grafana使用mysql存储

序

默认grafana使用sqlite3进行相关配置存储，使用本地文件进行session存储，不太方便进行分布式扩展，这里改为mysql。

修改配置文件

[database]
; Either "mysql", "postgres" or "sqlite3", it's your choice
type = mysql
host = 192.168.99.100:3306
name = grafana
user = root
password = root

[session]
provider = mysql
provider_config = root:root@tcp(192.168.99.100:3306)/grafana
cookie_name = grafana_session
cookie_secure = false
session_life_time = 86400

配置mysql

docker run --name grafana-mysql -e MYSQL_ROOT_PASSWORD=root -p 3306:3306 -d mysql:5.6.35

CREATE DATABASE IF NOT EXISTS grafana default charset utf8 COLLATE utf8_general_ci;

CREATE TABLE `session` (
    `key`       CHAR(16) NOT NULL,
    `data`      BLOB,
    `expiry`    INT(11) UNSIGNED NOT NULL,
    PRIMARY KEY (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

运行

查看表结构：

mysql> use grafana;
Query OK, 0 rows affected (0.00 sec)

mysql> show tables;
