安装Prometheus

官网下载地址,获取最新下载URL.

#切换到root用户
sudo -i

#下载prometheus二进制压缩包,可以自定义版本
wget https://github.com/prometheus/prometheus/releases/download/v2.37.6/prometheus-2.37.6.linux-amd64.tar.gz

#解压
tar xf prometheus-2.37.6.linux-amd64.tar.gz

#查看解压后的文件名
ls -l

mkdir /opt/prometheus -p

#移动解压后的文件名到/opt/，并改名prometheus
mv prometheus-2.37.6.linux-amd64/ /opt/prometheus/prometheus

创建一个专门的`prometheus`用户：

useradd -M -s /usr/sbin/nologin prometheus

更改prometheus用户的文件夹权限：

chown prometheus:prometheus -R /opt/prometheus

创建 systemd 服务

cat > /etc/systemd/system/prometheus.service << "EOF"
[Unit]
Description=Prometheus Server
Documentation=https://prometheus.io/docs/introduction/overview/
After=network-online.target

[Service]

  --config.file=/opt/prometheus/prometheus/prometheus.yml \
  --storage.tsdb.path=/opt/prometheus/prometheus/data \
  --storage.tsdb.retention.time=60d \
  --web.enable-lifecycle

--web.enable-lifecycle                                                  #热加载

启动 Prometheus

systemctl daemon-reload
systemctl staadmin prometheus.service
systemctl status prometheus.service
systemctl enable prometheus.service

下载aleadminmanager二进制压缩包
wget https://github.com/prometheus/aleadminmanager/releases/download/v0.25.0/aleadminmanager-0.25.0.linux-amd64.tar.gz

#解压
tar xf aleadminmanager-0.25.0.linux-amd64.tar.gz

#查看解压后的文件名

systemctl status aleadminmanager.service

检查配置

cd /opt/prometheus/prometheus/
./promtool check config prometheus.yml

重启prometheus或重新加载配置文件（二选一）

#重启
systemctl restaadmin prometheus
或：
#重载，需要--web.enable-lifecycle配置，热加载
