基于文章http://blog.chinaunix.net/uid-26168435-id-5728816.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,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。
