前提条件:在安装Linux时最好安装上以下软件,否则在安装Oracle过程中不能通过先决条件检测。(在检测后也可以安装缺少的软件,但会由于软件之间的依赖关系,导致安装非常困难,,最坏条件下,导致系统重装)

1. 在root模式下修改内核参数
#vi /etc/sysctl.conf
在代码结尾添加如下代码:
fs.file-max = 6815744
kernel.shmmni = 4096
kernel.shmmax = 4294967295 #物理内存一半
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 = 10488576
fs.aio-max-nr = 10488576
保存并退出
#/sbin/sysctl –p 使修改生效
2. 为oracle用户设置shell限制
#vi /etc/security/limits.conf
在文件尾部添加下列代码:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle - nofile 1006154
保存退出
3. 在root模式下创建oracle用户和组
#groupadd oinstall
#groupadd dba
#groupadd oper
#useradd –g oinstall –G dba,oper oracle //增加了oracle用户
#passwd oracle (在下面出现的命令行中设置oracle账户口令)
4. 为安装oracle建立目录
#cd /home/oracle //转到oracle目录下
#mkdir app //建立app目录
#chown –R oracle:oinstall /home/oracle/app
#chmod –R 775 /home/oracle/app //赋予权限
5. 切换到oracle账户并为oracle用户设置环境变量
#su – oracle
$vi /home/oracle/.bash_profile
在文件中添加:
export ORACLE_BASE=/home/oracle/app
export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
export ORACLE_SID=orcl (自己定义的名称)
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_LANG="SIMPLIFIED CHINESE_CHINA".ZHS16GBK
保存退出
$source /home/oracle/.bash_profile 使其生效
6.重新启动操作系统:
# reboot (重新启动命令)
特别说明:因为安装Oracle软件时不可使用root(超级用户)来进行安装,只可以使用刚才新建的oracle用户来进行安装,请大家一定要注意!
7.通过FTP工具把oracle11g压缩包复制到oracle文件夹下面
8.在oracle模式下解压oracle11g压缩包
#unzip linux.x64_11gR2_database_1of2.zip –d /home/oracle
#unzip linux.x64_11gR2_database_2of2.zip –d /home/oracle
9.新开一个终端窗口,以root身份执行命令 #xhost +
10.然后回到oracle窗口
进入database目录
$cd /home/oracle/database
$./runInstaller
开始安装。剩下的安装步骤和在windows下一样。
到最后千万要执行最后两个命令。
