一键准备Oracle安装
在Linux下安装Oracle软件之前,有相当工作需要准备,包括建立用户、配置内核参数、配置资源限制参数、配置Oracle用户环境等,十分繁琐。即便十分熟悉,也需要花费一定的精力来准备。说白了,做这些事情有点类似于低水平重复建设,虽没有多大技术含量,却又不得不做。现在将这些准备工作做成脚本,这样可以近乎实现一键准备Oracle安装。
说明:
1> 该脚本的执行方式为sh Oracle_Setup_Prepare.sh orcl /u01,两个参数说明见脚本解释部分。
2> 该脚本中涉及到一个文本文件Package_list,是Oracle安装依赖包的列表。具体内容如下文所示。
3> 该脚本主要针对于单实例数据库安装。
4> 安装信息可参考生成的output.log文件
脚本内容如下:
[oracle@node3 ~]$ cat Oracle_Setup_Prepare.sh

PS: 既然sed每次都是在最后一行追加,其实,用echo "***" >> filename即可实现。
