Oracle安装基本步骤

安装数据库

1.建立用户组及用户

groupadd oinstall

groupadd dba

groupadd oper

useradd -g oinstall -G dba oracle

passwd oracle





2.创建安装目录及权限

mkdir -p /opt/ora10g

chown -R oracle.oinstall /opt/ora10g



3.设置oracle用户的shell limit

vi /etc/security/limits.conf

grid  soft    nproc   2047

grid  hard    nproc   16384

grid  soft    nofile  1024

grid  hard    nofile  65536

grid  soft    stack   10240



oracle  soft    nproc   2047

oracle  hard    nproc   16384

oracle  soft    nofile  1024

oracle  hard    nofile  65536

oracle  soft    stack   10240





4.shell limit生效

vi/etc/pam.d/login

session required pam_limits.so







5.环境变量  .bash_profile

export PATH

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_BASE=/opt/ora10g

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db

export ORACLE_SID=ocp

export ORACLE_TERM=xterm

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$CRS_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

umask 022



6.系统参数

vi /etc/sysctl.conf

kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144

net.core.rmem_max=262144

net.core.wmem_default=262144

net.core.wmem_max=262144





7.runInstall





8.执行脚本

#/oracle/oraInventory/orainstRoot.sh

#/oracle/product/10.2.0/db_1/root.sh
