zabbix_server的自動發現，實現批量添加主機，並鏈接到模板

一、需求

　　zabbix 服務器可以手動加入zabbix-agent客戶端，對於少量的機器，這沒有什么。但到了線上，我們有大量的服務器需要監控時，如果再一個個的手動加的話，工作量勢必會增加很多。這時，zabbix-server 的Discovery 自動發現功能便派上了用場。

二、條件

　　1.zabbix server 已經部署好，所需要加入的服務器zabbix-agent已經安裝。

　　2.防火牆都開放端口，主要是10050、10051端口，或者關閉整個iptables

三、zabbix-agent客戶端的設置

　　1.打開zabbix-agent.conf配置文件，只需要修改2處配置.大批量的修改，可以利用自動化部署工具、如saltstack、ansible等。我用的是saltstack推送文件的方式進行修改，在本實驗環境中，我用的是國產的一個批量工具CheungSSH。

　　2.批量執行的命令

sed -i 's/Server=127.0.0.1/Server=10.8.0.22/g' /etc/zabbix/zabbix_agentd.conf sed -i 's/ServerActive=127.0.0.1/ServerActive=10.8.0.22/g' /etc/zabbix/zabbix_agentd.conf grep "Server" /etc/zabbix/zabbix_agentd.conf | grep -v '^#' service zabbix-agent restart

　　上述命令完成后，要在zabbix-server上創建discover規則

四、zabbix-server 登陸web界面進行設置,創建規則，並自動加入，自動鏈接模板

　　1.Configuration-->Discovery-->Create discovery rule

下面是創建規則時的具體參數，來自官網：

Parameter	Description
Name	Unique name of the rule. For example, “Local network”.
Discovery by proxy	What performs discovery: no proxy - Zabbix server is doing discovery <proxy name> - this proxy performs discovery
IP range	The range of IP addresses for discovery. It may have the following formats: Single IP: 192.168.1.33 Range of IP addresses: 192.168.1-10.1-255. The range is limited by the total number of covered addresses (less than 64K). IP mask: 192.168.4.0/24 supported IP masks: /16 - /30 for IPv4 addresses /112 - /128 for IPv6 addresses List: 192.168.1.1-255, 192.168.2.1-100, 192.168.2.200, 192.168.4.0/24 Since Zabbix 3.0.0 this field supports spaces, tabulation and multiple lines.
Delay (in sec)	This parameter defines how often Zabbix will execute the rule. Delay is measured after the execution of previous discovery instance ends so there is no overlap.
Checks	Zabbix will use this list of checks for discovery. Supported checks: SSH, LDAP, SMTP, FTP, HTTP, HTTPS, POP, NNTP, IMAP, TCP, Telnet, Zabbix agent, SNMPv1 agent, SNMPv2 agent, SNMPv3 agent, ICMP ping. A protocol-based discovery uses the net.tcp.service[] functionality to test each host, except for SNMP which queries an SNMP OID. Zabbix agent is tested by querying an item. Please see agent items for more details. The 'Ports' parameter may be one of following: Single port: 22 Range of ports: 22-45 List: 22-45,55,60-70
Device uniqueness criteria	Uniqueness criteria may be: IP address - no processing of multiple single-IP devices. If a device with the same IP already exists it will be considered already discovered and a new host will not be added. Type of discovery check - either SNMP or Zabbix agent check.
Enabled	With the check-box marked the rule is active and will be executed by Zabbix server. If unmarked, the rule is not active. It won't be executed.
