一、硬件检测
1、内存检测 Oracle11g要求最低1GB内存
命令: grep MemTotal /proc/meninfo
2、交换空间检测 通常交换空间是内存1.5倍
命令: grep SwapTotal /proc/meninfo
3、临时目录/temp检查
命令:df -k /temp
二、配置过程
1、创建用户和用户组
[root@ ]# /usr/sbin/groupadd oinstall
[root@ ]# /usr/sbin/groupadd dba
创建Oracle用户和密码,输入命令:
[root@ ]# /usr/sbin/useradd -g oinstall -g dba -m oracle
[root@ ]# passwd oracle
2、创建数据库软件目录和数据文件存放目录
mkdir /home/oracle/app
mkdir /home/oracle/app/oracle
mkdir /home/oracle/app/oradata
mkdir /home/oracle/app/oracle/ product
更改目录属主为Oracle用户所有
chown -R oracle:oinstall /home/oracle/app
3、修改用户的SHELL的限制
修改/etc/security/limits.conf文件
输入命令:vi /etc/security/limits.conf,按i键进入编辑模式,将下列内容加入该文件。
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
编辑完成后按Esc键,输入 “:wq” 存盘退出
修改/etc/pam.d/login 文件,输入命令:vi /etc/pam.d/login,按i键进入编辑模式,将下列内容加入该文件。
session required /lib/security/pam_limits.so
session required pam_limits.so
编辑 /etc/profile ,输入命令:vi /etc/profile,按i键进入编辑模式,将下列内容加入该文件。
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
4、修改linux内核,修改/etc/sysctl.conf文件
输入命令: vi /etc/sysctl.conf ,按i键进入编辑模式,,将下列内容加入该文
件
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
要使 /etc/sysctl.conf 更改立即生效,执行以下命令
[root@ ]#/sbin/sysctl -p
5、配置oracle用户的环境变量
首先,切换到新创建的oracle用户下,
输入:su – oracle ,然后直接在输入 : vi .bash_profile
按i编辑 .bash_profile,进入编辑模式,增加以下内容:
umask 022
export ORACLE_BASE=/home/oracle/app
export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
编辑完成后按Esc键,输入 “:wq” 存盘退出
