技术标签： Prometheus和Grafana的监控Linux服务器和 node_exporter Prometheus Grafana
【使用root用户执行以下操作】
目录
4）我们访问Prometheus :http://100.100.100.25:9090
4)监听端口为9100，我们访问 http://100.100.100.25:9100
5)配置Prometheus，将node_exporter加入到监控中
6）在grafana中的配置 （http://100.100.100.25:3000）
2)将下载的mysqld_exporter上传到mysql所在的linux服务器
3）在root目录下建立文件 " .my.cnf " ，输入mysql的访问参数
4)启动mysqld_exporter,指定监听端口为9200
5）我们访问 mysqld_exporter : http://100.100.100.25:9200
6)修改prometheus配置,在prometheus.yml加入mysql的监听地址
8）访问grafana（http://100.100.100.25:3000），将mysql数据源添加
10）将my2.sql导入到MYSQL数据库(100.100.100.25:3306/pig)，该监控就是利用my2.sql中的数据进行展示的
一、安装Prometheus和Grafana
1、安装 Prometheus
- Prometheus(中文名:普罗米修斯)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。
- Prometheus的基本原理是通过HTTP协议周期性抓取被监控组件的状态, 任意组件只要提供对应的HTTP接口就可以接入监控. 不需要任何SDK或者其他的集成过程。输出被监控组件信息的HTTP接口被叫做exporter，目前开发常用的组件大部分都有exporter可以直接使用, 比如Nginx、MySQL、Linux系统信息、Mongo、ES等
1）下载 Prometheus
- github链接： https://github.com/prometheus/prometheus/releases/
- 选择最新的版本进行下载：prometheus-2.15.1.linux-amd64.tar.gz
- 将下载的安装包上传到linux服务器
2）解压安装包
tar -zxvf prometheus-2.15.1.linux-amd64.tar.gz
3）启动prometheus
./prometheus[如果需要挂后台在命令后面加 & 符号]
- 监听端口是9090
4）我们访问Prometheus :http://100.100.100.25:9090
- prometheus安装结束
2、安装Grafana
- Grafana是一个图形化工具, 它可以从很多种数据源(例如Prometheus)中读取数据信息, 使用很漂亮的图表来展示数据, 并且有很多开源的dashborad可以使用,可以快速地搭建起一个非常精美的监控平台。它与Prometheus的关系就类似于Kibana与ElasticSearch。
1）下载 grafana
- grafana下载网址：https://grafana.com/grafana/download?platform=linux
- 选择二进制安装包
wget https://dl.grafana.com/oss/release/grafana-6.5.2.linux-amd64.tar.gz
- 解压grafana
tar -zxvf grafana-6.5.2.linux-amd64.tar.gz
- 在bin目录下启动
./grafana-server
- 监听端口为 3000
- 我们访问 http://100.100.100.25:3000 ,默认的登录用户为admin/admin,后需要修改密码
- grafana安装完成
[准备工作已经完成，下面我们来安装监控Linux服务器的软件和监控mysql数据库的软件]
二、监控Linux服务器
1、安装Node Exporter
- prometheus可以理解为一个数据库 数据抓取工具, 工具从各处抓来统一的数据, 放入prometheus这一个时间序列数据库中. 那如何保证各处的数据格式是统一的呢?就是通过这个exporter. Exporter是一类数据采集组件的总称. Exporter负责从目标处搜集数据, 并将其转化为Prometheus支持的格式, 它开放了一个http接口(以便Prometheus来抓取数据). 与传统的数据采集组件不同的是, Exporter并不向中央服务器发送数据, 而是等待中央服务器(如Prometheus等)主动前来抓取。https://github.com/prometheus 有很多写好的exporter,可以直接下载使用。
1）下载node_exporter
- 从github上进行下载：https://github.com/prometheus/node_exporter/releases
- 选择最新版本下载： node_exporter-0.18.1.linux-amd64.tar.gz
2）将安装包上传到linux
- 解压安装包
tar -zxvf node_exporter-0.18.1.linux-amd64.tar.gz
3)启动node_exporter
./node_exporter
4)监听端口为9100，我们访问 http://100.100.100.25:9100
5)配置Prometheus，将node_exporter加入到监控中
- 编辑Prometheus配置文件
vim prometheus.yml- 加入node_exporter监控配置
- 修改完成后启动Prometheus
./prometheus6）在grafana中的配置 （http://100.100.100.25:3000）
-
添加Prometheus数据源
- 添加prometheus数据源完成
7）导入Prometheus监控Linux模板
- 从grafana下载Prometheus模板： https://grafana.com/grafana/dashboards?dataSource=prometheus
- 下载sjon格式的模板
- 回过头来将下载的json上传到grafana
- 选择Prometheus数据源
8）配置prometheus监控linux服务器完成
三、监控MYSQL数据库(Linux版本)
1)下载mysqld_exporter
- 从github上下载:https://github.com/prometheus/mysqld_exporter/releases
- 选择最新的linux版本: mysqld_exporter-0.12.1.linux-amd64.tar.gz
2)将下载的mysqld_exporter上传到mysql所在的linux服务器
- 解压
tar -zxvf mysqld_exporter-0.12.1.linux-amd64.tar.gz
3）在root目录下建立文件 " .my.cnf " ，输入mysql的访问参数
vi /root/.my.cnf[文件内容如下]
[client]
host = 100.100.100.25
user = root
password = password4)启动mysqld_exporter,指定监听端口为9200
./mysqld_exporter --web.listen-address=":9200" &5）我们访问 mysqld_exporter : http://100.100.100.25:9200
6)修改prometheus配置,在prometheus.yml加入mysql的监听地址
vim prometheus.yml[增加的内容]
- job_name: '100.100.100.25_mysql'
static_configs:
- targets: [100.100.100.25:9200]
7）重启Prometheus
./prometheus8）访问grafana（http://100.100.100.25:3000），将mysql数据源添加
- 填写完mysql数据源的信息后，点击左下角的Save & Test 即可
9）添加mysql仪表模板
- 从grafana官网下载 ： https://grafana.com/grafana/dashboards?dataSource=mysql
- 下载JSON格式的模板
- 回过头来，将下载的模板上传到grafana中
10）将my2.sql导入到MYSQL数据库(100.100.100.25:3306/pig)，该监控就是利用my2.sql中的数据进行展示的
- 从github上下载：https://github.com/john1337/my2Collector/blob/master/my2.sql
- 该文件的内容如下：

mysqld_exporter.exe --web.listen-address=":9104" --config.my-cnf=.my.cnf- 访问9104端口
4)在Prometheus配置中增加对该mysql的监听
vim prometheus.yml
- 启动Prometheus
./prometheus5)在grafana上(http://100.100.100.25:3000/)增加该数据源
6)选择MYSQL监控仪表盘
- 选择刚刚添加的MYSQL数据源
【访问Prometheus ，http://100.100.100.25:9090 可以看到在配置中添加的监听服务器】

JS重写Date函数，兼容IOS系统_date.prototype 将所有 ios-程序员宅基地
文章浏览阅读1.8k次，点赞5次，收藏8次。IOS系统Date的坑要创建一个指定时间的new Date对象时，通常的做法是：new Date("2020-09-21 11:11:00")这行代码在 PC 端和安卓端都是正常的，而在 iOS 端则会提示 Invalid Date 无效日期。在IOS年月日中间的横岗许换成斜杠，也就是new Date("2020/09/21 11:11:00")通常为了兼容IOS的这个坑，需要做一些额外的特殊处理，笔者在开发的时候经常会忘了兼容IOS系统。所以就想试着重写Date函数，一劳永逸，避免每次ne_date.prototype 将所有 ios
