centos7 部署Prometheus

前言：

一、前置环境说明

1、关闭firewall

systemctl stop firewalld.service
systemctl disable firewalld.service

2、关闭selinux

vim /etc/selinux/config
SELINUX=disabled

使配置立即生效，重启永久生效

setenforce 0

3、系统约定

软件源代码包存放位置：/opt
源码包编译安装位置：/usr/local/软件名字
数据存储位置：/data

二、部署Prometheus server

1、创建用户

useradd -d /data/prometheus -s /sbin/nologin prometheus 

2、解压软件包

下载地址：https://prometheus.io/download/

tar xzvf prometheus-2.26.0.linux-amd64.tar.gz -C /usr/local/

授权属主属组

chown -R prometheus:prometheus prometheus/
ln -s /usr/local/prometheus-2.26.0.linux-amd64/ /usr/local/prometheus 

已服务启动

cat >> /usr/lib/systemd/system/prometheus.service<<EOF
[Unit]
Description=Prometheus server Daemon
After=network.target
[Service]
Type=simple
User=root
Group=root
ExecStart=/usr/local/prometheus/prometheus  --config.file=/usr/local/prometheus/prometheus.yml  --storage.tsdb.path=/data/prometheus  --storage.tsdb.retention=15d --web.enable-lifecycle
Restart = on-failure
[Install]
WantedBy=multi-user.target
EOF

3、启动服务

systemctl daemon-reload 
systemctl enable prometheus --now 
systemctl start prometheus

查看进程

netstat -tunlp | grep 9090 
cd /usr/local/prometheus 
./promtool check config prometheus.yml

4、访问服务

http://192.168.1.160:9090

至此结束！
