摘要: 这几天,要将生产上正在使用的应用做成自动化安装的脚本,我分配的任务是nginx自动化安装。由于nginx之前有写过,所以利用这次机会,就写了一个nginx+tomcat+resin+jdk一键自动化安装的脚本

思路:用户执行父shell,父shell匹配用户输入的信息,相应地去执行子shell。

    话不多说,直接看shell。

├── auto_install.sh                ----父shell
├── install_jdk.sh                 ----子shell--jdk安装   
├── install_mysql.sh               ----子shell--mysql安装
├── install_nginx.sh               ----子shell--nginx安装
├── install_resin.sh               ----子shell--resin安装
├── install_tomcat.sh              ----子shell--tomcat安装
├── log                     ----日志输出目录       
├── pkgs                    ----压缩包目录
├── replace_file            ----替换文件目录
└── tmp                     ----临时文本目录

以上是脚本的目录层级关系。下面我将逐一介绍。

首先,介绍父shell----auto_install.sh

#!/bin/bash
#this shell is used to automatically install software
#by wangjiulong
#自动安装程序

#global variables      -----全局变量
export pwd_dir=/data/scripts/auto_install_pkgs
export tar_dir=$pwd_dir/pkgs
export file_dir=$pwd_dir/replace_file
export log_dir=$pwd_dir/log
export log=$log_dir/log.log

export tmp_dir=$pwd_dir/tmp
export tmp_jdk=$tmp_dir/tmp_jdk.txt
export tmp_jdk_version=$tmp_dir/tmp_jdk_version.txt
export tmp_resin=$tmp_dir/tmp_resin.txt
export tmp_tomcat=$tmp_dir/tmp_tomcat.txt
export tmp_mysql=$tmp_dir/tmp_mysql.txt
export tmp_bak=$tmp_dir/tmp_bak.txt

export tmp_nginx_local=$tmp_dir/tmp_nginx_local.txt
export tmp_nginx_local_version=$tmp_dir/tmp_nginx_local_version.txt
export tmp_nginx_pkgtar=$tmp_dir/tmp_nginx_pkgtar.txt

show_tar

以上,就是父shell的全部内容,父shell主要的作用如下:

        1、为每台服务器预先安装rpm包。

        2、展示脚本中支持自动化安装的tar包

        3、判断用户输入信息,并与shell脚本中保存的信息匹配,然后调用匹配成功的tar包的安装shell脚本。
