前置工作
- Centos 7
- 关闭防火墙 (systemctl stop firewalld)
- 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 software
mkdir -p packages
Grafana
# 切换目录
cd packages
# 下载grafana
wget 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

# 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:
