改用户密码 password oracle 111111

===================================================================
基于Linux安装过Oracle的童鞋们都应该清楚,安装Oracle的确是一件比较费时费力的差事，因为仅仅是前期的rpm包，内核参数，创建用户等等这些个步骤都让那些新手不免眼花缭乱，一不留神，就导致最终的安装过程中报错而不得不从头来过。现在基于Oracle Linux，Oracle仅仅需要通过安装oracle-rdbms-server-11gR2-preinstall RPM包即可全部搞定其余未安装的RPM包，解决之间的依赖关系，配置内核参数等等。客官，正在基于Oracle Linux 安装Oralce 11g？那就接着往下看。

1、oracle-rdbms-server-11gR2-preinstall RPM 软件包的功能

a、 Automatically downloading and installing any additional software packages and specific package versions needed for installing Oracle Grid Infrastructure and Oracle Database 12 c Release 1 (12.1) or 11g Release 2 (11.2.0.3), with package dependencies resolved via yum or up2date capabilities.



b、Creating the user oracle and the groups oinstall (for OraInventory) and dba (for OSDBA), which are used during database installation. (For security purposes, this user has no password by default and cannot log in remotely. To enable remote login, please set a password using the passwd tool.)



c、Modifying kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on.
   
d、Setting hard and soft shell resource limits in /etc/security/limits.conf, such as the locked-in memory address space, the number of open files, the number of processes, and core file size.



e、Setting numa=off in the kernel for x86_64 machines.



2、操作步骤
a、确保网络畅通，即可连接到Internet。
b、已经安装了yum包管理工具。
c、切换到目录 /etc/yum.repos.d/
d、获取配置文件并进行相应修改wget http://public-yum.oracle.com/public-yum-ol6.repo(所需安装版本项下字段enabled=0更改为enabled=1)
e、使用yum安装oracle-rdbms-server-11gR2-preinstall包(oracle-rdbms-server-11gR2-preinstall)
f、校验内核修改日志及原文件备份情况

3、实战演习
a、检查网络环境，确保网络畅通
[root@oel63 ~]# cat /etc/issue
Oracle Linux Server release 6.3
Kernel \r on an \m
[root@oel63 ~]# ping www.baidu.com
PING www.a.shifen.com (115.239.211.110) 56(84) bytes of data.
64 bytes from 115.239.211.110: icmp_seq=1 ttl=54 time=39.2 ms
64 bytes from 115.239.211.110: icmp_seq=2 ttl=54 time=42.2 ms



b、检查yum是否已安装
[root@oel63 ~]# rpm -qa | grep yum
yum-utils-1.1.30-14.el6.noarch
PackageKit-yum-plugin-0.5.8-20.0.1.el6.x86_64
yum-rhn-plugin-0.9.1-40.0.1.el6.noarch
yum-plugin-security-1.1.30-14.el6.noarch
yum-3.2.29-30.0.1.el6.noarch
PackageKit-yum-0.5.8-20.0.1.el6.x86_64
yum-metadata-parser-1.1.2-16.el6.x86_64



c、切换到目录 /etc/yum.repos.d/
[root@oel63 ~]# cd /etc/yum.repos.d/



d、获取配置文件并进行相应修改
[root@oel63 yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol6.repo

在机器上用yum安装软件时居然遇到找不到GPG密钥
warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
就在网上收解决办法，结果看到这篇文章
Oracle Database 11g Release 2 Installation on RHEL/CentOS 6.x/5.x/4.x（http://www.tecmint.com/oracle-database-11g-release-2-installation-in-linux/）
按照他的输入命令wget https://public-yum.oracle.com/public-yum-ol6.repo结果出错，然后我直接到public-yum.oracle.com这个网站进去看到这个http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6一点出来个和/etc/yum.repos.d这个目录下差不多的东西，我就直接在这个目录下建个文件RPM-GPG-KEY-oracle将哪个复制进去保存退出。在用yum是就不会出现这个错误了

我系统是centos6.4
