Prometheus Grafana监控安装配置教程

一、下载Prometheus

https://prometheus.io/download/

二、关闭防火墙

[root@grafana ~]# systemctl disable firewalld.service
[root@grafana ~]# systemctl stop firewalld.service

二、安装Prometheus

[root@grafana tmp]# tar xvf prometheus-2.33.3.linux-amd64.tar.gz -C /usr/local/

[root@grafana tmp]# cd /usr/local/

[root@grafana local]# ln -s prometheus-2.33.3.linux-amd64 prometheus

三、创建数据目录

[root@grafana ~]# mkdir -p /data/prometheus/data 

四、创建用户并授权

[root@grafana ~]# groupadd prometheus
[root@grafana ~]# useradd -g prometheus prometheus
[root@grafana ~]# id prometheus
uid=1001(prometheus) gid=1001(prometheus) groups=1001(prometheus)

[root@grafana ~]# echo -e "prometheus"|passwd --stdin prometheus

[root@grafana ~]# chown -R prometheus.prometheus /usr/local/prometheus /data/prometheus

五、查看帮助文件

./prometheus --help
./prometheus --version

六、启动

两种启动方式二选一:　1.添加systemd服务启动，2.使用脚本手工启动

1.Sytemed启动

配置systemd服务:

[root@grafana ~]# cat > /usr/lib/systemd/system/prometheus.service <<EOF
[Unit]
Description=prometheus
Documentation=https://prometheus.io/
After=network.target
[Service]
Type=simple
User=prometheus
Group=prometheus
ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/data/prometheus/data
Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF

启动:
[root@grafana ~]# systemctl daemon-reload
[root@grafana ~]# systemctl enable prometheus.service
[root@grafana ~]# systemctl start prometheus.service

2.脚本启动

[root@grafana ~]# su - prometheus
[prometheus@grafana ~]$ cd /usr/local/prometheus
[prometheus@grafana prometheus]$  nohup ./prometheus --config.file="prometheus.yml" --storage.tsdb.path=/data/prometheus/data &> /dev/null &

## 查看端口(默认9090)
[root@grafana prometheus]# ss -tnlp |grep 9090
LISTEN     0      128         :::9090
:::*                   users:(("prometheus",pid=70319,fd=7))

[root@grafana prometheus]# ps -ef |grep prometheus

七、Web控制台登录
