服务器监控搭建完成后涉及默认端口修改，如下

node_exporter 端口修改

#修改启动服务

vi /usr/lib/systemd/system/node-exporter.service

#增加 --web.listen-address=:8002

复制代码

[Unit]

Description=This is prometheus node exporter

After=node_exporter.service

[Service]

Type=simple

ExecStart=/usr/local/node_exporter/node_exporter --web.listen-address=:8002

ExecReload=/bin/kill -HUP

KillMode=process

Restart=on-failure

[Install]

WantedBy=multi-user.target

#刷新

systemctl daemon-reload

#重启

复制代码

systemctl stop node-exporter.service

systemctl start node-exporter.service

prometheus 端口修改

#修改启动服务

vi /usr/lib/systemd/system/prometheusd.service

#增加 --web.listen-address=:8001

复制代码

[Unit]

Description=Prometheus

[Service]

ExecStart=/usr/local/prometheus/prometheus --web.listen-address=:8001  --web.enable-lifecycle  --config.file=/usr/local/prometheus/prometheus.yml

Restart=on-failure

[Install]

WantedBy=multi-user.target

#刷新

systemctl daemon-reload

#重启

复制代码

systemctl stop prometheusd.service

systemctl start prometheusd.service

grafana默认端口修改

#修改grafana配置文件

vim /etc/grafana/grafana.ini

#修改默认端口3000->8000，

去掉；3000改8000

#重启

复制代码

systemctl stop grafana-server.service

systemctl start grafana-server.service

可能会涉及到开端口，比如

#开放8000端口

firewall-cmd --add-port=8000/tcp --permanent

#重启防火墙

firewall-cmd --reload
