linux监控平台介绍
常见开源监控软件
- cacti、nagios、zabbix、smokeping、open-falcon等等
- cacti、smokeping偏向于基础监控，成图非常漂亮
- cacti、nagios、zabbix服务端监控中心，需要php环境支持，其中zabbix和cacti都需要mysql作为数据存储，nagios不用存储历史数据，注重服务或者监控项的状态，zabbix会获取服务或者监控项目的数据，会把数据记录到数据库里，从而可以成图
- open-falcon为小米公司开发，开源后受到诸多大公司和运维工程师的追捧，适合大企业，滴滴、360、新浪微博、京东等大公司在使用这款监控软件，值得研究
zabbixx监控介绍
- C/S架构，基于C++开发，监控中心支持web界面配置和管理
- 单server节点可以支持上万台客户端
- 官方文档https://www.zabbix.com/manuals
- 5个组件
- zabbix-server监控中心，接收客户端上报信息，负责配置、统计、操作数据
- 数据存储，存放数据，比如mysql
- web界面，也加web UI，在web界面下操作配置是zabbix简单易用的主要原因
- zabbix-proxy可选组建，它可以代替zabbix-server的功能，减轻server的压力
- zabbix-agent客户端软件，负责采集各个监控服务或项目的数据，并上报
安装zabbix
- 官网下载地址www.zabbix.com/download
- wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
- rpm -ivh zabbix-release-3.2-1.el7.noarch.rpm
- yum install -y zabbix-agent zabbix-get zabbix-server-mysql zabbix-web zabbix-web-mysql
- 会连带安装httpd和php
- vi /etc/my.cnf character_set_server=utf9
- 重启mysqld服务后，进入mysql命令行，创建zabbix库
- create database zabbix character set utf8;
- 再创建用户
- grant all on zabbix.* to 'zabbix'@'127.0.0.1' identified by 'user-zabbix';
- 导入数据
- cd /usr/share/doc/zabbix-server-mysql-3.2.7
- gzip -d create.sql.gz
- mysql -uroot -pxxx zabbix < create.sql
