三件套：influxdb telegraf grafana
infuluxdb
下载安装
wget https://dl.influxdata.com/influxdb/releases/influxdb-1.2.2.x86_64.rpm yum localinstall influxdb-1.2.2.x86_64.rpm
修改配置：
vim /etc/influxdb/influxdb.conf reporting-disabled = true #bind-address = ":8086" [admin] # Determines whether the admin service is enabled. enabled = true （web管理界面) bind-address = ":8083" （web服务界面的端口）
开机启动
systemctl start influxdb systemctl enable influxdb
进入db
influx # 进入控制台，创建个db试试 create database test_db show databases; name: databases name ---- _internal test_db
搞定。 注意： influxdb的数据文件
/var/log/influxdb/influxd.log 日志文件 /var/lib/influxdb/data 数据文件 /var/cache/yum/influxdb 缓存处理数据 记得挂盘或者ln -s
telegraf
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.3.0-1.x86_64.rpm yum localinstall telegraf-1.3.0-1.x86_64.rpm ## 编辑，配置 vi /etc/telegraf/telegraf.conf # 查找influx，修改influx的上报端口 [[outputs.influxdb]] ## The HTTP or UDP URL for your InfluxDB instance. Each item should be ## of the form: ## scheme "://" host [ ":" port] ## ## Multiple urls can be specified as part of the same cluster, ## this means that only ONE of the urls will be written to each interval. # urls = ["udp://localhost:8089"] # UDP endpoint example urls = ["http://localhost:8086"] # required ## The target database for metrics (telegraf will create it if not exists). database = "telegraf" # required # 打开注释，监控k8s [[inputs.kubernetes]] # ## URL for the kubelet url = "http://localhost:10255" systemctl start telegraf systemctl enable telegraf systemctl status telegraf
grafana
wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.4.0-1.x86_64.rpm yum localinstall grafana-5.4.0-1.x86_64.rpm systemctl daemon-reload systemctl start grafana-server systemctl status grafana-server systemctl enable grafana-server.service
编辑配置：
vim /etc/grafana/grafana.ini # 把3000端口改成你要的
打开web页，用默认账户登录，添加源
配置telegraf监控
进入 https://grafana.com/dashboards/928 按它的配置，修改telegraf的配置。 下载json文件，进入new dashboard，然后导入这个json。 简直吊爆了。
