范围：
Since it is the expressed goal to keep Oracle Linux (OL) functionally IDENTICAL to RHEL，
本文也完全适用于 64-bit (x86-64) OL 7.0 (or higher 7.x version).

• 快速搭建Linux操作系统+Oracle数据库环境 
• RedHat 5.5下安装Oracle 10g+RAC 
• 在CentOS 6.4下安装Oracle 11gR2(x64)
• Oracle 11gR2 在VMWare虚拟机中安装步骤

细节：
installing Oracle 11gR2 RDBMS release 11.2.0.4 64-bit on RHEL7 or OL7 64-bit (x86_64)的安装需求如下

I. 硬件：
 1. 最低硬件需求
    a)至少1GB物理内存
    b)swap满足下面的要求：
 

      注意： 上面的推荐（来自于 11.2 Database installation guide）是最低的推荐。
    c)/tmp至少1GB空间，并且要少于2TB空间。
    d)database software 至少需要4.4GB空间
    e)database 需要至少1.7G空间。
  2. Oracle database 在 ext2，ext3，ext4 和 xfs文件系统上受到支持（参见Note:236826.1 and Note 1632127.1 以获得更多信息）
 
II软件：
 1. As is specified in section 1.3.2 of the Oracle Database Installation Guide for 11gR2 on Linux (part number E24321-02), Oracle recommends that you install the Linux operating system with the default software packages (RPMs) and do not customize the RPMs during installation. For additional information on "default-RPMs", please see Note 376183.1, "Defining a "default RPMs" installation of the RHEL OS" or Note 401167.1, "Defining a "default RPMs" installation of the Oracle Enterprise Linux (OEL) OS".
 2. Red Hat Enterprise Linux Server 7.0 (or higher 7.x version) or Oracle Linux 7.0 (or higher 7.x version)
  注意：RHEL7 servers must be running Red Hat kernel 3.10.0-54.0.1.el7 (x86_64) or higher or 3.8.13-33.el7uek (x86_64) or higher with UEK kernel.
        OL7 servers must also be running kernel 3.8.13-33.el7uek (x86_64) or higher version. The product RHEL does not deliver UEK Kernel.
        Only in OL 7 UEK and RHCK Kernel is included.
 
 3. 需要的os 组件
  a) The exact version number details of this list are based upon 64-bit (x86_64) RHEL 7.0. When a higher "update" level is used, the RPM release numbers (such as 4.4.4-13) may be slightly different. Since updates of RHEL 7 are certified, this is fine so long as you are still using 64-bit Linux (x86_64) RHEL 7 RPMs.
  b) Some of the Install Guide requirements will already be present from the "default-RPMs" foundation of Linux that you started with: 

binutils-2.23.52.0.1-12.el7.x86_64
compat-libcap1-1.10-3.el7.x86_64
gcc-4.8.2-3.el7.x86_64
gcc-c++-4.8.2-3.el7.x86_64
glibc-2.17-36.el7.i686
glibc-2.17-36.el7.x86_64
glibc-devel-2.17-36.el7.i686
glibc-devel-2.17-36.el7.x86_64
ksh
libaio-0.3.109-9.el7.i686
libaio-0.3.109-9.el7.x86_64
libaio-devel-0.3.109-9.el7.i686
libaio-devel-0.3.109-9.el7.x86_64
libgcc-4.8.2-3.el7.i686
libgcc-4.8.2-3.el7.x86_64
libstdc++-4.8.2-3.el7.i686
libstdc++-4.8.2-3.el7.x86_64
libstdc++-devel-4.8.2-3.el7.i686
libstdc++-devel-4.8.2-3.el7.x86_64
libXi-1.7.2-1.el7.i686
libXi-1.7.2-1.el7.x86_64
libXtst-1.2.2-1.el7.i686
libXtst-1.2.2-1.el7.x86_64
make-3.82-19.el7.x86_64
sysstat-10.1.5-1.el7.x86_64

 4. Additional Required OS Components (per the runInstaller OUI)
    a) intentionally blank
     
  5. Additional Required OS Components (per this NOTE)
    a)请不要仓促（rush），跳过（skip）,最小化（minimize）这个关键步骤。这个list基于64bit的 "default-RPMs"的安装。
    Additional RPMs (beyond anything known to Oracle) may be needed if a "less-than-default-RPMs" installation of 64-bit (x86_64) RHEL Server 6 is performed. For more information, please refer to Note 376183.1, "Defining a "default RPMs" installation of the RHEL OS" or Note 401167.1, "Defining a "default RPMs" installation of the Oracle Enterprise Linux (OEL) OS".
    b)一些RPM包是需要作为上面RPM包列表的预先要求的RPM包：

cpp-4.8.2-16.el7.x86_64
glibc-headers-2.17-55.el7.x86_64
mpfr-3.1.1-4.el7.x86_64

  6. Oracle 全球客户支持（GCS）已经注意到最近的趋势，该趋势是起源于安装了太多的rpm包的而导致的问题，举例：
      a.) installing your own JDK version (prior to execute the Oracle Software runInstaller) is not needed on Linux, and is not recommended on Linux. A pre-existing JDK often interferes with the correct JDK that the Linux Oracle Software runInstaller will place and use.
      b.) installing more than the required version of the gcc / g++ RPMs often leads to accidentally using (aka enabling or activating) the incorrect one. If you have multiple RDBMS versions installed on the same Linux machine, then you will likely have to manage multiple versions of gcc /g++ . For more information, please see Note 444084.1, "Multiple gcc / g++ Versions in Linux"
  7. 在II中所有的RPM包都在Red Hat Enterprise Linux 7 64-bit (x86_64)发行版介质中。
