source /etc/profile（2）将 Go 添加到环境变量，添加到当前用户的 .profile 文件：
hxstrive@localhost:~$ echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile（3）查看 .profile 的内容：
hxstrive@localhost:~$ cat ~/.profile
# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.
# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/usr/local/go/bin（4）使用 source 重新加载 /etc/profile 文件：
hxstrive@localhost:~$ source ~/.profile（5）验证 go 安装是否正确：
hxstrive@localhost:~$ go version
go version go1.21.8 linux/amd64上述成功输出了 go 的版本信息。
（1）解压 node_exporter 安装包：
# 解压到 /usr/local 目录
hxstrive@localhost:~$ sudo tar -zxf node_exporter-0.16.0.linux-amd64.tar.gz -C /usr/local/
[sudo] password for hxstrive:

hxstrive@localhost:~$ sudo mv /usr/local/node_exporter-0.16.0.linux-amd64/ /usr/local/node_exporter
hxstrive@localhost:~$ ls /usr/local/node_exporter/
LICENSE node_exporter NOTICE（3）后台运行 node_exporter：

如果你能看见上面界面，说明安装成功了。
（1）解压 Prometheus 安装包：
# 解压文件
hxstrive@localhost:~$ sudo tar -C /usr/local -zxf prometheus-2.3.2.linux-amd64.tar.gz
# 查看解压后的内容
hxstrive@localhost:~$ ls /usr/local/prometheus-2.3.2.linux-amd64/
console_libraries consoles LICENSE NOTICE prometheus prometheus.yml promtool（2）建立 prometheus 的软链接：
# 创建软链接
hxstrive@localhost:~$ sudo ln -sv /usr/local/prometheus-2.3.2.linux-amd64/ /usr/local/Prometheus
'/usr/local/Prometheus' -> '/usr/local/prometheus-2.3.2.linux-amd64/'
# 查看软链接目录内容
hxstrive@localhost:~$ ls /usr/local/Prometheus
console_libraries consoles LICENSE NOTICE prometheus prometheus.yml promtool（1）使用 vim 编辑 prometheus.yml 配置文件：
hxstrive@localhost:~$ vim /usr/local/Prometheus/prometheus.yml（2）配置内容如下：
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
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']
# node_exporter
- job_name: 'node_exporter'
static_configs:
- targets: ['localhost:9100']上面配置，监听地址为本机 9090 端口 “localhost:9090”。并且还将 node_exporter 添加在配置末尾，监听本机 9100 端口。
使用 & 命令在后台运行 prometheus，命令如下：
hxstrive@localhost:~$ sudo /usr/local/Prometheus/prometheus --config.file=/usr/local/Prometheus/prometheus.yml &
