[root@oracle11g ~]#
4.安装依赖包
[root@oracle11g ~]# yum install -y binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make numactl sysstat libXp unixODBC unixODBC-devel -y
[root@oracle11g ~]#
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 = 4127434752
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
[root@oracle11g ~]#
7.用户对shell的限制
[root@oracle11g ~]# vim /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
[root@oracle11g ~]#
8.添加用户登陆模块
[root@oracle11g ~]# vim /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so
[root@oracle11g ~]#
9.主机与IP地址解析
[root@oracle11g ~]# vim /etc/hosts
192.168.3.20 oracle11g
10.创建用户与用户组
[root@oracle11g ~]# groupadd -g 500 oinstall
[root@oracle11g ~]# groupadd -g 501 dba
[root@oracle11g ~]# groupadd -g 502 oper
[root@oracle11g ~]# useradd -u 500 -g oinstall -G dba,oper oracle
[root@oracle11g ~]# chown -R oracle:oinstall /home/oracle
[root@oracle11g ~]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: it is based on a dictionary word
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
[root@oracle11g ~]#
11.创建所需要要的目录和设置环境变量
[root@oracle11g ~]# mkdir -p /u01/oracle/product/11.2.0.1/db_1
[root@oracle11g ~]# chown -R oracle:oinstall /u01
[root@oracle11g ~]# vim /home/oracle/.bash_profile
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$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 +
access control disabled, clients can connect from any host
[root@oracle11g ~]# su - oracle
[oracle@oracle11g ~]$ unzip linux.x64_11gR2_database_1of2.zip
