## 部署grafana组件
### 解压grafana组件到指定目录
```
# 解压
tar xzvf grafana-7.4.0.linux-amd64.tar.gz -C /data/applications/prometheus
# 创建软连接
ln -s grafana-7.4.0 grafana
```
### 创建文件夹
```
# 进入文件夹
cd /data/applications/prometheus/grafana
# 创建文件夹
mkdir data logs dashboards script
```
### 配置grafana.ini文件
```
#################################### Paths ####################################
[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
# use "cfg:default.paths.data" to specified via command line
data = /data/applications/prometheus/grafana/data
#
# Directory where grafana can store logs
# use "cfg:default.paths.logs" to specified via command line
logs = /data/applications/prometheus/grafana/logs
#
# Directory where grafana will automatically scan and look for plugins
# use "cfg:default.paths.plugins" to specified via command line
plugins = /data/applications/prometheus/grafana/plugins
#################################### Server ####################################
[server]
# Protocol (http or https)
;protocol = http
;The ip address to bind to, empty will bind to all interfaces
;http_addr = 192.168.70.133
# The http port to use, defaults to 3000
http_port = 3000
# The public facing domain name used to access grafana from a browser
domain = 192.168.70.133
# Redirect to correct domain if host header does not match domain
# Prevents DNS rebinding attacks
;enforce_domain = false
# The full public facing url
;root_url = http://localhost:3000/grafana/
root_url = %(protocol)s://%(domain)s/grafana/
# Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons.
serve_from_sub_path = true
```
### 创建run\_grafana.sh启动文件
```
cd /data/applications/prometheus/grafana/script
vim run_grafana.sh
```
```
#!/bin/bash
set -e
DEPLOY_DIR=/data/applications/prometheus/grafana/
cd "${DEPLOY_DIR}" || exit 1
exec /data/applications/prometheus/grafana/bin/grafana-server --config=/data/applications/prometheus/grafana/conf/grafana.ini 2>&1 &
```
### 登录grafana
```
http://192.167.70.133:3000/grafana
默认用户名与密码都是admin,首次登陆后，需要对admin的密码进行修改
```
### 选择您的配置选项
```
Grafana后端在其配置文件中定义了许多配置选项（通常在Linux系统上位于/etc/grafana/grafana.ini中）。
在此配置文件中，您可以更改默认管理员密码，http端口，grafana数据库（sqlite3，mysql，postgres），身份验证选项（google，github，ldap，auth proxy）以及许多其他选项。
启动您的grafana服务器。用您的管理员用户登录（默认为admin / admin）。打开侧面菜单（单击顶部菜单中的Grafana图标），转到数据源，然后添加数据源。
```
### 添加Prometheus的数据源。
第一步：添加数据源
第二步：设置数据源、数据源名称、类型、IP地址、端口号…
在grafana中导入相关json文件
导入的是MySQL\_Overview.json
其他的json文件导入也是类似的。
