Prometheus启动后，默认端口是9090.浏览器打开地址是http://127.0.0.1:9090/graph

操作系统Centos7以上配置自启动

cat >/etc/systemd/system/prometheus.service<<EOF
 [Unit]
Description=Prometheus Monitoring System
Documentation=Prometheus Monitoring System
 
[Service]
ExecStart=/usr/local/prometheus/prometheus \
  --config.file=/usr/local/prometheus/prometheus.yml \
  --storage.tsdb.path=/usr/local/prometheus/storage \
  --web.console.templates=/usr/local/prometheus/consoles \
  --web.console.libraries=/usr/local/prometheus/console_libraries \
  --storage.tsdb.retention.time=30d --web.listen-address=:9090
[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus
ps -ef|grep prometheus

4. grafana安装部署

下载grafana安装包 https://grafana.com/grafana/download

wget https://dl.grafana.com/oss/release/grafana-7.3.7-1.x86_64.rpm
yum install grafana-7.3.7-1.x86_64.rpm
rpm -ivh --nodeps grafana-7.3.7-1.x86_64.rpm
systemctl daemon-reload 
systemctl enable grafana-server
systemctl start grafana-server
ps -ef|grep grafana-server

浏览器打开grafana，默认端口是3000,默认账号和密码都是admin

登陆后，需要修改密码，如果需要映射互联网，请使用强密码，大小写字母+特殊符号+数字+8位以上。

添加数据源

点击主界面的“add data source”

选择prometheus

Dashboards页面选择“Prometheus 2.0 Stats”

Settings页面填写普罗米修斯地址并保存

切换到我们刚才添加的“Prometheus 2.0 Stats”即可看到整个监控页面，这里这个现实的本机的资源。

到这里prometheus+grafana监控就安装完成了。下面是进行配置服务器和中间件等监控了。

5. node_exporter监控linux服务器

下载安装包node_exporter-0.18.1.linux-amd64.tar.gz，上传到被监控服务器。在被监控的机器安装node-exporter，

tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/
mv node_exporter-0.18.1.linux-amd64 node_exporter
cat >start.node-exporter.sh<<EOF
/usr/local/node_exporter/node_exporter &
EOF
chmod 755 start.node-exporter.sh
./start.node-exporter.sh

这个被监控软件启动后，默认端口是9100 。如果需要修改端口，需要在启动脚本上添加参数。

cat >start.node-exporter.sh<<EOF
/usr/local/node_exporter/node_exporter --web.listen-address=':9001' &
EOF

这里的9001为我设定的指定端口，表示node-exporter的监听端口是9001

vi /etc/init.d/node
#!/bin/sh
#chkconfig: 2345 80 90
#
# Simple node_exporter init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
NODE_HOME=/usr/local/node_exporter
PIDNUM=`ps -ef|grep node_exporter |grep -v grep |awk '{print $2}'`
PID=`ps -ef|grep node_exporter |grep -v grep |awk '{print $2}' |wc -l`
case "$1" in
    start)
        if [ ${PID} -eq 1 ]
        then
                echo "node_exporter exists, process is already running or crashed"
        else
                echo "Starting node_exporter server..."
                su -l tomcat -c "nohup /usr/local/node_exporter/node_exporter --web.listen-address=:9100 >/dev/null 2>&1 &"
        fi
        ;;
    stop)
        if [ ${PID} -eq 0 ]
        then
                echo "node_exporter does not exist, process is not running"
        else
                kill -9 $PIDNUM
                echo "Stopping ..."
                echo "node_exporter stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac
chmod +x /etc/init.d/node
chkconfig --add node && chkconfig node on
chkconfig --list node
service node start
service node stop
ps -ef|grep node_exporter

操作系统Centos7以上配置自启动

cat >>/etc/systemd/system/node.service <<EOF
[Unit]
Description=Prometheus Monitoring System
Documentation=Prometheus Monitoring System
Requires=network-online.target
After=network.target
[Service]
ExecStart=/data/prometheus/node_exporter/node_exporter \
  --web.listen-address=:9100
[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable node
systemctl start node
ps -ef|grep node

启动被监控服务器的node-exporter后，需要到监控服务器的/usr/local/prometheus目录下去修改配置文件，将被监控服务器添加到监控端。配置文件名称为 prometheus.yml

打开配置文件，添加被监控服务器信息，这个是监控同一网段服务器的配置

- job_name: ‘web-41’
static_configs:
- targets: ['192.168.205.41:9100']
   labels:
 	  instance: ‘web-41’

这个是通过网闸监控内网服务的配置192.168.220.21为网闸ip。10.176.0.75为本机ip

- job_name: ‘10.176.0.75’
static_configs:
- targets: ['192.168.220.21:9001]
   labels:
 	  instance: ‘10.176.0.75’

6. 配置微信告警

（1）首先配置企业微信应用

首先注册企业微信，点击“我的企业”，登记“企业ID”

（2）然后添加需要告警推送的用户。并将监控项目进行分部门。

将对应的人员添加到相应的部门，并登记部门ID。

点击应用管理，选择创建应用。

选择应用logo，填写应用名称，选择对应部门。

创建好以后，点开应用，登记Agentid和Secret 。

7. alertmanager安装部署

（1）首先下载alertmanager-0.20.0.linux-amd64.tar.gz，将其上传监控服务器的/usr/local路径下解压，并将文件夹重命名为 alertmanager。

tar -zxvf alertmanager-0.20.0.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/
mv alertmanager-0.20.0.linux-amd64 alertmanager
vi alertmanager/alertmanager.yml
global:
  resolve_timeout: 5m
  wechat_api_url: 'https://qyapi.weixin.qq.com/cgi-bin/'
templates:
- '/usr/local/alertmanager/wechat.tmpl'
route:
  group_by: ['alertname']
  group_wait: 10s
  group_interval: 10s
  repeat_interval: 10m
  receiver: 'wechat'
receivers:
- name: 'wechat'
  wechat_configs:
  - corp_id: 'ww732'
    to_party: '4'
    agent_id: '100'
    api_secret: 'RXpJffF_l0'
    send_resolved: true
inhibit_rules:
- equal: ['alertname', 'cluster', 'service']
  source_match:
    severity: 'high'
  target_match:
    severity: 'warning'

（2）上传wechat.tmpl微信告警模版至/usr/local/alertmanager路径下，路径要与alertmanager.yml中的templates模块的路径保持一致。

{{ define "wechat.default.message" }}
{{ range $i, $alert :=.Alerts }}
===XX监控报警===
告警级别：{{ $alert.Labels.severity }}
告警类型：{{ $alert.Labels.alertname }}
故障主机: {{ $alert.Labels.instance }}
告警详情: {{ $alert.Annotations.description }}
触发时间: {{ $alert.StartsAt.Format "2006-01-02 15:04:05" }}
{{ end }}
{{ end }}

（3）配置服务启动脚本

配置启动脚本：

cat >start.alertmanager.sh<<EOF
/usr/local/alertmanager/alertmanager --config.file=/usr/local/alertmanager/alertmanager.yml --storage.path=/usr/local/alertmanager/data &
EOF
chmod 755 start.alertmanager.sh

操作系统CentOS7以上配置自启动服务：

cat >/etc/systemd/system/alertmanager.service<<EOF
[Unit]
Description=Alertmanager
After=network.target
[Service]
Type=simple
ExecStart=/usr/local/alertmanager/alertmanager \
--config.file=/usr/local/alertmanager/alertmanager.yml \
--storage.path=/usr/local/alertmanager/data
Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable alertmanager
systemctl start alertmanager
ps -ef|grep alertmanager

8. 配置prometheus.yml

vim /usr/local/prometheus/prometheus.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).
  query_log_file: /usr/local/prometheus/log/prometheus.log
# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - 10.255.2.38:9093
      # - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  - "/usr/local/prometheus/rules/*.yml"
  # - "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']
mkdir /usr/local/prometheus/log
mkdir /usr/local/prometheus/rules

上传node.yml文件到 /usr/local/prometheus/rules

systemctl restart prometheus

9. blackbox_exporter安装(linux-url监控)

（1）下载采集器软件包blackbox_exporter-0.16.0.linux-amd64.tar.gz

tar -zxvf blackbox_exporter-0.16.0.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/
mv blackbox_exporter-0.16.0.linux-amd64 blackbox_exporter
cd blackbox_exporter
cp blackbox.yml blackbox.yml.bak

配置启动脚本：

cat >start.blackbox_exporter.sh<<EOF
/usr/local/blackbox_exporter/blackbox_exporter --config.file=/usr/local/blackbox_exporter/blackbox.yml &
EOF
chmod 755 start.blackbox_exporter.sh

操作系统CentOS7以上配置自启动服务：

cat >/usr/lib/systemd/system/blackbox_exporter.service<<EOF
[Unit]
Description=blackbox_exporter
After=network.target
[Service]
ExecStart=/usr/local/blackbox_exporter/blackbox_exporter  \
         --config.file=/usr/local/blackbox_exporter/blackbox.yml
[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable blackbox_exporter.service
systemctl start blackbox_exporter.service
ps -ef|grep blackbox_exporter

（2）定义接口模块参数（仅适用于post，get请求无需进行此步）post请求添加方式（需要向开发索要body请求体，以及fail_if_body_not_matches_regexp状态返回码），编辑blackbox.yml文件，在modules模块下添加post请求的相关配置（对应post-blackbox.yml）。

vi /usr/local/blackbox_exporter/blackbox.yml
modules:
  monitor:   接口模块自定义，prometheus.yml会引用
    prober: http
    timeout: 15s
    http:
      preferred_ip_protocol: "ip4"
      method: POST
      headers:
        Content-Type: application/json;charset=UTF-8
      body:  '{"app_id":"1BQA48ETK00082","biz_content":"193D2752D9F1C6F50998617FCD0E8471331D79","enc_type":"AES","method":"ehc.ehealthcard.queryInfo","sign":"5D55D1D06B3EB630F","sign_type":"MD5","term_id":"301","timestamp":"1540614","version":"X.M.0.1"}'
      fail_if_body_not_matches_regexp:
        - "0000"

（3）get请求 直接在prometheus.yml上加，并修改blackbox-dis.yml文件添加相关url监控页面地址（对应get-blackbox-dis.yml，/usr/local/blackbox_exporter/blackbox.yml保持不变）

vi /usr/local/prometheus/prometheus.yml
  - job_name: "blackbox"
    metrics_path: /probe
    params:
      module: [http_2xx]
    file_sd_configs:
    - refresh_interval: 1m
      files:
      - "/usr/local/blackbox_exporter/blackbox-dis.yml"
    relabel_configs:
    - source_labels: [__address__]
      target_label: __param_target
    - target_label: __address__
      replacement: 10.255.2.38:9115
vi /usr/local/blackbox_exporter/blackbox-dis.yml
  - targets: ['http://192.168.0.41:8080/web']
    labels:
      instance: 'http://192.168.0.41:8080/web'
      tags: 'xx服务'
      product: 'web服务'

（4）将blackbox.yml（对应rules-blackbox.yml）文件上传到/usr/local/prometheus/rules/下

systemctl restart blackbox_exporter.service
systemctl restart prometheus

（5）上传dashboard json文件到grafana，http status overview-1591064596650.json 监控url

10. blackbox_exporter安装(windows-url监控)

解压该文件，并进入该文件夹，双击blackbox_exporter.exe即可

2、定义http post参数监控详见Linux环境安装的第二步

3、定义http get参数监控详见linux环境安装的第三步

4、上传blackbox.yml到rule文件夹下

5、启动blackbox并重新加载prometheus

重启blackbox和prometheus （关闭exe程序，再双击重启即可）

6、上传dashboard json文件到grafana，http status overview-1591064596650.json 监控url

11. 服务端口监控

（1）修改prometheus.yml配置文件，添加端口监控

vi /usr/local/prometheus/prometheus.yml
  - job_name: 'port_status'
    metrics_path: /probe
    params:
      module: [tcp_connect]
    static_configs:
    - targets: ['10.16.84.27:1344']
      labels:
        instance: '10.16.84.27'
        tags: 'ehcServer27'
        port: 1344
    - targets: ['10.16.84.28:1344']
      labels:
        instance: '10.16.84.28'
        tags: 'ehcServer28'
        port: 1344
    relabel_configs:
    - source_labels: [__address__]
      target_label: __param_target
    - source_labels: [__param_target]
      target_label: instance
    - target_label: __address__
      replacement: 10.255.2.38:9115

（2）上传port.yml到/usr/local/prometheus/rule，并修改rule下的blackbox.yml文件

vi /usr/local/prometheus/rule/blackbox.yml
    #expr: probe_success == 0
    expr: probe_success{job != 'port_status'} == 0

（3）上传dashboard json文件到grafana，服务监控展示面板-1600237804697.json 监控url性能
