After=network.target

[Service]

Type=simple

User=prometheus

ExecStart=/usr/local/bin/prometheus\

-- config.file=/etc/prometheus/prometheus.yml\

-- storage.tsdb.path=/var/lib/prometheus\

-- storage.tsdb.retention=15d\

-- web.read-timeout=5m\

-- web.max-connections=10\

-- query.max-concurrency=20\

-- query.timeout=2m\

-- web.enable-lifecycle

Restart=on-failure

[Install]

WantedBy=multi-user.target

Parameter explanation:

-- config.file=/etc/prometheus/prometheus.yml # prometheus profile

-- storage.tsdb.path=/var/lib/prometheus # prometheus storage data path

-- storage.tsdb.retention=15d # prometheus collection data retention time

-- web.read-timeout=5m # the maximum waiting time for requesting a link

-- web.max-connections=10 # maximum number of links

-- query.max-concurrency=20 # maximum number of concurrent queries supported

-- query.timeout=2m # timeout for a single query

-- web.enable-lifecycle # Hot load

5. Start

[root@localhost opt] # systemctl daemon-reload

[root@localhost opt] # systemctl enable prometheus

[root@localhost opt] # systemctl start prometheus

[root@localhost opt] # netstat-anlptu | grep: 9090

Deploy node_exporter

Node_exporter collects system data of machines. Here, exporter provided by prometheus is used. In addition to node_exporter, officials also provide exporter such as consul,memcached,haproxy,mysqld. For more information, please see the official website.

Here, the related services are deployed on the prometheus service and the node node.

Tar-zxvf node_exporter-0.17.0-rc.0.linux-amd64.tar.gz-C / usr/local/

Cd / usr/local/

Mv node_exporter-0.17.0-rc.0.linux-amd64 node_exporter

Set up users (nodes)

Groupadd prometheus

Useradd-g prometheus-s / sbin/nologin prometheus

Chown-R prometheus:prometheus / usr/local/node_exporter

[root@node1 ~] # vim / usr/lib/systemd/system/node_exporter.service
