cp prometheuspackage/prometheus /usr/local/bin/
cp prometheuspackage/promtool /usr/local/bin/- 更改prometheus/promtool属主
chown prometheus:prometheus /usr/local/bin/prometheus
chown prometheus:prometheus /usr/local/bin/promtool- 将“consoles”和“console_libraries”目录从“prometheuspackage”复制到“/etc/prometheus文件夹”
cp -r prometheuspackage/consoles /etc/prometheus
cp -r prometheuspackage/console_libraries /etc/prometheus- 将所有权更改为Prometheus用户
chown -R prometheus:prometheus /etc/prometheus/consoles
chown -R prometheus:prometheus /etc/prometheus/console_libraries- 添加和修改Prometheus配置文件

# 将以下配置添加到该文件中
global:
scrape_interval: 10s
scrape_configs:
- job_name: 'prometheus_master'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9090']
# 更改文件的所有权

[Install]
WantedBy=multi-user.target- 重新加载systemd服务&启动
systemctl daemon-reload
# 启动
systemctl start prometheus
# 查看状态
systemctl status prometheus- 如果需要，添加防火墙规则
firewall-cmd --zone=public --add-port=9090/tcp --permanent
systemctl reload firewalld访问Prometheus Web界面
- 使用以下Url访问UI
http://Server-IP:9090/graph使用Prometheus监控Linux服务器
- 需要在Linux服务器上配置Prometheus node exporter
# 下载
wget https://github.com/prometheus/node_exporter/releases/download/v0.17.0/node_exporter-0.17.0.linux-amd64.tar.gz- 解压node_exporter并进行相关配置
tar -xvzf node_exporter-0.17.0.linux-amd64.tar.gz
# 为node_exporter创建用户
useradd -rs /bin/false nodeusr
# 移动二进制文件
