# 安装Prometheus Server

Prometheus基于Golang编写，编译后的软件包，不依赖于任何的第三方依赖。用户只需要下载对应平台的二进制包，解压并且添加基本的配置即可正常启动Prometheus Server。

## 从二进制包安装

对于非Docker用户，可以从<https://prometheus.io/download/>找到最新版本的Prometheus Sevrer软件包：

```
export VERSION=2.4.3
curl -LO  https://github.com/prometheus/prometheus/releases/download/v$VERSION/prometheus-$VERSION.darwin-amd64.tar.gz
```

解压，并将Prometheus相关的命令，添加到系统环境变量路径即可：

```
tar -xzf prometheus-${VERSION}.darwin-amd64.tar.gz
cd prometheus-${VERSION}.darwin-amd64
```

解压后当前目录会包含默认的Prometheus配置文件promethes.yml:

```
# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']
```

Promtheus作为一个时间序列数据库，其采集的数据会以文件的形式存储在本地中，默认的存储路径为`data/`，因此我们需要先手动创建该目录：

```
mkdir -p data
```

用户也可以通过参数`--storage.tsdb.path="data/"`修改本地数据存储的路径。

启动prometheus服务，其会默认加载当前路径下的prometheus.yaml文件：

```
./prometheus
```

正常的情况下，你可以看到以下输出内容：

```
level=info ts=2018-10-23T14:55:14.499484Z caller=main.go:554 msg="Starting TSDB ..."
level=info ts=2018-10-23T14:55:14.499531Z caller=web.go:397 component=web msg="Start listening for connections" address=0.0.0.0:9090
level=info ts=2018-10-23T14:55:14.507999Z caller=main.go:564 msg="TSDB started"
level=info ts=2018-10-23T14:55:14.508068Z caller=main.go:624 msg="Loading configuration file" filename=prometheus.yml
level=info ts=2018-10-23T14:55:14.509509Z caller=main.go:650 msg="Completed loading of configuration file" filename=prometheus.yml
level=info ts=2018-10-23T14:55:14.509537Z caller=main.go:523 msg="Server is ready to receive web requests."
```

## 使用容器安装

对于Docker用户，直接使用Prometheus的镜像即可启动Prometheus Server：

```
docker run -p 9090:9090 -v /etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
```

启动完成后，可以通过<http://localhost:9090>访问Prometheus的UI界面：
