安装loki

1、关闭selinux
2、安装docker

yum install docker -y

3、安装loki

# 下载配置文件
wget https://raw.githubusercontent.com/grafana/loki/v2.5.0/cmd/loki/loki-local-config.yaml -O loki-config.yaml

# docker启动
docker run --name loki -d -v $(pwd):/mnt/config -p 3100:3100 grafana/loki:2.5.0 -config.file=/mnt/config/loki-config.yaml

4、查看loki状态

[root@localhost ~]# docker ps
