一键自动安装zabbix

ywg

　　最近对bash shell比较感兴趣，刚好也在看zabbix相关的东西，就整了一个自动安装的脚本，安装完就可以直接配置zabbix，比较省事。以后想要再次安装，上传相关软件到服务器，刷一下脚本即可，非常方便。
　　本方案采用：MySQL + libgd + Apache + php + zabbix ，经本人实验，该自动安装脚本可用。
　　#环境介绍
　　系统版本：centos7.1
　　相关软件：apr-1.5.2、apr-util-1.5.4 、httpd-2.4.7、libgd-2.1.0、mysql-5.6.26、pcre-8.34、php-    5.6.14、zabbix-2.4.6
　　以下为bash shell脚本：
#!/bin/bash
#定义全局变量
#因为采用通配符的方式，模式匹配apr的时候会匹配到apr-util，所以需要做个特殊处理，因此定义了两个数组，一个为需要安装的软件名称，一个是特殊处理的软件名称。
install_list=("libgd" "mysql" "httpd" "apr" "apr-util" "php" "zabbix" "pcre")
special_list=("apr")
#定义全局路径
storage_path=/usr/local/src
unzip_path=$storage_path/unzip_soft
mysql_prefix=/usr/local/mysql
libgd_prefix=/usr/local/libgd
httpd_prefix=/usr/local/apache
php_prefix=/usr/local/php
zabbix_prefix=/usr/local/zabbix
