Prometheus是一个时间序列数据库，常用于监控，下面我们在CentOS7上部署一个Prometheus软件。

第一步、创建Prometheus目录

mkdir /usr/local/prometheus

第二步、下载Prometheus文件包

cd /usr/local/src
#官方网站：https://prometheus.io/download/
https://github.com/prometheus/prometheus/releases/download/v2.9.1/prometheus-2.9.1.linux-amd64.tar.gz

第三步、解压缩

tar zxvf prometheus-2.9.1.linux-amd64.tar.gz
mv prometheus-2.9.1.linux-amd64 /usr/local/prometheus

第四步、创建Promethdus Systemd服务

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

[Service]
User=prometheus
Restart=on-failure

#Change this line if you download the
#Prometheus on different path user
ExecStart=/usr/local/prometheus/prometheus \
  --config.file=/usr/local/prometheus/prometheus.yml \
  --storage.tsdb.path=/usr/local/prometheus/data \
  --web.enable-admin-api

[Install]
WantedBy=multi-user.target
EOF

第五步、创建prometheus用户和组

groupadd prometheus
useradd -g prometheus prometheus
cd /usr/local/prometheus
chown -R prometheus.prometheus *

第六步、启动Prometheus服务

systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus

第七步、访问测试

curl http://localhost:9090

后续，请修改/usr/local/prometheus/prometheus.yml配置文件
