linux监控平台介绍
- 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
zabbix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，需要php和mysql支持
- 单server节点可以支持上万台客户端
- 最新版本3.4，官方文档https://www.zabbix.com/manuals
- 包含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 也叫web UI，在web界面下操作配置是zabbix简单易用的主要原因
- zabbix-proxy 可选组件，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
zabbix安装
- 官网下载地址 www.zabbix.com/download
- wget repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm，下载zabbix源并安装源,客户端也要安装
[[email protected] ~]# rpm -ivh zabbix-release-3.2-1.el7.noarch.rpm 警告：zabbix-release-3.2-1.el7.noarch.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID a14fe591: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:zabbix-release-3.2-1.el7 ################################# [100%] - 服务端安装zabbix
yum install -y zabbix-agent zabbix-get zabbix-server-mysql zabbix-web zabbix-web-mysql- 会连带安装httpd和php
- 如果mysql之前没有安装的话，需要根据lamp那一章的mysql安装方法安装mysql
- vim /etc/my.cnf //需要增加配置
character_set_server = utf8 - 重启mysqld服务后，进入mysql命令行，创建zabbix库和用户
mysql> create database zabbix character set utf8; Query OK, 1 row affected (0.34 sec) mysql> grant all on zabbix.* to ‘zabbix‘@‘127.0.0.1‘ identified by ‘s5381561‘; Query OK, 0 rows affected (0.05 sec) - 导入数据

如果有nginx服务需要先停掉并禁掉开机启动 [[email protected] ~]# systemctl stop nginx [[email protected] ~]# chkconfig nginx off [[email protected] ~]# systemctl start httpd [[email protected] ~]# systemctl enable httpd [[email protected] ~]# systemctl start zabbix-server [[email protected] ~]# systemctl enable zabbix-server [[email protected] ~]# ps aux |grep zabbix zabbix 2048 0.0 0.1 254588 3496 ?

- PHP option "date.timezone" unknown Fail提示时区不对
[[email protected] ~]# vim /etc/php.ini date.timezone = Asia/Shanghai [[email protected] ~]# systemctl restart httpd - 下一步，定义mysql信息和主机名，最后完成
- 默认用户名Admin 密码zabbix
- 进入后台第一件事情就是修改密码，改中文
- 在客户端上也需要下载zabbix的yum源
- yum install -y zabbix-agent
- vim /etc/zabbix/zabbix_agentd.conf //修改如下配置
Server=127.0.0.1修改为Server=192.168.21.128 //定义服务端的ip（被动模式） ServerActive=127.0.0.1修改为ServerActive=192.168.21.128 //定义服务端的ip（主动模式） Hostname=Zabbix server修改为Hostname=Zabbix server //这是自定义的主机名，一会还需要在web界面下设置同样的主机名 - 启动服务并开机启动
[[email protected] ~]# systemctl start zabbix-agent [[email protected] ~]# systemctl enable zabbix-agent Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.忘记Admin密码如何做
