zabbix 自动发现主机并关联模板

一.自动发现添加主机

1.利用agent自动发现主机

　　Configuration - Discovery -Create discovery rule

　　

2.将自动发现的主机关联模板

　　Configuration - Action -Event source:Discovery - Create action

 　　

 

3.查看发现主机结果

　　Monitoring - Discovery

　　
　　参考：https://blog.csdn.net/reblue520/article/details/52209755

 

 二.添加标准msyql监控模板

 1.拷贝模板配置文件

 

cp /root/zabbix-3.4.7/conf/zabbix_agentd/userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d

2.修改配置文件

 

　　原文件userparameter_mysql.conf 中的HOME目录是/var/lib/zabbix，也就是指向.my.cnf的目录，统一修改成自定义目录:/usr/local/zabbix/etc/
3.创建数据库连接账号

grant all on *.* to "mysqlcheck"@"localhost" identified by "mysqlcheck";
添加.my.cnf文件
[mysql]
host=localhost
user=mysqlcheck
password=mysqlcheck
socket=/usr/local/mysql/mysql.sock
[mysqladmin]
host=localhost
user=mysqlcheck
password=mysqlcheck
socket=/usr/local/mysql/mysql.sock
修改zabbix_agentd.conf，启用用户参数目录
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

4.重启agent

5..在server中将主机加入模板：Template DB MySQL

 

 　　

 　　

三.导入percona的mysql模板

1.安装配置percona监控

　　1)YUM安装

wget https://www.percona.com/downloads/percona-monitoring-plugins/percona-monitoring-plugins-1.1.8/binary/redhat/7/x86_64/percona-zabbix-templates-1.1.8-1.noarch.rpm

 

　　2)查看解压目录

[root@slave01 ~]# rpm -qpl percona-zabbix-templates-1.1.8-1.noarch.rpm
warning: percona-zabbix-templates-1.1.8-1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
/var/lib/zabbix/percona
/var/lib/zabbix/percona/scripts
/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh
/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
/var/lib/zabbix/percona/templates
/var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf
/var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml

　　2)将percona目录拷贝到zabbix目录

cp -rp /var/lib/zabbix/percona /usr/local/zabbix/etc/

　　3)zabbix_agentd.conf include上面的目录

　　4.重启agent
2.客户端agent主机配置
　　1)修改mysql连接信息

vim /usr/local/zabbix/etc/percona/scripts/ss_get_mysql_stats.php
$mysql_user = 'mysqlcheck';
$mysql_pass = 'mysqlcheck';

　　2)安装php

https://blog.csdn.net/zhezhebie/article/details/73325663
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum install php70w-cli php70w-mysql -y

　　3)测试脚本

[root@master scripts]# ./get_mysql_stats_wrapper.sh gg
14

　　4)在etc目录下配置.my.cnf

[client]
user = msyqlcheck
password = mysqlcheck

　　5)syql slave

[root@master etc]# sudo -u zabbix -H /usr/local/zabbix/etc/percona/scripts/get_mysql_stats_wrapper.sh running-slave
0

3.zabbix server配置

　　1)将templates的xml文件导入server
　　2)在agent或者server端都可以通过get来获取值
　　

/usr/local/zabbix/bin/zabbix_get -s 192.168.3.20 -k "MySQL.max-connections"

　　3)来源IP限制

28094:20180422:030055.200 failed to accept an incoming connection: connection from "127.0.0.1" rejected, allowed hosts: "192.168.3.2
Server=192.168.3.21,192.168.3.20,127.0.0.1
