Prometheus普罗米修斯之安装配置使用

Prometheus普罗米修斯之安装配置使用

一、基础环境

环境/组件 版本 下载地址
操作系统 CentOS7.6
go 1.15.7 https://golang.org/dl/
Prometheus 2.6.0 https://prometheus.io/download/#prometheus
Grafana 5.4.2 https://dl.grafana.com/oss/release/grafana-5.4.2-1.x86_64.rpm

二、安装go

1.解压安装

tar -C /usr/local/ -xvf go1.15.7.linux-amd64.tar.gz

2.配置环境变量

vim /etc/profile

export PATH=$PATH:/usr/local/go/bin

source /etc/profile

3.验证

go version

三、安装Prometheus

1.安装

tar -C /usr/local/ -xvf prometheus-2.28.1.linux-amd64.tar
ln -sv /usr/local/prometheus-2.28.1.linux-amd64/ /usr/local/Prometheus

2.注册服务

tee /etc/systemd/system/prometheus.service <<EOF
[Unit]
Description=Prometheus
Documentation=https://prometheus.io/
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/Prometheus \
  --config.file=/usr/local/Prometheus/prometheus.yml \
  --web.listen-address=:9090
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF

3.启动

systemctl status prometheus
systemctl start prometheus
systemctl enable prometheus

4.登录验证

浏览器打开IP:9090端口即可打开普罗米修斯自带的监控页面

四、安装Grafana

普罗米修斯默认的页面可能没有那么直观,我们可以安装grafana使监控看起来更直观

1.安装

yum install -y grafana-5.4.2-1.x86_64.rpm

yum源无法使用时强制rpm安装

rpm -ivh --nodeps grafana-5.4.2-1.x86_64.rpm

2.启动

systemctl daemon-reload
systemctl enable grafana-server.service
systemctl start grafana-server.service

3.访问grafana

浏览器访问IP:3000端口,即可打开grafana页面,默认用户名密码都是admin

初次登录会要求修改默认的登录密码

五、一些常用监控举例

1、监控linux机器(node-exporter)

被监控的机器安装node-exporter

tar  -zxvf  node_exporter-0.17.0.linux-amd64.tar.gz -C /usr/local/

注册node-exporter 服务

vim /etc/systemd/system/node_exporter.service
[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target

[Service]
Type=simple
ExecStart=/usr/local/node_exporter/node_exporter

[Install]
WantedBy=default.target

启动服务

systemctl status node_exporter
systemctl start node_exporter
systemctl enable node_exporter

普罗米修斯配置文件添加监控项

vi /usr/local/Prometheus/prometheus.yml

默认node-exporter端口为9100

  - job_name: 'node_exporter'
    static_configs:
    - targets: ['192.168.0.102:9100']
      labels:
        instance: Prometheus

重启普罗米修斯

systemctl restart prometheus

grafana导入画好的dashboard模板

如果没有任何显示,是grafana缺少相关显示需要用到的插件piechart,grafana的默认插件目录是/var/lib/grafana/plugins,可以将下载好的插件解压到这个目录,重启grafana即可

service grafana-server restart
# 查看已安装插件
/usr/sbin/grafana-cli plugins ls

再刷新grafana页面,即可看到我们刚才设置好的node监控

2.监控MySQL(mysqld-exporter)

被监控mysql机器安装mysqld-exporter

tar -C /usr/local/ -xvf mysqld_exporter-0.11.0.linux-amd64.tar

设置配置文件,user为数据库登录用户,password为这个用户的密码

vi .my.cnf

[client]
user=root
password=123456

启动mysqld-exporter 也可注册服务与node-exporter同理

/usr/local/mysqld_exporter-0.11.0.linux-amd64/mysqld_exporter --config.my-cnf="/usr/local/mysqld_exporter-0.11.0.linux-amd64/.my.cnf" &

prometheus配置文件中加入mysql监控并重启

vim /usr/local/Prometheus/prometheus.yml

# 默认mysqld-exporter端口为9104
- job_name: 'MySQL'
    static_configs:
    - targets: ['192.168.0.103:9104']

设置数据源

grafana界面添加mysql数据源

添加需要被监控的数据库及相关信息

导入已经画好的dashboard,数据源选择刚刚创建好的mysql数据源即可

dashboard-mysql.json

This serialization is true not only for SELECTs, but also for INSERT/UPDATE/DELETE.\n\nThis also means that the larger the `query_cache_size` is set to, the slower those operations become. In concurrent environments, the MySQL Query Cache quickly becomes a contention point, decreasing performance. MariaDB and AWS Aurora have done work to try and eliminate the query cache contention in their flavors of MySQL, while MySQL 8.0 has eliminated the query cache feature.\n\nThe recommended settings for most environments is to set:\n  ``query_cache_type=0``\n  ``query_cache_size=0``\n\nNote that while you can dynamically change these values, to completely remove the contention point you have to restart the database.",

3.监控Redis(redis_exporter)

安装redis_exporter

tar -C /usr/local/ -xvf redis_exporter-v0.15.0.linux-amd64.tar

启动redis_exporter

默认redis_exporter端口为9121

/usr/local/redis_exporter redis//192.168.0.103:6379 & -web.listenaddress 192.168.0.103:9121

prometheus配置文件中加入redis监控并重启

vim /usr/local/Prometheus/prometheus.yml

# 默认redis-exporter端口为9121
- job_name: 'Redis'
    static_configs:
    - targets: ['192.168.0.103:9121']
