tar xvf prometheus-2.38.0.linux-amd64.tar.gz
ln -s prometheus-2.38.0.linux-amd64 prometheus

二.安装 node_exporter 

在被监控机器上下载 node_exporter

wget https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz
tar xvf node_exporter-1.3.1.linux-amd64.tar.gz
ln -s node_exporter-1.3.1.linux-amd64 node_exporter

启动 node_exporter

nohup ./node_exporter  --web.listen-address=":9100"&
netstat -ntlup | grep 9100

三.安装 mysqld_exporter 

在被监控机器上下载 mysqld_exporter

wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.14.0/mysqld_exporter-0.14.0.linux-amd64.tar.gz
tar xvf mysqld_exporter-0.14.0.linux-amd64.tar.gz
ln -s mysqld_exporter-0.14.0.linux-amd64 mysqld_exporter

创建监控⽤户

create user 'monitor'@'127.0.0.1' identified with mysql_native_password by '123456';
grant select,replication client, process on *.* to 'monitor'@'127.0.0.1';

添加客户端账号

vim /usr/local/mysqld_exporter/.my.cnf[client]host=127.0.0.1port=3306user=monitorpassword=123456

重启 mysqld_exporter 

nohup /usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf &netstat -ntlup | grep 9104

 四.修改 prometheus 配置⽂件

添加被监控主机

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"]- job_name: 'node2'static_configs:- targets: ['192.168.80.11:9100']- job_name: 'node-mysql'static_configs:- targets: ['192.168.80.11:9104']

重启 prometheus

pkill prometheus
/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml &

 检查 Targets

 五.安装 Grafana

 下载 Grafana

wget https://dl.grafana.com/oss/release/grafana-9.1.5.linux-amd64.tar.gz
tar -zxvf grafana-9.1.5.linux-amd64.tar.gz
ln -s grafana-9.1.5 grafana

 启动 grafana

cd grafana
./bin/grafana-server &

登录 grafana

初始账号密码：admin/admin

六.导入主机

Add data source 

 这个 1860 对应的模板地址是 https://grafana.com/grafana/dashboards/1860-node-exporter-full/

查看效果

七.导入mysql

导⼊⽅式同上，只不过对应的 ID 是 7362。

https://grafana.com/grafana/dashboards/7362-mysql-overview/

完成。
