influxdb
添加源
cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
[influxdb]
name = InfluxDB Repository - RHEL \$releasever
baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key
EOF
安装
yum -y install influxdb
设置用户名密码
influx
CREATE USER "root" WITH PASSWORD 'root' WITH ALL PRIVILEGES
注：先设置用户名密码再改如下配置，因为涉及auth-enabled = true
vim /etc/influxdb/influxdb.conf
[http]下
enabled = true
bind-address = ":8086"
auth-enabled = true
[Http]模块上方加入
[admin]
# 是否启用该模块，默认值 ： false
enabled = true
# 绑定地址，默认值 ：":8083"
bind-address = ":8083"
启动
systemctl start influxdb
接口进行访问
curl -G http://localhost:8086/query --data-urlencode "q=show databases"
开机启动
systemctl enable influxdb
卸载
yum -y remove influxdb
备份出配置文件
mkdir /opt/influxdb-docker/
cp /etc/influxdb/influxdb.conf /opt/influxdb-docker/
用于下篇docker
telegraf
前面安装influxdb时已经添加了源
yum -y install telegraf
修改配置
vim /etc/telegraf/telegraf.conf
[[outputs.influxdb]]模块下
解锁urls = ["http://127.0.0.1:8086"]
解锁database = "telegraf"
解锁timeout = "5s"
若influxdb设置了auth-enabled = true，这里需要设置用户名密码
username = "root"
password = "root"
配置官方文档见：https://docs.influxdata.com/telegraf
设置后auth-enabled=true后在linux操作influx需要用户名密码，命令为auth
influx
auth
show databases
先运行influxdb
然后启动telegraf
systemctl start telegraf
启用
systemctl enable telegraf
查看运行状态
systemctl status telegraf
卸载
yum -y remove telegraf
备份出配置文件
mkdir /opt/telegraf-docker/
cp /etc/telegraf/telegraf.conf /opt/telegraf-docker/
用于下篇docker
grafana
添加源
见https://grafana.com/docs/installation/rpm/
cat <<EOF | sudo tee /etc/yum.repos.d/grafana.repo
[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packages.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
EOF
yum -y install grafana
启动
systemctl start grafana-server
启用
systemctl enable grafana-server
卸载
yum -y remove grafana-server
进入网站 用户名密码都是admin
第一步创建datasource
Name为telegraf与上面telegraf配置的数据库名一致
influxdb开启了auth-enabled = true
需要勾选Basic Auth 数据库用户名密码都是root

后面的dashboard随意了，记得在sql语句中选择表和列，部分列可以按*显示，否则不会展示数据。
