Pada kesempatan di hari ini , saya akan membahas cara Install grafana dan Prometheus di centos 7, grafana sendiri merupakan tools untuk monitoring resurce sebuah server .
Langsung saja kita mulai .
- Install Prometheus
- Membuat user
useradd --no-create-home -s /bin/false prometheus
- Membuat direktori
mkdir /etc/prometheus
mkdir /var/lib/prometheus
- membuat hak akses
chown prometheus:prometheus /etc/prometheus
chown prometheus:prometheus /var/lib/prometheus
- download dan konfig prometheus
wget https://github.com/prometheus/prometheus/releases/download/v2.13.1/prometheus-2.13.1.linux-amd64.tar.gz
tar xvzf prometheus-2.13.1.linux-amd64.tar.gz
mv prometheus-2.13.1.linux-amd64/* /var/lib/prometheus/
chown -R prometheus:prometheus /var/lib/prometheus
mv /var/lib/prometheus/prometheus.yml /etc/prometheus/
ln -s /var/lib/prometheus/prometheus /usr/local/bin/prometheus
- membuat service
nano /usr/lib/systemd/system/prometheus.service
[Unit]
Description=Prometheus
Wants=network-online.target
After=network-online.target
[Service]
User=prometheus
Group=prometheus
Type=simple
ExecStart=/usr/local/bin/prometheus \
--config.file /etc/prometheus/prometheus.yml \
--storage.tsdb.path /var/lib/prometheus/ \
--web.console.templates=/var/lib/prometheus/consoles \
--web.console.libraries=/var/lib/prometheus/console_libraries
[Install]
WantedBy=multi-user.target
- Start service
systemctl enable --now prometheus.service
systemctl status prometheus.service
systemctl start prometheus.service
2. Install Node exporter
- download dan config node exporter
wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz
tar xvf node_exporter-0.18.1.linux-amd64.tar.gz
mkdir -p /var/lib/prometheus/node_exporter
mv node_exporter-0.18.1.linux-amd64/* /var/lib/prometheus/node_exporter
chown -R prometheus:prometheus /var/lib/prometheus/node_exporter/
- membuat service
nano /usr/lib/systemd/system/node_exporter.service
[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target
[Service]
User=prometheus
ExecStart=/var/lib/prometheus/node_exporter/node_exporter
[Install]
WantedBy=default.target
- start service
systemctl enable --now node_exporter.service
systemctl status node_exporter.service
systemctl start node_exporter.service
3. Install Grafana
- repo
nano /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
yum makecache fast -y
- install grafana
yum install -y grafana
systemctl enable --now grafana-server.service
systemctl status grafana-server.service
- akses web grafana
http://ipaddr:3000
user : admin
pass : admin
4. Setting prometheus dan grafana
-- setting prometheus
nano /etc/prometheus/prometheus.yml
global:
scrape_interval: 15s
scrape_configs:
- job_name: 'prometheus'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9090']
- job_name: 'node_exporter'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9100']
- restart service
systemctl restart prometheus.service
- akses web
http://ipaddr:9090
http://ipaddr:9090/targets
-- setting grafana
- Add Data Source
Buka menu Configuration -> Data Source -> Add Data Source -> pilih prometheus
isi :
Url -> http://localhost:9090
basic auth -> enable -> isi user + pass grafana
-> save and test
