2.解压并安装软件

tar -zxvf node_exporter-0.18.1.linux-amd64.tar.gz
mv node_exporter-0.18.1.linux-amd64 /usr/local/node_exporter

3.启动node_exporter

cd /usr/local/node_exporter/
nohup ./node_exporter &

4.确认端口9100

ss -anlpt|grep 9100

 

四、监控agent的mysqld服务（192.168.1.172）

1.mysql安装（省略）

2.安装mysqld_exporter

wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.12.1/mysqld_exporter-0.12.1.linux-amd64.tar.gz

3.解压并安装软件

tar -zxvf mysqld_exporter-0.12.1.linux-amd64.tar.gz
mv mysqld_exporter-0.12.1.linux-amd64 /usr/local/mysqld_exporter

4.配置mysql信息

cd /usr/local/mysqld_exporter
vim .my.cnf
​
[client]
user=root
password=root

5.启动mysqld_exporter

nohup /usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf &

6.确认端口9104

lsof -i :9104

 

五、重新配置启动prometheus（192.168.1.171）

1.关闭Prometheus

pkill prometheus

2.进入/usr/local/prometheus编辑prometheus.yml配置文件

- job_name: 'ali-agent'
    static_configs:
    - targets: ['192.168.1.172:9100']
    
- job_name: 'ali-mysql'
    static_configs:
    - targets: ['192.168.1.172:9104']
