Fi sii Awọn iwo, InfluxDB ati Grafana lati ṣetọju CentOS 7

ni ipo olupin wẹẹbu.

InfluxDB jẹ orisun ṣiṣi ati ipilẹ data jara ti iwọn fun awọn iṣiro, awọn iṣẹlẹ, ati awọn atupale akoko gidi.

Grafana jẹ orisun ṣiṣi, ẹya ti o jẹ ọlọrọ, ti o ni agbara, didara ati didara julọ, irinṣẹ agbelebu fun ibojuwo ati awọn atupale metric, pẹlu awọn dasibodu ti o lẹwa ati ti aṣa. O jẹ de facto sọfitiwia fun awọn atupale data.

Ninu àpilẹkọ yii, a yoo ṣalaye bi o ṣe le fi sori ẹrọ ati tunto Awọn iwoye, InfluxDB ati Grafana lati ṣe atẹle iṣẹ ti olupin CentOS 7 kan.

Igbesẹ 1: Fi sii Awọn iwo ni CentOS 7

1. Ibẹrẹ akọkọ nipa fifi ẹya iduroṣinṣin tuntun ti awọn kokan (v2.11.1) nipa lilo PIP. Ti o ko ba ni pip, fi sii bi atẹle, pẹlu awọn akọle Python ti o nilo fun fifi sori psutil.

# yum install python-pip python-devel

2. Lọgan ti o ba ni PIP ati awọn akọle Python, ṣiṣe aṣẹ atẹle lati fi sori ẹrọ ẹya iduroṣinṣin tuntun ti awọn oju ati ṣayẹwo ẹya naa.

# pip install glances
# glances -V

Glances v2.11.1 with psutil v5.4.7

Ni omiiran, ti o ba ti ni awọn iwo ti o ti fi sii tẹlẹ, o le ṣe igbesoke rẹ si ẹya tuntun nipa lilo pipaṣẹ atẹle.

# pip install --upgrade glances

3. Bayi o nilo lati bẹrẹ awọn oju nipasẹ systemd ki o le ṣiṣẹ bi iṣẹ kan. Ṣẹda ẹyọ tuntun nipa ṣiṣẹda faili ti a pe ni glances.service in/etc/systemd/system /.

# vim /etc/systemd/system/glances.service

Daakọ ati lẹẹ iṣeto ni atẹle ni glances.service faili. Awọn --config n ṣalaye faili atunto, aṣayan - okeere-influxdb sọ fun awọn oju lati gbe awọn iṣiro si okeere si olupin InfluxDB ati --disable-ip aṣayan mu module IP ṣiṣẹ.

5. Itele, o nilo lati ṣe igbasilẹ faili iṣeto glances ti a pese nipasẹ Olùgbéejáde nipa lilo pipaṣẹ wget bi o ti han.

6. Lati gbe awọn iṣiro Glances jade si ibi ipamọ data InfluxDB kan, o nilo Python InfluxdDB lib, eyiti o le fi sii nipa lilo pipaṣẹ pip.

# sudo pip install influxdb

`Igbesẹ 2: Fi InfluxDB sii ni CentOS 7`

7. Nigbamii ti, o nilo lati ṣafikun ibi ipamọ InfluxDB Yum lati fi sori ẹrọ vesrion tuntun ti package InfluxDB bi o ti han.

10. Nipa aiyipada, InfluxDB nlo ibudo TCP 8086 fun ibaraẹnisọrọ alabara olupin lori InfluxDB's HTTP API, o nilo lati ṣii ibudo yii ni ogiriina rẹ nipa lilo ogiriina-cmd.

11. Nigbamii, o nilo lati ṣẹda iwe data ni InfluxDB fun titoju data lati awọn oju. Aṣẹ influx eyiti o wa ninu awọn idii InfluxDB ni ọna ti o rọrun julọ lati ṣe pẹlu ibi ipamọ data. Nitorinaa ṣiṣẹ influx lati bẹrẹ CLI ati sopọ laifọwọyi si apẹẹrẹ InfluxDB agbegbe.
