安装mysqld_exporter

赋权

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';

创建.my.cnf文件

cd /usr/local/mysqld_exporter
cat << EOF > .my.cnf
[client]
user=exporter
password=abc123
EOF

创建systemd服务

cat < /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

启动myslqd_exporter

systemctl daemon-reload
systemctl start mysqld_exporter
systemctl status mysqld_exporter
systemctl enable mysqld_exporter

验证

curl localhost:9104/metrics

拉取数据

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
