Prometheus+Grafana部署配置
Prometheus安装
下载Prometheus服务端

https://prometheus.io/download/
上传至服务器，解压
tar -zxvf prometheus-3.0.1.linux-amd64.tar.gz
cd prometheus-3.0.1.linux-amd64
运行
./prometheus --config.file="prometheus.yml"后台运行
nohup ./prometheus --config.file=prometheus.yml &
当首次访问9090端口时，时间序列数据的洪流如同宇宙背景辐射般扑面而来。

在被监控端主机解压这两个文件
tar -zxvf node_exporter-1.8.2.linux-amd64.tar.gz
node_exporter插件可直接运行cd node_exporter-1.8.2.linux-amd64node_exporter插件可直接运行
cd node_exporter-1.8.2.linux-amd64
nohup ./node_exporter &
mysqld_exporter需要连接到MySQL,需要授权
mysqld_exporter插件需要创建一个用户+密码的文件
tar -zxvf mysqld_exporter-0.16.0.linux-amd64.tar.gz
cd mysqld_exporter-0.16.0.linux-amd64
mysql> use mysql;mysql> create user dbuser;
mysql> GRANT REPLICATION CLIENT, PROCESS ON *.* TO 'dbuser'@'localhost' identified by '123456';
mysql> GRANT SELECT ON performance_schema.* TO 'dbuser'@'localhost';
创建 .my.cnf 加入以下内容
[client]user=dbuserpassword=123456
启动mysqld_exporter
nohup ./mysqld_exporter --config.my-cnf=.my.cnf &
Prometheus服务端添加被监控端
cd prometheus-3.0.1.linux-amd64vi prometheus.yml 加入- job_name: system-statusstatic_configs:- targets: ['192.168.126.50:9100']labels:instance: 7-7- job_name: mysql-statusstatic_configs:- targets: ['192.168.126.40:9104']labels:instance: 7-7-mysql
