执行安装脚本

~]# . zabbix_autoinstall.sh
Enter db_ip (172.16.%.%)> 172.16.%.%    #授权访问的ip地址范围
Enter db_root_password > 123456           #数据库root密码
Enter zabbix_dbuser > zbxuser
Enter zabbix_dbpassword >123456
Enter zabbix_version (3.x).*  > 3.4
Enter zabbix_subversion *.*.(x) > 1         #这里输入的是zabbix版本号为3.4.1
........

整个过程大概需要10-20分钟，最后出现安装完成
