1. 下载安装介质

  • 计划telegraf和influxdb 使用rpm包进行安装。Grafana使用docker容器方式安装
下载路径为：
https://repos.influxdata.com/rhel/7Server/x86_64/stable/
其实可以根据仓库自己查找就可以了。
拉取镜像为：
docker pull grafana/grafana 
注意2021.8时的版本信息为：
influxdb-1.8.9.x86_64.rpm
telegraf-1.19.2-1.x86_64.rpm
grafana 8.1的版本
注意 influxdb2的版本变化比较大 资料比较少一些。

2. 安装介质

yum localinstall *.rpm 
需要注意的是,设置为开机启动相关。

3. influxdb参数文件设置

  • influxdb的设置
  • 注意安装完之后需要启动数据库
  • systemctl enable influxdb && systemctl restart influxdb 启动数据库即可。
注意可以通过influx 命令登录进数据库，一开始设置完没有密码可以直接登录，但是用有密码之后必须使用命令进行登录了。
influxdb 是一个时序数据库可以通过telegraf 等工具push监控数据进来，然后交由grafana进行图形化展示。
# 显示用户
SHOW USERS
# 创建用户
CREATE USER "username" WITH PASSWORD 'password'
# 赋予用户管理员权限
GRANT ALL PRIVILEGES TO username
# 创建管理员权限的用户
CREATE USER <username> WITH PASSWORD '<password>' WITH ALL PRIVILEGES
# 修改用户密码
SET PASSWORD FOR username = 'password'
# 撤消权限
REVOKE ALL ON mydb FROM username
# 查看权限
SHOW GRANTS FOR username
# 删除用户
DROP USER "username"
  • 注意设置好权限之后就可以进行telegraf的处理了。

4. telegraf的配置文件

    • systemctl enable influxdb && systemctl restart influxdb 启动数据库即可。
vim /etc/telegraf/vm187.conf
添加内容为：
[global_tags]
[agent]
interval = "10s"
round_interval = true
metric_batch_size = 1000
metric_buffer_limit = 10000
collection_jitter = "0s"
flush_interval = "10s"
flush_jitter = "0s"
precision = ""
hostname = ""
omit_hostname = false
[[outputs.influxdb]]
#这里需要修改。
urls = ["http://127.0.0.1:8086"]
database = "vm187"
timeout = "0s"
username = "influxdb"
password = "上一步创建的密码"
[[inputs.vsphere]]
# 这里需要设置为密码
  vcenters = [ "https://yourvmcenterip/sdk" ]
  username = "administrator@vsphere.local"
  password = "yourvcenterpassword"

   ]
cluster_metric_include = [] 
datastore_metric_include = [] 
  datacenter_metric_include = []
  datacenter_metric_exclude = [ "*" ] 
insecure_skip_verify = true
  • 设置完之后需要启动telegraf
nohup telegraf -config /etc/telegraf/vm187.conf & 
后台运行即可。
  • 注意我设置的是最小化的参数。

5. docker 运行grafana

docker run -d   -p 3000:3000   --name=grafana   -v /opt/grafana-storage:/var/lib/grafana   grafana/grafana
注意需要进行持久化避免重启之后数据丢失

6.添加influxdb 的数据源

注意需要输入创建的用户和密码
端口选择为8086

7. 添加grafana的json文件或者是执行导入即可。
