关注公众号，技术道路不迷路
1、安装Prometheus
官方地址：https://prometheus.io/download/
wget https://github.com/prometheus/prometheus/releases/download/v2.7.2/prometheus-2.7.2.linux-amd64.tar.gz
上传至任意目录即可。
[root@my opt]# tar -xvf prometheus-2.26.0.linux-amd64.tar.gz
[root@my opt]# cd prometheus-2.26.0.linux-amd64/
[root@my prometheus-2.26.0.linux-amd64]# ./prometheus --config.file=prometheus.yml &
输入： “ip地址”+":9090" 在浏览器中进行访问，如果出现可视化界面说明成功；
http://192.168.59.132:9090/
2、添加主机监控
wget https://github.com/prometheus/node_exporter/releases/download/v0.17.0/node_exporter-0.17.0.linux-amd64.tar.gz
[root@my opt]# tar -xvf node_exporter-1.8.2.linux-amd64.tar.gz
[root@my opt]# cd node_exporter-1.8.2.linux-amd64/
[root@my node_exporter-1.8.2.linux-amd64]# ./node_exporter &
• 本Centos中访问： curl http://localhost:9100/metrics
• 电脑浏览器中访问： ip地址:9100
http://192.168.59.132:9100
去Prometheus的配置文件中加上这个exporter的地址
[root@my prometheus-2.26.0.linux-amd64]# vi prometheus.yml
添加以下内容
- job_name: 'server'
static_configs:
- targets: ['localhost:9100']
3、安装Grafana
wget https://dl.grafana.com/oss/release/grafana-6.0.0.linux-amd64.tar.gz
[root@my opt]# tar -xvf grafana-6.0.0.linux-amd64.tar.gz
[root@my opt]# cd grafana-6.0.0/
[root@my grafana-6.0.0]# ./bin/grafana-server web &
浏览器输入 IP:3000 来访问Grafana.
管理员账号密码默认是admin/admin。首次登陆会提示修改管理员密码。
http://192.168.59.132:3000
添加数据源
选择Prometheus
先输入名称，然后填入http://ip+9090然后直接点Save&Test，成功后则直接点击Dashboards选择展示面板

4、添加其他机器主机监控
其他机器上安装node_exporter即可。
[root@localhost opt]# tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz
[root@localhost opt]# chown -R root:root node_exporter-0.18.1.linux-amd64
[root@localhost opt]# cd node_exporter-0.18.1.linux-amd64/
[root@localhost node_exporter-0.18.1.linux-amd64]# ./node_exporter &
重启服务即可。
5、添加MySQL监控
下载地址：https://github.com/prometheus/mysqld_exporter/releases/download/v0.15.1/mysqld_exporter-0.15.1.linux-amd64.tar.gz
也可以在网盘下载：
通过网盘分享的文件：mysqld_exporter-0.11.0.linux-amd64.tar.gz
链接: https://pan.baidu.com/s/1370ATIF1T3_0ftPOl-IYeQ 提取码: trc5
[root@localhost opt]# tar -xvf mysqld_exporter-0.11.0.linux-amd64.tar.gz
[root@localhost opt]# cd mysqld_exporter-0.11.0.linux-amd64/
[root@localhost mysqld_exporter-0.11.0.linux-amd64]# vi .my.cnf
添加
[client]
user=root
password=123456
port=3306
[root@localhost mysqld_exporter-0.11.0.linux-amd64]# nohup ./mysqld_exporter --config.my-cnf=".my.cnf" &
浏览器访问：http://IP:9104
http://192.168.59.141:9104/
在prometheus.yml中加入job
[root@my prometheus-2.26.0.linux-amd64]# vi prometheus.yml
添加以下内容：
- job_name: 'mysql'
static_configs:
- targets: ['localhost:9104']
[root@my prometheus-2.26.0.linux-amd64]# nohup ./prometheus --config.file=prometheus.yml &
浏览器访问：
http://192.168.59.132:9090/
下载granfana模板
地址：https://grafana.com/grafana/dashboards/7362-mysql-overview/
导入下载的json文件
其他中间件监控可以自行下载添加即可。
