prometheus+grafana监控mysql、canal服务器
一、prometheus配置
1.prometheus安装
1.1官网下载安装包：https://prometheus.io/download/
1.2解压安装包：tar -zxvf prometheus-2.6.1.linux-amd64.tar.gz
1.3快速启动：进入解压目录并启动：./prometheus 默认使用解压目录下的prometheus.yml配置文件】
2.优化prometheus启动、停止
2.1创建日志记录文件：touch /var/log/prometheus.log
2.2添加服务prometheus服务：
$ cd /usr/lib/systemd/system
$ vim prometheus.service
prometheus.service内容
[Unit]
Description=Prometheus
Documentation=https://prometheus.io/docs/introduction/overview/
Wants=network-online.target
After=network-online.target
[Service]
#User=prometheus # 必须用该用户和相应的执行权限否则不能启动
#Group=prometheus
User=root
Group=root
Type=simple
ExecStart=/opt/prometheus/prometheus.sh # 启动脚本
[Install]
WantedBy=multi-user.target2.3启动脚本：vim /opt/prometheus/prometheus.sh
#!/bin/bash
/root/prometheus/prometheus-2.6.1.linux-amd64/prometheus --config.file=/root/prometheus/prometheus-2.6.1.linux-amd64/prometheus.yml &>> /var/log/prometheus.log2.4启动、停止脚本：systemctl start prometheus.service / systemctl stop prometheus.service
2.5进入登录页面：ip:9090
二、安装grafana(centos)
1.1不同的操作系统具体参考官网：http://docs.grafana.org/
1.2(centos)，配置文件为：/opt/grafana/grafana.ini
yum install https://dl.grafana.com/oss/release/grafana-5.4.2-1.x86_64.rpm1.3启动：systemctl start grafana-server
1.4登录页面：ip:3000,账号密码默认：admin/admin
三、prometheus配置mysql
1.安装node_export、mysqld_export
#安装node_export
wget https://github.com/prometheus/node_exporter/releases/download/v0.14.0/node_exporter-0.14.0.linux-amd64.tar.gz -O node_exporter-0.14.0.linux-amd64.tar.gz
#安装mysqld_exporter
wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.10.0/mysqld_exporter-0.10.0.linux-amd64.tar.gz -O mysqld_exporter-0.10.0.linux-amd64.tar.gz
#创建目录
mkdir /usr/local/services
mkdir /usr/local/services/prometheus_exporters
#解压node_export
tar zxf node_exporter-0.14.0.linux-amd64.tar.gz -C /usr/local/services/prometheus_exporters --strip-components=1
#解压mysqld_exporter
tar zxf mysqld_exporter-0.10.0.linux-amd64.tar.gz -C /usr/local/services/prometheus_exporters --strip-components=11.2优化启动过程，类似prometheus
node_export进入解压目录直接启动: ./node_exporter
mysqld_export 进入解压目录直接启动：./mysqld_exporter -config.my-cnf=my.cnf
需要配置数据连接信息：需要注意权限问题
#解压文件夹目录创建文件
vim my.cnf
#内容,数据库账号密码
[client]
user=root
password=123456
port=3306
1.3启动node_export与mysqld_export
2.prometheus配置mysql
2.1修改prometheus.yml配置文件：
#修改
vim prometheus.yml
#添加：
- job_name: 'mysql'
static_configs:
- targets: ['192.168.1.158:9104']
labels:
instance: 192.168.1.158
- job_name: 'linux'
static_configs:
- targets: ['192.168.1.158:9100']
labels:
instance: db12.2重启服务,页面会看到
3.grafana配置
3.1Add prometheus datasource
2.添加mysql仪表盘：import 仪表盘
官网查询：Mysql overView https://grafana.com/dashboards?search=MySql%20Ov
选择datasource 为 Prometheus
四、增加canal监听
1.1修改prometheus配置文件
vim prometheus.yml
#增加内容
- job_name: 'canal'
static_configs:
- targets: ['localhost:11112']#canal服务ip1.2grafana配置，增加canal仪表盘信息，如上，不过这次不是从官网下载，而是import外部文件
见下面：canal_instance.json
1.3重启服务可看到
canal_instance.json
