基於http://www.cnblogs.com/netonline/p/7406598.html（http://blog.chinaunix.net/uid-26168435-id-5730201.html），寫了1個簡單的指令碼來簡化zabbix_agnetd的部署。
指令碼運行注意事項：
1. script與zabbix-3.0.1.tar.gz放置在同一個目錄運行；
2. 由於zabbix安裝檔案的名字未採用變數，在script中已寫死，雖然可變更，但需要同步修改腳其中對應的地方；
3. script中涉及到變更運行目錄，所以請使用"source" 或 ". "運行script，如: "source xx.sh"或". ./xx.sh"；
4. script運行基於centos6.x，請注意與centos7.x的命令區別，這裡主要是centos7.x預設沒有iptables，需要提前準備好iptables的環境。
