oracle11g在centos64上的安装日志

1.安装必要的编译环境和包；
2.添加必要的用户和用户组
3.创建必要的目录
## 修改oracle配置文件，配置环境变量 ，注意以oracle身份执行
[oracle@localhost ~]$ vi .bash_profile
## 修改为如下结果：
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
ORACLE_BASE=/u01/app/home/oracle
ORACLE_HOME=$ORACLE_BASE/product/11g/db_1
ORACLE_SID=orcl
NLS_LANG=AMERICAN_AMERICA.UTF8

PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID NLS_LANG PATH

## 保存后，检查oracle用户的环境变量,oracle变量已经加入：
[oracle@localhost ~]$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/sbin:/sbin:/home/oracle/bin:/u01/app/home/oracle/product/11g/db_1/bin
## 创建oracle安装的目录，并赋予oracle用户写权限：
[root@localhost oracle]# mkdir -p /u01/app/oracle
## oracle及其组员可以读写/u01/app/oracle目录
[root@localhost oracle]# chown -R oracle:oinstall /u01/app/oracle
## 所以成员 可以执行oracle，但只有管理员root可以修改配置
[root@localhost oracle]# chmod -R 755 /u01/app/oracle

## 修改内核参数
[root@localhost oracle]# vi /etc/sysctl.conf

# Kernel sysctl configuration file for Red Hat linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0

# Controls the System request debugging functionality of the kernel
kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename
# Useful for debugging multi-threaded applications
kernel.core_uses_pid = 1

# Controls the use of TCP syncookies
net.ipv4.tcp_syncookies = 1

# Controls the maximum size of a message, in bytes
kernel.msgmnb = 65536

# Controls the default maxmimum size of a mesage queue
kernel.msgmax = 65536

# Controls the maximum shared segment size, in bytes
kernel.shmmax = 68719476736

# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4294967296

# custum define，以下是自定义参数
fs.file-max = 65535
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65535
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default =262144
net.core.wmem_max = 262144

## 修改权限参数：
[root@localhost oracle]# vi /etc/security/limits.conf

#
#

#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student – maxlogins 4

oracle soft nproc 2047
oracle hard nproc 16383
oracle soft nofile 1023
oracle hard nofile 65535

# End of file

## 修改登录参数
[root@localhost oracle]# vi /etc/pam.d/login

#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session include system-auth
session required pam_loginuid.so
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke

# custom define
session required /lib/security/pam_limits.so
session required pam_limits.so

## 激活上面的配置：
[root@localhost oracle]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
fs.file-max = 65535
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65535
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

## 复制oracle安装文件到临时目录
[root@localhost oracle]# cd /media
[root@localhost media]# ls
linux.x64_11gR2_
[root@localhost media]# cd ./linux.x64_11gR2_/
[root@localhost linux.x64_11gR2_]# ls
doc install response rpm runInstaller sshsetup stage welcome.html

[root@localhost media]# cp -R * /tmp/oracle
[root@localhost media]# ls /tmp/oracle
doc install response rpm runInstaller sshsetup stage welcome.html
## 赋予执行权限：
[root@localhost media]# chmod 755 -R /tmp/oracle
[root@localhost media]# ls -al /tmp/oracle
