[root@localhost opt]# systemctl daemon-reload

[root@localhost ~]# systemctl start Prometheus

5 访问web

(本地ip:9090)

点击Status—Target 可以看到Prometheus的metrics

目前看到的只是Prometheus的一些监控项，我们一下安装一些插件来完成系统监控项的一些收集

2 安装node-exporter

[root@localhost opt]# wget

[root@localhost opt]# tar zxf node_exporter-0.18.1.linux-amd64.tar.gz

[root@localhost opt]# cd node_exporter-0.18.1.linux-amd64/

ExecStart=/opt/node_exporter-0.18.1.linux-amd64/node_exporter

Restart=on-failure

[Install]

WantedBy=multi-user.target

[root@localhost opt]# systemctl daemon-reload

3 修改权限

[root@localhost opt]# chown prometheus:prometheus -R ./node_exporter-0.18.1.linux-amd64

[root@localhost ~]# systemctl start node_exporter

4 添加prometheus的job

[root@localhost prometheus-2.13.1.linux-amd64]# cat 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).

# 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=` to any timeseries scraped from this config.

- job_name: 'prometheus'

# metrics_path defaults to '/metrics'

# scheme defaults to 'http'.

static_configs:

- targets: ['192.168.135.240:9090']

- job_name: 192.168.135.240_centos

static_configs:

- targets: ['192.168.135.240:9100']

labels:

instance: 192.168.135.240_centos

##此部分为新加的nodxexporter的地址信息nodeexporter的默认端口是9100

5 重启prometheus

[root@localhost prometheus-2.13.1.linux-amd64]# systemctl restart prometheus

可以看到nodeexporter的信息已经发送到了prometheus，为了更好的展示我们收集到的监控信息安装grafana

6 grafana

Dashboard https://grafana.com/api/dashboards/10645/revisions/1/download

3 安装grafana

1 下载软件

[root@localhost opt]# wget

[root@localhost opt]# tar zxf grafana-6.4.3.linux-amd64.tar.gz

3 启动服务

[root@localhost system]# systemctl daemon-reload

[root@localhost system]# systemctl start grafana

4 访问web

http:192.168.135.240:3000(本地ip:3000) 用户名密码admin：admin

1 添加数据源

Configuration---Add data source

因为我们的数据是prometheus所以此处选择prometheus

2 添加dashboard

这里可以添加一写系统自带的prometheus的dashboard但是只可以看到prometheus的一些监控信息

3下载其他dashboard模板

下载好模板后再Dashboars – Manage 选择import 将文件导入

导入后就可以看到我们新加的模板，点击他就可以看到监控页面了

注：如果页面上又报错说grafana-piechart-panel不存在那么就安装他

[root@localhost bin]# ./grafana-cli plugins install grafana-piechart-panel

installing grafana-piechart-panel @ 1.3.9

from: https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.3.9/download

into: /var/lib/grafana/plugins

✔ Installed grafana-piechart-panel successfully

Restart grafana after installing plugins . <service>

[root@localhost bin]# systemctl restart grafana

4 安装mysqld_exporter

3 修改权限创建user

mysql> create user jian@'%' identified by '123456';

Query OK, 0 rows affected (0.02 sec)

mysql> grant replication client,process on *.* to jian@'%';

Query OK, 0 rows affected (0.01 sec)

mysql> grant select on performance_schma.* to jian@'%';

[root@localhost opt]# chown prometheus:prometheus -R ./mysqld_exporter-0.12.1.linux-amd64 [root@localhost opt]# systemctl daemon-reload

[root@localhost opt]# systemctl start mysqld_exporter

4 添加prometheus的job

[root@localhost prometheus-2.13.1.linux-amd64]# cat prometheus.yml

- job_name: 192.168.135.236_mysql

static_configs:

- targets: ['192.168.135.236:9104']

labels:

instance: 192.168.135.236_mysql

##此部分为新加的mysqldxexporter的地址信息mysqldexporter的默认端口是9104

5 重启prometheus

[root@localhost prometheus-2.13.1.linux-amd64]# systemctl restart prometheus
