基于http://www.cnblogs.com/netonline/p/7406598.html（http://blog.chinaunix.net/uid-26168435-id-5730201.html），写了1个简单的脚本来简化zabbix_agnetd的部署。
脚本运行注意事项：
1. script与zabbix-3.0.1.tar.gz放置在同一个目录运行；
2. 由于zabbix安装文件的名字未采用变量，在script中已写死，虽然可变更，但需要同步修改脚其中对应的地方；
3. script中涉及到变更运行目录，所以请使用"source" 或 ". "运行script，如: "source xx.sh"或". ./xx.sh"；
4. script运行基于centos6.x，请注意与centos7.x的命令区别，这里主要是centos7.x默认没有iptables，需要提前准备好iptables的环境。
