #检查交换空间 df -k #检查磁盘 安装Oracle需要的环境 yum install -y binutils compat-db compat-libstdc++ control-center gcc gcc-c++ glibc glibc-common libstdc+

检查系统环境

grep MemTotal /proc/meminfo #检查物理内存

grep SwapTotal /proc/meninfo #检查交换空间

df -k #检查磁盘

安装Oracle需要的环境
yum install -y binutils compat-db compat-libstdc++ control-center gcc gcc-c++ glibc glibc-common libstdc++ libXp make ksh sysstat setarch

其中libXp是Oracle OUI需要的环境

检查安装环境

rpm -q --qf &＃39;%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n&＃39; binutils compat-db compat-libstdc++-296 control-center gcc gcc-c++ glibc glibc-common libstdc++ libstdc++-devel libXp make ksh sysstat setarch

有not installed #提示的用yum或光盘重新安装

检查配置内核参数

vi /etc/sysctl.conf

加入

kernel.shmall = 2097152

kernel.shmmax = 536570912 #物理内存

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-mx = 65535

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 1048576

net.core.rmem_max = 1048576

net.core.wmem_default = 262144

net.core.wmem_max = 262144

sysctl -p #检查参数

设置Shell调用限制

vi /etc/security/limits.conf

添加

* soft nproc 2047

* hard nproc 16384

* soft nofile 1024

* hard nofile 65536

vi /etc/pam.d/login

添加

session required /lib/security/pam_limits.so

session required pam_limits.so

创建用户目录

groupadd oinstall

groupadd bda

uuseradd -g oinstall -g dba -m Oracle

passwd Oracle

mkdir /opt/ora10g

mkdir /opt/ora10g/product #Oracle安装目录

mkdir /opt/ora10g/oradata #数据文件目录

mkdir /opt/ora10g/software #安装文件目录

chown -R Oracle:oinstall /opt/ora10g #更改目录属性

配置Oracle用户环境变量

su - Oracle

添加

vi .bash_profile

添加

复制Oracle安装包到/opt/ora10g/software

chown -R Oracle:oinstall /opt/ora10g/software #更改目录属性

cd /opt/ora10g/software/database

./runInstaller -ignoreSysPrereqs

#由于Oracle默认不支持CentOS，安装时加参数-ignoreSysPrereqs 忽略系统检查

提示:

1.在执行runInstaller的时候会有 Permission denied

cd 到该目录 ll -a 检查文件权限，没执行权限用下面的命令给予执行权限

chmod 755 userfile

2.安装时有如下错误提示

Typical path for xclock: /usr/X11R6/bin/xclock

su root #切换到root用户

host +

su Oracle #切换到oracle用户

export DISPLAY=192.168.1.128:0.0

./runInstaller -ignoreSysPrereqs #此时即可通过
