Prometheus的安装和配置教程详解

1. 从官网选择Prometheus版本进行下载

官网地址>> https://github.com/prometheus/prometheus/releases/

2. 实验安排

在主机192.168.153.137上安装prometheus监控192.168.153.138上的mysql服务和主机状态

3. 上传软件包到137服务器并配置

3.1 将软件包解压到 /usr/local 目录下

tar xzf prometheus-2.24.1.linux-amd64.tar.gz -C /usr/local/

3.2 给目录创建软链接

ln -s /usr/local/prometheus-2.24.1.linux-amd64/ /usr/local/prometheus

3.3 切换到目录下

cd /usr/local/prometheus

3.4 修改配置文件 prometheus.yml，配置要监控的项

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] #监控Linux主机状态 – job_name: linux static_configs: – targets: [192.168.153.138:9100] #监控mysql服务状态 – job_name: mysql static_configs: – targets: [192.168.153.138:9104]

3.5 启动promethus服务

./prometheus –config.file=prometheus.yml

3.6 浏览器输入 IP:9090 查看

在Status->Targets页面下，我们可以看到我们配置的两个Target，它们的State为DOWN。

4. 配置138主机 4.1 下载exporter

下载地址>> https://github.com/prometheus/node_exporter/releases

4.2 将软件包解压到 /usr/local 目录下

tar xzf node_exporter-1.0.1.linux-amd64.tar.gz -C /usr/local/

4.3 启动exporter

nohup /usr/local/node_exporter-1.0.1.linux-amd64/node_exporter &

4.4 下载mysqld_exporter

下载地址>> https://github.com/prometheus/mysqld_exporter/releases

4.5 将软件包解压到 /usr/local 目录下

tar xzf mysqld_exporter-0.12.1.linux-amd64.tar.gz -C /usr/local/

4.6 数据库给mysqld_exporter授权

[root@host-138 ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or g. MariaDB [(none)]> GRANT REPLICATION CLIENT,PROCESS ON *.* TO mysql_monitor@localhost identified by mysql_monitor; 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)

4.7 创建 .my.cnf 配置文件

vim /usr/local/mysqld_exporter-0.12.1.linux-amd64/.my.cnf

内容为：

[client] user=mysql_monitor password=mysql_monitor

4.8 运行mysqld_exporter服务

nohup /usr/local/mysqld_exporter-0.12.1.linux-amd64/mysqld_exporter –config.my-cnf=”/usr/local/mysqld_exporter-0.12.1.linux-amd64/.my.cnf” &

5. 在promethus页面刷新Status->Targets页面，可以看到配置的两个Target的State为UP：

5. 在137主机上安装部署grafana
