簡單說明：

依據《CentOS7實驗機模板搭建部署》克隆實驗機192.168.77.210，部署Zabbix 3.0 LTS
配置郵件告警功能，配置自動發現功能，配置action對發現的主機自動監控並郵件告警

部署安裝Zabbix 3.0 LTS：

# 主機名和hosts解析部署
HOSTNAME=zabbix
hostnamectl set-hostname "$HOSTNAME"
echo "$HOSTNAME">/etc/hostname
echo "$(grep -E '127|::1' /etc/hosts)">/etc/hosts
echo "$(ip a|grep "inet "|grep -v 127|awk -F'[ /]' '{print $6}') $HOSTNAME">>/etc/hosts

# 安裝MySQL
yum -y install mariadb-server mariadb
systemctl restart mariadb
systemctl enable mariadb

# 使用官方yum源安裝Zabbix
# https://www.zabbix.com/download?zabbix=3.0&os_distribution=centos&os_version=7&db=MySQL
cd /tmp
axel https://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
rpm -ivh /tmp/zabbix-release-3.0-1.el7.noarch.rpm
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

# 建庫，匯入zabbix庫
mysql
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to 
 
[email protected] identified by 'zabbix';
flush privileges;
quit;
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -pzabbix zabbix

# 修改配置檔案，啟動
sed -i 's/# DBPassword=.*/&\nDBPassword=zabbix/g' /etc/zabbix/zabbix_server.conf
sed -i 's|# \(php_value date.timezone\) Europe/Riga|\1 Asia/Shanghai|g' /etc/httpd/conf.d/zabbix.conf
systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd
# 網頁配置 http://192.168.77.210/zabbix
# 預設使用者名稱和密碼 Admin/zabbix
 

配置郵件告警功能：

配置自動發現功能並測試：

1° 依據《CentOS6實驗機模板搭建部署》克隆測試機 192.168.77.250 並部署：

# 主機名和hosts解析部署
hostname zabbixtest
echo "$(grep -E '127|::1' /etc/hosts)">/etc/hosts
echo "$(ifconfig eth0|grep inet|awk -F'[ :]' '{print $13}') $(hostname)">>/etc/hosts
echo "192.168.77.210 zabbix_server">>/etc/hosts
sed -i "s/^HOSTNAME.*$/HOSTNAME=$(hostname)/g" /etc/sysconfig/network
ping -c 3 $(hostname)

# 使用官方yum源安裝配置Zabbix agent
cd /tmp
wget https://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm
rpm -ivh /tmp/zabbix-release-3.0-1.el6.noarch.rpm
yum -y install zabbix-agent
cd /etc/zabbix/
sed -i 's/^Server=127.0.0.1/Server=zabbix_server/g' zabbix_agentd.conf
sed -i 's/^ServerActive=127.0.0.1/ServerActive=zabbix_server:10051/g' zabbix_agentd.conf
sed -i "s/^\(Hostname=\).*/\1$(hostname)/g" zabbix_agentd.conf
chkconfig zabbix-agent on
/etc/init.d/zabbix-agent start
 

2° 網頁新增自動發現功能
Configuration——>Discovery——>Create discovery rule

Monitoring>Discovery——>Status of discovery

配置Action自動新增OS並郵件告警：

Configuration——>Actions——>Event source: Discovery——>Create action


此處可以看出，可以依據下線狀態的主機進行操作，比如刪除掉下線主機
