1.环境说明

监控主机	被监控主机
192.168.0.66	192.168.0.67
运维主机	MySQL

2.主机安装Prometheus

下载：https://prometheus.io/download/

上传到主机
[root@localhost ~]# yum -y ×××tall vim lrzsz

3.安装go

[root@localhost ~]# yum -y ×××tall epel-release [root@localhost ~]# yum -y ×××tall go Prometheus解压即可用 [root@localhost ~]# tar xf prometheus-2.10.0.linux-amd64.tar.gz -C /usr/local/

4.安装编辑Prometheus配置文件

[root@localhost ~]# vim /usr/local/prometheus-2.10.0.linux-amd64/prometheus.yml 追加如下内容（前方空格一定要对齐）：   - job_name: system-status     static_configs:     - targets: ['192.168.0.67:9100']       labels:         ×××tance: 7-7   - job_name: mysql-status     static_configs:     - targets: ['192.168.0.67:9104']       labels:         ×××tance: 7-7-mysql

5.启动Prometheus

[root@localhost ~]# systemctl stop firewalld [root@localhost ~]# cd /usr/local/prometheus-2.10.0.linux-amd64/ [root@localhost prometheus-2.10.0.linux-amd64]# ./prometheus --config.file=prometheus.yml &    # &意为后台启动

Prometheus页面如下

6.配置被监控服务器

（1）、node_exporter 用于监控操作系统的性能和运行状态(官网自行下载)
（2）、mysqld_exporter 用于监控 mysql 服务(官网自行下载)
（3）、snmp_exporter 用于监控网络设备
更多 exporter 可在官网下载：https://prometheus.io/download/#node_exporter

7.mysql安装和授权

[root@localhost ~]# yum -y ×××tall mariadb mariadb-server [root@localhost ~]# systemctl restart mariadb [root@localhost ~]# mysql Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 2 Server version: 5.5.60-MariaDB MariaDB Server  Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.  Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.  MariaDB [(none)]>  GRANT REPLICATION CLIENT,PROCESS ON *.* TO 'mysql_monitor'@'localhost'     -> identified by '123456'; Query OK, 0 rows affected (0.00 sec)  MariaDB [(none)]> GRANT SELECT ON *.* TO 'mysql_monitor'@'localhost'; Query OK, 0 rows affected (0.00 sec)  MariaDB [(none)]> exit Bye

8.安装主机监控的node_exporter

[root@localhost ~]# tar xf node_exporter-0.17.0.linux-amd64.tar.gz -C /usr/local/ [root@localhost ~]# /usr/local/node_exporter-0.17.0.linux-amd64/node_exporter &

9.安装主机监控的mysql_exporter

[root@localhost ~]# tar xf mysqld_exporter-0.11.0.linux-amd64.tar.gz -C /usr/local/ [root@localhost ~]# vim /usr/local/mysqld_exporter-0.11.0.linux-amd64/.my.cnf 写入如下内容： [client] user=mysql_monitor password= 123456 启动 [root@localhost ~]# cd /usr/local/mysqld_exporter-0.11.0.linux-amd64/ [root@localhost mysqld_exporter-0.11.0.linux-amd64]# ./mysqld_exporter --config.my-cnf=".my.cnf"   &

后台启动的“ & ” 一定要写，不然推出当前操作终端后就会自动关掉
再次刷新Prometheus时，页面被监控都为up

10.安装grafana

下载：https://grafana.com/grafana/download
上传到运维主机

[root@localhost ~]# yum -y ×××tall /root/grafana-6.2.2-1.x86_64.rpm 下载饼状图插件，便于美化数据 [root@localhost ~]# grafana-cli plug××× ×××tall grafana-piechart-panel 启动grafana [root@localhost ~]# systemctl restart grafana-server
