Ubuntu 16.04 - Zabbix Agent 部署脚本：脚本里设置了 ServerActive ，会主动尝试到zabbix server注册，但需要先在zabbix frontend的 configuration->actions->auto registration 配置好 add host 动作，这样才会自动添加。

zabbix-agent-setup.sh

#!/bin/bash

set -x

ZABBIX_SERVER=192.168.1.100

wget http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.2-1+xenial_all.deb
dpkg -i zabbix-release_3.2-1+xenial_all.deb
apt update
apt -y install zabbix-agent

ip=`ifconfig  | grep -o 'inet addr:172\.[0-9.]*' | awk -F: '{print $2}'`
sed -i \
    -e 's/^Server=.*$/Server='$ZABBIX_SERVER'/' \
    -e 's/^ServerActive=.*$/ServerActive=lan.zabbix.thebitplus.com/' \
    -e 's/^Hostname=.*$/Hostname='`hostname`'/' \
    /etc/zabbix/zabbix_agentd.conf

sudo update-rc.d zabbix-agent enable
sudo service zabbix-agent restart

echo "Done"
