前置工作

  1. Centos 7
  2. 关闭防火墙 (systemctl stop firewalld)
  3. 独立的用户组(可以不创建)

用户组(按需创建)

# 创建用户组groupadd grafana# 新建一个家目录为`/home/grafana`,用户组为`grafana`,用户名为`grafana`的用户useradd -d /home/grafana -g grafana grafana# 切换用户su - grafana# 创建软件目录及按安装包目录mkdir -p softwaremkdir -p packages

Grafana

# 切换目录cd packages# 下载grafanawget https://dl.grafana.com/enterprise/release/grafana-enterprise-11.1.0.linux-amd64.tar.gz# 解压tar -zxf grafana-enterprise-11.1.0.linux-amd64.tar.gz# 移动目录mv grafana-v11.1.0 ../software# 切换目录cd ../software/grafana-v11.1.0# 启动服务(访问地址: http://ip:3000,默认用户名及密码:admin/admin),若出现无法访问,请检查防火墙状态是否为关闭的状态./bin/grafana server

Loki

# 下载地址:https://github.com/grafana/loki/releases,请根据当前系统版本下载相应的文件,并将下载的文件放到packages目录中# 解压并移动目录unzip loki-linux-amd64.zip -d ../software/loki# 创建loki配置文件touch ../software/loki/loki.yaml# 启动loki服务(-config.file 指定配置文件位置)./loki-linux-amd64 -config.file=loki.yaml

# By default, Loki will send anonymous, but uniquely-identifiable usage and configuration# analytics to Grafana Labs. These statistics are sent to https://stats.grafana.org/## Statistics help us better understand how Loki is used, and they show us performance# levels for most users. This helps us prioritize features and documentation.# For more information on what's sent, look at# https://github.com/grafana/loki/blob/main/pkg/analytics/stats.go# Refer to the buildReport method to see what goes into a report.## If you would like to disable reporting, uncomment the following lines:#analytics:# reporting_enabled: false

Promtail

# 下载地址:https://github.com/grafana/loki/releases,请根据当前系统版本下载相应的文件,并将下载的文件放到packages目录中# 解压并移动目录unzip promtail-linux-amd64.zip -d ../software/promtail# 创建promtail配置文件touch ../software/promtail/promtail.yaml# 启动Promtail服务./promtail-linux-amd64 -config.file=promtail.yaml  -config.expand-env=true
