写给自己：linux运维路，自己动手趟一遍
参考：http://www.cnblogs.com/yingsong/p/6031235.html
----------------------------
准备工作：
内存及swap要求
1-2G物理内存时 swap是1.5倍
2-16G物理内存时 swap相等
大于16G物理内存时 swap 16G
硬盘空间 >20G
关闭防火墙及SELINUX
修改内核参数：
修改用户限制文件
#vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 102405创建用户及组
#groupadd dba #useradd -m -g dba oracle #passwd oracle创建安装目录
#mkdir -p /ora11/product/11.2.0/db_1数据文件存放目录
#mkdir -p /ora11/oradata数据恢复目录
#mkdir -p /ora11/recovery_data数据库创建及使用过程中的日志目录
#mkdir -p /ora11/oraInventory修改安装目录权限
#chown -R oracle:dba /ora11 #chmod -R 775 /ora11登录oracle用户，设置环境变量
#su - oracle $vim .bash_profileexport ORACLE_BASE=/ora11 export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64 export ORACLE_SID=rac1 export PATH=$PATH:$ORACLE_HOME/bin$source .bash_profile //使设置生效安装依赖包
自己整理了一下(全部在这里了）
---------------------------------------
将安装包上传到oracle用户的home目录

/database/response/db_install.rsp 安装应答配置文件
/database/response/dbca.rsp 创建数据库应答
/database/response/netca.rsp 建立监听、本地服务名等网络设置应答
修改配置文件db_install.rsp，并安装 (实例名为rac1,密码为12345678)
登录oracle用户，执行安装
#su - oracle $./runInstaller -silent -ignorePrereq -responseFile /home/oracle/database/response/db_install.rsp其中-silent指的是静默安装，-ignorePrereq忽略prerequisite的检查结果，responseFile是安装文件。
安装过程中，如果提示[WARNING]不必理会，此时安装程序仍在进行，如果出现[FATAL]，则安装程序已经停止了。
打开另一个终端，执行命令
可以实时跟踪查看安装日志，了解安装的进度。

出错后，需要删除已经创建的目录，再次安装
