zabbix_agentd-install.sh (脚本部署zabbix_agentd服务)分分

基于（卡塔尔，写了1个简单的脚本来简化zabbix_agnetd的部署。
本子运维注意事项：

script与zabbix-3.0.1.tar.gz放置在同叁个目录运维；
2. 由于zabbix安装文件的名字未使用变量，在script中已写死，即使可转移，但须要一齐修正脚中间对应之处；
script中关系到改造运转目录，所以请使用"source" 或 ". "运营script，如: "source xx.sh"或". ./xx.sh"；
4. script运维基于centos6.x，请小心与centos7.x的命令分歧，这里根本是centos7.x暗中认可未有iptables，必要提前盘算好iptables的情状。
