CentOS7安装Prometheus(二进制)

一、概述

Prometheus是由SoundCloud开发的开源监控报警系统和时序列数据库(TSDB)。Prometheus使用Go语言开发，是Google BorgMon监控系统的开源版本。

 

环境说明

操作系统：centos 7.6
ip地址：192.168.31.150

 

下载包

https://prometheus.io/download/
目前最新版是：2.14.0
下载链接：
https://github.com/prometheus/prometheus/releases/download/v2.14.0/prometheus-2.14.0.linux-amd64.tar.gz

 

二、安装

useradd prometheus -s /sbin/nologin
tar zxvf prometheus-2.14.0.linux-amd64.tar.gz -C /data
mv /data/prometheus-2.14.0.linux-amd64 /data/prometheus
chown prometheus:prometheus -R /data/prometheus

 

封装service

vi /etc/systemd/system/prometheus.service

 

内容如下：

[Unit]
Description=Prometheus
After=network.target
[Service]
ExecStart=/data/prometheus/prometheus --config.file=/data/prometheus/prometheus.yml --storage.tsdb.path=/data/prometheus/data
User=prometheus
[Install]
WantedBy=multi-user.target

注意：主要修改ExecStart和User

 

设置开机自启动

systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus

 

查看端口

# ss -tunlp|grep prometheus
tcp    LISTEN     0      128      :::9090                 :::*                   users:(("prometheus",pid=969,fd=5))

 

如果是centos 6.x系统，需要自己写一个启动脚本。

vi /etc/init.d/prometheus

内容如下：

#!/bin/bash
# auditd        Start jar package
# chkconfig: 2345 14 87
# description: This is admin project
#define var
PROJECT_SERVICE="prometheus"
PORT="9090"
. /etc/init.d/functions 
export START="nohup /data/prometheus/prometheus --config.file=/data/prometheus/prometheus.yml --storage.tsdb.path=/data/prometheus/data &"
#服务脚本
start(){
    echo "${PROJECT_SERVICE} starting....."
    cd /data/${PROJECT_SERVICE} && eval $START
    if [ $? -eq 0 ];then
            action "$PROJECT_SERVICE is starting" /bin/true
    else
            action "$PROJECT_SERVICE is starting" /bin/false
    fi
}
stop(){
    kill -9 `lsof -t -i:${PORT}`
    if [ $? -eq 0 ];then
        action "$PROJECT_SERVICE is stoping" /bin/true
    else
        action "$PROJECT_SERVICE is stoping" /bin/false
    fi 
}
status(){
    if [ `ss -tunlp|grep ${PROJECT_SERVICE}|awk '{print $5}'|cut -d: -f4` = ${PORT} ];then
            echo "${PROJECT_SERVICE} is running....."
    else
            echo "${PROJECT_SERVICE} is stopping....."
    fi
}
case $1 in
start)
    start
    ;;
stop)
    stop
    ;;
restart)
    stop
    start
    ;;
status)
    status
    ;;
*)
   echo "$0 <start|stop|restart>"
esac

 

添加权限，并启动

chmod 755 /etc/init.d/prometheus
/etc/init.d/prometheus start

 

三、访问页面

访问targets
http://192.168.31.150:9090/targets

 

到这里，安装就结束了。
