grafana是什么？

1）grafana是用于可视化大型测量数据的开源程序，他提供了强大和优雅的方式去创建、共享、浏览数据。dashboard中显示了你不同metric数据源中的数据。
2）grafana最常用于因特网基础设施和应用分析，但在其他领域也有机会用到，比如：工业传感器、家庭自动化、过程控制等等。
3）grafana有热插拔控制面板和可扩展的数据源，目前已经支持Graphite、InfluxDB、OpenTSDB、Elasticsearch。

安装，配置Grafana软件

1，安装grafana软件
[grafana官网安装说明](http://docs.grafana.org/installation/rpm/）
我们这里介绍5.1.4版本的grafana的安装，如果需要其他版本请点击上述连接到官网自行下载安装

sudo yum install https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.1.4-1.x86_64.rpm
//granfan软件的目录结构
/usr/sbin/grafana-server 安装的二进制文件，可执行的命令
/etc/sysconfig/grafana-server 默认和软件相关的环境变量
/etc/grafana/grafana.ini  默认的配置文件
/var/log/grafana/grafana.log 默认的日志文件
/var/lib/grafana/grafana.db 默认使用的时候是sqlite3数据库，里面存放的连接信息，刚安装好服务没启动之前这个文件是不存在的
systemctl start grafana-server.service  //启动服务
systemctl enable grafana-server.service //把服务加入开机启动文件中

说明：

1，默认是以grafana用户来启动grafana的，默认监听在3000端口。
2，默认的登录用户是admin/admin
3，我们可以通过http://IP:3000来访问grafana的web界面
4，默认使用的数据库是sqlite3

登录上去之后的默认页面

2，配置grafana软件
1）/etc/sysconfig/grafana-server 环境变量配置文件说明

[root@zabbix grafana]# cat /etc/sysconfig/grafana-server
GRAFANA_USER=grafana
 // 启动grafana的用户身份
GRAFANA_GROUP=grafana
// 启动grafana的用户组身份
GRAFANA_HOME=/usr/share/grafana
// garfana软件默认的目录
LOG_DIR=/var/log/grafana
// grafana日志文件存放的位置
DATA_DIR=/var/lib/grafana
// grafana默认数据存放的位置，sqlite3数据库
MAX_OPEN_FILES=10000
// 最大打开的文件数
CONF_DIR=/etc/grafana
// 默认配置文件存在的目录
CONF_FILE=/etc/grafana/grafana.ini
// 默认的配置文件
RESTART_ON_UPGRADE=true
// 从新启动升级开启
PLUGINS_DIR=/var/lib/grafana/plugins
// 插件存放的目录
PROVISIONING_CFG_DIR=/etc/grafana/provisioning

# Only used on systemd systems
PID_FILE_DIR=/var/run/grafana
// 软件启动pid号存放的在那个文件中

// 我们更改上述信息重启grafana生效

2）解读/etc/grafana/grafana.ini默认的配置文件，优先级高于上个文件

这个文件中 ; 代表注释，注释的值代表默认的值
[root@zabbix /]# cat /etc/grafana/grafana.ini

用户认证方式的位置：garfana几种用户认证方式

3）修改配置文件

// grafana默把数据存在sqlite3里，我们更改到mysql重
[root@zabbix /]# grep "^[a-z]" /etc/grafana/grafana.ini
domain = test.garfana.com
root_url = http://test.garfana.com:3000
type = mysql
host = 172.16.1.51:3306
name = grafana
user = grafana
password = "zsf123.com"
log_queries =
admin_user = zsf
admin_password = "zsf123.com"

4）mysql创建库和用户并授权

MariaDB [(none)]> create database grafana ;
MariaDB [(none)]> grant all privileges on grafana.* to grafana@"172.16.1.71" identified by 'zsf123.com';
MariaDB [(none)]> flush privileges;

5）重启grafana使其配置生效，登录web界面连接配置，安装Plugin插件

通过grafana与zabbix的配合使用来介绍grafana的使用方式

1）安装zabbix插件，进入grafana-web首页---> install apps & Plugin安装zabbix插件

选择Zabbix插件

[root@zabbix /]#
[root@zabbix /]# grafana-cli plugins install alexanderzobnin-zabbix-app
installing alexanderzobnin-zabbix-app @ 3.9.1
from url: https://grafana.com/api/plugins/alexanderzobnin-zabbix-app/versions/3.9.1/download
into: /var/lib/grafana/plugins

✔ Installed alexanderzobnin-zabbix-app successfully

Restart grafana after installing plugins . 
// 安装完插件之后重启一下grafana端
[root@zabbix /]# systemctl restart grafana-server.service

2）然后进入到web首页点击

进入启用zabbix插件

3）添加一个报表的数据源

4）查看模版的信息
到首页点击home

5）指定义指示盘

先创建一个garfana的行来归类

创建一个图表




大概页面就是这么一个情况，

添加一个饼图插件
和安装Zabbix插件是一样的过程

grafana-cli plugins install grafana-piechart-panel
installing grafana-piechart-panel @ 1.3.3
from url: https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.3.3/download
into: /var/lib/grafana/plugins

✔ Installed grafana-piechart-panel successfully

Restart grafana after installing plugins . 
[root@zabbix /]# systemctl restart grafana-server.service

安装完成之后就能在添加模块的地方看到饼图了，即可创建，内存的饼图

安装插件介绍到这，基本使用已经能正常了，后期继续推出相关教程
