需求：
· grafana版本要和grafana-zabbix版本對應，避免異常
· 更新時，須要二者同步更新

1. CentOS安裝grafana（rpm）

# wget https://grafanarel.s3.amazonaws.com/builds/grafana-2.5.0-1.x86_64.rpm
# rpm -ivh grafana-2.5.0-1.x86_64.rpm
#或者直接使用
# yum install https://grafanarel.s3.amazonaws.com/builds/grafana-2.5.0-1.x86_64.rpm

· 環境變量：/etc/sysconfig/grafana-server
· 配置文件：/etc/grafana/grafana.ini
· 日誌文件：/var/log/grafana/grafana.log
· systemd服務：grafana-server.service
· sqlite3數據庫：/var/lib/grafana/grafana.db
· grafana安裝目錄：/usr/share/grafana
服務詳情
· 啓動用戶：grafana
· 服務名稱：grafana-server
· 默認端口：3000
· 帳號：admin
· 密碼：admin

1.1 yum安裝

# vim /etc/yum.repos.d/grafana.repo
[grafana]
name=grafana
baseurl=https://packagecloud.io/grafana/stable/el/6/$basearch  #穩定版
#baseurl=https://packagecloud.io/grafana/testing/el/6/$basearch #最新版（beta）
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packagecloud.io/gpg.key https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

啓動服務/開機自啓

C6# service grafana-server start
C6# chkconfig --add grafana-server
C6# chkconfig grafana-server on
C7# systemctl daemon-reload
C7# systemctl start grafana-server
C7# systemctl enable grafana-server.service

查看狀態

C7# systemctl status grafana-server

1.2 升級

# yum install initscripts fontconfig
# rpm -Uvh grafana-3.1.0-1468321182.x86_64.rpm

2. 安裝grafana-zabbix插件

# wget https://github.com/alexanderzobnin/grafana-zabbix/archive/v2.5.1.tar.gz
# tar xzf v2.5.1.tar.gz
# cp -r grafana-zabbix-2.5.1/zabbix /usr/share/grafana/public/app/plugins/datasource/
# cd /usr/share/grafana/public/app/plugins/datasource/zabbix
# vim plugin.json
{
  "pluginType": "datasource",
  "name": "Zabbix",

  "type": "zabbix",
  "serviceName": "ZabbixAPIDatasource",

  "module": "app/plugins/datasource/zabbix/datasource",

  "partials": {
    "config": "app/plugins/datasource/zabbix/partials/config.html"
  },

# 追加"username"和"password"內容。用戶並不是必定是管理員，只要有可讀權限便可。
  "username": "Admin",
  "password": "zabbix",

  "metrics": true,
  "annotations": true
}

測試用戶/密碼是否正確

# curl -i -X POST -H 'Content-Type:application/json' -d '{"jsonrpc": "2.0","method":"user.authenticate","params":{"user":"Admin","password":"zabbix"},"auth": null,"id":0}' http://127.0.0.1/api_jsonrpc.php

修改Zabbix的API文件，因爲Zabbix2.2不支持跨域的問題，故添加如下配置：（2.4之後無需配置）

require_once dirname(__FILE__).'/include/func.inc.php';
require_once dirname(__FILE__).'/include/classes/core/CHttpRequest.php';

在上面兩行前新增

# vim <wwwroot>/zabbix/api_jsonrpc.php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
    return;
}
