最重要的是，下载并安装 Oracle 11g 数据库软件安装所需的多个软件包，同时解决软件包之间的依赖关系请注意，经过 Oracle 验证的 RPM 包可通过 Oracle Unbreakable Linux Network (ULN) 访问，这需要支持合同或从 Oracle 公共 yum 存储库访问。
首先，我们需要将 Linux 计算机配置为能够使用公司代理连接到互联网，我们通过编辑 /etc/profile.d/proxy.sh 文件以及一些环境变量（如 FTP_PROXY）来完成此操作和 HTTP_PROXY
导出 http_proxy=http://test-apache-001-dev.corporateict.domain:8123/
导出 ftp_proxy=http://test-apache-001-dev.corporateict.domain:8123/
导出 no_proxy=.corporateict.domain
导出 HTTP_PROXY=http://test-apache-001-dev.corporateict.domain:8123/
导出 FTP_PROXY=http://test-apache-001-dev.corporateict.domain:8123/
再次以 root 身份登录以调用对环境所做的更改。
然后，我们使用 wget 下载包含存储库位置的文件
[root@kens-orasql-001 yum.repos.d]# wget http://public-yum.oracle.com/public-yum-el5.repo
我们必须更新此文件，并将适用于我们的 Linux 版本的标记的启用=0 行更改为启用=1 – 在我们的例子中，我们使用的是 OEL 5.7，因此我们必须更新这些行：
改变
[ol5_u7_base]
name=Oracle Linux $releasever – U7 – $basearch – base
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL5/7/base/$basearch/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
gpgcheck=1
启用=0
到
[ol5_u7_base]
name=Oracle Linux $releasever – U7 – $basearch – base
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL5/7/base/$basearch/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
gpgcheck=1
启用=1
然后我们运行 yum update，然后运行 yum install oracle-validated

[root@kens-orasql-002 yum.repos.d]#
我们可以看到oracle验证的RPM已经安装了。
[root@kens-orasql-001 yum.repos.d]# <strong>rpm -qa |grep oracle-valid</strong> oracle-validated-1.1.0-14.el5
我们还可以检查并查看用户和组是否也已创建。
[root@kens-orasql-001 yum.repos.d]# <strong>cat /etc/passwd |grep oracle</strong> oracle:x:54321:54321::/home/oracle:/bin/bash [root@kens-orasql-001 yum.repos.d]# <strong>cat /etc/group |grep dba </strong> dba:x:54322:oracle
它还更新了 /etc/security/limits.conf 文件
[root@kens-orasql-001 yum.repos.d]# cat /etc/security/limits.conf # Oracle-Validated setting for nofile soft limit is 131072 oracle soft nofile 131072 # Oracle-Validated setting for nofile hard limit is 131072 oracle hard nofile 131072 # Oracle-Validated setting for nproc soft limit is 131072 oracle soft nproc 131072 # Oracle-Validated setting for nproc hard limit is 131072 oracle hard nproc 131072 # Oracle-Validated setting for core soft limit is unlimited oracle soft core unlimited # Oracle-Validated setting for core hard limit is unlimited oracle hard core unlimited # Oracle-Validated setting for memlock soft limit is 50000000 oracle soft memlock 50000000 # Oracle-Validated setting for memlock hard limit is 50000000 oracle hard memlock 50000000
最后，我们可以看到 /etc/sysctl.conf 也已更新，并添加了一些“Oracle-Validated”设置。
