mysqld_exporter是用来搜集mysql的性能指标的,适用于mysql5.5及其以上版本
下载地址：https://prometheus.io/download/#mysqld_exporter
tar -zxvf mysqld_exporter-0.11.0.linux-amd64.tar.gz
mv mysqld_exporter-0.11.0.linux-amd64 /usr/local/mysqld_exporter
mysqld_exporter需要连接到Mysql，所以需要Mysql的权限，我们先为它创建用户并赋予所需的权限：
CREATE USER ‘exporter‘@‘localhost‘ IDENTIFIED BY ‘abc123‘ WITH MAX_USER_CONNECTIONS 3; GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO ‘exporter‘@‘localhost‘;
cd /usr/local/mysqld_exporter cat << EOF > .my.cnf [client] user=exporter password=abc123 EOF
cat <<EOF > /etc/systemd/system/mysqld_exporter.service [Unit] Description=mysqld_exporter After=network.target [Service] Type=simple User=prometheus ExecStart=/usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf Restart=on-failure [Install] WantedBy=multi-user.target EOF
systemctl daemon-reload
systemctl start mysqld_exporter
systemctl status mysqld_exporter
systemctl enable mysqld_exporter
curl localhost:9104/metrics
利用 Prometheus 的 static_configs 来拉取 mysqld_exporter 的数据。
编辑prometheus.yml文件，添加内容
- job_name: ‘mysql‘ static_configs: - targets: [‘localhost:9104‘]
重启prometheus，然后在Prometheus页面中的Targets中就能看到新加入的mysql
搜索mysql的Grafana Dashboard，导入进去
