修改主机名
[root@localhost ~]# hostnamectl set-hostname prometheus [root@localhost ~]# bash
关闭防火墙
[root@prometheus ~]# systemctl disable --now firewalld
关闭selinux
[root@prometheus ~]# vim /etc/selinux/config [root@prometheus ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # disabled - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of disabled. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted [root@prometheus ~]# reboot [root@prometheus ~]# getenforce Disabled
首先配置yum仓库
[root@prometheus ~]# wget -O /etc/yum.repos.d/CentOS-base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
配置docker的yum源
[root@prometheus ~]# cd /etc/yum.repos.d/ [root@prometheus ~]# curl -o docker-ce.repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo [root@prometheus ~]# sed -i 's@https://download.docker.com@https://mirrors.tuna.tsinghua.edu.cn/docker-ce@g' docker-ce.repo
安装docker-ce以及docker组件
[root@prometheus ~]# yum -y install docker-ce
启动docker
[root@prometheus ~]# systemctl start docker
[root@prometheus ~]# systemctl status docker

运行promethues容器
拉取官方prometheus镜像
[root@prometheus ~]# docker pull prom/prometheus Using default tag: latest latest: Pulling from prom/prometheus 3cb635b06aa2: Pull complete 34f699df6fe0: Pull complete 33d6c9635e0f: Pull complete f2af7323bed8: Pull complete c16675a6a294: Pull complete 827843f6afe6: Pull complete 3d272942eeaf: Pull complete 7e785cfa34da: Pull complete 05e324559e3b: Pull complete 170620261a59: Pull complete ec35f5996032: Pull complete 5509173eb708: Pull complete Digest: sha256:cb9817249c346d6cfadebe383ed3b3cd4c540f623db40c4ca00da2ada45259bb Status: Downloaded newer image for prom/prometheus:latest docker.io/prom/prometheus:latest
创建存放prometheus配置文件的目录，并提供默认配置文件
[root@prometheus ~]# mkdir -p /prometheus/config/
[root@prometheus ~]# cd /prometheus/config/
[root@prometheus config]# vim prometheus.yml
[root@prometheus config]# cat prometheus.yml
