loki: 安装配置Loki v3.2.1

一，Loki是什么？

1, Loki 是 Grafana 团队开源的一款高可用、高拓展、多租户的日志聚合系统，
和 ELK 的组件功能一样，Loki 有负责日志存储查询的主服务，有在客户端负责收集日志并推送的代理服务，
还有 Grafana 最拿手的可视化面板展示。

2,官方网站

https://grafana.com/oss/loki/

下载地址:

https://github.com/grafana/loki/releases/

二，下载

用wget从命令行下载

# wget https://github.com/grafana/loki/releases/download/v3.2.1/loki-3.2.1.x86_64.rpm

三，安装

用rpm命令执行安装

# rpm -ivh loki-3.2.1.x86_64.rpm
warning: loki-3.2.1.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 10458545: NOKEY

四，配置

1,查看状态

安装完成后已经处理运行状态，
因为是rpm包装，已默认支持用systemctl管理服务

# systemctl status loki.service
● loki.service - Loki service
     Loaded: loaded (;;file://backup/etc/systemd/system/loki.service/etc/systemd/system/loki.service;;; enabled; preset: disabled)
     Active: active (running) since Tue 2024-10-29 16:41:49 CST; 1min 42s ago
   Main PID: 471546 (loki)
      Tasks: 13 (limit: 97114)
     Memory: 52.9M
        CPU: 414ms
     CGroup: /system.slice/loki.service
             └─471546 /usr/bin/loki -config.file /etc/loki/config.yml

2,查看端口:
可以看到已经绑定了两个端口: 3100/9096

# ss -lntp | grep loki
LISTEN 0      4096                    *:3100             *:*    users:(("loki",pid=471546,fd=9))
LISTEN 0      4096                    *:9096             *:*    users:(("loki",pid=471546,fd=10))
