5.修改内核参数

[root@oracle11g ~]# vim /etc/sysctl.conf

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 = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

[root@oracle11g ~]# sysctl -p

6.用户对系统资源的限制

[root@oracle11g ~]# vim /etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

7.用户对shell的限制

[root@oracle11g ~]# vim /etc/profile

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

8.添加用户登陆模块

[root@oracle11g ~]# vim /etc/pam.d/login

session required /lib/security/pam_limits.so

session required pam_limits.so

9.主机与IP地址解析

[root@oracle11g ~]# vim /etc/hosts

192.168.3.20 oracle11g

10.创建用户与用户组

[root@oracle11g ~]# groupadd -g 500 oinstall

[root@oracle11g ~]# groupadd -g 501 dba

[root@oracle11g ~]# groupadd -g 502 oper

[root@oracle11g ~]# useradd -u 500 -g oinstall -G dba,oper oracle

[root@oracle11g ~]# chown -R oracle:oinstall /home/oracle

[root@oracle11g ~]# passwd oracle

Changing password for user oracle.

New password:

BAD PASSWORD: it is based on a dictionary word

[root@oracle11g ~]# mkdir -p /u01/oracle/product/11.2.0.1/db_1

[root@oracle11g ~]# chown -R oracle:oinstall /u01

[root@oracle11g ~]# vim /home/oracle/.bash_profile

export ORACLE_BASE=/u01/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.1/db_1

export ORACLE_SID=orac11g

export PATH=$ORACLE_HOME/bin:$PATH

[root@oracle11g ~]# . /home/oracle/.bash_profile

12.解压oracle 11g软件并安装

[root@oracle11g ~]# xhost +

[root@oracle11g ~]# su - oracle

[oracle@oracle11g ~]$ unzip linux.x64_11gR2_database_1of2.zip

[oracle@oracle11g ~]$ unzip linux.x64_11gR2_database_2of2.zip
